1 INTRODUCTION
This Site Based Stormwater Management Plan (SBSMP) has been prepared by TFA Project Group on behalf of
Synergy Property Partners for the development of a new service station; consisting of paypoint building, a canopy
over fuel dispensing area and associated driveways, vehicle parking and landscape areas. The purpose of this
document is to verify that stormwater quality has been considered as part of this development in accordance with
Planning Scheme Policy 5 – Engineering Design Standards – Roads, Drainage and Earthworks. Noosa Council.
The SBSMP is part of the Development Approval process and addresses both the construction and operational
phases of the development. Table 1 below shows additional details of the proposed development. The proposed
site layout plan is shown in Appendix A.
Table 1: Details of proposed development
Developer Synergy Property Partners
Address 123 Eumundi Road (Cnr Walter Hay Drive) Noosaville QLD 4566
Property Description Lot 30 on SP170751
Area of Development 2448 m²
Stormwater Risk Classification High Risk (due to the storage and transfer on site of petroleum products
that have the potential to cause harm to the environment, if released).
Existing Land Use Vacant Land
2 SITE DESCRIPTION
The development site is bound by Eumundi Noosa Road to the North and West, a School (Lot 1 on SP 228052) to
the East, and by Eumundi Road and Walter Hay Drive to the West and South.
The site currently has a gravel hardstand cleared area at the centre of the lot. There are a few trees around the
North, West and South boundary areas which are maintained in the proposed development site layout plan. A
landscape plan will be prepared for the final form of the development site that will incorporate stormwater measures.
The proposed development takes up the majority of the Western side of Lot 30 on SP170751, as shown in the site
layout plan, leaving the remaining areas undeveloped. An easement at the North of the site will be created to
maintain the existing property access from Eumundi Noosa Road to the developed portion of the lot. This area is
not part of the proposed development site.
The Lot 30 on SP170751 is part of a reconfiguration application for two lots. With a total area of 5019 m2 it is
understood that the lot will be divided in lots of 2448 m2 (Lot 1) and 2571 m2 (Lot 2) with an easement access in
lot 2 in favour of lot 1. The proposed development will be located in Lot 1 with the residual lot (Lot 2) being a vacant
lot.
A geotechnical investigation will be completed to determine soil type and any specific treatment or management
requirements to mitigate erosion or pollution of the environment. This will be developed at the Operational Works
stage of the development. A location of the site is shown on Figure 1.

3 SITE TOPOGRAPHY AND EXISTING DRAINAGE
Refer to Appendix B for the survey plans provided by John Dawson Surveys Pty Ltd dated 10th September 2015,
which shows the existing condition of the site. The development site has existing surface levels approximately
between RL 9.33 and 12.20 m AHD. The development site has only one catchment of varying slope. The site
generally falls from the North-East to the South-West. The legal point of discharge are gully pits located on
Eumundi Noosa Road and Walter Hay Drive.
Currently the majority of the site does not discharge to a lawful point of discharge, most of the stormwater runoff
flows unmitigated to Eumundi Noosa Road and Walter Hay Drive. Refer to Appendix D for the pre-development
catchment plan scenario. The existing catchment boundary has been maintained in the post development
scenario but the stormwater runoff conveyed, mitigated and discharged to the legal point of discharge. Refer to
Appendix E for a Conceptual Stormwater Management Plan for the proposed development.

4 FLOODING
A Storm tide Information Map (Map 10-D34) obtained from the Noosa Council website states that the site is outside
the known floodplain extent. Refer to Appendix C for the Noosa Council’s Stormtide Information Map 10-D34 –
September 2012. A close up of the Map showing the development site highlighted is shown in Figure 2 below.
Figure 2: Close up of the Stormtide Information Map 10-D34 showing the development site (in red)
5 PROPOSED DRAINAGE LAYOUT
The post development stormwater drainage design generally maintains the overall catchment boundary, the design
separates the high risk (hydrocarbon generating e.g. under the canopy) area from the low risk areas (the rest of
the site). Any spillage or minor spills from under the canopy will be captured by grated gully pits and directed to a
Spel® Puraceptor for hydrocarbon removal, which then discharges to the stormwater network. The fuel delivery fill
point (unloading area) will be located under the canopy and any spills that might occur during unloading will be
directed to the Spel® Puraceptor. A licensed contractor will remove the contents of the Puraceptor when required.
Stormwater runoff generated from low risk areas (the rest of the site) will be captured and conveyed by gully pits
and underground pipes, which then discharge to the legal point of discharge on Eumundi Noosa Road. All the
stormwater runoff generated from low risk areas on the site will be treated using Spel® Stormsacks. Refer to
Appendix E for a concept plan of the stormwater drainage and site grading.

TfA Project Group Pty Ltd Stormwater Management Plan
Development Application
Overland run-off from the undeveloped upstream catchment area will be conveyed via spoon drains and gully pits
installed along the top of a proposed retaining wall located on the Eastern boundary of the proposed development
discharging to the legal point of discharge on Eumundi Noosa Road. Details of the spoon drain and pit locations,
as well as hydraulic calculations, will take place in the detail design stage of the development.
6 WATER QUANTITY ASSESSMENT
The purpose of this part of the assessment is to investigate whether there is a need to attenuate stormwater flows
to negate any adverse impacts on upstream or downstream environments. Stormwater runoff from both pre and
post-development scenarios will be calculated and the results analysed and possible solutions proposed.
6.1 Catchment Analysis
The total proposed development area is 2,448m² (0.248 Ha). Details of the pre-development catchment are
shown in Table 2 below, which shows the surface types, areas, percentage imperviousness and fraction
impervious.
Table 2: Pre-development catchment characteristics
Surface Type Area (m²) Percentage Imperviousness Fraction impervious
Roof and Paved 0 100
Area 0.00
Landscaped Area 2,448 0
Details of the post-development catchment are shown in Table 3 below, which shows the surface types, areas,
percentage imperviousness and fraction impervious.
Table 3:Post-development catchment characteristics
Surface Type Area (m²) Percentage Imperviousness Fraction impervious
Roof and Paved 1,673 100
Area 0.68
Landscaped Area 775 0
Tables 2 and 3 above show that the fraction impervious for the post-development case is higher than the fraction
impervious of the pre-development case, this will result in increased peak flows in the post-development case
therefore onsite stormwater detention is required.
6.2 Stormwater Detention Sizing
6.2.1 Rational Method
The rational method was used to calculate the stormwater runoff flows from the site for the pre and post-
development scenarios. The formula is as follows:
Qy = (2.78 * 10-3)) Cy*A* tIy (QUDM 2007 Equation 4.02)
123 Eumundi Road (Cnr Walter Hay Drive), Noosaville QLD 4566 Page 4
Section 11
TfA Project Group Pty Ltd Stormwater Management Plan
Development Application
Where:
Qy = peak flow rate (m3/s) for average recurrence interval (ARI) of ‘y’ years
Cy = coefficient of discharge (dimensionless) for ARI of ‘y’ years
A = area of catchment (ha)
tIy = average rainfall intensity (mm/h) for a design duration of ‘t’ hours and an ARI of ‘y’ years.
t = the nominal design storm duration as defined by the time of concentration (tc).
The value of 2.78 x 10-3 (or 1/360) is a conversion factor to suit the units used.
6.2.2 Catchments
The existing catchment boundary has been maintained in the post development scenario. Pre and post-
development catchment information is tabulated in Table 4 below.
Table 4: Catchment details
Pre-development Pre-development Post-development Post-development
Area (Ha) fraction impervious Area (Ha) fraction impervious
0.24 0.0 0.24 0.68
6.2.3 Time of concentration
The time of concentration of the pre-development scenario was calculated using the Friend’s equation for
overland sheet flow and figure 4.09 and 4.10 of the Queensland Urban Drainage Manual (QUDM 2007). The
equation is shown below:
tc = (107.n .L0.333) / S0.2 (QUDM 2007: Equation 4.06)
Where:
tc = overland sheet flow travel time (min)
L = overland sheet flow path length (m)
S = slope of surface (%)
The value ‘107’ is a conversion factor to suit the units used.
The time of concentration for post-development scenarios was determined using the above equation 4.06 with a
minimum of 6 minutes as instructed in the Planning Scheme Policy 5 - Noosa Council. Table 5 below shows the
times of concentration used in the water quantity assessment.
Table 5: Times of concentration for the catchment
Catchment Time of concentration
Pre-development 10.00
Post-development 6.00
6.2.4 Coefficient of Discharge
From Table 4.05.3(a) and 4.05(b)of QUDM, a one hour rainfall intensity for a 1 in 10 year ARI (1I10) of 72.3 mm/hr
and fraction impervious fi of 0.0 has a C10 value for the pre-development catchment of 0.70. The post-
development C10 value is 0.84. Table 6 below shows the Fy factor used to calculate the Cy value for each ARI.

Fy 0.80 0.85 0.95 1.00 1.05 1.15 1.20
The coefficient of discharge for both pre and post-development catchments is calculated based on equation 4.05
of QUDM and the results shown in Table 7.
Table 7: Coefficients of discharge for pre and post-development scenarios

Post-development Catchment 0.67 0.71 0.80 0.84 0.88 0.97 1.01
6.2.5 Rainfall Intensities
The rainfall intensities for the site were read from an IFD table obtained from the BOM website for the project site
on 25 September 2015. The rainfall intensities for a given time of concentration for the pre and post-development
cases for the nominated ARI’s are shown in Tables 8 and 9.

As can be seen from Table 12 below, the development will increase stormwater runoff for the catchment for the
nominated ARI’s, therefore onsite stormwater detention will be required to mitigate the peak discharge and achieve
the “no worsening” of the stormwater drainage conditions external to the site.
Table 12: Stormwater flow differences between post and pre-development for standard ARI’s

Stormwater runoff from the back of the proposed building at the Southern area (390 m2) of the site will flow
unmitigated by passing detention. A gully pit will convey the runoff and will discharge the flow to the legal point of
discharge on Walter Hay Drive. Table 13 shows the stormwater flow generated by the bypassing area.

6.2.7 Required Detention Volume
The onsite detention volume will restrict the post-development flows to pre–development levels. The required
detention volumes were estimated using the equation 5.04 (After Basha 1994), outlined in Section 5.05.1 of
QUDM (2007). Table 15 shows post-development flow rates, allowable discharges from the detention basin(s),
and the detention storage volume required to achieve the “no-worsening” of the drainage conditions external to
the development site for the nominated ARI’s.

*The figures are based on the stormwater runoff from the pre-development catchment less the stormwater runoff
from the non-developed area at the back of the proposed building on the Southern corner of the post-development
catchment.
Therefore, a 38,400L detention storage volume is required to mitigate peak flows from the catchment. The outlet
arrangement of the detention basin shall be designed at the Operational Works phase of the project and it will
ensure that the design flow rates do not exceed pre-development flow rates for the nominated design storm events.
Appropriate design software shall be used at the operational works stage to determine the actual design volume
of the onsite detention basin required and a suitable outlet arrangement (e.g. orifice plate, culvert, etc.).

7.2.2 Water Quality Objectives
The total area of the site being developed is less than 2,500m² therefore the development is not required to
achieve the TN, TP and TSS pollutant reductions outlined in the Queensland State Planning Policy (SPP) July
2014.
7.2.3 Stormwater Treatment Philosophy
Waterways and other aquatic environments are valued by the community for their social, cultural, economic and
environmental benefits. Urban runoff, contaminated with nutrients, sediment and other pollutants adversely
impacts theses valued resources. Water Sensitive Urban Design (WSUD) is a holistic approach to the planning
and design of urban landscapes that minimises theses negative impacts. This approach is used on this project to
select the treatment options that considers the civil, landscape and ecological aspects of the site.
7.2.4 Source Controls
Rubbish bins can be an effective source control for litter and are appropriate for most developments. Bins will be
placed in appropriate areas (such as buildings and staff amenity) to encourage thoughtful waste disposal.

7.2.5 Gross Pollutant Traps
A GPT is a treatment device designed to capture coarse sediment, trash and vegetation matter in stormwater
runoff. GPTs are often used as the first treatment element in a treatment train. Spel® Stormsacks or a similar
approved product will be used within this development; the Stormsacks will be installed in gully pits, refer to
Appendix F for typical details.
7.3 Fuel Related Stormwater Treatment
The treatment train shown in Figure 3 uses the Best Management guidelines to treat stormwater runoff from the
site.

7.3.1 Fuel Dispensing Areas
The fuel dispensing area will be concrete surfaced and covered by a canopy. The fuel dispensing area will be
bunded to prevent stormwater runoff from outside the canopy flowing into the dispensing area and to ensure that
any spills are contained within this area. The perimeter of the canopy will overhang the dispensing containment
area by 10 degrees to reduce the amount of windblown rain into the dispensing area. Any flows/spills in the
containment area will drain to gully pits which will discharge to an appropriately sized Spel® Puraceptor.
Bulk fuel transfers from a road tanker to underground tanks will take place under the canopy; any runoff from the
dispensing area will be directed to a Spel® Puraceptor. A spill containment box at fill points will capture any minor
fuel spills that may occur during unloading; the spilt fuel will then drain from the containment box into the fuel
storage tanks.

7.3.1.1 Spel® Puraceptor
The Puraceptor will have a minimum containment volume of 10,000litres, which allows for containment for spill
from an 8,000 litre tanker compartment plus allowances for wind-blown rain. The Puraceptor will remove
hydrocarbons, gross pollutants and total suspended solids. Refer to Appendix F for details of the Spel® Puraceptor.
7.3.2 Underground Fuel Storage Tanks
Underground fuel storage tanks, piping and fuel dispensers will be installed in accordance with the Australian
Institute of Petroleum (AIP) standards.
7.3.3 Areas outside Canopy
All driveways and car parking areas will be concrete surfaced and will drain via gully inlet pits, which will have
Spel® Stormsacks inserts to capture gross pollutants before discharging to the legal point of discharge. Refer to
Appendix F for typical details of the Stormsacks system.
7.4 Water Quality Assessment
No water quality assessment is required as the total site area is less than 2,500m².
8 SITE MAINTENANCE AND MANAGEMENT PROCEDURES
The service station operator will have a Petrol Handling Manual that will set out all requirements for the safe
handling of combustible and flammable materials. This manual will dictate weekly, monthly and annual checking
procedures with checklists, which will be completed, and the records stored.
The manual will also set out dry cleaning methods to be employed within the fuel dispensing area in lieu of washing
down to reduce possible contaminated runoff. Emergency procedures will be also clearly set out detailing actions
to be taken by site personnel in the case of varying possible emergencies such as spills, fire or risk of fire, vehicle
accidents, etc.
In addition a regular cleaning, maintenance program/contract is to be established for emptying of rubbish bins
located around the site, removal of general litter from the site, inspection of stormwater gully pits and removal of
any sediment or captured litter from the Spel® Stormsacks systems. The Spel® Stormsacks will be inspected and
maintained in accordance with the manufacturer’s instructions. Refer to Appendix G for maintenance plans.
The maintenance plan will address the following:
• Inspection frequency;
• Maintenance frequency;
• Data collection/storage requirements;
• Detailed cleanout procedures.
The plan will include inspection procedures covering aspects such as equipment needs, maintenance techniques,
occupational health and safety, public safety, environmental management considerations, disposal requirements
of pollutants collected and access issues.

8.1 Maintenance Plans for Stormwater treatment devices
All stormwater quality improvement systems require regular maintenance in order to function adequately. Table 18
details the basic maintenance requirements for each type of stormwater quality improvements systems. A detailed
maintenance schedule will be developed as part of the detailed design of the site.
Table 20: Maintenance Requirements
Control Maintenance Requirement Maintenance Period
Spel® Remove sediment and captured litter 4 months (inspect after
Stormsacks
major storms)
Spel® Puraceptor Replacement of oil separators and coalescer units, removal of 6 Months (inspect after
oil, sediment & gross pollutants (skimmers and vacuum truck) major spill)
Onsite Detention Removal of accumulated sediment, debris 6 Months (inspect after
Basin major storms)
For operational and maintenance guidelines refer to Appendix G and relevant manufacturer’s documentation.
9 LIFECYCLE COSTS
A lifecycle cost analysis is not part of the scope of this report. All the recommended water quality treatment
infrastructure lies within the development site and it shall be maintained and serviced by the owners of the
development at no cost to Council.
10 CONCLUSION
A Site Based Stormwater Management Plan has been prepared with respect to the proposed service station and
retail. The location of the site is shown on Figure 1 and the proposed development site layout is shown in
Appendix A.
• Stormwater Quantity
An assessment of the water quantity has resulted in an onsite detention basin size of 38,400L with
controlled outlet to mitigate the peak discharge and achieve “no worsening” of stormwater conditions
external to the site. The detention storage volume is based on preliminary calculations; the actual
detention storage volume required and outlet arrangement will be determined by appropriate software
as outline in section 5.05.2 of QUDM (2007).
• Stormwater Quality- Construction Phase
An Erosion and Sediment Control Plan aimed at minimising unacceptable impacts during the
construction phase will be developed at the Operational Works stage, in accordance with Noosa Council
Guidelines and Standards.
• Stormwater Quality- Operational Phase
It is proposed to treat runoff from the surface of the site by using Spel® Stormsacks or similar approved
devices. The location of proposed treatment measures is shown in Appendix E.

SPEL AUTO CLOSURE DEVICE (ACD)
• SPEL ACDThe Automatic Closure Device (ACD) is found in the first chamber of a PuraceptorTM. The purpose of
the ACD is to close the separator off automatically when the maximum storage capacity of light liquid is attained.
The ACD is to ensure that in the event of a major spillage, pollutants do not pass into the drainage system; it
should not be regarded as a substitute for an automatic alarm / monitoring system.
Prior to installation
Prior to installation the ACD retaining tube should be covered to prevent ingress of concrete etc., which could fall onto the ACD and
upset it’s calibration.
Operation and Maintenance
If the tank should fill with light liquid, the ACD which is calibrated for a specific gravity of 0.85, will automatically sink and
close off the SPEL PuraceptorTM.
Normally routine maintenance would include removing light liquid intercepted within the PuraceptorTM. If a SPEL automatic alarm / monitoring
system is incorporated, it will automatically indicate when the PuraceptorTM should be emptied. Only in an emergency will the PuraceptorTM fill to
it’s maximum and operate the ACD.
In such an event the PuraceptorTM should be completely sucked out and the ACD lifted out. Check that the ACD is in good working condition – ie.
Lifting hook secure and sealed; float not leaking; knuckle joint free and clean; sealing ring intact and complete. Clean with warm soapy water
before re-inserting.
To re-insert the ACD, partially fill the PuraceptorTM with clean water (if necessary) to ensure the ACD when re-inserted remains floating.
Re-insert the ACD.
Finally check the ACD is floating and the retaining cap has been replaced to
safeguard against it’s removal by unauthorised persons, unless depth of tank
precludes doing so from ground level.

SPEL Automatic Alarm/Monitoring System
The SPEL automatic alarm/monitoring system provides a audible warning alarm when the level of the oil in the SPEL separator reaches
approximately 10% of the storage volume under static liquid level conditions. This is a early warning system that is used for spills
or lack of maintenance.
The system comprises of a probe mounted in the main separation chamber which senses when the designed volume of light liquids has
accumulated and sends a signal to the electronic control unit activating a red ‘empty now’ warning light and an audible alarm,
Safe area Operation
Hazardous area Control The probe is freely suspended in the probe protection tube in
SPEL seperator Unit the separator at the correct level. When the oil-layer or depth
of hydrocarbons reaches the predetermined level, the top of
the probe will be immersed in the oil, breaking the circuit and
activating the alarm. It is a ‘fail-safe’ system providing
complete assurance that it is operative. If a fault occurs it will be
signalled immediately.
Installation
Control unit (general positioning)
The control unit has been designed to be located indoors and
outdoors, within a nonhazardous area. It should be wall mounted
and positioned such that the LED display and push switches
on the front panel can be readily seen and accessed. The unit
can be secured to the wall by using the four mounting holes
provided. Included within the control is an intrinsically safe
circuit (approved according to ATEX Directive 94/9/EC), to
which the probe unit is connected.

Certificate of conformity
The alarm device has been approved to be used in explosion-hazardous areas. The
control unit and probe are approved according to ATEX Directive 94/9/EC. These
approvals mean that the probes can be installed in Zone 0, which is continuously
explosion-hazardous.
The SPEL oilset control unit must be located in the safe area, but it can be
connected to the probe without any barrier.
Tests (10.2)
The function can be tested by lifting the probe within the probe protection tube. In
approximately 5 seconds, the alarm is given by a red light and audible signal. Both
relays release. Push the RESET button - the buzzer goes off and relay pulls in.
When the probe is placed in water again, relay pulls in and the red light goes off.
Cable break and short circuit test
Also the function can be tested in case of cable fault or short circuit. First cause
short circuit in probe cable terminals 1 and 2. Then the yellow light of short circuit
is lit. Both the relays pick up and the buzzer goes on. Remove the short circuit and
reset the buzzer.
Simulated Function Test
The function of probe, cable and electronics can be tested. Push the TEST button for
2 to 5 seconds. Both relays pick up, and the red light is lit. When the TEST button is
released, the red light goes off and relay returns to its normal position. The buzzer
and relay must be reset.

Installation and Operating Instructions
1 GENERAL
OilSET-1000 is an alarm device for monitoring the thickness of the oil
layer accumulating in an oil separator. Depending on the order, the
delivery consists of OilSET-1000 control unit, SET/DM3D probe and a
cable joint.
Figure 1. Oil separator alarm system
SET/DM3D probe is installed into the light liquid storage chamber and
gives an alarm when the chamber is filled to a pre-determined degree.
The probe is normally immersed in water.
The function is based on the measurement of the electrical
conductivity of the surrounding liquid – water conducts electricity
much better than oil.
Oil separator is regarded as potentially explosive (Ex) area.

Installation and Operating Instructions
2.2 SET/DM3D probe
SET/DM3D probe should be installed as described in figure 3.
The probe gives an alarm earliest when the upper electrode is in oil
and latest when the probe is totally immersed in a non-conductive
liquid - in other words, it is totally away from the water.
Please check the correct installation depth also from the instructions
of the oil separator.
2.3 Cable joint
Fig. 4 Cable joint SK-3-2500
Connections of the probe cable inside the cable joint are explained in
figure 3. Cable shields and possible excess wires need to be
connected to the same point in galvanic contact.
Please make sure, that the probe and cable between OilSET-1000
control unit and the probe do not exceed the maximum allowed
electrical parameters – see chapter 7 Technical data.
IP rating of the cable joint is IP67. Make sure, that the cable joint is
closed properly.
If the probe cable must be extended and there is a need for
equipotential grounding, it should be done with the junction box LJB2.
The cabling between the OilSET-1000 control unit and the junction
box should be done with a shielded twisted pair instrument cable.

Oil Alarm LED indicator remains on.
Buzzer remains on. If it has been reset earlier, it will return to be on.
If relay 1 was already reset, it will de-energize again after 2 sec. of
continuous pressing.
Test will not affect relay 2, because it is already in alarm status.
When the Test push button is released:
The device returns without delay to the preceding status.
Fault alarm on When pressing the Test push button:
The device does not react to the test at all.
3.2 Factory settings
If the operation of OilSET-1000 is not as described in the previous
chapter, check that the device settings are as in figure 7. Change the
settings according to the following instructions if needed.
The following tasks must only be executed by a person with proper
education and knowledge of Ex-i devices.
We recommend, that when altering the settings the mains voltage is
off or the device is initialized before the installation is executed.
Figure 7. Factory settings
The settings are made with switches (MODE and DELAY) and
potentiometer (SENSITIVITY) located in the upper printed circuit
board, and the jumper located in the lower board (figure 7). In figure 7,
the switches are as set in the factory.
Switch S2 is used to set the operational delay of the control unit. When the switch is in low
position, relays operate and buzzer is on after 5 seconds after the level has reached the
trigger level, and if the level still remains on the same side of the trigger level.
When the switch is in high position, the delay is 30 seconds.
Delays are operational in both directions (energizing, de-energizing). Alarm LED follows the
probe current value and trigger level without delay. Fault alarm takes place after a fixed delay
of 5 sec.

4 TROUBLE-SHOOTING
Problem: MAINS LED indicator is off
Possible reason: Supply voltage is too low or the fuse is blown. Transformer or MAINS LED
indicator is faulty.
To do: 1. Check if the two pole mains switch is off.
2. Check the fuse.
3. Measure the voltage between poles N and L1. It should be 230 VAC + 10 %.
Problem: No alarm when probe in oil or air, or the alarm will not go off
Possible reason: The SENSITIVITY setting is wrong in the control unit (see figure 7), or probe is
dirty.
To do: 1. Clean-up the probe and lift it up in the air or immerse it into oil.
2. Turn the SENSITIVITY potentiometer slowly anticlockwise until the probe gives
an alarm.
3. Immerse the probe into water and wait until the alarm goes off. If the alarm does
not go off, turn the potentiometer slowly clockwise until the alarm goes off.
4. Lift the probe up in the air or oil. The probe should give an alarm again.
Problem: FAULT LED indicator is on
Possible reason: Current in probe circuit too low (cable break) or too high (cable in short circuit).
The probe might also be broken.
To do: 1. Make sure, that the probe cable has been connected correctly to the OilSET-
1000 control unit. See probe specific instructions.
2. Measure the voltage separately between the poles 10 and 11. The voltages
should be between 10,3….11,8 V.
3. If the voltage is correct, measure the probe current. Do as follows:
3.1 Disconnect probe’s [+] wire from probe connector (pole 10).
3.2 Measure short circuit current between [+] and [-] poles.
3.3 Connect mA-meter as in figure 8.
Make a comparison to the values in Table 1.
3.4 Connect the wire back to the connector.
If the problem can not be solved with the above instructions, please contact
Labkotec Oy’s local distributor or Labkotec Oy’s service.
Attention! If the probe is located in an explosive atmosphere, the multimeter must
be Exi-approved!

[email protected] SAFETY INSTRUCTIONS
OilSET-1000 control unit must not be installed in potentially explosive
atmosphere. Probes connected to it may be installed in zone 0, 1 or 2
potentially explosive atmospheres.
In case of installations in explosive atmospheres the national
requirements and relevant standards as EN 50039 and/or EN 60079-
14 must be taken into account.
If electrostatic discharges can cause hazards in the operating
environment, the device must be connected into equipotential ground
according to requirements with regards to explosive atmospheres.
Equipotential grounding is made by connecting all conductive parts
into same potential e.g. at the cable junction box. Equipotential ground
must be earthed.
The device does not include a mains switch. A two pole mains switch
(250 VAC 1 A), which isolates both lines (L1, N) must be installed in
the main power supply lines in the vicinity of the unit. This switch
facilitates maintenance and service operations and it has to be marked
to identify the unit.
When executing service, inspection and repair in explosive
atmosphere, the rules in standards EN 60079-17 and EN 60079-19
about instructions of Ex-devices must be obeyed.
