Installation and Operating Instructions
Normal situation When pressing the Test push button:
Oil Alarm and Fault LED indicators are immediately on.
Buzzer is immediately on.
Relays de-energize after 2 sec of continuous pressing.
When the Test push button is released:
LED indicators and buzzer go immediately off.
Relays energize immediately.
Alarm on When pressing the Test push button:
Fault LED indicator is immediately on.
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.
