Installation and Operating Instructions
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!
SET/DM3D, channel 1
Poles 10 [+] ja 11 [-]
