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 sensor 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 sensor is 
dirty. 

To do: 

1. Clean-up the sensor and lift it up in the air or immerse it into oil. 

 

2. Turn the SENSITIVITY potentiometer slowly anticlockwise until the sensor gives 
an alarm. 

 

3. Immerse the sensor 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 sensor up in the air or oil. The sensor should give an alarm again. 

 

 

Problem: 

FAULT LED indicator is on 

Possible reason: 

Current in sensor circuit too low (cable break) or too high (cable in short circuit). 
The sensor might also be broken. 

To do: 

1. Make sure, that the sensor cable has been connected correctly to the OilSET-
1000 control unit. See sensor 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 sensor current. Do as follows: 

 

   3.1   Disconnect sensor

’s [+] wire from sensor 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 sensor is located in an explosive atmosphere, the multimeter must 
be Exi-approved!
