Troubleshooting
Note:
If an input did not have a sensor
installed when the system was
installed, this will not be scanned.
To activate an inactive output, see
the Maintenance section.

Check
Check the thickness of the oil/grease
layer
Measure voltage at sensor
Blockage at outlet to separator
(critical alarm)
Measure voltage at sensor
The sludge level has reached a set
alarm level (normal alarm)
Measure voltage at sensor
Seperator alarm OSA 3 • Manual
Sensors are activated in a se-
quence: Sensor 1 (level sensor
ES4 ) active in 4 sec -> sensor 2
(thermistor sensor R6-S) active in
45 sec -> sensor 3 (sludge sensor
ES8) active in 4 sec.This se-
quence is repeated continuously.
Cause/action
Order emptying
Error in sensor circuit to sensor (e.g.
cable failure/short-circuit)
Clear blockage or find out cause
Error in sensor circuit to sensor (e.g.
cable failure/short-circuit)
This normally means that the sludge
layer in the tank is too great, this
normally results in impairment of the
efficiency of the separator. Separator
emptying should be ordered.
Error in sensor circuit to sensor (e.g.
cable failure/short-circuit)
