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.
Note:
Sensors are activated in a
sequence: Sensor 1 (level sen-
sor WGA-ES4 ) active in 4 sec
-> sensor 2 (thermistor sensor
WGA-R6-S) active in 45 sec ->
sensor 3 (sludge sensor WGA-
ES8) active in 4 sec.This se-
quence is repeated continuously.

Blockage at outlet to separator
(critical alarm)
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.
