Fault Detection - HB Products HBOR Instruction Manual

Fault Detection

General:
NOTE! Fault detection on the electronics and/or replacement of the electronics can be
carried out without releasing pressure on the system or removing the mechanical part of the
sensor
Fault Detection
Fault
No LED is on.
Sensor does not trigger even
though there is oil.
Red alarm
3 x Green blinks
No output (3 x green LED are on,
but the output signal is not

Complaint cases are handled by the HB Products dealers/distributors.
Their complain procedures must be followed before returning the sensor.

Fault in the electronics
Correction of fault
Check and find faults in the power
supply. Change the supply cable.
Recalibrate the sensor.
Check system oil return. Check oil
filter and magnetic valve if
necessary.
Change "prel delay" to a higher
value.
Change the setup using the tool.
Check if the sensor is placed
optimally.
Send the sensor to be repaired.
