In the event of a fault or a complete failure of the output signal, the gauge can eas-
ily be checked.
• Voltmeter / ohmmeter
• Allen key, AF 2.5
• Spare sensor (if the sensor is faulty)
The output signal is available at the sensor cable connector (Pin 2 and Pin 12).
In case of an error, it may be helpful to just turn off the mains supply and
turn it on again after 5 s.
