Hva betyr feilkoden?
The upper electronic module (UEM) has lost contact with the movement sensor. The code is set on a communication fault, which can come from a poor contact at the sensor or on the module side, a break in the sensor's voltage supply, or a faulty sensor. The alarm then does not respond to the sensor.
Mulige årsaker
- Poor contact on the sensor side and/or on the control module side
- Open circuit in the movement sensor's voltage supply
- Faulty sensor
Hva du kan gjøre
- 1Read off the code, clear it and check whether it returns.
- 2Look for loose connectors, corrosion and damage at the sensor and at the upper electronic module.
- 3Use a multimeter to check that the supply wire to the sensor is not broken.
- 4Check that both connectors are firmly seated and not oxidised.
- 5If no fault is found, have a workshop replace the sensor.
