Problem Solving
Condition
Problem solution – Try with the solutions listed in the order described
COND.04
1)
Make sure the actuator inserted is the correct one. The actuator-device coupling is univocal
2)
Couple the actuator if not coupled yet
3)
Replace the key and repeat the procedure
4)
Replace the device and/or contact the technical support if the problem persists
COND.05
COND.06
1)
Check the actuator is still present, mechanically intact and correctly positioned
2)
Replace the key and couple again
3)
Replace the device and/or contact the technical support if the problem persists
COND.09
COND.10
COND.11
1)
Restore the correct device supply
2)
Replace the device if the problem persists
COND.08
COND.12
1)
Restore the correct device supply
2)
Replace the device if the problem persists
NOTE if the problem is solved after point 1, check the device has not been damaged during the maintenance cycle
