Problem Possible Causes Possible Remedies
Ready LED is Off Auxiliary voltage supply has failed Restore auxiliary voltage
(Unit Not Ready) Actuator is not connected correctly or is defective Check plug and continuity check of the coils
Position sensors are not connected correctly or are defective

Restore auxiliary voltage
Push button panel is not connected correctly or is defective Check connector or exchange component
reached. As a result the apparatus is blocked.
Disconnect auxiliary voltage, COMPLETELY discharge capacitors so that
the function performs a counter reset.
General check of the apparatus
Actuator coil is defective Disconnect auxiliary voltage, COMPLETELY discharge capacitors. Then
check actuator coils
Apparatus position in discordance
Active signals from Remote system Check the remote control unit
Ready LED flashing Apparatus is in the ON position and the closing coil of the actuator is
defective or not connected correctly
check defective actuator coil.
Auxiliary voltage supply has failed
Restore auxiliary voltage
capacitor charging operation
A close operation
is not executed
Actuator closing coil is defective Check actuator closing coil
ON Signal present Check status of all input signals
Close contact
Capacitors are not connected Check the connection plug and capacitor cable
Ready LED on the push button panel is off See points “Ready LED flashing”
Push button panel is not connected correctly or is defective Check plug or exchange component
Restore auxiliary voltage.
See points “Ready LED flashing”
No remote control is possible Check all external connections
An O operation is
not executed
Actuator opening coil is defective Check actuator opening coil
Capacitors are not connected Check the connection plug and capacitor cable
Remote signals for opening are not given Check the connections of the signal cable
Undervoltage monitoring is not activated
Push button panel is not connected correctly or is defective Check plug or exchange component
Apparatus closes and
opens automatically
Position sensor for ON position is not connected correctly or is defective
