11. Troubleshooting
Problem
Possible Causes
Ready
LED is Off
Auxiliary voltage supply has failed
(Unit
Not
Ready)
Actuator is not connected correctly or is defective
Position sensors are not connected correctly or are defective
Auxiliary voltage is interrupted and the capacitor charge has fallen below the
O-CO criterion
Push button panel is not connected correctly or is defective
The number of maximum permitted "unsuccessful" switching operations is
reached. As a result the apparatus is blocked.
Actuator coil is defective
Apparatus position in discordance
Active signals from Remote system
Ready
LED flashing
Apparatus is in the ON position and the closing coil of the actuator is
defective or not connected correctly
Auxiliary voltage supply has failed
During startup of the apparatus or after switching sequences during the
capacitor charging operation
A close operation
Actuator closing coil is defective
is not executed
ON Signal present
Input Y6 is open
Capacitors are not connected
Ready
Push button panel is not connected correctly or is defective
Only for Version APPL.0: No switching possible from the push button panel
Only for Version APPL.0: No operation possible by the remote control
Energy in the capacitors is too low for a CO operation
No remote control is possible
An O operation is

Capacitors are not connected
Remote signals for opening are not given
Setting of Jumper JP1001 with function and input BI Y4 are not correct
Undervoltage monitoring is not activated
Push button panel is not connected correctly or is defective
Apparatus closes and
Position sensor for ON position is not connected correctly or is defective

Possible Remedies
Restore auxiliary voltage
Check plug and continuity check of the coils
Check connector and check operation with a metal ruler (change of LED
indicators)
Restore auxiliary voltage
Check connector or exchange component
Disconnect auxiliary voltage, COMPLETELY discharge capacitors so that
the function performs a counter reset.
General check of the apparatus
Disconnect auxiliary voltage, COMPLETELY discharge capacitors. Then
check actuator coils
Movement is obstructed by object. Try to open by hand crank
Check the remote control unit
Only OFF cycle is possible. Open apparatus (Ready LED goes out) and
check defective actuator coil.
In the ON position, the apparatus can still be switched OFF.
In the OFF position, a CO switching sequence can be executed.
Restore auxiliary voltage
Normal behaviour, wait for several seconds (charging time 1 to 3 min.)
Check actuator closing coil
Check status of all input signals
Close contact
Check the connection plug and capacitor cable
See points
"Ready
LED flashing"
Check plug or exchange component
Check the Dip Switch I1004-5 configuration and the position of the
LOCAL/REMOTE selector switch (if fitted)
Check the Dip Switch I1004-5 configuration and the position of the
LOCAL/REMOTE or GLOBAL selector switch (if fitted)
Restore auxiliary voltage.

Check all external connections
Check actuator opening coil
Check the connection plug and capacitor cable
Check the connections of the signal cable
Check the correct Jumper setting. With a PR5xy device, JP1001 must be
in position 1+2.
Correct setting of the undervoltage threshold and delay with dip switch
I1001 and I1004
Check plug or exchange component
Check connector and check operation with a metal ruler (change of LED
indicators)
Check whether foreign bodies obstruct movement.
Status check of the drive mechanism
Check the voltage (80V) and change components if necessary
Connect undervoltage signal input with a different power supply
If possible, deactivate function with dip-switch I1004
Restore auxiliary voltage
Check the connection plug and capacitor cables
Contact ABB
Close signal input and repeat procedure
To obtain a "re-close" after a normal ON switching action, the ON signal
must be cancelled and reactivated.
After every "Reclose" function, the ON signal must be cancelled. For a
series of repeat functions, the ON signal must be cancelled and
reactivated
Remove those jumpers not described and perform restart after
complete discharge of the capacitors
Disconnect auxiliary voltage supply and discharge capacitors
completely. After a restart, the new setting is activated.
