5. No Mains Voltage
If the mains voltage fails (e.g., due to a power failure), first check the on-site safety fuse to ensure the issue is not local.
5.1 Door behaviour in case of power failure
| State | Reaction |
|---|---|
|
No mains voltage (e.g. power failure) |
In the “Night/Locked” mode of operation, the door is closed and locked. |
| Standard drives | In the modes of operation “Exit only”, “Automatic”, and “Hold open”, the behaviour of the door depends on the parameters set during commissioning:
With drives with built-in rechargeable battery, depending on the function selected:
|
| FR drives |
|
| BO drives |
|
|
No active power supply (SL-T30 and SL-RD) |
Door is closed with reduced closing speed in all the modes of operation. |
| Mains voltage available again | The door automatically returns to the last selected mode of operation. |
|
Power supply available again (SL-T30) |
The door automatically returns to the last selected mode of operation when the reset switch is pressed. The reset switch can be reached by opening the drive cover. |
|
Power supply available again (SL-RD) |
The door returns to the last selected mode of operation as follows:

5.2 Locking/unlocking if there is no mains voltage
| Locking Type | Measures |
|---|---|
| Toothed belt locking |
Locking only makes sense when the door is closed. Locking with drives with built-in rechargeable batteryIf the door is to be locked and this door is the only point of access:
DPS or TPS indicates Night/Locked mode of operation. Unlocking from the outside with drives with built-in rechargeable battery
Sequence: Door opens – door closes – locks again and switches off. Unlocking from the inside with drives with built-in rechargeable battery
Sequence: Door opens – door closes – locks again and switches off. Unlocking with drives without built-in rechargeable battery (only possible from the inside)
The door leaves are unlocked and can be opened manually. |
| Rod locking, Lock A and folding door lock |
Locking is only possible when the door is closed. Locking with drives with built-in rechargeable batteryIf the door is to be locked and this door is the only point of access:
For sliding door with rod locking:
For sliding doors with Lock A (see also installation instructions “Automatic hook bolt lock Lock A”):
With folding door and folding door locking:
DPS or TPS indicates Night/Locked mode of operation. Unlocking from the outside with drives with built-in rechargeable battery
Sequence: Door opens – door closes – locks again and switches off. Unlocking from the inside with drives with built-in rechargeable battery
Sequence: Door opens – door closes – locks again and switches off. Unlocking with drives without built-in rechargeable battery (only possible from the inside)For sliding door with rod locking:
Sliding door with Lock A:
With folding door and folding door locking:
|
| Locking for SL-BO |
Locking is only possible at a closed door. Locking with drives with built-in rechargeable batteryIf the door is to be locked and this door is the only point of access:
DPS or TPS indicates Night/Locked mode of operation. Unlocking from the outside with drives with built-in rechargeable battery
Sequence: Door opens – door closes – door locks again and switches off. Unlocking from the inside with drives with built-in rechargeable battery
Unlocking with drives without built-in rechargeable battery (only possible from the inside)
The door leaves are unlocked and can be opened manually. |
Note: After the mains voltage has been restored, the (locked) door automatically switches to the “Night/Locked” mode of operation.
