7.1 Mechanical Service
7.1.1 Checking Tooth Belt Tension
- The tooth belt must not lift up from the motor gear or skip when braking and accelerating.
- If the tooth belt lifts up or skips, adjust the tooth belt tension to 300 N ± 35 N.
7.1.2 Tensioning the Tooth Belt
See chapter 5.6.4.
7.2 Maintenance
Caution!
Danger of injury due to impact and crushing!
- Secure door leaves against accidental movement.
- Disconnect rechargeable battery.
- Disconnect mains voltage.
- Only genuine spare parts may be used.
- To ensure the functional ability, the wear parts of the sliding door system must be checked at every maintenance and replaced if necessary.
- The prescribed maintenance work on the sliding door system must be done by an expert:
- at least once a year or
- when the service indicator on the programme switch lights up (see wiring diagram).
- Depending on the configuration, not all the wear parts listed are present.
- Provide test documents and keep them up-to-date.

8 Troubleshooting
Warning!
Risk of fatal injury due to electric shock!
- The electrical system (230 V/115 V) may only be connected and disconnected by a qualified electrician or a qualified electrician for specified tasks.
- Carry out mains connection and earth conductor test in accordance with VDE 0100 Part 600.
Caution!
Danger of injury with opened drive! Hair, clothing, cables, etc. can be drawn in by rotating parts.
- Watch out for rotating parts during work on the opened drive.
Caution!
Danger of injury due to impact and crushing!
- Secure door leaves against accidental movement.
- Disconnect rechargeable battery.
8.1 Mechanical Faults
| Cause | Remedy |
|---|---|
| Track bent | Replace the track. Check the installation surface. |
| Moving leaf stiff | Check the moving leaf (see Chapter 8.1.1). |
| Roller carriage jammed or defective, high abrasion on the track rollers | Replace the track roller (see Chapter 8.2), clean the track. |
| Tooth belt damaged | Replace the tooth belt. |
8.1.1 Check Moving Leaf
- Disconnect the moving leaf from the tooth belt using the toothed belt locking.
- Move the moving leaf and check for ease of movement.
- If moving leaves move easily: Check the motor gear unit and deflection pulley and replace if necessary.
8.2 Replacing Roller Carriage
- Loosen the driver from the toothed belt locking.
- Separate the driver from the roller carriage.
- Use the moving leaf installation aid (1) to secure the roller carriage against tilting.
- Loosen the suspension bolts (2) on the roller carriage.
- Take the moving leaf out.
- Undo the hexagon screw (3) on the counter-roller.
- Remove the moving leaf installation aid (1) and replace the track roller or roller carriage.
- Reinstall the roller carriage in the reverse order. Torque suspension bolts (2): 10 Nm.
8.3 Replace Brushes on the Roller Carriage
- If necessary, remove the roller carriage (see Chapter 8.2).
- Pull brushes (2) out of roller carriage.
- Clean the rollers (1) of the roller carriage and insert new brush (2).
- Reinstall roller carriage in reverse order.
8.4 Electrical Faults
For read-out instructions and a list of fault messages, see wiring diagram.
8.4.1 Replacing Fuse in Transformer
Danger!
Risk of fatal injury due to electric shock!
If the main switch on the transformer is activated, the fuse is still energised since it is upstream of the main switch. The mains voltage 230/115 V must be disconnected from the mains upstream of the fuse.
- Disconnect the door system from the 230/115 V mains supply on site before removing the PCB cover (1) and secure against being switched back on again.
- You will find the fuse value on the wiring diagram.
- Insert a suitable screwdriver into the opening of the PCB cover (1) above the switch.
- Carefully press the end wall of the PCB cover upward with the tip of the screwdriver. This releases the snap catch.
- Remove the PCB cover (1).
- Pull the fuse holder forwards and off and replace the defective fuse.
- Attach the fuse holder.
- Do not trap the cable when setting the cover in place.
- Set the PCB cover (1) in place and clip on.
