13. Troubleshooting
The exterior unit does not work at all:
• Check the exterior unit’s power supply (AC adapter) and the
correct wiring of the exterior unit.
The door opener does not work:
• Check whether the door opener is correctly wired to the ex-
terior unit.
• The switching output for the door opener is potential free. Only
an internal relay is switched here (for contact rating, see chap-
ter Technical Data).
You will therefore need an additional external power supply
for the door opener.
Important!
Never use the AC adapter of the exterior unit to power
the door opener!
The AC adapter is developed exclusively for the exte-
rior unit!
Never apply mains voltage via the potential-free switch-
ing contact! There is a risk of a life-threatening electric
shock!
