15. Troubleshooting
Preprogrammed settings are not affected by a power cut. However, the code lock will be
non-operational during a power cut.
For safety reasons, we recommend that you use an uninterruptible power supply
for the code lock (as in case of an alarm system) depending on the intended use.
The door opener doesn't work
•
The changeover contact is potential-free. This means that you must use the appropriate
external wiring because the code lock does not supplies voltage/power to the door opener.
•
If the door opener has polarity markings (plus/+ and minus/-), ensure that it is connected
to the code lock in the correct polarity.
•
Check the polarity of the protective diode connected to the door opener.
• The used fingerprint or transponder is not tuned-in.
• The changeover contact cannot be activated with the superuser fingerprint or superuser
transponder.
The transponder does not work
•
Always hold only one transponder in front of the code lock, the correct position is below
the fingerprint sensor.
•
The distance between the transponder and the code lock should not exceed 3 cm.
•
Only EM transponders with a frequency of 125 kHz can be used.
•
Metal objects in the vicinity of the code lock or transponder can impair the function of a
transponder (for example, if the transponder is in a wallet together with coins).
• The code lock has been locked with a superuser fingerprint or superuser transponder.
Functional problems associated with the fingerprint sensor
• Keep the glass of the fingerprint sensor clean.
• The detection is based on the different lines (skin ridges) on the fingertip. Therefore, even
thin disposable gloves prevent detection.
