Door Coding System
430 - 10
External noise influences - reset key
Despite internal proofing measures exceptionally strong
noise fields can bring about a malfunction
microprocessor-controlled door coding system. Noise
influences can be prevented if the following points are heeded
during installation:
– Do not mount the unit in the immediate vicinity of
inductive power consumers.
– Lay a separate line for mains voltage supply
(possibly using a mains filter) .
– Suppress any inductive power consumers
(varistors, RC-sections).
After elimination of the noise, resetting of the door coding
system is necessary. For this purpose the reset key, which
is located on the main board, has to be pressed until the
adjacent yellow LED illuminates briefly.
