Firmware update
The firmware can be updated at the control panel with WINFEM Advanced via BUS-2.
With an update via BUS-2, a tamper signal may be transmitted to the control panel, as
the module activates a reset after the update.
Note:
Error
RS-485 User(s) do not
function
Bolt switching contact
does not function
Module sabotage
No AC function
EU sporadically looses
data carrier authorization
Possible cause
User do not yet have an RS-485
address
End-of-line resistors on RS-485
bus not active
Current drain too high on
connection U_BDT. Current
limitation is activated at approx.
200 mA.
BSC input is LOW active,
therefore no terminating resistors
(0 Ohm)
"Cover contact ext. reader"
connection is not used
DCM outputs not programmed as
no-load current door opener /
strike with load current function
No door opener time programmed
Faults due to external influence
Remedy
Activate address assigning mode
Check JP15 plug-in bridge and
provide terminating resistors in
front of the readers at each end of
the bus line if necessary
Supply consumers via U_ext.
Check
resistor and
remove existing 12k1 if necessary
Terminate input with 12k1
Correct programming
Connection between door strike
operating voltage and 0V of BUS-2?
See note in Point 8.5 to rectify.
Equip DC door strike with a free-
running diode
