Troubleshooting

Error
RS-485 user(s) do not
function
RS-485 reader – no
arming possible
Bolt switching contact
does not function
IK3 EU sabotage
No positive drive
condition when arming or
interval buzzer on EU
Blocking element does
not function
No AC function
EU sporadically looses
data carrier authorization

Mounting accessories

032215.17 IDENTLOC flush mounting kit
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.
Reader programmed as internal
reader
BSC input is LOW active,
therefore no terminating resistors
(0 Ohm)
"Cover contact ext. reader"
connection is not used
Blocking element feedback
signals are incorrect or not
connected, or supply voltage is
too low
JP14 plug-in bridge is inserted
incorrectly
Incorrect wires
EU 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 EOL resistors in front of
the users at each end of the bus
line if necessary
Supply consumers via U_ext.
Correct programming. External
arming only possible at external
readers!
Check End-of-line resistor and
remove existing 12k1 if necessary
Terminate input with 12k1
Check wiring and voltage supply
of blocking element
Check JP14. Note actuation
method
Check connection (color of the
wires)
Correct programming
Connection between door strike
operating voltage and 0V of BUS-2?
See note in Point 9.6 to rectify.
Equip DC door strike with a free-
running diode
