Function
Description
1
Global error / alarm output
When certain errors occur, an alarm is given at this
output; it continues as long as the error persists. Refer
also to the following note.
Possible errors are:
Obstruction detected
Emergency input is interrupted
CAN communication with end stage is impaired
Hardware fault in end stage
Software error in end stage
Power failure
Wire breakage in alarm line
2
Tailgating alarm output
At this output, a continuous signal is given if tailgating is
detected. The signal remains active until there is only one
object in the lane.
3
Wrong-way alarm output
An alarm is given at this output if the lane is entered from
the wrong direction. This warning is also given when an
object is in the entry zone without clearance for too long
with the pedestrian barrier closed. The signal is cancelled
as soon as the zone is cleared, or after 15 seconds.
4 Passage
counting
pulse
When a passage is detected, a counting pulse ca. 400 ms
long is given at this output. This also applies in case of
free entry/exit mode. Pulses resulting from both directions
are counted.
5
Inhibit card reader on entry
side
At this output, a card reader on the entry side can be
blocked if a passage is requested from the exit side.
6
Inhibit card reader on exit
side
At this output, a card reader on the exit side can be
blocked if a passage is requested from the entry side.
Table 8: Relay outputs
NOTE!
Relay 1 operation is fail-safe, i.e. a power failure or
a wire breakage at the relay output is also indicated
at the global error output. This means that the relay
contact pair is closed as long as there is no error.
As soon as the global error described above
occurs, the relay contacts open.
