Function
Description
1
Collective fault /
Power failure
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
Pedestrian pivot barrier in
home position
When the blocking element is in one of the end positions,
a permanent signal is output.
3
Display "passage free" left
At free passage left, a permanent signal is output here.
You can also use this output to lock an impulse generator
for passage to the right if passage to the left is cleared.
4
Display "passage free" right At free passage right, a permanent signal is output above
this exit.
You can also use this output to lock an impulse generator
for passage to the left if passage to the right is cleared.
5
Counter pulse left
A counter pulse is given via this output when the end
position is reached after passing in left hand direction.
This is also true for permanent open mode.
6
Counter pulse right
A counter pulse is given via this output when the end
position is reached after passing in right hand direction.
This is also true for permanent open mode.
Table 5: 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.
