Safety instructions
1
These devices and their accessories may only be operated in compliance with the operating instructions (intended use)!
These devices and their accessories may only be commissioned by trained and qualified personnel.
These devices may only be operated with the intended operating voltages and parameters.
If malfunctions occur that cannot be rectified, shut down the device and send it in for repair.
These devices are only allowed to be repaired by the manufacturer. Tampering and alterations are not permitted. This will invalidate all guarantee and
warranty claims.
The loop connection wiring to the loop detector must be twisted at least 20 times per meter.
Please wire the device in accordance with the terminal assignment. Make sure the terminals are assigned correctly.

Simulation
The settings of the devices in this chapter are shown and explained for the 1-loop device. The settings for loop 2 of a 2-loop device should be made using
the corresponding method.
1.Door/gate
systems
A malfunction causes
the output relay to be
released. The alarm
relay drops out.
2. Barrier
A malfunction causes
the output relay to pick
up. The alarm relay
drops out.
3. Quiescent
current
A malfunction causes the
output relay to be
released. The alarm relay
drops out.
4. Direction logic
(2-loop device
only)
A malfunction causes
the output relays to be
released. The alarm
relay drops out.
Parameters
1: Door and gate
The assigned output relay picks up when the loop is activated and drops out when the loop returns to a non-activated condition.
2: Barrier
The assigned output relay picks up when the loop is activated and drops out when the loop returns to a non-activated condition.
3: Quiescent current
The assigned output relay drops out when the loop is activated and picks up again when the loop returns to a non-activated condition.
4: Direction logic
Output 1 switches if an object moves from loop 1 to 2. Output 2 switches if an object moves from loop 1 to 2.
Both loops
must be
activated for a short time. The outputs are reset again when loop 2 returns to a non-activated condition. Both loops must have re-
turned to a non-activated condition for another direction detection.
0: Loop 2
Loop 2 / output 2 can be deactivated in a 2-loop device.
