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.

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.

he sensitivity 5 (=Sensitivity) of the loop detector can be adapted in 9 stages: 51 = Lowest sensitivity, 59 = Highest sensitivity,
56 = Factory setting. The sensitivity setting depends on the frequencies (see chapter 3.6 Frequency).
In a device with 2 outputs, output 2 can be either activated or deactivated. In ProLoop 11, output 2 can also be set as an alarm output.
Four different frequencies F1, F2, F3, F4* can be set in order to avoid interference when using several loop detectors. These settings influence the
sensitivity (the sensitivity can be set in the range 1–7 for frequencies F1 to F3). F2 to F4 can be set for inductance < 150 µH and only F4 can be set for
inductance < 75 µH.
The direction logic function can only be used with a 2-loop device. Direction logic must have been set in the basic function (see chapter 3.2). Detection
can be performed from: ➝ Loop 1 to loop 2 ➝ From loop 2 to loop 1 ➝ from both directions
