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.

Note: The set parameter values are retained after a power failure, independent from the “Protection against power failure” function.
P 1 = Protection against power failure activated: The sensitivity is restricted to 1–5.

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 2 to 1. 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 can be deactivated in a 2-loop device.

Output
Output
The sensitivity 5 (=Sensitivity) of the loop detector can be adapted in 9 stages: 51 = Lowest sensitivity, 59 = Highest sensitivity,
54 = Factory setting.
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.
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 4.2). Detection
can be performed from: ➝ Loop 1 to loop 2 ➝ From loop 2 to loop 1 ➝ from both directions
ASB (=Automatic Sensitivity Boost). ASB is required in order to be able to recognise trailer drawbars after activation.
