Relay response to malfunctions (see chapter 6 Troubleshooting):
The relay picks up when the
loop is activated and drops
out when the loop is exited.

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 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.

In a device with 2 outputs, output 2 can be either activated or deactivated.
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
