Basic functions (see Table 4.11a for settings)
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.

4.3
Time functions , time unit
The relay picks up when the
loop is activated and drops
out when the loop is exited.
Activation pulse:
The relay picks up when the
loop is activated and drops
out again after the time t.
4.4 Sensitivity (see Table 4.11a for settings)
The sensitivity (=Sensitivity) of the loop detector can be adapted in 9 stages:
= Factory setting.
4.5
Automatic Sensitivity Boost ASB (see Table 4.11a for settings)
ASB (=Automatic Sensitivity Boost). ASB is required in order to be able to recognise trailer drawbars after activation.
4.6
Frequency (see Table 4.11a for settings)
Four different frequencies F1, F2, F3, F4* can be set in order to avoid interference when using several loop detectors.
4.7
Direction logic (see Table 4.11a for settings)
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
4.8
Output 2 (see Table 4.11b for settings)
In a device with 2 outputs, output 2 can be either activated or deactivated.
4.9
Protection against power failure
Note: The set parameter values are retained after a power failure, independent from the "Protection against power failure" function.
= Protection against power failure activated: The sensitivity is restricted to 1–5.
