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.
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 3.2). Detection
can be performed from:
➝
Loop 1 to loop 2
➝
From loop 2 to loop 1
➝
from both directions
