CAME SMA Operating Instructions

The relay picks up when the
loop is activated and drops
out when the loop is exited.

On delay:
The relay picks up after the
time t when the loop is acti-
vated and drops out when
the loop is exited.

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

ASB (=Automatic Sensitivity Boost). ASB is required in order to be able to recognise trailer drawbars after activation.
Basic function 2 «Barrier systems» or 3 «quiescent current» must be set for this function.
P 1 = Protection against power tailure activated: The sensitivity is restricted to 1–5 and the time function to h.
