2. Adjustment possibilities
2.1. Sensitivity
By adjusting the sensitivity for each channel, we determine, which change of inductivity a
vehicle has to cause in order to set the detector’s output.
Sensitivity adjustment is done separately for each channel in 4 levels and according to the
dual system, with 2 DIP-switches. Adjustment for channel 1 is done with
DIP-switches 1and2
and for channel 2 with
DIP-switches 3 and 4.

2.2. Frequency
The detector’s working frequency may be selected in two common levels, to be used for both
channels. The admissible frequency range is 30kHz to 130kHz. The frequency depends on
the loop geometry, number of turns, loop supply line and the chosen switch position.
One common frequency may be adjusted for both channels with
DIP-switch 5.

2.3. Holding time
The common holding time for both channels may be adjusted with
DIP-switch 6.

After the holding time has expired, the "loop free" signal is indicated and the loops will be
automatically readjusted. The holding time of a detector channel starts with the assignment
of the respective loop.
