Setting hold time
Separate hold times between 1 and 255 minutes can be set at the detector for each channel. The value 0
corresponds to an infinite hold time. If the loop on a detector channel is covered for longer than the set hold
time, the detector channel runs a frequency alignment. The current detuning of the loop channel is reset.
Limiting the hold time
Limiting the hold time can be used, for example, to remove the vehicle parking on the loop automatically
once the hold time has ended. The loop can then be reused for subsequent vehicles. Permanent activation
caused by faults can also be avoided by setting the hold time appropriately.

Setting output mode (signal type)
Various output modes (signal types) can be set for the outputs.
WARNING
Switching off the direction logic (2 channel version)
The direction logic must be switched off to set the output mode, i.e.
