LED indicators
Indications: LEDs 1 and 2 signal the allocation state of the loops (Loop 1 allocated = LED 1 on,
Loop 2 allocated = LED 2 on).
A fault in a loop due to a short-circuit or lead breakage and loop industance outside the
permissible range is indicated by flashing of the respective LED.
DIP switches
It is possible to modify frequency, sensitivity and operating mode by using the DIP switch.
Sensitivity
The response sensitivity of the loop detector can be set in three stages using switches 3 and 4
(for loop 1) and switches 5 and 6 (for loop 2).
Frequency switches
The loop frequency can be set in four stages using the switches 1 and 2.
