D. DIP SWITCHES
After each dip switch change the sensor launches a learning process
Dip-switch #1
Frequency Adjustments of Loop A
Dip-switch #2
Frequency Adjustments of Loop A (with single loop) or Loop B (with dual loops)
Dip-switch #3
Relay configuration : active or passive.
Dip-switch #4
Automatic Sensitivity Boost (ASB option) [recommended for better trucks detection] :
During a detection the sensitivity increases automatically to 8 times the preset sensitivity given by the sensitivity potentiometer adjustment.
It is limited to the maximum sensitivity (Äf = 0.005%).
It goes back to the preset value after detection stops.
Dip-switch #5
Relay A function : presence or pulse (not used with dual loop in combined mode)
Dip-switch #6
Relay A Pulse type : entry or exit (used only at pulse function)
or Relay B mode (with dual loop in combined mode) (see next drawing)
• non-directional :
The relay B provides a pulse according to the dip switches #7 and #8 setting.
• directional A
The relay B provides a pulse only if the loop A is detecting before the Loop B.
The detection takes place according to dip switches #7 and #8 logic.
Warning : During the detection, the 2 loops have to detect simultaneously for a short period to be able to determine the movement direction.
During loop installation make sure the 2 loops are close enough to each other to ensure a common detection (typical 1m).
Dip-switch #7
Relay B function : presence or pulse or loop selection for relay B pulse : pulse on Loop B or pulse on Loop A (used with dual loop in
combined mode)
Dip-switch #8
Relay B Pulse type : entry or exit (used only at pulse function)
Dip-switch #9
Pulse duration for both relays (used only at pulse function): 100 ms or 500 ms
Dip-switch #10
Dual loop mode : independent or combined A— B (not used with single loop)
