IV. DIPSWITCHES
A. After each dipswitch change the sensor launches a learning process.
DIPSWITCH LEARNING PROCESS
#1 Frequency Adjustments of Loop A (see ADJUSTMENTS)
#2 Frequency Adjustments of Loop A (with single loop) or Loop B (with Dual Loops)
#3 Relay configuration: Active (Fail-Secure) or Passive (Fail-Safe)(See Programming Step III.)
#4 Automatic Sensitivity Boost (ASB option) [recommended for improved truck 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 ( f = 0.005%). It goes back to the preset value after
detection stops.
#5 Relay A Function: Presence or Pulse (not used with dual loop in combined mode)
#6 Relay A Pulse type: Entry or Exit (used only at pulse function)
or Relay B Mode (with dual loop in combined mode) (see drawing on next page)
• Non-Directional: Relay B provides a pulse according to the dip switches #7 and #8 setting.
• Directional A B: Relay B provides a pulse only if loop A is detecting before loop B. The logic detection takes place
according to dip switches #7 and #8.
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 3 FEET).
#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)
#8 Relay B Pulse Type: Entry or Exit (used only at pulse function)
#9 Pulse Duration for Both Relays (used only at pulse function): 100 ms or 500 ms
#10 Dual Loop Mode: Independent or Combined A B (not used with single loop)
