Loop detector fine tuning:
Frequency setup:
If the default LOOP1 = “OFF, OFF” & LOOP2=”ON, ON” frequency setup is not
working well then following the test below to configure detection frequency for
individual detectors.
Use a 25 cm x 25 cm metal plate as a detection object. Hold it above the wire loop,
about 50 cm above the ground level to start. Slowly move down and reduce the
height until the metal object is detected by the loop detector. Record the detected
height for both wire loops.
Select the loop detector with less detection distance (less sensitive) to setup
detection frequency first.
Use the same metal plate to test 4 available frequencies (refer to Dip switch setting
table above: DIP9 and DIP10) on the first (less sensitive) loop detector and select a
good frequency for it.
After the frequency of first loop detector decided, test the remaining 3 frequencies
on the second loop detector and select one best frequency for it.
Sensitivity adjustment:
Applying the adjustment to both loop detectors.
Suggested detection height (sensitive range): 20 cm ~ 40 cm. (Using the 25 cm x 25
cm testing metal plate)
Sensitivity rating: 0 to F, 0 has the minimum, F has the maximum sensitivity.
Press “RESET” after sensitivity adjustment for new setting to apply.
2.2. Connect barrier gate to terminal:
2.2.1. Terminal I/O control board wiring contact points reference:
CN2 - Wiring connector for barrier gate control on terminal I/O control board V4:
BR_OP : Output signal, open barrier gate.
BR_CL : Output signal, close barrier gate.
BR_L.L : Input signal, Barrier position detection.
BR_V+ : Input power of barrier controller, +V. DC12/24V.
BR_GND : Barrier controller power grounding, for output/input signals.
JP2 – Adjust jumper according to barrier gate open/close control signal common
point:
If common point is 0V (GND), make jumper middle pin short with BR_GND.
★
Important
：
The detection frequency must be different between 2 loop detectors.
