Unitec CAME Wiring - Manual (Page 18)

System Test Procedure
The following section contains procedures for verifying the completed installation. The procedures are
written to cover up to 4 lanes of operation. Any lanes that do not have the wires connected will be
ignored by the Gate controller and do not need to be tested. The test procedure is to be performed in
lane sequence (i.e., test Lane 1, then Lane 2, etc.). If you chose to perform the procedures out of
sequence, follow the resetting of the entry unit power and Gate Controller as dictated in the initial steps
of testing for Lane 1.
Caution:
You may wish to do this test with the gate arms removed from the gates in order to
avoid damage to a vehicle if the Gate loops are malfunctioning.
Testing System Interface for Lane 1
1. Reset power to all entry units.
2. Remove any vehicles below all gate loops and merge loop.
3. Verify that all Gates have power and the gates are down. Gates should be switched to
Automatic mode.
4. Reset Power to Gate controller. As you do, note the LCD screen display on it. It should
show the Gate controller software version then go to “Idle/Scanning.” The “Wash In Use”
output Y0,Y1,Y2,Y3 are the only output/input LEDs on the PLC that should be lit. They
provide the wash in use signal at each lane to hold the customer until the gate opens.
If this is not the case, check wiring of each terminal that is incorrect based on the Gate
Controller I/O Definitions chart in Section 5.
5. Verify that the “Wash In Use” LED on the associated board of the entry unit is lit. If not,
check the wiring from Y0/Terminals 41 and 11 to the entry unit.
6. Arm a wash at the entry unit in Lane 1.
7. Verify Gate at Lane 1 opens. If not, view the LCD screen on the PLC. If it shows
“IDLE/SCANNING” still, then it is not getting the signal into X0/terminal 21 from the entry
unit. Check the wiring from terminal 21 of the gate controller to the entry unit. If it shows
“Open Gate 1,” then check the wiring from the Gate Controller Y4/Terminal 51 to the Gate
terminal strip.
8. If everything is operating correctly, X4 LED on the PLC should be lit and the LCD screen
on the Gate controller should show “Wait for Gate 1”. If not, verify wiring from X4/Terminal
31 to the Gate terminal strip.
9. With the Gate for lane 1 open, drive a car through Lane 1. Validate that the Gate lowers after
the rear of the vehicle comfortably passes off the Gate Loop. If not, consult the Gate
Controller manual for Gate loop operation.
10. After the gate for Lane 1 closes, the LCD screen on the Gate controller should either show
“Car in Merge area” (if you have a Merge loop installed). Or “Idle/Scanning”
