Tunnel Master Jr. Controller System Diagnosis
The following diagnostic procedures are provided for use only when the ICS Tunnel
Controller System has stopped responding or is not functioning. If you determine
after reviewing the diagnostic procedures the system is malfunctioning, write down
the specific conditions and contact your OEM vendor.
Entrance Keypad
Before examining the ICS Relay Controller, a test should be performed at the
Entrance Keypad to ensure that it is functioning properly. Press the AC (All Clear)
key located in the lower right corner of the numeric keyboard two or three times
while there are no cars in or near the gate switch. Now press any of the numbered
service buttons on the keypad. The indicator light should turn red as soon as the
service button is pressed.
Check the Power light in the upper right hand corner of the keypad to verify that it
is lit. If the light is not lit then the keypad is not receiving power from the OEM
Relay Controller
Check the Logic light in the upper right hand corner of the keypad. This light
should be blinking indicating that the system processor is functioning.
Check the Data light in the upper right hand corner of the keypad. This light should
be blinking indicating that the keypad is communicating with the OEM Relay
Controller.
Wash Controller Response
At the Controller Relay Box verify that there is a read out on the display at the top
of the relay box. If not, the relay box may not have power.
Check the +5V DC light located in the upper left corner of the relay box display
panel. This light should be lit at all times to verify that the controller has power.
Check the Logic light in the upper left corner of the relay box display panel. This
light should be blinking indicating that the system processor is functioning.
