Entrance Keypad
„
Before examining the ICS Tunnel Master® Jr. Relay Box 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 ICS Tunnel Master® Jr. Relay Box 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 ICS Tunnel Master® Jr. Relay Box 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.

Check the inputs indicator lights in the upper left corner of the relay box display panel are displaying
properly. There are four possible inputs into the Controller that if not functioning could cause the
system to not respond properly:

Clock
– With the conveyor running the clock light should be blinking consistently. This insures that
the pulse switch is operating properly. If this is not operating properly, you can go into the wash
settings and change Auto Pulse to Y. With this option turned on, the controller will simulate a pulse
count. In order for this to work properly, you must have the Auto Pulse Period correct in the wash
settings.
