Wash Controller Input Check - ICS Tunnel Master Jr User Manual

Trouble Shooting
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.

Wash Controller Input Check

There are four possible inputs into the Controller that if not functioning could
cause the system to not respond properly. There are indicators in the upper
left corner of the relay box display panel. Check to see that the inputs and
indicator lights are functioning normally.
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.
Gate - With the conveyor running and a vehicle passing through the gate
switch (electric eye) the Gate indicator light should stay lit the entire time a
vehicle is activating the gate switch. If this function is not operating properly,
you can go in to the wash settings and change the Auto Gate to Y. With this
option set to Y, the controller will simulate the gate sensor. This will tell the
system that every car that goes through the tunnel is the Max Car Length
value that is set in the wash settings. In order for this function to work
properly, you must set the Auto Gate Delay in the Wash Settings. The Auto
Gate Delay is the distance from where the start of the car normally is and the
Gate sensor.
Tire – With the conveyor running and a vehicle passing through the tire
switch the Tire indicator light should stay lit the entire time a vehicle is
activating
the tire switch.
Panic – If a Panic circuit has been wired into the controller, anytime a stop
switch is activated the Panic indicator light will go out. Once the stop switch
or circuit is open again the light will come back on and the conveyor will
become operable again.

Tunnel Master
In some cases, a low oil level switch for the hydraulic power pack
may be wired into the panic circuit. As a precaution, always check the
oil level in the power pack to be sure there is enough oil.
If any of the above inputs are not functioning properly, first check
the device. If the device is working properly, then check the wiring to
the circuit board in the relay box for loose or disconnected wires to
the termination points in the upper left corner of the Relay Box.
