Troubleshooting 73
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. Please see page 36 for the Auto Pulse Period formula.
•
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.
Note : 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.
