Entrance Keypad Diagnostics - ICS Tunnel Master Jr. User Manual

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:
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.
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.

solid, if you press it again, it will shut off, if you press it again, it will flash again. Do this for
each one of the numbers. The roller button will be off, if you press it once, it will turn on, if
you press it again, it will turn off. If you press the AC button, it will toggle all of the number
keys. If you press the $ (dollar) key or the up arrow, the printer will print, "this is a test..., "
