ENTER NOT OUT
     This fault occurs if Enter Arm’s Out Sensors (Read Switches) are not on when arm should be retracted. This is
when the computer has 036 (ENTER BOTH IN/WTR) off and either Input (X33-ENTER P/S OUT) or (X34- ENTER D/S OUT) is not on. Fault will only occur if the wash cycle is in progress. The Fault is delayed 15 to 21 seconds depending on conditions. If either input is off for 6 seconds after 036 is off, the Carriage motion will be paused until they are both on.

EXIT NOT OUT
     This fault occurs if Exit Arm’s Out Sensors (Read Switches) are not on when arm should be retracted. This is
when the computer has 030 (EXIT BOTH IN/WTR) off and either Input (X30-EXIT P/S OUT) or (X31-EXIT D/S OUT) is not on. Fault will only occur if the wash cycle is in progress. The Fault is delayed 15 to 21 seconds depending on conditions. If either input is off for 6 seconds after 030 is off, the Carriage motion will be paused until they are both on.

TOP NOT OUT
     This fault occurs if the Top Wheel Up Sensors (Read Switches) are not on when the Top Wheel should be up.
This is when the computer has 032 (TOP WHEEL DOWN/WTR) off and Input (X3\20-TOP WHEEL UP) is not on. Fault will only occur if the wash cycle is in progress. The Fault is delayed 15 to 21 seconds depending on conditions. If either input is off for 2 seconds after 032 is off, the Carriage motion will be paused until it on.

LOW AIR
     This fault occurs when the Low Air Pressure Input (X22) is off.

CARR JAM
     This is a Carriage jam. This fault occurs when X1 (Carriage Encoder B) has not changed state for 10 seconds
while the Carriage is being instructed to move.

OVERLOAD TRIP
     This fault occurs when the Overload Tripped Input (X23) is off. This fault indicates that a circuit breaker or a
motor protector in the MCC (3-phase panel) has tripped. Green LED on the Overload Tripped Relay in the MCC
will be illuminated when condition had been removed.

GFCI
     This fault occurs when the GFCI device in the SCC has tripped. Reset must be pressed on the GFCI device
prior to resetting the machine.

ESTOP FAULT
     This fault occurs when the E-Stop is pressed or a disconnect is turned off. This fault can be disabled from the
MISC screen of the Operator Interface. Check all E-Stops and red/yellow disconnects to remove condition.

BREAKAWAY FAULT
     This fault occurs when Breakaway Input (X26) is off. If the On-Board Wheel Cleaner is not installed, the Input
will have to be jumped out to 338 (DC Common) to remove fault condition.

LOW WATER
     This fault occurs if the Low Water Input (X27) is off. User can select if this fault shuts the carwash down or
shuts the pump off and continues to wash. If Low Water Continue Wash is selected, the system sends one
Page every time the wash shuts off the High-Pressure option due to low water. Pager Number (#2) will not be
contacted by this page.

DRIVE 1 FAULT
     This fault occurs when the Carriage Drive signals the carwash controller that it has faulted.

DRIVE 2 FAULT
     This fault occurs when the Enter Wheels Drive signals the carwash controller that it has faulted.

DRIVE COM FAULT
     This fault occurs when there is an error communicating with either of the drives.

STUCK IN BAY
     This alarm occurs when a vehicle has received a wash and never left the treadle.

NO ENTRY
     This alarm occurs when a vehicle has purchased a wash (Package inserted into the Loader) and never entered the bay.

TO TREADLE
     This alarm occurs when a vehicle has pulled into the bay (Package shifted from Loader to wash) but never
pulled onto the Treadle.

PULL OFF
     This alarm occurs when a vehicle left the bay in the middle of a wash cycle.

TIME OUT
     This alarm occurs when at least one of the Outputs (NAMED 1 – 8) and (MISC 1 – 8) is on and the status of the
output pattern has not changed for over 10 minutes.

SONAR DISCONNECT
     This alarm occurs when the controller is not receiving a signal from the Sonar.
