Conditions Needed to Set the Fault Code
The E1 Curtis Speed Controller is communicating a problem to
the A1 Control Board.
The Scrub Deck Actuator has drawn more than 4.5 amps.
The Solution Solenoid Valve has drawn more than
approximately 1 amp.
The Vacuum Contactor has drawn more than approximately 1
amp.
The Brush Contactor has drawn more than approximately 1
amp.
The Detergent Pump has drawn more than approximately 1
amp.
The driver IC for the Detergent Pump is reporting a fault;
current limiting or shutdown is in effect due to either a detected
over-current or over-temperature condition.
The driver IC for the Deck Actuator is reporting a fault; current
limiting or shutdown is in effect due to either a detected over-
current or over-temperature condition
The measured current was below the minimum value while the
Solution Solenoid should have been on.
The measured current never exceeded the minimum threshold
while moving from one deck position to another (only valid
when the target position and the starting position switch states
should be different).
The measured current was below the minimum value while the
Brush Contactor should have been on.
The measured current was below the minimum value while the
Vacuum Contactor should have been on.
The measured current was below the minimum value while the
Detergent Pump should have been on.
The measured current was greater than or equal to the
minimum threshold value while the deck was moving, but the
software timed out looking for the new position (never saw the
actuator switch states read the target values).
The measured current was above the minimum value while the
Solution Solenoid driver should have been off.
The measured current was above the minimum value while the
Brush Contactor driver should have been off.
The measured current was above the minimum value while the
Vacuum Contactor driver should have been off.
The measured current was above the minimum value while the
Detergent Pump driver should have been off.
An error has been generated via the serial communications
between the charger and the A1 Control Board due to an
incorrect charging profile code being repeatedly sent by the
charger, or the bit timing being severely out of spec.
