Error Mode
When a failure is detected, the control will generate and display an error or alarm code, depending on the type of failure, as
shown in the table below.
In order to clear an error code (after correcting the problem), push and hold the “Status” key for 10 seconds. After the 10
seconds, the control will clear the error code and cycle the valve to service (Home). Other methods of clearing the error
code are: powering down the control for 60 seconds, toggling a DIP switch or changing an input connection (adding or
removing a Flow Meter). If the problem is still present after clearing the error code, the error code will again be displayed.
While in error mode, the control will not function. When returning from Error mode, the control shall use the values stored
in EEPROM unless a DIP switch was toggled or an input connection (Flow Meter) was changed. In those cases, the
programmed values shall revert back to the defaults.
For E2 and E3 errors, the control is to attempt to return to home and stop. If the control is successful in finding and
stopping in the home position it is to display the error code but return to functioning as normal. If the next reconditioning
cycle is successful without errors the error code is to be removed and the control will function as normal.
Display
Error Description
Mode of Detection
Clearing Error/Alarm
Motor Failure to Start
(No switch changes)
If the valve fails to reach the desired state within 70
seconds of driving the motor. The control will attempt
to start the motor 3 times for 70 seconds each time
with a 60 second off period between each attempt.
Press and hold
‘STATUS’
key for 10 seconds
Motor Failure to Stop
(unexpected switch
changes)
If the control detects changes in the Cam inputs
when the motor is not supposed to be turning
Press and hold
’STATUS’
key for 10 seconds
Incorrect Cycle
Position
(switch changes
out of sequences)
The control expects to be in a different position
than that indicated by the Cam switch closures
Press and hold
‘STATUS’
key for 10 seconds
Cannot detect 4-cycle
valve operation
Control fails to recognize the proper cam switch
sequence upon initializing the valve.
Similar to E1 detection, the control will make
3 attempts to establish the proper 4-cycle
sequence. After the third failed attempt, the E4
code will be displayed.
Each attempt will turn the motor output on for
30 seconds, with a 30 second pause n between
attempts (30sec on, 30 sec off, 30 sec on, 30 sec
off, 30 sec on E4).
Press and hold
‘STATUS’ key for 10
seconds
When
E1
or
E4
are detected, the control should stop the motor and remain in error mode until manually cleared.
(All program settings, statistics and EEPROM values should be stored, and filter operations should
cease with the exception of time keeping)
When E2 or E3 are detected, the control should display the error code and attempt to “home” the valve,
just like it does upon a reset or initial power up.
