System Troubleshooting
Symptom Possible Cause Remedy
Will not start
injection or has
stopped during
injection sequence

Check (36) for signal (should be off)
Note This valve also resets all circuits to off when
air pressure to the system is moved from an
off state to on. If circuits are not resetting on
startup this valve is faulty.
Catalyst overpressure circuit is
engaged (indicated on control
panel) Check for blockage in catalyst system delivery lines
Check FC 04 for proper adjustment
Will not start
injection or has
stopped during
injection sequence
Catalyst overpressure circuit is
engaged (indicated on control
panel)
Check for air leaks on catalyst overpressure valve and
connection 1B-7(21)
Check internal catalyst overpressure circuits
 Check (21) for leaks

Check V03 output (49) for signal (should be off)
Predetermined
counter not
counting or
skipping counts
Will not count in recirculation
mode Make sure unit is in injection mode
FC 03 not adjusted properly
Adjust FC 03 for proper flow. See Innovator II Control
Panel manual.
Faulty signals from powerhead
shift block Repair or replace powerhead shift block
Faulty RGA V03 valve or OR09
shuttle Check (60) for signal. It should cycle on and off with
pulses from powerhead.
Faulty counter
Check (60) for signal. It should cycle on and off with
pulse from powerhead.
Catalyst
overpressure
circuit does not
stop pump
FC 04 not adjusted properly
Adjust flow control

Remove (21) from catalyst overpressure valve,
start pump, then slowly turn FC 04 until pump
stops
MPG will not stop
pump on
overpressure
Excessive pressure Reduce MPG pressure from panel
FC 04 not adjusted properly
Adjust flow control
 Remove (26) from MPG valve, slowly turn in FC
06 until pump stops
Gel Alarm time
incorrect
FC 03 not adjusted properly
Adjust flow control until gel alarm set correctly
Gel Alarm not
working
FC 03 not adjusted properly
Adjust flow control until gel alarm set correctly
Check RGA V02 (51) for signal – should be off/pulsing
when pumping and on when not pumping
Check RGA V02 output (52) for signal – should be
off/pulsing when pumping and on when not pumping
Flush dwell time
incorrect
FC 05 not adjusted properly
Adjust flow control until flush dwell is set correctly
Flush not working FC 05 not adjusted properly Adjust flow control until flush dwell is set correctly
