Troubleshooting - Hellenbrand ProMate 1 Owner's Manual

PROBLEM
After resolving the cause of any error code or any service work on valve, press NEXT & REGEN simultaneously for 5 seconds or disconnect power supply for
5 seconds at PC board and reconnect to resynchronize software with piston position.
VALVE ERROR CODES
Error Code 101 - Unable to recognize
start of regeneration
Error Code 102 - Unexpected stall
Error Code 103 - Motor ran too long,
timed out trying to reach home position
MAV ERROR CODES
After resolving any MAV error or servicing MAV, resynchronize software with piston positioning by pressing NEXT and REGEN buttons simultaneously for 5 seconds
or disconnecting power from PC board for 5 seconds and reconnecting.
ALTERNATING MAV DRIVE - ERROR CODES 106 & 107
Error Code 106 - Alternating MAV ran too long
Error Code 107 - Alternating MAV stalled
1. Control valve stalled in regeneration

TROUBLESHOOTING

CAUSE
A1. Control not reading piston position
B1. Mechanical Binding
B2. Improper voltage being delivered
to board
C1. Piston unable to reach home position
Mechanical Binding
A. Motor not operating
B. No electric power at outlet
C. Defective transformer
D. Defective PC board
E. Broken drive gear or drive cap assembly
F. Broken piston retainer
G. Broken main or regenerant piston
CORRECTION
A1. Resynchronize software with piston position by
pressing start NEXT and REGEN buttons
simultaneously for 5 seconds, until screen
changes. Initiate regeneration to verify function by
pressing and holding REGEN button until regeneration
initiates, step through regeneration modes by pushing
REGEN button each time motor stops.
A2. Verify motor connection to PC board; motor wires are
intact and motor fully inserted to engage pinion,
(should also be flushed with barrel).
A3. Verify correct assembly; PC board snapped onto drive
bracket and wires are in backplate guides and drive
bracket snapped onto backplate. Verify three drive
gears are in place on drive bracket and reflective surface
are clean and gears rotate freely.
B1a. Check for any foreign material in stack assembly impeding
piston movement and remove; verify seals intact and
in place in stack assembly, if not replace stack assembly.
B1b. Check for incorrect assembly, drive bracket not snapped
into place, motor pushed inside of barrel of drive bracket
(black gear on motor end should be flush with end of shaft).
B1c. Drive gears unable to rotate freely - replace gear(s) if not
rotating freely.
B2. Motor unable to move piston, check voltage is present
on 12V DC motor at start of regeneration modes.
Transformer should provide 12 volts when plugged
into outlet and not attached to board - if not replace
transformer
C1. Incorrect assembly; check drive bracket is correctly
seated and snapped into place on backplate, wires
outside of guides on backplate can impede drive
bracket from correct position.
C2. Check PC board is seated on posts and snapped
into place on drive bracket
C3. Drive gear labels dirty or missing, missing or broken
gear, replace as needed
A1. Control valve is programmed for alternating or as
NHWB without having MAV connected to board.
Reprogram valve to proper setting or connect MAV
to alternating MAV drive on PC board
A2. MAV motor not fully engaged with gears
B1. Open MAV and check for foreign material on stack
assembly, remove if present, verify seals intact and in
place. If not, replace stack assembly
B2. Drive gear should spin freely-replace if necessary
A. Replace Motor
B. Repair outlet or use working outlet
C. Replace transformer
D. Replace PC board
E. Replace drive gear or drive cap assembly
F. Replace drive cap assembly
G. Replace main or regenerant piston
