Problem
Possible Cause
Solution
14. E1, Err – 1001, Err – 101 = Control unable to
sense motor movement
a. Motor not inserted full to engage pinion, motor
wires broken or disconnected
a. Disconnect power, make sure motor is
fully engaged, check for broken wires,
make sure two pin connector on motor is
connected to the two pin connection on the
PC Board labeled MOTOR. Press NEXT
and REGEN buttons for 3 seconds to
resynchronize software with piston position
or disconnect power supply from PC Board
for 5 seconds and then reconnect.
b. PC Board not properly snapped into drive
bracket
b. Properly snap PC Board into drive bracket
and then Press NEXT and REGEN buttons
for 3 seconds to resynchronize software
with piston position or disconnect power
supply from PC Board for 5 seconds and
then reconnect.
c. Missing reduction gears
c. Replace missing gears
15. E2, Err – 1002, Err – 102 = Control valve
motor ran too short and was unable to
fi
nd the
next cycle position and stalled
a. Foreign material is lodged in control valve
a. Open up control valve and pull out piston
assembly and seal/ stack assembly for
inspection. Press NEXT and REGEN
buttons for 3 seconds to resynchronize
software with piston position or disconnect
power supply from PC Board for 5 seconds
and then reconnect.
b. Mechanical binding
b. Check piston and seal/ stack assembly,
check reduction gears, check drive bracket
and main drive gear interface. Press NEXT
and REGEN buttons for 3 seconds to
resynchronize software with piston position
or disconnect power supply from PC Board
for 5 seconds and then reconnect.
c. Main drive gear too tight
c. Loosen main drive gear. Press NEXT
and REGEN buttons for 3 seconds to
resynchronize software with piston position
or disconnect power supply from PC Board
for 5 seconds and then reconnect.
d. Improper voltage being delivered to PC Board
d. Verify that proper voltage is being supplied.
Press NEXT and REGEN buttons for 3
seconds to resynchronize software with
piston position or disconnect power supply
from PC Board for 5 seconds and then
reconnect.
16. E3, Err – 1003, Err – 103 = Control valve
motor ran too long and was unable to
fi
nd the
next cycle position
a. Motor failure during a regeneration
a. Check motor connections then Press NEXT
and REGEN buttons for 3 seconds to
resynchronize software with piston position
or disconnect power supply from PC Board
for 5 seconds and then reconnect.
b. Foreign matter built up on piston and stack
assemblies creating friction and drag enough to
time out motor
b. Replace piston and stack assemblies. Press
NEXT and REGEN buttons for 3 seconds
to resynchronize software with piston
position or disconnect power supply from
PC Board for 5 seconds and then reconnect.
c. Drive bracket not snapped in properly and out
enough that reduction gears and drive gear do
not interface
c. Snap drive bracket in properly then Press
NEXT and REGEN buttons for 3 seconds
to resynchronize software with piston
position or disconnect power supply from
PC Board for 5 seconds and then reconnect.
17. Err – 1004, Err – 104 = Control valve motor
ran too long and timed out trying to reach home
position
a. Drive bracket not snapped in properly and out
enough that reduction gears and drive gear do
not interface
a. Snap drive bracket in properly then Press
NEXT and REGEN buttons for 3 seconds
to resynchronize software with piston posi-
tion or disconnect power supply from PC
Board for 5 seconds and then reconnect.
