Lancaster 7-LXC-50 Installation, Operating And Service Manual page 27

Problem
14. Error – 101 = Control unable to sense motor
movement
15. Error – 102 = Control valve motor ran too
short and was unable to find the next cycle
position and stalled
16. Error – 103 = Control valve motor ran too
long and was unable to find the next cycle
position
Possible Cause
a. Motor not inserted full to engage pinion,
motor wires broken or disconnected
b. PC Board not properly snapped into drive
bracket
c. Missing reduction gears
a. Foreign material is lodged in control valve a. Open up control valve and pull out
b. Mechanical binding
c. Main drive gear too tight
d. Improper voltage being delivered to PC
Board
a. Motor failure during a regeneration
b. Foreign matter built up on piston and
stack assemblies creating friction and
drag enough to time out motor
c. Drive bracket not snapped in properly
and out enough that reduction gears and
drive gear do not interface

3 seconds to resynchronize software
with piston position or disconnect
power supply from PC Board for 5
seconds and then reconnect.
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

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
