Solution
Check wiring to the motor to ensure no bare wires
are touching and that no wires are shorted to ground
Unplug the directional valve (so pressure will not
build) and try to move the motor again. If this
succeeds then the power pack may need to be
replaced. If the motor is still unable to move, the
bearings or hydraulic pump have likely failed in the
motor and will need to be replaced.
If temperature rises for a zone that has been
disabled, replace Temperature Control Module
Visually check circuit breaker for a tripped condition
Measure voltage across input terminals on power line
filter. Voltage should measure between 190 and 264
Vac
Check for loose or disconnected wires or plugs
Measure resistance of heater(s)
Check for MCM software update, load latest MCM
software, if problem persists contact Graco
On the ADM go into the Setup screens to the System
screens then make sure that the pump sizes are
defined correctly
If the user has to be able to take the shot the system
must be fitted with smaller pumps
Increase the time/volume/weight of the shot
