Appendix D - ADM Event and Error Codes Overview
Solution
Re-calibrate the machine
If any messages appeared indicating why the
calibration failed attempt to fix the problem then
re-run the calibration
Measure resistance of heater
Measure voltage across the disconnect switch.
Voltage should measure between 190 and 264 Vac.
If temperature rises for a zone that has been disabled,
replace Temperature Control Module
Replace motor
Check wiring to the motor to ensure no bare wires are
touching and that no wires are shorted to ground
Make sure the supply line is properly sized for the
load and is above the minimum voltage requirements
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
