Troubleshooting
WARNING! Allow only qualified personnel to perform the following tasks.
Follow the safety instructions in this document and all other related
documentation.
WARNING! Troubleshooting activities may sometimes have to be carried out
when the melter is energized. Observe all safety instructions and regulations
concerning energized unit components (active parts). Failure to observe may
result in an electric shock.
Safety
Never disconnect cables from, or reconnect cables to, the main board
while the melter is energized.
Before breaking any hydraulic connection, always relieve system
pressure. Refer to Relieving System Pressure in Section 5, Service.
Refer to the safety information provided with optional equipment.
If the melter is removed from its sub‐base for diagnostic checks or
service, ensure that the ground lead between the chassis and the
sub‐base is re‐attached when the melter is reconnected to the sub‐base.

Troubleshooting Quick‐Checks
Before using the troubleshooting charts confirm:
whether or not service was recently performed on the melter or the
melter's settings were recently adjusted.
external inputs (if used) are functioning properly.
the standby or clock functions are not turned on (if not required or
expected at the current time).
Returning the Melter Setup to Factory Settings
By returning the melter to its factory setting many common melter problems
can be isolated to either a problem with the melter settings or the melter
hardware.
To return the melter to its factory settings, simultaneously press and hold the
Setup key and the right‐display DOWN arrow key, and then, while holding
down these keys, cycle the control switch off and on. When the melter
restarts, release the two keys.
