Error Indication Alarm Troubleshooting Guide

The operation of error indication alarms is described in Chapter 4. When checking for correct
equipment operation in the following guide, be aware that all heaters will go off immediately after
an error indication alarm occurs if the operator takes no action. With the exception of the fuses,
there are no user-replaceable parts on the printed circuit boards. If there is a non-fuse failure on any
of the PCBs, the PCB must be replaced.
Some of the procedures in the following Troubleshooting Guide require poten-
tially dangerous electricity to be present. Only qualified service personnel should
perform these procedures.

D SERIES V6 DCL ASU Manuals
Solution
1. Re-program setpoints, allowing a
larger deviation between the high
and low limits.
2. Replace hopper sensor if resistance
does not comply with the resistance
table in this manual.
3. If the hopper status LED on the Tem-
perature Module is Off and the hopper
temperature continues to rise, the
triac on the power module has failed.
The module must be replaced.
