SERVICE PROCEDURES AND ADJUSTMENTS
REPLACEMENT CONTROL BOARD
PROGRAMMING
Certain procedures in
this section require electrical test or
measurements while power is applied
to the machine. Exercise extreme
caution at all times and follow Arc Flash
procedures. If test points are not easily
accessible, disconnect power and
follow Lockout/Tagout procedures,
attach test equipment and reapply
power to test.
Certain components in this system are
subject to damage by electrostatic discharge during
field repairs. A field service grounding kit is required
to prevent damage. The field service kit must be used
anytime the control board is handled.
