Reboot the system. Refer to IM-UPS
manual.
Product not loaded. Load product. Refer to IM-UPS manual.
Machine Status message indicates low air,
or required home, clear, or in position
swi tch is n ot made.
Refer to maintenance manual, adjust
switch or air as required.
Anvil home (VCD and Jumper Wire) or
clinch down (Radial) swi tch failed.
Refer to maintenance procedures and
adjust or replace anvil home switch.
