A POWER MODULES alarm indicates that at least one of
the power modules is registering an alarm.
(a)Open the front doors on the primary and
secondary power cabinets to see if any power
modules are showing alarms.
(b)If no power modules are showing alarms, press
SYSTEM RESET on the control panel to try to
clear the alarm. If the alarm persists, there may
be a problem in the alarm circuit on the system
controller PWB (see figures SD-8 thru SD-11)
or a problem with the alarm circuits in a power
module (see RF power module manual). If the
alarm extinguishes, it may have been false.
(c)If one or more power modules are showing an
alarm, refer to the power module manual for
trouble shooting information.
