Alarm Reset

If three power supplies are installed,
the system will notify you when any of
the three power modules fails. Con-
nect JAR to a micro-switch to turn
off the alarm that is activated when a
power module fails. See the table on
the right for pin defi nitions.
PWR Supply Failure/PWR
Fault Detect
The system can notify you in the event
of a power supply failure. This feature
is available when three power supply
units are installed in the chassis with
one acting as a backup. If you only
have one or two power supply units
installed, you should disable this (the
default setting) with JPF to prevent
false alarms.
