TTL logic LOW if power supply is seated into system con-
nector. This is a short pin. A logic HIGH if the PSU is
removed
Active TTL LOW when output is within regulation limits.
A HIGH logic level if the input voltage is within allowable
limits. A TTL logic HIGH level, and a 5mS early warning
signal before 48.0v DC output loss of regulation.
A TTL logic HIGH, when operating within allowable
temperature range.
This signal is connected to a short pin on the PSU
When left open power supply operation will be inhibited.
When the power supply is inserted into the system, this
pin will be pull low by the system and turn the power sup-
ply on only after all other power supply pins have seated.
