LED Fault Indicator

PML 90 solid state non-volatile memory
LED Indicators provide a reliable and repeatable method
of displaying a fault or status signal, even when
the power is interrupted.
The solid state memory reactivates the LED display
when the power is returned. This feature is useful
when equipment is removed from service for maintenance.
The fault display is retained when the power is restored
at the service area. The standard lens is non-diffused
with diffused type optional. Connections are made
via four
wire leads.
Cleared by DOD/OFOISR for public
release under 00-S-1235 dated April 17, 2000.

Operation
Mode 1: With power applied, a short pulse
of proper
polarity will activate or deactivate the LED output. At
this point, the solid state memory retains the last pulse
input even with loss of power. Reapplication of power
will activate the LED output in accordance with the retained
memory.
Mode 2: With no constant power applied,
a short pulse
of power of proper polarity will set the solid state memory
for the designated output. The LED display will be activated
or deactivated when power is applied allowing
proper detection of system being monitored.
