Gate Amplifier Installation and Wiring
Chapter 3
Table 11 - Indicators and Control Connection Descriptions
GPS
The +28V Gate power supply provides all of the DC power for the Gate
Amplifier. All other voltages are derived from the +28V Gate power supply. If the
GPS LED is off, all of the other indicating LEDs will also be off. Confirm that
120VAC is present at the power input terminal if the GPS LED is not
illuminated.
LPS
The +5V Logic Power Supply voltage is derived from the +28V Gate power
supply. If the +28V Gate power supply power is not present the logic power
supply LED will not be illuminated.
No. Label on Gate Amplifier
Description
Function
GPS
+28V Gate Power Supply output present LED
This LED is illuminated when the gate power supply output is
present. See
below for more information.
LPS
+5V Logic Power Supply output present LED
This LED is illuminated when the logic power supply output is
present. See
below for more information.
GATE FUSE OK
External Power Supply fuse OK LED
This LED is illuminated when the fuse is “OK”. See
for more information.
GATE POWER
Gate power systems OK LED
This LED is illuminated when all onboard systems are functioning
normally. See
for more information.
