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 GPS
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 LPS
below for more information.
GATE FUSE OK External Power Supply fuse OK LED This LED is illuminated when the fuse is “OK”. See GATE FUSE OK
on page 50 for more information.
GATE POWER Gate power systems OK LED This LED is illuminated when all onboard systems are functioning
normally. See GATE POWER
on page 50 for more information.
POWERFLEX DC SAR GATE
INPUT
PowerFlex DC Stand Alone Regulator Gate Input Input for the PowerFlex DC Stand Alone Regulator (SAR) Gates.
See POWERFLEX DC SAR GATE INPUT
on page 50 for more
information.
SD3000 PLUS FWD GATE
INPUT
SD3000 PLUS Forward Gate Input Input for the SD3000 PLUS forward gates. See SD3000 PLUS FWD
GATE INPUT on page 50 for more information.
SD3000 PLUS REV GATE
INPUT
SD3000 PLUS Reverse Gate Input Input for the SD3000 PLUS reverse gates. See SD3000 PLUS REV
GATE INPUT on page 50 for more information.
RDY Normally Open relay contacts Used to indicate that the Gate Amplifier is “ready to run.” See RDY
on page 51 for more information.
EXT GATE P/S External Gate Power Supply This input is used to increase the gate driver level. See EXT GATE
P/S on page 51 for more information.
FWD - GATES Armature Forward Gates Four forward gate outputs to provide gate signals for up to four
power modules. See FWD - GATES and REV - GATES
on page 52
for more information.
REV - GATES Armature Reverse Gates Four reverse gate outputs to provide gate signals for up to four
power modules. See FWD - GATES and REV - GATES
on page 52
for more information.
120VAC Power Input to Gate Amplifier Cabinet control power. See 120VAC
on page 52 for more
information.
