40 Amp Tap Commander
Installation Guide
The 40 Amp
Tap Commander ™ connects to the Rectifier and
Hero 1 or Hero 2 Rectifier Monitor and
allows the user to adjust the output voltage of the rectifier locally, remotely via OmniView or
automatically to keep the rectifier output current relatively constant.
1.
Verify the following components are included in the package and are free from damage:
•
Tap Commander Module
•
Tap Commander Interface Cable (6’)
•
Tap Power Cable
•
14 Yellow Tap Wires
•
Snap-Track (for mounting the Tap Commander)
•
Installation Instructions
2.
Before installing the Tap Commander:
•
Using a multimeter, measure and record the Shunt Voltage
•
Using a multimeter, measure and record the Output Voltage
•
Using a multimeter, find and mark two Taps that measure 11-15 VAC between them. These
will be Power Taps for the 40 Amp Tap Commander.
•
Install the Hero RMU (see installation guide included with the Hero)
•
During the installation of the Hero, route the Tap Commander Accessory cable through the
conduit. See the note on the next page if you must cut the 4 pin connector off.
•
Make sure the current protection wires are firmly screwed down on the external Interrupter
Relay connections.
•
Turn on the AC power to the rectifier and confirm the
Blue Heartbeat LED
on the Hero board
is blinking once per second (this can take up to ten minutes)
•
The external Interrupter Relay must be wired correctly and operational before installation
of the Tap Commander.
o
Hero 1
–
Test the Interrupter Relay by issuing a Rectifier Off command from
Omniview. Confirm the relay is open by using a multimeter to measure mV across
the shunt, the mV reading should be zero. After confirmation, issue a Rectifier On
command from Omniview.
o
Hero 2
-
Test the relay by pressing and holding the red “Interrupter Relay” button
for three seconds, on the Hero 2 Interface Board. The
Red LED
should illuminate
below the red “Interrupter Relay” button signifying the relay is open. Confirm the
relay is open by using a multimeter to measure mV across the shunt, the mV reading
should be zero. After confirmation, press and hold the red “Interrupter Relay”
button until the
Red LED
goes out on the Interface Board.
NOTE: The button on the
Interface Board are only active when the blue Heartbeat light is flashing.
•
The external Interrupter Relay is an integral part of the Tap Commander design. If the
external Interrupter Relay is not working correctly,
do not
proceed with installation of the
Tap Commander until that problem is resolved
3.
Installation:
•
Power down the AC to the Rectifier
•
Remove the shorting bars from the rectifier
