Plm Crosstalk Recovery Procedure - Generac Power Systems XVT076A03 Installation And Owner's Manual

1. Close the AC backfeed breaker to supply AC
power to one PWRcell Inverter AC Grid Input/Out-
put Terminals. This will allow the inverter to ener-
gize and illuminate the Inverter control panel.
2. Perform Commissioning the System
3. Modify the PWRcell Inverter PLM Channel to 0 in
the inverter 'Mod. Settings' menu.
NOTE: PLM Channel 0 is a universal channel. Only use
for inverters during programming. Do not set REbus
devices to channel 0. Do not leave inverter on channel 0.
4. Choose a channel from 2 – 12 to use as the only
number for addressing all devices on the system.
The goal is to address the system to its own unique
channel across all devices.
NOTE: Do not leave any device, including the inverter,
on channel 0 or channel 1 by the end of the process.
5. Use arrow keys to navigate to all REbus devices
(expect REbus Beacon) to change the PLM chan-
nel.
6. Access Mod. Settings for each device and change
the PLM channel to the chosen channel (step 4) for
that system. See device installation manual for
specific instructions.
7. Modify the PLM channel setpoint for the PWRcell
Inverter to match the PLM channel its REbus
devices were set to in the previous step.
NOTE: Be sure to click Save at the bottom of the menu
after modifying the channel on each device.
8. Turn off the inverter.
NOTE: It may take a few seconds for the inverter screen
to power off due to capacitance in the Power Core. Wait
until the screen goes blank before energizing the next
inverter.
9. Once the inverter is powered down, proceed to the
next inverter and repeat steps 1 – 9.
10. After programming each system separately, restore
AC power to all PWRcell Inverters by closing their
AC backfeed breakers, enable the inverters, and
all REbus devices.
11. Finish commissioning of inverter systems by per-
forming

PLM Crosstalk Recovery Procedure

For each PWRcell Inverter that has crosstalked, perform
the following procedure to clear the foreign devices from
the display after the multi-inverter system has been prop-
steps 1 – 5.
erly commissioned:
1. Power down all but one inverter.
2. Access the Installer Configuration Tool.
3. Navigate to the Inverter and select PWRcell Con-
figuration.
4. Select Clear Display to wipe the screen of that
inverter of unwanted devices from other systems
on site.
5. Follow steps 1 – 8 for Multiple Inverter System
Commissioning. See
Commissioning Procedure
6. Proceed to next crosstalked inverter and repeat
this procedure.
steps 7 - 11.
