4 Setup and Commissioning
The next procedures are required for setup and
commissioning of the paralleling system.
Note: A personal computer (laptop) with Kohler
SiteTecht software version 3.5 or higher is
required to complete the system setup.
SiteTecht software is available to
Kohler-authorized distributors and dealers.
4.1 Verify communication connections.
Check the Network Information and Remote Devices
menus on the RDC2 c ontroller, or use Kohler SiteTech to
check the RBUS Devices group parameters.
1. Verify that the primary controller recognizes the
secondary controller as a “Kohler Power
Generation Device.”
2. Check that the serial number of the Kohler Power
Generation Device seen in the pri mary controller
matches the serial number of the secondary
controller. The secondary controller will not see the
primary controller as an RBUS device.
Note: The controller serial number can be found in
the RDC2 controller’s Genset Information
menu.
4.2 Set up load management.
1. Check that the primary controller sees the load
management device as an RBUS device. Check
the Network Information and Remote Devices
menus on the RDC2 controller, or use Kohler
SiteTech to check the RBUS Devices group
parameters.
2. Use SiteTech software connected to the primary
controller to set the following parameters on the
load management device .
a. Set the Genset Maximum Percent Capacity on
the load management device to a higher value
than the Automatic Stop Minimum Percent
setting on the APM. See Figure 21 for the APM
settings.
b. Set the Generator Overload Percent setting on
the load management device at least 20%
higher than the Automatic Stop Minimum
Percent Load setting on the APM..
See TT-1574 for the LCM, TT-1609 for the load shed kit,
or TP-6807 for the RXT ATS for instructions, if
necessary.
4.3 Set up the PIM, if equipped.
If the system does not include a programmable interface
module (PIM), proceed to Section 4.4.
1. If an optional Programmable Interface Module
(PIM) is connected to the system, check that the
primary controller sees the PIM as an RBUS
device. Check the Network Information and
Remote D evices menus on the RDC2 controller, or
use Kohler SiteTech to check the RBUS Devices
group parameters.
2. Use SiteTech software connected to the primary
controller to set up the PIM inputs and outputs. See
TT-1584, provided with the PIM, for the default
input and output settings. See TP-6701, SiteTech
Software Operation manual, for instructions to
change the settings, if necessary.
3. Set the PIM settings on the secondary controller to
match the primary controller’s PIM settings.
Although the secondary controller only reads the
system status and does not control the RBUS
devices, the PIM configuration on the secondary
controller should be set up to match the primary so
that the primary status can be switched between
the controllers.
