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 controller, 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 primary 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 the LCM o r lo ad shed kit.
1. Check that the primary controller sees the LCM or
load shed kit 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
LCM.
a. Set the Genset Maximum Percent Capacity on
the LCM or load shed kit 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 LCM or load shed kit at least 20% higher
than the Automatic Stop Minimum Percent
Load setting on the APM..
See instruction sheets TT-1574 for the LCM or TT-1609
for the load shed kit, 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 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 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.
