TP-6805 8/1588 Section 5 Troubleshooting
5.15 Troubleshooting Load
Management Problems
The load control module (LCM), load shed kit, and the
combined interface/load management board on the
RXT transfer switch are all load management devices
that are controlled by the RDC2 or DC2 controller. If the
load management device does not operate as
expected, follow the procedures in this section to
troubleshoot the equipment. First check that the
controller is communicating with the load management
device as shown in the following procedure. Then check
the troubleshooting tables for potential problems and
recommendations.
Also refer to the documentation provided with the load
management device for more information about
installation, connections, and operation.
5.15.1 Check Controller Firmware
Check the firmware version number on the RDC2/DC2
controller. RDC2/DC2 firmware version 4.03 or higher is
required for load management. If a Model RDT ATS with
a load shed kit is used, RDC2/DC2 controller firmware
versions 5.04 or higher is recommended. Update the
firmware if necessary.
5.15.2 Verify that the Contro ller
Recognizes the Load Shed Kit
There are three ways to verify that the RDC2 controller
recognizes the load management device.
1. On the RDC2 controller, navigate to the
Networking Menu and check the number of
modules connected and the information for remote
devices. See Figure 3 and Figure 4. The number
should equal the number of RBUS devices
connected, including the load management
device, RXT transfer switch (if used), APM (if
used), and the PIM (if used). A Model RDT transfer
switch is not an RBUS device. Power relay
modules connected to the load management
device are not RBUS devices.
2. For the RDC2 or DC2 controller, use a laptop
computer connected to the controller’s USB port
and Kohlerr SiteTech software. In the Parameters
view of SiteTech, check that the RBUS network
screen shows the correct number of RBUS devices
connected (one load management device, RXT
transfer switch, PIM, and/or APM, if used). See
SiteTech Operation Manual TP-6701 for
instructions.
3. For the RDC2 or DC2 controller, use OnCue Plus.
Go to the Controls screen and check that a Load
Shed tab is visible below the exercise information.
See the OnCue Plus Operation Manual, TP--6928
for instructions.
