Load Control Module (LCM) Kits GM77177-KP1-QS and -KP2-QS
Introduction
The load control module (LCM) is designed to work with
Kohler
r
residential/commercial generator sets that are
equipped with the RDC2 or DC2 controller and an
automatic transfer switch. This includes the following
generator set models:
D
14RESA and 14RESAL
D
20RESA and 20RESAL
D
48RCL (single-phase only)
The load control module automatically manages up to
six residential loads. Four power relays are provided for
management of non-essential secondary loads, and
two relays are available to control two independent air
conditioner loads.
Note:
Connect only non-essential loads to the load
control module.
The load control module provides an automatic load
management system to comply with Section 702.5 of
NEC 2008. The installer is responsible for ensuring that
the power system installation complies with all
applicable state and local codes.
Two kits are available with either a pre-wired harness or
terminal blocks for customer connections.
See
Figure 1. The pre-wired harness requires installation of
the LCM within 2 feet of the distribution panel. The load
control module with the optional pre-wire harness is
shown in Figure 2.
Figure 3 shows the load control
module without the optional harness.
A status indicator provides visual indication that each
load is connected (green) or disconnected (red). The
status indicator also flashes to indicate a test condition.
A test button allows the operator to cycle the relays in the
order of their assigned priority.
The Kohler
r
OnCue
r
program can be used to monitor
the LCM operation and to label the loads with
easy-to-understand text.
See TP-6796, OnCue
Software Operation Manual.
RDC2/DC2 controller firmware version 4.3 or higher is
required for LCM operation. Check the version number
on the controller and update the controller firmware, if
necessary.
Before starting the installation, confirm that the
generator set is equipped with one of the controllers
shown in Figure 4.
Read the entire installation
procedure and compare the kit parts with the parts list at
the end of this publication. Perform the steps in the
order shown.
