1.8.3 Programmable Interface Module
(PIM)
The optional Programmable Interface Module (PIM)
provides two programmable inputs and six
programmable dry contact outputs for connection to
customer-supplied equipment. The outputs are
controlled by the RDC2 controller, and can also be
controlled remotely using the OnCue Plus program.
The PIM is mounted in a NEMA 3R aluminum enclosure,
which can be mounted indoors or outdoors. See the
installation instructions provided with the PIM.
1.8.4 Load Management
On models 8RESV, 10RESV, and 12RESV only, two
optional load management devices are available for use
when combined with a model RXT and RDT transfer
switch:
The optional Load Shed Kit mounts inside a model
RDT or RXT transfer switch.
The combined interface/load management board is
available for the Model RXT transfer switch.
Note: Load shed kits are not available with the transfer
switch supplied with models 8RESVL, 10RESVL,
12RESVL.
The load management devices provide 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.
Note: The load management devices are only
compatible with single-phase generator sets.
The load management device automatically manages
up to six residential loads. Two relays are provided to
control two independent air conditioner loads. Up to four
power relay modules (or customer-provided power
relays) can be connected for management of
non-essential secondary loads.
The load management device is controlled by the RDC2
controller. The load on the generator set is monitored,
and loads are added or shed in the order of their priority.
See the installation instructions provided with the load
shed kit or the Model RXT Operation and Installation
Manual for more information.
1.8.5 Emergency Stop Kit
An emergency stop button is available as a loose kit.
Pressing the emergency stop button causes the
generator set to shut down immediately. The generator
controller displays an emergency stop shutdown
message after the button is pressed.
E-stop assembly harness contains the E-stop, contact
block, and two leads connected to the contact block.
The harness is factory-assembled. The kit also includes
the emergency stop switch decal.
The generator set enclosure is designed with an
opening for the emergency stop button. Install the
emergency stop button as described in the TT- 1613
instructions.
RDC2 firmware to version 5.5 or higher is required for
E-stop operation. Use a personal computer (laptop) and
Kohler SiteTech software or the USB Utility to update
the controller firmware, if necessary. See TP-6701,
SiteTech Operation Manual, or TT-1636, Firmware
Update Using the USB Utility, for instructions if
necessary.
