1.6 Accessories

The following optional accessories are offered for the 6VSG generator sets.

1.6.1Carburetor Heater

An optional carburetor heater is recommended for improved cold starting in locations where the ambient temperature drops below 0°C (32°F). The carburetor heater prevents condensation and carburetor icing. The heater requires a continuous source of AC power.

See the generator set Installation manual for more information.

1.6.2OnCue® Generator Management System

The Kohler® OnCue® Generator Management System allows monitoring and control of your 6VSG generator set from a personal computer located in your home or at other remote locations. OnCue® can also be configured to send email or text message notifications in the event of a generator set fault.

Note: Be sure to obtain the correct version of the OnCue® kit for the VSC controller.

OnCue® version 3.1 or higher is required for 6VSG generator sets.

1.6.3Programmable 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 VSC controller, and can also be controlled remotely using the OnCue® 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.

1.6.4Communications Kit

The optional communications kit includes the following factory-installed items:

•Interface board with factory-set inputs and outputs and customer connection terminal blocks

•Fuel pressure switch

•Enclosure intrusion alarm switch
