6.1.6 Two-Input/Five-Output Module
The two-input/five-output module provides a generator set mounted panel with two analog or digital inputs and five digital outputs.
See Figure 70 for circuit board components and electrical connections to the controller.

See Figure 71 for connections of analog inputs.

See the following subsection, Accessory Connections, for terminal identification.
Use a computer with Kohler SiteTech™ software to assign functions to digital outputs. Each input and output corresponds to a
controller connection. Verify that the settings are appropriate for the connected sensor, switch, or equipment.
