Figure 64 Optional 15-Relay Dry Contact Kit
The optional 4-input/15-output module (see Figure 64 and Figure 65) provides normally open and normally closed contacts to
activate warning devices and other user-provided accessories allowing remote monitoring of the generator set. Connect any
controller fault output to the module. Typically, lamps, audible alarms, or other devices signal the fault conditions.
The 4-input/15-output module is factory-installed and connected to the controller.
A personal computer with Kohler
®
SiteTech™ software is required to assign the inputs and outputs. SiteTech™ is available only
to Kohler-authorized distributors and dealers.
The module has four digital inputs and two analog inputs. There are fourteen programmable relay outputs (K1
– K14) and one
common fault relay output (K15).
When a generator fault condition occurs, the contact kit relay is energized. The relay energization corresponds to the controller
output being activated.
Check the electrical requirements of the user-supplied accessories prior to installation of the relay dry contact kit. User-supplied
accessories require their own electrical source and must not exceed the relay contact ratings.
Connect to the normally open (NO) or normally closed (NC) terminals as required for each accessory. The relay contacts (K1 to
K14) are rated:

10 amp @ 120 VAC

10 amp @ 28 VDC (max.)

0.01 amp @ 28 VDC (min.)
The common fault relay contact (K15) is rated:

500 mA @ 125 VAC

2 amp @ 30 VDC
