1.9 I/O Setup Menu

Note: Have setup
Decision-Makerr 3500 controller performed only
by an authorized Kohler distributor/dealer. There
is a lot of setup information that can be accessed
on this screen, but the parameters should be
adjusted only during commissioning.
Analog and Digital Input Setup
There are three types of inputs setups:
1. Analog Resistive
2. Analog Differential (used in paralleling applications)
3. Digital
Note: Analog = a sender, variable-resistant device.
Digital = a switch with contacts.
The I/O Setup Menu displays the setup of digital and
analog warning and shutdown inputs. These inputs
provide choices for configuring customized auxiliary
inputs.
The user must enable the programming mode to edit the
display. See Section 2.7 for changeable settings in this
menu.
Descriptions. Descriptions for user inputs (auxiliary
analog or auxiliary digital) may be entered using the
SiteTecht software accessory where the user
determines the descriptions.
Enabled. This menu indicates whether or not the input
is enabled. If the input is not enabled, the controller will
ignore this input signal.
Analog inputs have separate warning and shutdown
enabled choices.
Inhibit Time Delay. The inhibit time delay is the time
period following crank disconnect during which the
generator set stabilizes and the controller does not
detect the fault or status event. The controller will ignore
the input until the inhibit time expires. If the inhibit time is
set to zero, the input is monitored at all times, even when
the generator set is not running. The inhibit time delay
range is from 0 to 60 seconds.
Time Delay (shutdown or warning). The time delay
follows the inhibit time delay. The time delay is the time
period between when the controller first detects the fault
or status event and the controller warning or shutdown
lamp illuminates. The delay prevents any nuisance
alarms. The time delay range is from 0 to 60 seconds.

Additional Analog Input Entries. The analog input
selection typically requires entering four values—low
the warning, high warning, low shutdown, and high
shutdown.
Digital Output and Relay Driver Output Setup
The I/O Setup Menu displays the setup of digital status
and fault outputs and relay driver outputs (RDO). These

The user must enable the programming mode to edit the
display. See Section 2.7 for changeable settings in this
menu.
Note: Changes to the Digital Outputs description
requires the use of SiteTecht software. The
digital output can either open or close the circuit
to activate.
Optional Dry Contact Kit
Dry contact kits provide an isolated interconnection
between the generator set controller and optional
devices. Up to fourteen conditions can be specifically
identified with this kit.
A relay coil will be energized when the corresponding
engine or generator sensing device or switch monitored
by the microprocessor control board is activated.
Each relay provides one set of SPST contacts for field
connection of customer supplied indicators or alarms.
Contacts are rated for a maximum resistive load of 10A
at 120VAC.
The fifteen-relay dry contact board has four digital inputs
and two analog inputs.
