Kohler 20-3250 kW manual Menu 9-Input Setup

2.7.9Menu 9—Input Setup

Menu 9 displays the setup of user-defined digital and analog warning and shutdown inputs. These inputs provide a multitude of choices for configuring customized auxiliary inputs.

The user must enable the programming mode to edit the display.

See Section 2.8.9 to change settings in this menu.

Note: Press the down arrow to move to the start of the next input setup.

Note: See Figure 2-8 in User Inputs for factory reserved inputs which are not user selectable.

DEnabled. 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 is not running. Analog inputs have separate warning and shutdown enabled choices.

DInhibit 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. This menu indicates whether or not the input is enabled. If the input is not enabled, the controller will ignore this input signal. The inhibit time delay range is from 0 to 60 seconds.

DTime 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 warning, high warning, low shutdown, and high shutdown.

Battle Switch/Fault Shutdown Override Switch. The battle switch function forces the system to ignore normal fault shutdowns such as low oil pressure and high engine temperature. The battle switch does not override the emergency stop and overspeed shutdown. When the battle switch function is enabled the generator set

continues to run regardless of shutdown signals where potential engine/generator damage can occur.

When this input is enabled the yellow warning lamp illuminates and stored warning/shutdown events that are ignored continue to log in Menu 5— Event History.

Shutdown Type A and Shutdown Type B. Choose shutdown type A for standard shutdown where red lamp illuminates and alarm horn sounds. Choose shutdown type B for shutdown where air damper indicator RDO-23 energizes for two seconds, red lamp illuminates, and alarm horn sounds.

Analog Input A06—Analog Speed Adjust (VSG). Analog Input A06 may be used for analog speed adjust when external control of engine speed is desired such as paralleling applications or closed transition ATS. To utilize this capability, the input must be calibrated. Refer to 2.8.12, Menu 12—Calibration.

Note: This feature is supported for Doosan, GM, and Volvo engines only.

Analog Input A07—Analog Voltage Adjust. Analog voltage adjust is a feature that the user may choose to enable. The input designated for use as Analog Voltage Adjust is analog input A07.

Enable Analog Voltage Adjust through Menu 11. Additionally, Monitor 2 or Monitor 3 may be used to enable Analog Voltage Adjust by entering the proper description (Analog Volt Adjust) for A07. When Analog Voltage Adjust is enabled, the description for A07 is Analog Volt Adjust. Changing the description using Monitor 2 or Monitor 3 disables the analog voltage adjust feature.

When Analog Voltage Adjust is enabled, no warning or shutdown may be enabled for A07.

Note: If the analog input A07 description does not match Analog Volt Adjust, input A07 will not function as the voltage adjust.

Identification and Descriptions. Descriptions for user inputs (auxiliary analog or auxiliary digital) may be entered using the Monitor II software accessory where the user determines the descriptions in upper and lower case.
