Kohler 20-3250 kW manual Requires optional input sensors

System Warning. Yellow lamp identifies an existing fault condition that does not shut down the generator set. A continuing system warning fault condition may cause a system shutdown. Correct all system warnings as soon as practical.

See Section 2.3.5, System Warning Lamp, for definitions of the items listed.

The following conditions cause a system warning:

DEngine functions:

d ECM yellow alarm

(DDC/MTU engine with MDEC/ADEC) d High battery voltage

d High coolant temperature d Low battery voltage

d Low coolant temperature

d Low fuel (level or pressure)* d Low oil pressure

d Speed sensor fault

d Starting aid (system status) d Weak battery

DGeneral functions:

d Auxiliary—Analog up to 7 user-selectable inputs each with a high and low programmable warning level

d Auxiliary—Digital up to 21 user-selectable warnings

d Battery charger fault*

d Emergency power system (EPS) supplying load d Engine cooldown delay

d Engine start delay

d Load shed kW overload

d Load shed underfrequency

d Master switch not in AUTO (automatic start) position

d NFPA 110 fault (National Fire Protection Association)

d System ready (system status)

DAlternator functions: d AC sensing loss d Ground fault*

d Overcurrent

* Requires optional input sensors.

Note: See Figure 2-8 in User Inputs for factory- reserved analog and digital inputs that are not user-selectable.

System Shutdown. Red lamp indicates that the generator set has shut down because of a fault condition. The unit will not start without resetting the controller, see Section 2.3.7, Controller Reset Procedure.

See Section 2.3.6, System Shutdown Lamp, for definitions of the items listed.

The following conditions cause a system shutdown:

DEngine functions:

d Air damper closed (status), if equipped d Coolant temperature signal loss

d ECM red alarm

(DDC/MTU engine with MDEC/ADEC) d Engine stalled (ECM only)

d High coolant temperature d High oil temperature

d Low coolant level d Low oil pressure

d Oil pressure signal loss d Overcrank

d Overspeed

DGeneral functions:

d Auxiliary—Analog up to 7 user-selectable inputs each with a high and low programmable shutdown level

d Auxiliary—Digital up to 21 user-selectable shutdowns

d ECM communications loss (ECM models only) d Emergency stop

d Internal fault

d Master switch in OFF/RESET position d Master switch error

d Master switch open d NFPA 110 fault

DAlternator functions:

d AC output overvoltage d AC output undervoltage

d Alternator protection against overload and short circuits

d Field overvoltage

(M4, M5, M7, or M10 alternator only) d Locked rotor (failed to crank)

d Overfrequency d Underfrequency

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