scrolling through screens with the navigation keys. The

top three lines of the display are allocated to mode and

status messages that continuously display the operating

mode of the control system, as well as any faults or

warning conditions that may be present on the controller.

If more than one fault or warning message is present, the

messages will scroll to allow the operator to view all active

messages in the system.

Screen-saver mode - The operator panel can be

programmed to automatically switch off to reduce battery

voltage drain when the control is not being used and the

generator set is not running. Depressing any button on the

operator panel, new fault conditions or receipt of a remote

signal at the control will “wake up” the control.

Generator set data

Generator set hardware data - Generator set rating in

kVA, complete generator set model number and serial

number, engine model and serial number and alternator

model and serial number. The control also displays the

part number of the control and the software version

present in the control.

Data logs - Number of start attempts and number of start

attempts since reset. Number of times generator set has

run and number of times since reset. Duration of

generator set running time and duration of running time

since last reset. Generator set kWh produced and kWh

produced since last reset.

Adjustment history - Record of adjustment and setting

changes made on the control, identifies whether

adjustment was made via the operator panel or with a

service tool. If a service tool is used, the control provides

a record of the serial number of the tool used. This

information is read with InPower.

Fault history - Record of the most recent fault conditions

with time stamp, along with the number of times each fault

has occurred. At least 20 events are stored in the control

memory.

Load profile data - Data indicating the total operating

hours at percent of load in 10% increments and since

reset.

Generator set AC data

Generator set output frequency, voltage and

current - All phases (line-to-line and line-to-neutral for

voltage. Accuracy 1%.

Generator set power output - PowerCommand

displays generator set kW and kVA output (average phase,

individual phase and direction of flow) and power factor

with leading/lagging indication. Accuracy 5%.

Generator set kWh energy output - Total kWh

produced and total produced since last reset with time

stamp of time of last reset.

Digital synchroscope - Bus voltage and frequency,

generator set bus voltage and frequency, the phase angle

displacement and a signal indicating “ready to close”. A

breaker control switch is included on this panel for

convenient operation of the equipment without switching

between viewing screens.

Engine data

Basic engine data - Engine starting battery voltage,

engine lube oil pressure and engine coolant temperature.

Engine service data - Varies with engine used, but

typically includes: Engine coolant pressure, engine fuel rail

temperature and pressure, engine fuel input and output

temperature, intake manifold temperature and pressure,

ambient air pressure, crankcase blowby flow and

aftercooler inlet coolant temperature.

Engine fuel consumption - The fuel consumed by the

engine is calculated by the control based on fuel flow into

the engine and returned by the engine, and the

temperature of the two flow streams. Accuracy is +

over 500 hours of operation. Data provided includes

overall average fuel consumed and consumption since

reset. This information is read with InPower.

Engine exhaust temperature (optional).

Power transfer control data (optional)

Utility (mains) source data - Displays line-to-line and

line-to-neutral voltage of utility (mains) source, frequency

and estimated amps, and kW and kVA supplied by utility

(mains) source (optional when power transfer control is

used).

System status information - Provides graphical

system status display showing availability of sources and

positions of each contactor.

System control - Allows operator to view status of

system and manually control operation of the system.

Provides manual adjustment capability for time delay start,

stop, transfer and retransfer, as well as time delays for

program transition (when used) and power transfer overlap

time.

Internal control functions

General functions

System control voltage - The control operates on 24

VDC from the generator set starting batteries. Control

functions are fully operational over a voltage range of 8

VDC to 36 VDC.

Emergency start mode - PowerCommand accepts a

ground signal from remote devices or a network signal to

automatically start the generator set and immediately

accelerate to rated speed and voltage.

PowerCommand includes a smart starting system that is

designed to quickly start the engine, minimize black

smoke, minimize voltage and frequency overshoot, and
