The current code level is indicated by the corresponding numeric

value (e.g. “Code level display”: “1”) in the configuration menu

screens. The value indicates that all parameters of a higher code

level are “locked”.

PFPower Factor

P Active Power [kW]

S Apparent power [kVA]

Q Reactive Power [kvar]

The AC power triangle illustrates the dependencies between active

power, apparent power, reactive power and power factor.

n PF = P/S = cos Φ

n Q = √(S2-P2)

n S = √(P2+Q2)

n P = S * PF

The easYgen supports two types of generators:

n synchronous generators

n asynchronous generators (induction generators)

[Synchronous] The unit provides all functions which are needed for synchronous generator

applications. Isolated and mains parallel operation is supported.

Asynchronous The unit provides the special function of the asynchronous generator with:

n The speed is regulated with the speed signal from the

MPU or J1939/CAN input (as long as the GCB is open).

n The closing of the GCB is executed, if the speed is within

the corresponding frequency range of the generator oper

ating window. The voltage and phase angle is ignored in

this case.

n The generator monitoring (under/over frequency and

under/overvoltage) is switched off, until the generator

breaker is closed.

n After opening the GCB, under/over frequency and under/

overvoltage monitoring is switched on again.

n The Frequency/MPU speed plausibility monitoring is only

active, if the GCB is closed.

n The synchroscope is not displayed in the asynchronous

modus

Recommended settings

The asynchronous modus is normally used in mains parallel operation.

Please consider the following settings:

n Application mode (parameter 3401 Ä p. 192) =

GCB/MCB

n MCB control (parameter 5733 Ä p. 197) = Off

n Mains decoupling (parameter 3110 Ä p. 137) = GCB

n Emergency run (parameter 2802 Ä p. 233) = Off

n MPU input (parameter 1600 Ä p. 231) = On

n Generator operating frequency (parameter

5802 Ä p. 109. 5803 Ä p. 109)

Notes

The asynchron mode is not recommended for emergency power applications.

1750 System rated

frequency

2 50 / 60 Hz

[50 Hz]

The rated frequency of the system is used as a reference figure for all fre

quency related functions, which use a percentage value, like frequency moni

toring, breaker operation windows or the Analog Manager.

1601 Engine rated

speed

2 500 to 4.000

rpm

[1.500 rpm]

Number of revolutions per minute of the engine at rated engine speed. The

speed control with an ECU via J1939 CAN bus refers to this value.

1766 Generator

rated voltage

2 50 to 650000 V

[400 V]

This value refers to the rated voltage of the generator (generator voltage on

data plate) and is the voltage measured on the potential transformer primary.

The generator rated voltage is used as a reference figure for all generator

voltage related functions, which use a percentage value, like generator

voltage monitoring, breaker operation windows or the Analog Manager.

1768 Mains rated

voltage

2 50 to 650000 V

[400 V]

This value refers to the rated voltage of the mains and is the voltage meas

ured on the potential transformer primary.

The mains potential transformer primary voltage is entered in this parameter.

The mains rated voltage is used as a reference figure for all mains voltage

related functions, which use a percentage value, like mains voltage moni

toring, breaker operation windows or the Analog Manager.

1781 Busbar 1 rated

voltage

2 50 to 650000 V

[400 V]

This value refers to the rated voltage of busbar 1 and is the voltage measured

on the potential transformer primary.

If voltage measuring is configured to 1Ph 3W, the WYE voltage (VL1N) must

be entered here.

The busbar 1 potential transformer primary voltage is entered in this param

eter. The busbar rated voltage is used as a reference figure for all busbar

voltage related functions, which use a percentage value, like synchronization.

1752 Gen. rated

active power

[kW]

2 0.5 to 99999.9

kW

[200.0 kW]

This value specifies the generator real power rating, which is used as a refer

ence figure for related functions. The generator rated active power is the gen

erator apparent power multiplied by the generator power factor (typically

~0.8). These values are indicated in the generator data plate ( Ä “Dependen

cies” on page 97).

1758 Gen. rated

react. power

[kvar]

2 0.5 to 99999.9

kvar

[200.0 kvar]

This value specifies the generator reactive power rating, which is used as a

reference figure for related functions. The generator rated reactive power also

depends on the generator values ( Ä “Dependencies” on page 97).

1754 Generator

rated current

2 1 to 32000 A

[300 A]

This value specifies the generator rated current, which is used as a reference

figure for related functions.

1748 Mains rated

active power

[kW]

2 0.5 to 99999.9

kW

[200.0 kW]

This value specifies the mains real power rating, which is used as a reference

figure for related functions. The mains rated active power is a reference value

used by several monitoring and control functions ( Ä “Dependen
