Product number: 8440-2088

Manufacturer product number: 8440-2088

Description: Woodward: easYgen-3500XT (P2), Genset Controller, 1A/5A

Predecessor: 8440-1438. 8440-1762. 8440-2238

The load sharing messages are monitored. In case of a “missing

member” alarm on the load share bus, the single dead bus clo

sures are delayed depending on the own Generator number to

avoid simultaneous closure. The delay time is Generator Number

multiplied with 500 ms.

The GCB dead busbar closure is realized faster, if LogicsManager

“Undelayed close GCB” ID 12210 is set to TRUE.

The dead busbar negotiation is going over segments.

The synchronization is active, if the following conditions are met

simultaneously.

The display indicates “Synchronization GCB” or “Synchronization

MCB”.

Automatic operation

n The operating mode AUTOMATIC has been selected

n The mains voltage is available and within the configured oper

ating range ( Ä Chapter 4.5.3.3 “Mains Operating Ranges:

Voltage / Frequency” on page 352)

n The generator and busbar voltage are available and within the

configured operating range ( Ä Chapter 4.5.1.1 “ Generator

Operating Ranges: Voltage / Frequency / Busbar”

on page 308)

n The differential frequency/voltage is within the configured oper

ating range

n Synchronizing the MCB– The GCB is closed (or at least one GCB is closed in a mul

tiple genset application)– The busbar voltage is within the configured operating range– The “Enable MCB” (parameter 12923 Ä p. 228/Ä p. 907)

signal is present, for example discrete input 6 is energized

if configured as DI 6

n Synchronizing the GCB– The MCB is closed– The busbar voltage is within the configured operating range– Engine delayed monitoring (parameter 3315 Ä p. 167) and

generator stable time (parameter 3415 Ä p. 221) have

expired or “Undelay close GCB” (param

eter 12210 Ä p. 221/Ä p. 905) is enabled

Manual operation

n Operating mode MANUAL has been selected

n The generator and busbar voltage are available and within the

configured operating range ( Ä Chapter 4.5.1.1 “ Generator

Operating Ranges: Voltage / Frequency / Busbar”

on page 308)

n The differential frequency/voltage is within the configured oper

ating rang

signal is present, for example discrete input 6 is energized

if configured as DI 6– The button “Close MCB” has been pressed

n Synchronizing the GCB– The MCB is closed– The busbar voltage is within the configured operating range– Engine delayed monitoring (parameter 3315 Ä p. 167) and

The unit closes the MCB, if the following conditions are met simul

taneously.

The display indicates “MCB dead bus close”.

Automatic operation

n The operating mode AUTOMATIC has been selected

n The parameter “Dead busbar closure MCB” (parameter

3431 Ä p. 227) is configured On

n The mains voltage is available and within the configured oper

ating range ( Ä Chapter 4.5.3.3 “Mains Operating Ranges:

Voltage / Frequency” on page 352)

n The GCB is open or has been opened for at least the “Transfer

time GCB↔MCB” (parameter 3400 Ä p. 218) (open transition

mode only)

n The “Enable MCB” (parameter 12923 Ä p. 228/Ä p. 907)

signal is present, for example discrete input 6 is energized if

configured as DI 6

n The busbar voltage is below the dead bus detection limit

(parameter 5820 Ä p. 424)

Manual operation

n Operating mode MANUAL has been selected

n The parameter “Dead busbar closure MCB” (parameter

3431 Ä p. 227) is configured “On”
