5441-671 WOODWARD

If the output is configured as "Impulse", the discrete output

will enable for the time configured in parameter "3416 GCB

time pulse". An external holding coil and sealing contacts

must be installed into the GCB closing circuit if this discrete

output is configured for an impulse output signal.

Steady

If the relay is configured as "Steady", the relay will energize

and remain enabled as long as the discrete input "Reply

GCB" remains de-energized and the generator and busbar

voltages are identical. If a class C or higher alarm occurs,

this discrete will disable and the GCB will open immediately.

Relay output [R

07]

Fixed to "Command: open GCB"

Programmable

Not applicable for application mode A01 .

The parameter ╚═▷ 3403 defines how this relay functions.

• If this output is configured as "N.O.", the relay contacts •

close resulting in the GCB opening circuit energizing.

• If this output is configured as "N.C.", the relay contacts •

open resulting in the GCB opening circuit deenergizing.

•• If this output is configured as "Not used", this relay is

freely configurable. The LogicsManager for Relay 7 is

preconfigured to "04.70 Opening GCB active" (This

pre-configuration is similar to the "N.O." logic).

Relay output [R

08]

Fixed to "Command: close MCB" Only applicable for application mode A04 .

The discrete output "Command: close MCB" is an impulse

output signal.

This discrete output is enabled for the time configured in

parameter "3417 MCB close command".

An external holding coil and sealing contacts must be

utilized with the MCB closing circuit.

Relay output [R

09]

Fixed to "Command: open MCB"

Programmable

Only applicable for application mode A04 .

The parameter ╚═▷ 3398 defines how this relay functions.

•• If this output is configured as "N.O.", the controller

enables this discrete output when the MCB is to be

opened for switching operations.

If the discrete input "Reply MCB" is energized, the

discrete output "Command: open MCB" is disabled.

•• If this output is configured as "Not used", this relay is

freely configurable. The LogicsManager for Relay 9 is

preconfigured to "04.22 Opening MCB active" (This

pre-configuration is similar to the "N.O." logic).

Relay output [R

10]

Programmable

Preconfigured to "Auxiliary services"

The auxiliary services output (LogicsManager 03.01) will be

enabled with the start command (prior to the engine start

because of the prerun time) and remains enabled as long

as the engine is running.

It will be disabled after the engine has stopped and the

postrun time has expired.

The auxiliary services output (LogicsManager 03.01) is

always enabled in MANUAL operation mode.

Relay output [R

11]

Programmable

Preconfigured to "Warning alarm"

This discrete output is enabled when a warning alarm (class

A or B alarm) is issued.
