Manufacturer product number: 8440-2085

Description: Woodward: easYgen-3500XT (P1), Genset Controller, 1A/5A,

Output Type/Preset Description

Relay output [R 01] Programmable

Fixed to “Ready for operation”

CAUTION! Only relay [R 01] has an

inverse logic. The relay opens (all other

relays close), if the logical output of the

LogicsManager becomes TRUE.

This discrete output is used to ensure that the internal functions

of the controller are operating properly.

It is possible to configure additional events, which cause the con

tacts of this discrete output to open, using the LogicsManager.

Relay output [R 02] Programmable

Preconfigured to “Centralized alarm (horn)”

When a centralized alarm is issued, this discrete output is ena

bled.

A horn or a buzzer maybe activated via this discrete output.

Pressing the button next to the “3” symbol will acknowledge the

centralized alarm and disable this discrete output.

The discrete output will re-enable if a new fault condition resulting

in a centralized alarm occurs. The centralized alarm is initiated by

class B alarms or higher.

Relay output [R 03] Programmable

Preconfigured to “Starter”

The generator starting circuit is engaged when this discrete

output is enabled.

This discrete output will enable depending on the start sequence

(refer to the start sequence description in Ä Chapter 4.5.9.1

“Engine Type” on page 219) to energize the starter for the config

ured starter time (parameter 3306 Ä p. 227).

Relay output [R 04] Programmable

Preconfigured to “Fuel solenoid / gas

valve”

Fuel solenoid

The fuel solenoid for the diesel engine is energized when this dis

crete output is enabled. If the engine is given a stop command or

engine speed drops below the configured firing speed, this dis

crete output is disabled immediately.

Gas valve

The gas valve for the engine is energized when this discrete

output is enabled. If the engine is given a stop command or

engine speed drops below the configured firing speed, this dis

crete output is disabled immediately.

Relay output [R 05] Fixed

Preconfigured to “Command: open MCB”

Only applicable for application mode .

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

Output Type/Preset Description

Relay output [R 06] Fixed

Preconfigured to “Command: close GCB”

Only applicable for application modes  and .

The “Command: close GCB” output issues the signal for the GCB

to close. This relay may be configured as an impulse or constant

output signal depending on parameter 3414 Ä p. 194.

Impulse

If the output is configured as “Impulse”, the discrete output will

enable for the time configured in parameter 3416 Ä p. 194). 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.

Constant

If the relay is configured as “Constant”, 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 dis

able and the GCB will open immediately.

Relay output [R 07] Fixed

Preconfigured to “Command: open GCB”

Not applicable for application mode

The parameter 3403 Ä p. 194 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 de-energizing.

If the controller is configured for the breaker application “None”,

this relay is freely configurable.

Application mode

The open GCB command remains enabled until the GCB is man

ually closed and the discrete input “Reply GCB” is energized. The

open GCB command will be issued when a fault condition or an

engine shut down occurs.

Application mode  or

The controller enables the open GCB command when the GCB is

to be opened for switching operations. If the discrete input “Reply

GCB” is energized, the open GCB command will be disabled.

Relay output [R 08] Fixed

Preconfigured to “Command: close MCB”

Only applicable for application mode

The discrete output “Command: close MCB” is an impulse output

signal.

This discrete output is enabled for the time configured in param

eter 3417 Ä p. 197.

An external holding coil and sealing contacts must be utilized with

the MCB closing circuit.

Relay output [R 09] Programmable

Preconfigured to “Stop solenoid”

Only applicable for application mode .

Inverted function of Fuel solenoid / gas valve (preconfigured [R4])

Relay output [R 10] Programmable

Preconfigured to “Auxiliary services”

The auxiliary services output (LogicsManager 03.01) will be ena

bled with the start command (prior to the engine start because of

the prerun time) and remains enabled as long as the engine is

running.

toring

2 The unit can either monitor the phase-neutral (wye) voltages or the phase

phase (delta) voltages.

If the controller is used in a compensated or isolated network, voltage protec

tion monitoring should be configured as phase-neutral to prevent earth-faults

resulting in tripping of the voltage protections.

[Phase

The phase-phase voltage will be monitored and all subsequent parameters

concerning voltage monitoring “generator” are referred to this value (VL-L).

Phase – neutral The phase-neutral voltage will be monitored and all subsequent parameters

concerning voltage monitoring “generator” are referred to this value (VL-N).
