Output Type/Preset Description

Relay output [R 10] Programmable

Fixed to"Command: close GGB" if GGB is

activated otherwise preconfigured to "Aux

iliary services"

Only applicable for application mode ,  and .

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

signal.

This discrete output is enabled for the time configured in param

eter 5726 Ä p. 223.

An external holding coil and sealing contacts must be utilized with

the GGB closing circuit.

Preconfiguration "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.

It will be disabled after the engine has stopped and the postrun

time has expired(i.e. for operating a cooling pump). Ä “Auxiliary

operations” on page 165 for this behavior.

The auxiliary services output (LogicsManager 03.01) is always

enabled in MANUAL operation mode.

Relay output [R 11] Programmable

Fixed to"Command: open GGB" if GGB is

activated otherwise preconfigured to

"Alarm class A and B"

Only applicable for application mode ,  and .

The controller enables this discrete output when the GGB is to be

opened for switching operations.

If the discrete input "Reply GGB" is energized, the discrete output

"Command: open GGB" is disabled.

Preconfiguration "Alarm class A and B":

This discrete output is enabled when a warning alarm (class A or

B alarm) is issued ( Ä Chapter 9.5.1 “Alarm Classes”

on page 944).

After all warning alarms have been acknowledged, this discrete

output will disable.

Relay output [R 12] Programmable

Preconfigured to "Shutdown alarm"

This discrete output is enabled when a shutdown alarm (class C

or higher alarm; refer to Ä Chapter 9.5.1 “Alarm Classes”

on page 944 for more information) is issued.

After all shutdown alarms have been acknowledged, this discrete

output will disable.

LogicsManager

Relay

All discrete outputs not assigned to a defined function, may be

freely configured via the LogicsManager.

Discrete Inputs

Discrete inputs may be configured to normally open (N.O.) or nor

mally closed (N.C.) states.

Fig. 150: Discrete inputs - alarm/control inputs - operation logic

(state N.O.)

In the state N.O.:

n No potential is present during normal operation.

n If an alarm is issued or control operati888on is performed, the

input is energized.

Fig. 151: Discrete inputs - alarm/control inputs - operation logic

(state N.C.

In the state N.C.:

n A potential is continuously present during normal operation

n If an alarm is issued or control operation is performed, the input

is de-energized.

Description

1200 DI {x} Delay 2 0.08 to 650.00 s

[0.20 s]

A delay time in seconds can be assigned to each alarm or control input.

The discrete input must be enabled without interruption for the delay time

before the unit reacts.

If the discrete input is used within the LogicsManager this delay is taken into

account as well.

1201 DI {x} Opera

tion

2 The discrete inputs may be operated by an normally open (N.O.) or normally

closed (N.C.) contact.

The idle circuit current input can be used to monitor for a wire break.

A positive or negative voltage polarity referred to the reference point of the DI

may be applied.

[N.O.] The discrete input is analyzed as "enabled" by energizing the input (normally

open).

N.C. The discrete input is analyzed as "enabled" by de-energizing the input (nor

mally closed).

1202 DI {x} Alarm

class

2 An alarm class may be assigned to the discrete input.

The alarm class is executed when the discrete input is enabled.

A/[B] Warning alarm classes

C/D/E/F Shutdown alarm classes

Control Signal to issue a control command only.

If "control" has been configured, there will be no entry in the event history and

a function out of the LogicsManager ( Ä Chapter 9.3.1 “LogicsManager Over

view” on page 860) can be assigned to the discrete input.

1204 DI {x} Self

acknowledge

2 Yes The control automatically clears the alarm if the fault condition is no longer

detected.

[No] The control does not automatically reset the alarm when the fault condition is

no longer detected.

The alarm must be acknowledged and reset by manually pressing the appro

priate buttons or by activating the LogicsManager output "External acknowl

edgment" (via a discrete input or via an interface).

Notes

If the DI is configured with the alarm class "Control", self acknowledgment is

always active.

Eng.mon

Monitoring for fault conditions is not performed until engine delayed moni

toring is enabled. The engine monitoring delay time (param

eter 3315 Ä p. 167) must expire prior to fault monitoring being enabled for

parameters assigned this delay.

[Always] Monitoring for this fault condition is continuously enabled regardless of engine

speed
