DELIFGenerator Paralleling Controller, GPC-3 - Generator Protection Unit, GPU-3/ GPU-3 Hydro - Paralleling and Protection Unit, PPU-3

BACK: Jumps one step backwards in the menu (to previous display or to the entry window). 

REMOTE: Activates the remote mode. The push-buttons for START/STOP/GB open/GB close are deactivated. The control is

external. 

LOCAL: Activates the local mode. The push-buttons for START/STOP/GB open/GB close are activated. 

START: Activates the engine start sequence (only active in LOCAL mode). 

STOP: 

Activates the stop sequence (only active in LOCAL mode) including cooling down. When the STOP push-button is

pressed during cooling down, the cooling down time is interrupted immediately and the ext. stop timer starts

running. 

2.3.2 LED functions

Each LED located on the display has its own function. The colour is green, red or yellow (fixed or flashing) dependent on its function.

The functions for all display LEDs are described below:

Alarm: 

LED red flashing indicates that unacknowledged alarms are present.

LED red fixed light indicates that ALL alarms are acknowledged, but one or more alarms are still present.

LED off when no alarm is present.

Run: 

LED yellow when a running feedback failure is active. (G V/Hz OK, but no running feedback).

LED green indicates that the generator is running and the voltage and frequency are OK.

LED off when no running feedback and no voltage and frequency are measured.

G V/Hz (~): LED yellow when the DG is running and V/Hz not OK.

LED green when the DG is running and the V/Hz OK timer has expired.

Open: 

LED red when the breaker is tripped by a protection function.

LED yellow when the breaker is deloaded.

LED green when the breaker is open.

LED off when the breaker is closed.

Closed: 

LED yellow indicates that the synchronisation function is active.

LED green when the breaker is closed.

LED off when the breaker is open.

BB V/Hz (~): 

LED green when BB V/Hz OK.

LED yellow when BB V/Hz not OK.

LED red when BB voltage is zero (dead bus).

Ready: 

LED green when the unit is ready for operation.

LED off when the unit is not ready (for example, the start enable is not activated or an active block, trip or

shutdown alarm is present).

This indication is to tell the user whether the controller (not the engine) is ready or not. 

Regulator ON: 

LED green when the regulator is activated.

LED yellow when regulator is activated but no output has been selected for governor interface.

LED off when the regulator is off.

Remote: LED green when remote mode is active.

LED off when local or SWBD mode is active.

Local: LED green when local mode is active.

LED off when remote or SWBD mode is active.

Power: LED green indicates that the auxiliary supply is switched on.

Self check: LED green indicates that the unit is OK.

2.4 Lamp test and dimmer functions

2.4.1 Lamp test

Place the cursor under SETUP and press the push-button to activate the DU-2 lamp test.

All LEDs on the DU-2 and AOP-1 will turn yellow except the power LED.

2.4.2 Dimmer function

The dimmer function of the display backlight and LEDs is accessed via the JUMP menu 9150.

The illumination intensity of the backlight and the LEDs of each display panel is adjustable by using the JUMP push-button. This

adjustment is done by means of the and push-buttons on the display, and the level of the adjustment will be saved in

the display internal memory by pressing the ENTER push-button

Procedures for setup

INFO

The complete parameter list is presented in the separate Parameter List document of the Multi-line unit in question:

GPC/GPC Gas/GPC Hydro/GPU Hydro document number 4189340580, GPU/GPU Gas/PPU document number

4189340581.

This chapter deals with the procedure to be followed when the parameters of the unit are set up from the initial point of finding the

individual parameter description to the actual setup. By use of various illustrations, the following will guide the user through the

whole procedure of parameter setup step by step.

6.2 Finding the selected parameter

The first step in the parameter setup is to find the correct parameter descriptions. All parameter descriptions in the Parameter List

document are intended for reference purposes. The descriptions are structured according to their parameter titles and the main

parameter group to which they belong.

6.3 Parameter descriptions

In the parameter list, each parameter description is structured according to the same principles. Under the parameter title heading,

the detailed parameter descriptions are illustrated and presented. First, a table indicating the parameter facts related to the

individual parameter title is presented:

INFO

Due to the character of the parameters there may be small differences between the individual tables.

The first column indicates the menu number in the display.

The second column indicates the name of the setting.

The third column describes the function of the parameter.

The fourth column indicates the minimum/maximum set point available for this setting

The fifth column indicates the default set point of the unit from the factory. When it is necessary, additional information will be

supplied below the table in order to make the individual parameter descriptions as informative as possible.

6.4 Setup

At this point of the process, the specific parameter description will have been located. Now, follow the menu structure presented
