1. General information
1.1 About the Operator's manual
This AGC-4 Operator's Manual describes the DU-2 display unit buttons and LEDs, LCD display, alarm handling and the log list.
A TDU 107 can be used instead of a DU-2. This touch screen display unit has its own operator's manual.
CAUTION
Read this document before starting to work with the controller. Failure to do this could result in human injury or damage to
the equipment.
1.2 Warnings, safety and legal information
1.2.1 Warnings and notes
Throughout this document, a number of warnings and notes with helpful user information will be presented. To ensure that these are
noticed, they will be highlighted as follows in order to separate them from the general text.
Warnings
DANGER!
This highlights dangerous situations. If the guidelines are not followed, these situations could result in death, serious
personal injury, and equipment damage or destruction.
CAUTION
This highlights potentially dangerous situations. If the guidelines are not followed, these situations could result in personal
injury or damaged equipment.
Notes
INFO
Notes provide general information, which will be helpful for the reader to bear in mind.
1.2.2 Factory settings
The Multi-line 2 unit is delivered from factory with certain factory settings. These are based on average values and are not
necessarily the correct settings for matching the engine/generator set in question. Precautions must be taken to check the settings
before running the engine/generator set.
1.2.3 Legal information and disclaimer
DEIF takes no responsibility for installation or operation of the generator set or switchgear. If there is any doubt about how to install
or operate the engine/generator or switchgear controlled by the Multi-line 2 unit, the company responsible for the installation or the
operation of the equipment must be contacted.
INFO
The Multi-line 2 unit is not to be opened by unauthorised personnel. If opened anyway, the warranty will be lost.
Disclaimer
DEIF A/S reserves the right to change any of the contents of this document without prior notice.

2.3 Modes
If the MODE button is pushed, a selection of possible running modes appears in the fourth display line.
Using the and buttons moves the cursor, and the appropriate mode can be selected by pressing the SEL button:
Mode Description
SEMI • The display buttons (START, STOP, GB ON, GB OFF) are active and can be used by the operator.
• The regulators are also active, that is, the speed control will bring the generator to nominal speed upon start.
• When pushing a breaker button for closing, the AGC will synchronise (if allowed) the breaker. When the breaker
closes, the controls stop.
TEST • The controller will start the generator, carry out the test sequence (pre-defined time period) and stop the generator
again. Subsequently, the generator will return to AUTO or SEMI-AUTO mode. The mains breaker will remain closed,
and the generator breaker will remain open. NOTE: The test running can be: Simple test: starting the genset without
closing the GB; Load test: parallel to the mains and take load to a pre-defined value; Full test: transfer the load to the
genset and open the MB.
AUTO • The controller will automatically carry out the control type selected (AMF, fixed power, and so on).
• The display control buttons (START, STOP, GB ON, GB OFF) are disabled.
• Mains controller in local (parameter 8021): If the selected running mode is fixed power, mains power export, load
takeover or island, timer start/stop (week watch) or binary input, then start/stop can be used.
MAN* • The display buttons (START, STOP) are active and can be used by the operator.
• The regulators are not active, that is, speed (and voltage) control has to take place using binary inputs for UP and
DOWN control.
• The breakers will be able to open or close at any time. A synchronisation check will always be performed to ensure
safe closing of the breakers.
BLOCK • The controller will not be able to start the equipment. BLOCK mode can be selected during standstill and the
password is needed to exit BLOCK mode. If BLOCK mode is selected while the genset is running, the mode will have
no effect until the genset is stopped. To select another mode after BLOCK mode, the password must be entered.
*Note: Manual mode is not available on the German controller.
To return to the other display functions from MODE selection, press the BACK button.

LAMP TEST
1. LED indicates that the auxiliary supply is switched on.
2. LED indicates that the controller is OK.
3. See Alarm inhibit in the Designer's reference handbook.
• In group and plant controllers, this is the power management CAN bus communication status.
4. LED indicates that auto mode is selected.
• In group and plant controllers, this is replaced by the status LEDs next to the AUTO and SEMI buttons.
5. LED is green if the mains is present and OK. LED is red for a measured mains failure. LED is flashing green when the mains
returns during the "mains OK delay" time.
OPERATOR'S MANUAL 4189340690E EN Page 11 of 24

6. LED green light indicates that the mains breaker is closed. LED is flashing yellow if the "MB spring loaded" signal from the
breaker is missing or the MB load time has not expired.
7. LED green light indicates that the generator breaker is closed. LED yellow light indicates that the generator breaker has received
a command to close on a black bus, but the breaker is not yet closed due to interlocking of the GB. LED is flashing yellow if the
"enable GB black close" or the "GB spring loaded" signal is missing or the GB load time has not expired.
8. LED green light indicates that the voltage/frequency is present and OK.
9. LED indicates that the generator is running.
10. LED flashing indicates that unacknowledged alarms are present. LED fixed light indicates that ALL alarms are acknowledged,
but some are still present.
11. German AGC only: TEST LED.
2.4.1 LED colour schemes
There are two colour schemes for the display LEDs. If LED colour scheme 2 is required, use parameter 6082 (DU-2 only) to select it.

For Genset and Group controllers, the priority is shown in the lower right corner of the display. You can use the PC utility software to
change the priority.
3.3 Password management
The controller includes three password levels. All levels can be adjusted in the PC software.
Password level Factory setting Access
Customer Service Master
Customer 2000 X
Service 2001 X X
Master 2002 X X X
A parameter cannot be entered with a password that is ranking too low. But the settings can be displayed without password entry.
Each parameter can be protected by a specific password level. To do so, the PC utility software must be used. Enter the parameter
to be configured and select the correct password level.
The password level can also be changed from the parameter view in the column "Level". Right-click the field, select "Change access
level" and then select the required password level.
OPERATOR'S MANUAL 4189340690E EN Page 14 of 24

3.3.1 Parameter access
To change parameters, the user must be logged on with the required access level (master, service or customer). If the user is not
logged on at the correct access level, it is not possible to change the parameters.
INFO
The customer password can be changed in jump menu 9116. The service password can be changed in jump menu 9117.
The master password can be changed in jump menu 9118.
INFO
The factory passwords must be changed if the operator is not allowed to change the parameters.
INFO
It is not possible to change the password for a higher level than the password entered.
3.4 Setup
The setup menu system is used to configure the controller. It includes information that is not available in the view menu system.
From the entry window, select SETUP in the line 4.
