1. General information
1.1 Warnings, legal information and safety
1.1.1 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 gener-
al text.
Warnings
Warnings indicate a potentially dangerous situation, which could result in death, personal in-
jury or damaged equipment, if certain guidelines are not followed.
Notes
Notes provide general information, which will be helpful for the reader to bear in mind.
1.1.2 Legal information and disclaimer
DEIF takes no responsibility for installation or operation of the generator set. If there is any doubt about how
to install or operate the engine/generator controlled by the Multi-line 2 unit, the company responsible for the
installation or the operation of the set must be contacted.
The Multi-line 2 unit is not to be opened by unauthorised personnel. If opened anyway, the war-
ranty will be lost.
Disclaimer
DEIF A/S reserves the right to change any of the contents of this document without prior notice.
The English version of this document always contains the most recent and up-to-date information about the
product. DEIF does not take responsibility for the accuracy of translations, and translations might not be up-
dated at the same time as the English document. If there is a discrepancy, the English version prevails.
1.1.3 Safety issues
Installing and operating the Multi-line 2 unit may imply work with dangerous currents and voltages. Therefore,
the installation should only be carried out by authorised personnel who understand the risks involved in work-
ing with live electrical equipment.
Be aware of the hazardous live currents and voltages. Do not touch any AC measurement in-
puts as this could lead to injury or death.
1.1.4 Electrostatic discharge awareness
Sufficient care must be taken to protect the terminal against static discharges during the installation. Once the
unit is installed and connected, these precautions are no longer necessary.

DEIF A/S Page 3 of 21

1.1.5 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 About the Operator's Manual
1.2.1 General purpose
This Operator's Manual mainly includes general product information, display readings, push-button and LED
functions, alarm handling descriptions and presentation of the log list.
The general purpose of this document is to give the operator important information to be used in the daily
operation of the unit.
Please make sure to read this document before starting to work with the Multi-line 2 unit and
the generator set to be controlled. Failure to do this could result in human injury or damage to
the equipment.
1.2.2 Intended users
This Operator's Manual is mainly intended for the daily user. On the basis of this document, the operator will
be able to carry out simple procedures such as start/stop and control of the generator set.
1.2.3 Contents and overall structure
This document is divided into chapters, and in order to make the structure simple and easy to use, each
chapter will begin from the top of a new page.

3.3 LCD display
The display is a backlit LCD text display containing four lines with 20 characters in each line. There is no con-
trol of the display light intensity (no dimmer). Basically, all measured and calculated values can be read in the
display. These may be selected via the PC utility software (USW).
For selection of values, see the Designer’s Reference Handbook.
3.4 Menu structure
The display includes two menu systems which can be used without password entry:
View menu system:
This is the commonly used menu system. 15 windows are configurable and can be entered by us-
ing the arrow push-buttons.
Setup menu system (not commonly used by the operator):
This menu system is used for setting up the unit, and if the operator needs detailed information
that is not available in the view menu system.
Changing of parameter settings is password-protected.
3.4.1 Entry window
When the unit is powered up, an entry window appears. The entry window is the turning point in the menu
structure and as such the gateway to the other menus. It can always be reached by pushing the BACK push-
button three times.
The event and alarm list will appear at power up if an alarm is present.

3.6 Mode menu
If the MODE push-button is pushed, a selection of possible running modes appears in the fourth display line.
Using the and push-buttons moves the cursor, and the appropriate mode can be selected by pressing
the SEL button:
Mode Description
SEMI - The display push-buttons (START, STOP, GB ON, GB OFF) are active and can be used by
the operator.
- The regulators are also active, i.e. 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 unit will start the generator, carry out the test sequence (predefined 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 predefined value; Full test: Transfer the load to the
genset and open the MB.
AUTO - The unit will automatically carry out the control type selected (AMF, fixed power, etc.).
- The display control push-buttons (START, STOP, GB ON, GB OFF) are disabled.
- If the selected running mode is fixed power, mains power export, load takeover or island, tim-
er start/stop (week watch) or binary input, then start/stop can be used.
MAN - The display push-buttons (START, STOP) are active and can be used by the operator.
- The regulators are not active, i.e. 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 unit will not be able to start. BLOCK mode can be selected during standstill and the
password is needed to exit BLOCK mode. If the BLOCK mode is selected while the genset is
running, the mode will have no effect until the genset is stopped. To select another mode af-
ter the BLOCK mode, the password must be entered.

4. Alarm handling and log list
4.1 Alarm handling
When an alarm occurs, the unit will automatically go to the alarm list for display of the alarm.
If reading of the alarms is not desired, use the BACK push-button to exit the alarm list.
If you decide to enter the alarm list later, use the INFO push-button to jump directly to the alarm list reading.
The alarm list contains both acknowledged and unacknowledged alarms provided that they are still active
(that is the alarm condition is still present). Once an alarm is acknowledged and the condition has disap-
peared, the alarm will no longer be displayed in the alarm list.
This means that if there are no alarms, the alarm list will be empty.
