2.1.2 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.
2.1.3 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.

4. Settings
4.1 Settings check
4.1.1 Settings
It is necessary to perform a settings check. This is done by following these five individual steps:
1. Check and adjust the nominal settings.
2. Check and adjust the alarm settings.
3. Check and adjust the function control settings.
4. Check and adjust the speed controller settings.
5. Check and adjust the voltage controller settings.
The above-mentioned settings must be checked and adjusted prior to the initial starting of the genset.
The settings can be adjusted either through the display or through the PC utility software. For
navigating in the menus, see the Operator’s Manual.
4.1.2 Nominal values
The nominal values of the Multi-line 2 are adjusted in the general part of the system setup menu.
In the PC utility software, it is presented as illustrated on the above screen dump. The correct values are sup-
plied by the switchboard manufacturer.

5. Governor check
5.1 Instructions
5.1.1 Instructions
Even if the engine manufacturer has adjusted the governor, it is necessary to carry out the following adjust-
ments to be sure that the Multi-line 2 can successfully operate with the speed governor.
The governor should be tuned in according to the governor/engine manufacturer’s instructions. It is important
that the engine is able to run smoothly and without hunting, before the control function of the Multi-line 2 is
activated.
5.2 Speed setting
5.2.1 Speed setting
An initial speed setting must be made.
The speed setting procedure is depending on the interfacing.
5.2.2 Relay output
● Disable the outputs from the Multi-line 2.
● Run the generator with no load (open generator breaker).
● Adjust the frequency (on the speed governor) to be base frequency (50 or 60 Hz).
5.2.3 Analogue output
The analogue output is a +/-25 mA or 0-20 mA (depending on option) signal which in most cases must be
converted into a voltage using a resistor across the terminals (150 Ω gives 3V DC at 20 mA, etc).
The AGC 200 series has no analogue outputs. If analogue outputs are needed, the IOM 200 series external
interface unit must be used.
Given the fact that especially the governors are sensitive to the external circuit impedance, it is essential to
carry out the initial setting of speed governor while the Multi-line 2 is connected and the control function disa-
bled.
Putting the Multi-line 2 in manual operation, (AGC 200/AGC-3/AGC-4 = MAN, PPM = switchboard control)
disables the control function. This will "disable" the control outputs, but the generator protection is still active.
If you fail to do this, you may experience control problems later on.
● Set the unit in manual operation/switchboard control.
● Reboot the unit or activate the input "reset analogue controller outputs".
● Run the generator with no load (open generator breaker).
● Set the frequency (on the speed governor) to be base frequency (50 or 60 Hz).
5.2.4 EIC, J1939
The speed setting is not possible to adjust because the proper rpm is adjusted in the ECU from the factory
side.

5.3 Speed droop
5.3.1 Speed droop
The speed governor must have a speed droop of 3-4% (speed dropping 3-4% from no load to full load, when
the Multi-line 2 is not in control). In order to ensure equal load sharing on parallel running machines, all gov-
ernors must have the same droop setting.
DEIF recommends adjusting the speed droop on the speed governor for stability purposes.
It is necessary in all cases when relay outputs for governor control is used.
When analogue interfacing is used, it is possible to operate with a speed droop adjustment of
0%, but for safety reasons it is recommended to use the speed droop adjustment.
5.4 Speed range
5.4.1 Speed range
When using the analogue interfacing, the resistor installed across the output terminals is selected to obtain
the necessary speed range. When finding the correct resistor, several aspects must be considered.
The necessary speed range must be selected, so it is possible to operate at full load. Typically, this is fNOM
+3 Hz. If the speed range is too high, the resistor size must be decreased. If the speed range is too low, the
resistor size must be increased.
The speed range must allow for the full load of the genset. If full load cannot be reached, then
the resistor size must be increased.
5.5 Terminals
5.5.1 Terminals
The governor can either be prepared for analogue interfacing or digital interfacing. When analogue interfacing
is used, a +/-25 mA or 0-20 mA signal from the Multi-line 2 is applied. This signal can be converted to the
necessary voltage level. When digital interfacing is used, two relays are used as increase/decrease outputs.
The terminals must be identified depending on the necessary interfacing. Some general examples are shown
in the following illustrations.

6. AVR check
6.1 Instructions
6.1.1 Instructions
Even if the AVR is adjusted by the genset manufacturer, it is necessary to go through the following adjust-
ments in order to be sure that the Multi-line 2 can operate with the AVR.
The AVR should be tuned in according to the AVR/generator manufacturer’s instructions. It is imperative that
the genset is able to operate smoothly, before the control function of the Multi-line 2 is activated.
6.2 Voltage setting
6.2.1 Voltage setting
An initial voltage level setting must be made.
The voltage level setting procedure is depending on the interfacing.
6.2.2 Relay output
● Disable the outputs from the Multi-line 2.
● Run the generator with no load (open generator breaker).
● Adjust the voltage (on the AVR) to be nominal voltage.
6.2.3 Analogue output
The analogue output is a +/-25 mA or 0-20 mA (depending on option) signal which in most cases has to be
converted into a voltage using a resistor across the terminals (150 Ω gives 3V DC at 20 mA etc).
The AGC 200 series has no analogue outputs. If analogue outputs are needed, the IOM 200 series external
interface unit must be used.
Given the fact that especially the AVRs are sensitive to the external circuit impedance, it is essential to carry
out the initial setting of the AVR while the Multi-line 2 is connected and the control function disabled.
Putting the Multi-line 2 in manual operation, (AGC 200/AGC-3/AGC-4 = MAN, PPM = switchboard control)
disables the control function. This will ‘disable’ the control outputs, but the generator protection is still active. If
you fail to do this, you may experience control problems later on.
● Set the unit in manual operation/switchboard control.
● Reboot the unit or activate the input "reset analogue controller outputs".
● Run the generator with no load (open generator breaker).
● Set the voltage (on the AVR) to be nominal voltage.
6.3 Voltage droop
6.3.1 Voltage droop
The AVR controls the generator voltage in a way which is comparable to the speed governor controlling the
prime mover speed.
General guidelines for commissioning
4189340703 UK
AVR check
DEIF A/S Page 17 of 25

This means that the generator AVR must have a voltage droop of 3-4% (voltage dropping 3-4% from no load
to full reactive load when the Multi-line 2 has no control). In order to ensure equal VAr sharing on parallel
running generators, all generators must have the same voltage droop setting.
6.4 Voltage range
6.4.1 Voltage range
When using the analogue interfacing, the resistor installed across the output terminals is selected to obtain
the necessary speed range. The voltage range must be defined similar to the speed range for the governor.
The voltage range must be wide enough for the voltage droop and for the full loading of the genset. A typical
value is +/-10% * UNOM. The necessary control signal level is often specified depending on the AVR type.
6.5 Terminals
6.5.1 Terminals
The AVR can either be prepared for analogue interfacing or digital interfacing. When analogue interfacing is
used, a +/-25 mA or 0-20 mA signal from the Multi-line 2 is applied. This signal can be converted to the nec-
essary voltage level. When the digital interfacing is used, two relays are used as increase/decrease outputs.
The AGC 200 series has no analogue outputs. If analogue outputs are needed, the IOM 200 series external
interface unit must be used.
The terminals must be identified depending on the necessary interfacing. Some general examples are shown
in the illustrations in the chapter "Governor check".

7. Protections
7.1 Protections check
7.1.1 Points to be considered
As a part of the commissioning, the protections should be checked.
The following points must be considered for each alarm:
● Alarm setpoint
● Alarm delay
● Relay output
● Activation
● Fail class
● Inhibits
For further information about the above-mentioned, see the Designer’s Reference Handbook.
7.1.2 Considerations
Several issues must be taken into consideration when doing the configuration of the alarms. These are e.g.
national rules and requirements, additionally installed protection equipment, required use of the protections
(trip of non-essential load, breaker tripping and engine stopping).
The switchboard manufacturer and the end customer must take these considerations.
7.1.3 Configuration of the protections
The dialogue box shows a typical alarm.
