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.
