    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.

    2.2 About the guidelines 2.2.1 General purpose This document includes general guidelines for commissioning of DEIF’s Multi-line 2 units. It mainly includes instructions for settings, governor, AVR and protections check and unit adjustment. The general purpose of the document is to supply general guidelines to be used in the commissioning of the Multi-line 2.

    (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.

  • Page 14: Speed Droop

    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.

    (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.

  • Page 18: Voltage Range

    +/-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.
