Running Mode Description
Manual Mode
The unit can be operated in manual mode (MAN). Manual means that the unit will not
initiate any sequences automatically, as is the case with the auto mode. It will only
initiate sequences, if external signals are given.
An external signal may be given in three ways:
1. Start and Stop and MAN push-buttons on the display are used
2. Digital inputs are used
3. Modbus command at service port or RS 485
NOTE: The standard EMS-GC10 is only equipped with a limited
number of digital inputs, please see "Digital inputs" in this
document for additional information about availability.
The following sequences can be activated in manual mode:
Command Description Comment
Start The start sequence is initiated and continues until the genset starts or
the maximum number of start attempts has been reached. First start: include
