3.1 OUTPUTS
3.1.1 PREHEATING OUTPUT (PR)
The preheating output (PR) of the M6 control unit is a high power shortable out-
put (40 A) which regulates the heating process of the motor’s spark plugs during
the starting process. The activation time of the preheating output can be set
(parameter 4). The preheating output can also be used to control stopping due to
the excitation of motors which use PE/PS type control (parameter 15 value 2).
3.1.2 CONTACTOR ACTIVATION OUTPUT (CON)
The contactor output (CON) activates a programmable time (parameter 5) after
detecting the motor is running in order to ensure stabilisation of the motor before
enabling the charging of the generator set.
3.1.3 EXCITATION OUTPUT OF THE BATTERY CHARGE ALTERNATOR (D+)
The battery charge alternator excitation output (D+) of the M6 control unit is
responsible for driving the battery charge alternator during the starting process
via a starting pulse at a programmable time interval (parameter 14).
3.1.4 ALARM OUTPUT (AL)
The M6 control unit activates the alarm output (AL) upon the detection of any
active error and remains active until the system has been reset by pressing the
RESET key. Furthermore, the M6 control unit also activates the alarm output (AL)
before starting the motor in automatic operation mode by means of the external
start via voltfree contact (LT).
