4. OPERATION
4.1 STARTING THE MOTOR
With motor stopped, and without alarms, when starting the motor, the M6 control
unit proceeds to perform the following operations:
• Preheating of the motor. With the preheating process enabled
(parameter 19 value 1), the control unit activates the preheating
output (PR) in motors for PR/PD and PR/PE control (parameter 15
values 0 and 1) for the set time (parameter 3) with visual indication
via the LED on the front of the control unit.
• Enabling the starting of the motor. Enabling the starting of the motor
is done via the IGNITION output (PD) of the M6 control unit and the
CONFIGURABLE STOP output (PC) for motor congurations PR/PD and
PE/PD (parameter 15 value 0 and 2).
• Starting the motor (ARR). The starting output (ARR) of the M6 control
unit is activated until some of the enabled starting conditions have
been detected, for a maximum time (parameter 3):
• Generator frequency (parameter 16 value 0). The motor is
considered started when the generator frequency exceeds a
certain percentage (parameter 11) of the nominal frequency of
the genset.
• Motor speed (parameter 16 value 1). The motor is considered
started when the motor speed exceeds a certain percentage
(parameter 11) of the nominal motor speed.
• Alternator voltage (parameter 21 value 1). The motor is
considered started when a certain battery charging alternator
voltage (60% of the battery voltage) is exceeded.
Control unit waits for a time (parameter 2) before starting the motor again if no
motor running condition is detected during cranking time. Unit control activates
the STARTING FAILURE alarm led if the maximum starts attemps is exceeded.
Excitation of the battery charger is set on by the D+ output for a time (parameter
14) during motor starting process. Controller checks the battery charger voltage
after the battery charger excitation time.
The Alternator Failure alarm is activated with a visual signal via the Battery charg-
ing failure LED on the front of the control unit if a fault is detect in the battery
charging alternator, .
