Himoinsa M6 - Stopping the Motor; M6 Control Unit Operating Modes; Stop Mode; Manual Mode

OPERATION| PAG. 11
4.3 OPERATING MODES
The M6 control unit is turned on by turning the key on the control panel to either
the “MAN” or “AUT”O position. Controller checks leds by setting on sequentially
during power on.
4.3.1 STOP MODE (STOP)
By selecting the “STOP mod”e, the control unit orders the generator set motor to
stop in a controlled manner if it is in operation and, after checking that it has
stopped, proceeds to switch off the control unit.
4.3.2 MANUAL MODE (MAN)
Selecting “MAN mode”, starting and stopping the generator set is controlled via
the START button on the control panel. By pressing “START” the motor is ordered
to start immediately if the motor is stopped, indicated by the Motor running LED
not being lit.
If “START button” is pressed while the genset is in operation, indicated by the
Motor running LED lit at the front of the M6 control unit, the genset is stopped by
disconnecting the genset load via the deactivation of the contactor output (CON)
of the control unit and proceeding to engage the cooling process indicated by the
Cooling and stop LED lit at the front of the M6 control unit.
If “START button” is pressed when the motor is in the process of cooling, indicat-
ed by the Cooling and stop LED at the front of the M6 control unit, an immediate
stop is carried out, cancelling the motor cooling process.
4.3.3 AUTOMATIC MODE (AUTO)
When selecting “AUTO mode”, the starting and stopping of the generator set is
controlled by means of the external start input via voltage free contact (LT) of the
M6 control unit.
With the closure of the voltage free contact, the control unit commands the
generator set motor to start.
With the opening of the voltage free contact, the control unit commands the
generator set motor to stop with cooling.
The congurable stop output (PC) of the control unit is used in motors for PR/
PULL control (parameter 15 value 3) to energize the motor solenoid by activating
a pulse for a duration of 1 second during the start process.
• Generator load activation: Once any motor starting condition has
been detected, the control unit waits for a set time (parameter 5) for
the activation of charging through the contactor output (CON) of the
control unit.
4.2 STOPPING THE MOTOR
With the motor started, when stopping the motor, the M6 control unit proceeds to
perform the following operations:
• Deactivating charging. The M6 control unit deactivates the contactor
output (CON) to release the charging of the generator set.
• Cooling the motor. Motor will continue running without load for a
programmable. If any alarm is detected, the M6 control unit performs
an immediate stop without cooling the motor.
• Motor stop. After the motor cooling time has passed, the IGNITION
output (PD) of the M6 control unit is deactivated and, depending on
the motor conguration (parameter 15) the following occurs:
• Deactivation of the CONFIGURABLE STOP output (PC) for motor
congurations PR/PD and PE/PD (parameter 15 value 0 and 2).
• Activation of the CONFIGURABLE STOP output (PC) for motor
congurations PR/PE (parameter 15 value 1) for a congurable
time (parameter 7).
• Activation of the PREHEATING output (PR) for motor
congurations PE/PD (parameter 15 value 2) for a congurable
time (parameter 7).
• Motor is stopped if no start condition is detected. The following start
condition can be selected:
• Generator frequency (parameter 16 value 0). The motor is
considered stopped when the generator frequency is zero.
• Motor speed (parameter 16 value 1). The motor is considered
stopped when the motor speed is zero.
• Low Oil Pressure Input (parameter 22). The motor is considered
stopped when the motor oil pressure switch connected to the
low oil pressure input (BPA) is closed.
• Battery charging alternator voltage (parameter 21 value 1).
The motor is considered stopped when the battery charging
alternator voltage is less than a certain voltage (60% of the
battery voltage).
