CONNECTIONS| PAG. 7
3. CONNECTIONS
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).

CONNECTIONS| PAG. 8
3.1.7 IGNITION (PD)
The IGNITION output (PD) is activated 500 ms after the preheating output has
been deactivated and remains active while the motor is running. The IGNITION
output (PD) is interconnected with the emergency stop input (PEM) of the control
unit.
For motors congured with the starting control mode PULL/HOLD (parameter 15
value 3), the IGNITION output (PD) is also activated during starting in the motor
preheating phase.
3.2 INPUTS
3.2.1 ALTERNATOR VOLTAGE INPUT (GEN)
The alternator voltage input is used to calculate the electrical signal frequency of
the generator (parameter 16 value 0). To do this 2-phases of the alternator are
connected between the GEN and GCOM inputs of the control unit in gensets with
more than one phase or 1 phase and the neutral of the alternator between the
GEN and GCOM inputs of the control unit in single phase gensets.
3.2.2 PICK-UP INPUT (PCK)
The pickup input is used to calculate the motor rotation speed (parameter 16
value 1). To do this, the motor pickup signal is connected to the PCK and GCOM
terminals of the control unit.
3.2.3 VOLTAGE INPUT OF THE ALTERNATOR AND PICK-UP (GCOM)
Same input for reading the alternator voltage frequency and motor speed, accord-
ing to the programming of the control unit (parameter 16). Only one of the two
signals can be wired to the terminal of the GCOM input of the M6 control unit.
3.1.5 STARTING OUTPUT (ARR)
The motor starting output (ARR) of the M6 control unit is a high power shortable
output (40 A) which activates the starter. The motor starting output (ARR)
remains active until a condition is detected while the motor is running for a pro-
grammable maximum time (parameter 3).
3.1.6 CONFIGURABLE STOP (PC)
The congurable motor stop output (PC) of the M6 control unit is a high power
shortable output (40 A) that controls the stopping of the motor and is intercon-
nected with the emergency stop input (PEM) of the control unit. The congurable
motor stop output (PC) can be congured so that it controls motors according to
four different start/stop modes (parameter 15):
•PR/PD (parameter 15 value 0): The congurable motor stop output
(PC) for motors with PR/PD control is activated 500 ms after the
preheating output has been deactivated, and remains active while the
motor is running.
•PR/PE (parameter 15 value 1): The congurable motor stop output
(PC) for motors with PR/PE control is activated during a programmable
time interval (parameter 7) when the motor stop command has been
given. In this conguration, the emergency stop input (PEM) of the
control unit must be wired to the negative terminal of the battery and
the emergency stop button must be wired to the auxiliary input of the
(AUX) alarm.
•PE/PD (parameter 15 value 2): The congurable motor stop output
(PC) for motors with PE/PD control is activated 500 ms after the
preheating output (PR) has been deactivated, which occurs when the
motor stop command has been given. This output is used to enable
the motor sensors. The preheating output (PR) of the control unit is
responsible for executing the motor stop by activating the stop by
excitation process.
•PULL/HOLD (parameter 15 value 3): The motor start control set in
PULL/HOLD mode uses the congurable output (PC) as PULL signal
(40 A) which is activated for a xed time of 1 second during starting.
The IGNITION output (PD) is used as HOLD signal (2 A) which remains
active while the motor is running.

CONNECTIONS| PAG. 9
3.2.9 EMERGENCY STOP INPUT (PEM)
Digital input to connect an emergency stop for inmediately motor stop without
cooling. The emergency stop alarm has a visual signal on the front of the M6
control unit.
3.3 USB PORT
It allows the programming of certain parameters, in addition to the reading of the
internal hour counter (total and partial) and alarm history through a PC.
3.2.4 WATER TEMPERATURE INPUT (ATA)
Input connected to the motor coolant temperature thermostat that is used to
detect a high water temperature alarm condition. The polarity of the ATA input is
congurable (parameter 23). The high motor temperature alarm has a visual sig-
nal on the front of the M6 control unit. The high motor temperature alarm causes
the motor to stop immediately
3.2.5 LOW OIL PRESSURE INPUT (BPA)
Input connected to the engine oil pressure switch, indicating to the control unit
that a low oil pressure alarm has ocurred. Polarity of the BPA input is congur-
able (parameter 24). The low oil pressure alarm has a visual signal on the front
of the M6 control unit. The low oil pressure alarm causes the motor to stop
immediately.
3.2.6 FUEL RESERVE INPUT (RC)
Input connected to the fuel tank gaug ethat is used to detect a fuel reserve
alarm condition. The polarity of the RC input is congurable (parameter 27). The
fuel reserve alarm has a visual signal on the front of the M6 control unit. The
action taken by the M6 control unit after detecting the fuel reserve alarm is pro-
grammable (parameter 18).
3.2.7 AUXILIARY ALARM INPUT (AUX)
Input connected to any sensor which tells the control unit that is used to detect a
motor auxiliary alarm condition. The polarity of the AUX input is congurable
(parameter 25). The motor auxiliary alarm has a visual signal on the front of the
M6 control unit. The auxiliary engine alarm causes an immediate stop motor.
3.2.8 ENTRADA ARRANQUE EXTERNO (LT)
Digital signal for connecting a volt-free contact forcing the starting of the genset
when the M6 control unit is in automatic mode. The polarity of the LT input is
congurable (parameter 26). The external start input has a visual signal on the
front of the M6 control unit.

OPERATION| PAG. 10
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, .

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).

OPERATION| PAG. 12
4.4 NOMINAL SPEED ADJUSTMENT
It is necessary to set up the nominal motor speed that is used for detecting over-
speed alarm and motor running condition:
1. The Overspeed LED on the M6 control unit is ashing to indicate that the
control unit has no nominal motor speed programmed.
2. Start the motor and wait for it to stabilise until it reaches its nominal speed.
3. Hold down “RESET button” for 5 seconds.
4. The Overspeed LED on the M6 control unit turns off to indicate that the
process is complete.
5. Management of the overspeed alarm is enabled (parameter 17 value 1).
6. To reset the setting to nominal speed, it is necessary to hold down “RESET
button” for 5 seconds with the motor stopped. Performing this process, over-
speed alarm management is disabled (parameter 17 value 1).
The described process is valid, both for speed detection by frecuency of generator
as per motor pick-up.
