2.13- Function description
BOARD IN RESET
If it is pressed, it switches on the RESET led and switches off eventual MAN, AUT or TEST leds. If the generator is in running, the load is
disconnected and the stop phase begins (without cooling)
No function of the generator can be executed.
Reset all alarms (if the cause doesn’t continue)
It is possible to read the measurements or the current time on the display
BOARD IN MANUAL (MAN)
If it is pressed, it switches on the MAN led and switches off eventual RESET, AUT or TEST leds.
If the generator was in AUT mode, the state of the generator and the remote control switch is maintained.
By pressing the START pushbutton the start cycle begins.
By pressing the STOP pushbutton the stop phase begins.
The state of the remote control switches never changes automatically during the stop and start phases, but their change over is however
possible by pressing the relative MAINS and GEN pushbuttons. In manual mode the ‘’remote start and stop’’ inputs are ignored. It is
necessary to press RESET or AUT to exit from the manual mode.
BOARD IN AUTOMATIC (AUT)
If it is pressed, it switches on the AUT led and switches off the eventual MAN or RESET leds.
Control of the mains voltage: if the net is included between P7.01 and P7.02 “Mains voltage presence” is switched on and the load is
changed over.
If the mains voltage is greater than P7.02 or smaller than P7.01, for a longer time than P7.03, the led “Mains voltage presence” switches off
and the starting phase begins.
If after the starting phase, the generator voltage is greater than P8.01, the led “Generator voltage presence” switches on.
If the generator voltage remains within the limits for a time longer than P8.04, the network remote control switch (signalled by the switching off
of the led “network remote control switch state”) opens and after the P5.01 time, the generator remote control switch (signalled by the
switching on of the led “generator remote control switch state”) closes.
If the generator voltage exits from the P8.01 and P8.02 limits, for a time longer than P8.03, the generator remote control switch opens and the
stop phase begins.
If the mains voltage comes again within the limits for a time longer than P7.04, the generator remote control switch opens and after the time of
P5.01 the network remote control switch closes and the stop phase with cooling begins.
When the generator remote control switch is closed, the display visualizes the generator voltage and switches on the “V GEN” led.
When the network remote control switch is closed, the display visualizes the mains voltage and the led “V MAINS” switches on.
In automatic mode, the START and STOP pushbuttons are ignored as well as the MAINS and GEN change over pushbuttons.
When the generator is running, during whichever type of operation, it is possible to stop it pressing the RESET.
Every time the generator is stopped, also because of an alarm, the load is disconnected.
AUTOMATIC TEST (TEST)
It can only be enabled in automatic mode
If it is pressed for more than 5sec, the display visualizes “ON” (enabled)
If it is released and pressed for more than 5 sec, the display visualizes “OFF”
If it is enabled, it waits for the time U.01 and the time U.03 and then it switches on the siren exit for 3sec, it waits for 3sec and then the start
phase begins.
After the engine start-up, it waits for U.02 and then the stop phase begins; the test happens with or without load as per U.04)
If the mains voltage exits from the limits during the test, the load is changed over on the generator; the generator remains operating also at
the end of the test until the network has been restored.
If the generator is in automatic mode and it is already running, the test phase is ignored.
2.14- Function steps
Starting
It closes the ‘’start-up’’ 64 output, it closes the 65 solenoid valve output, then until P2.02 or P2.03 “started engine” threshold is exceeded and for the
maximum time of P2.07.
If P2.07 is exceeded, wait for P2.08 and repeat the procedure. The cycle goes on until the “started engine” threshold is exceeded and/or the maximum
limit of attempts equal to P2.06.
During the start phase all protections of the group 4 are ignored as well as all alarms of oil minimum pressure and group minimum voltage.
When the ‘’started engine” threshold is exceeded, the “Running engine” led flashes.
Wait for P2.10 and restore the protections; when the protections are enabled the led “running engine” remains switched on with a fixed light.
- Glow plugs: before every start-up, the output 6.3 is closed for a P2.05 time (if enabled)
- Air (starter): during the start-up, if the head thermostat input is closed, the 6.3 output is closed for a P2.11 max. time and not over P2.12 (if enabled)
- Head thermostat: it inhibits the working of the air starter if the engine is warm
- EV (solenoid valve): it closes before the start phase and it reopens between the various attempts of start-up and remains always closed until the stop.
- Decelerator: after the start-up, if enabled, it waits for the overcoming of P8.01, it closes the 5.3 – 5.4 output for a P3.02 time so as to avoid that the
cold engine exceeds a certain speed (rpm). During this deceleration phase, the “electrical” alarms are inhibited (voltage, frequency)
If before a start-up, the engine is detected in running, the start-up is not allowed.
Stopping
If enabled, the cooling phase begins (the load is switch off) for a P3.03 time.
