EMERGENCY DEVICE
Pre-arrangement for the external emergency command enabled in all operational modes with immediate stoppage of the motor, opening
of the generator contact maker and triggering of the alarm.
The emergency device not only controls the control software of the circuit board but is also equipped with an electro-mechanical circuit
that totally ensures the stoppage of the unit and the opening of the generator contact maker.
WARNING
The command is double, the NO contact of the emergency push button is required to ensure the immediate opening of the
generator contact maker even in the case of an anomaly in the electronics. In fact to ensure the emergency power supply even
in extreme cases the contact that commands the mains and generator contact makers (CG-CR) is normally closed (NC),
therefore if the contact maker is to be opened, the command relay must be powered. The motor stoppage on the other hand is
ensured by the NC contact (positive safety), which disconnects the power supply from the motor even if the circuit is
disconnected or in the case of an anomaly in the electronics (as per standard).
Other operating solutions can be applied to suit the overall design.
REMOTE SWITCHING OF THE MAINS/GENERATOR
Switching with tetrapolar contact makers of adequate capacity for the power of the unit, mechanically and electrically interlocked and
scaled in AC1 in compliance with standard ISO DIS 8528-4 ;
Switching is controlled directly by the RG 42-43-44 and RR 37-38-39 relays built in the MP02 power module, which by means of
contacts free from voltages and protected by fuses directly control switching that can be carried out using, remote control switches,
motorised commutators or motorised switches.
The CG and CR command contacts are normally closed to allow the command circuits, in the case of particular anomalies, to force the
closing of the mains contact maker by simply removing fuse F1 from the MP02 unit and disconnecting the fuse on the battery charger.
OPERATING STATUS
A page on the display has been set aside to show the unit’s status, to facilitate use of the
generator. This page shows all status indications such as: automatic test, cut-out, forced
starting, remote controlled, pilot generator, standby generator, clock to be set, etc.
These status indications allow the operator to know the status of the unit, and what to do. For example:
a) clock to be set = the battery has been disconnected and the clock must be reset as some operations need to use the clock;
b) cut-out = Stop command, the generator cannot react automatically and can only be controlled manually;
c) forced start = the generator is controlled by forced power supply, and can only be operated manually.
SERVICE REQUIRED / STOP DUE TO TIME EXPIRED
When the working hours before the next service are entered the alarm state is activated without affecting the operation of the unit, and
the display will read “SERVICE REQUIRED”.
The hours run are zeroed during servicing by going into the COMPLETED section of the Misc.
Settings Menu, and pressing RESET.
If the SERVICE hours field is set at 0000 this function is excluded.
CUSTOMISATION
This page can only be seen if programmed. It has two lines, the first can be used to enter a name
of up to 16 characters, and the second for a telephone number of up to 16 digits.
