GENERAL DESCRIPTION

Generator set for automatic operation due to a grid failure, including the electrical operations panel, installed on a
bedplate. Start-up of the generator set will be carried out when a failure in the grid power supply is detected. Once
the generator set has stabilized, a signal is sent to the switching panel to switch the grid position to generator set.
When the grid power supply return is detected, a command is sent to the switching to switch to the generator set
position of the grid. The generator set shuts-down after the applicable cooling period has elapsed.

BEDPLATE

The engine-alternator set is coupled to the bedplate by means of anti-vibration shock mounts that absorb almost all the
vibrations.

The bedplate is made of a phosphate, passivated steel profile with polyester dust paint that guarantees a resistance of at
least 500 hours in a saline fog chamber in accordance with standard ASM B-117-09.

The fuel tank is integrated and joined to the bedplate using hardware, which allows disassembling it for maintenance or
replacement. It has a drainage plug, wide cleaning cover and filler connection with plug and key.

Includes level sensor with low fuel alarm signal that indicates the amount of fuel available in the tank to the electrical
panel.

Control Card

DEEP SEA control plate, DSE 7320 with grid monitor that starts-up the generator set when it detects a failure in the
electrical power supply from the grid and sends a signal to the switching panel to switch from the grid position to the
group position . Once the power supply has been re-established, it sends an order to the switching panel to transfer
the generator set power to the grid and shuts-down the generator set once it has cooled down. It also starts-up the
generator set using an external signal.
Also, control plate DSE 7320 checks a large number of parameters of the generator set which allows it to display
information, statuses and alarms. If required, it will shutdown the generator set: Due to high coolant fluid
temperature, low oil pressure, low coolant fluid level, etc.
Includes a 132x64 pixel LCD screen with lighting, 5 navigation menubuttons, independent operational mode buttons,
and alarms and status indicating LEDs.
Communications via USB, RS232, RS485, as well as DSEnet® for system upgrade. Possibility of Ethernet connection
(requires a separate module). MODBUS protocol available for client software. Completely configurable using a PC in
Windows environment and free Scada type software in real time.
Includes reading and displaying of parameters with RMS values, real time clock, events history log up to 250 events
and programming of alarms, events, start-ups and shutdowns.
Operating modes: START-UP, SHUTDOWN, AUTO, MANUAL AND TEST.
