Safeguards The following options may be added to the standard configuration: Measurements card (if the power rating of the generating set is less than 30 kVA) Connected directly to the base card, used for measuring and displaying: Electrical quantities (phase-to-neutral voltages "V"... -
Page 7: Use
Horn Connected to the "horn" output (2 fast-on connectors located on the electronic card), can be used to sound an audible warning in the event of a fault of any type. A "horn off" button may be pressed to inhibit operation of the horn (only the horn). -
Page 8: Manual Mode
3.1. Manual mode 3.1.1 Starting the generating set Check that the generating set circuit breaker has triggered. Danger connect the generating set battery. turn the key switch to the ON position (without forcing it) All of the LEDs light up for 2 seconds, to confirm that they are operating correctly. If the LEDs do not light up, check the protection fuse and replace it if necessary. -
Page 9: Stopping The Generating Set
Note: the LED flashes as soon as the START button is pressed and continues to flash until the frequency stabilises if a "measurements" card has not been inserted and until the frequency and voltage stabilise if a "measurements" card has been inserted. Following stabilisation, the LED light comes on continuously. -
Page 10: Stopping The Generating Set
3.2.2 Stopping the generating set When the power is restored (controlled by the SDMO switch), there is a time delay. After this (120 seconds), the external command disappears, the "emergency" switch is triggered and the "normal" switch is deactivated. -

4. Alarms and faults 4.1. Display Faults and alarms are displayed as follows: Faults LED (general fault) will flash whenever a fault occurs. In conjunction with this LED: The red LED lights up and remains lit (only for the emergency stop fault). If a pictogram appears on the LCD screen this represents the fault along with the SOS message. -

4.5. List of alarms associated with a pictogram Associated pictogram Low fuel level alarm: Indicates the need to fill up with fuel. Associated pictogram "Alternator charging fault" alarm indicates a problem affecting the alternator charging rate. 5. Special notes Emergency stop If the shunt on terminal block B11 is removed (control console interior), the generating set stops immediately due to an emergency stop fault. - Page 16 Low fuel level The low fuel level pictogram flashes if the low fuel level has been configured as an alarm. The low fuel level pictogram lights up and remains lit if the low fuel level has been configured as a fault. In this case, the general fault LED flashes red.
