o Horn
9 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).
o Auxiliary emergency stop button
o Power detection
9 Used for starting the generating set in automatic mode following:
A loss of power (one or more phases)
A decrease or increase in mains voltage (time and threshold-adjustable)
A direction of rotation check
o Differential protection
9 This may be provided either:
By a "vigi" unit connected directly to the circuit breaker (current delay and threshold)
Or by a time and threshold-adjustable differential relay.
o Protection against insulation faults
o Used on "IT" systems, unearthed or impedance-earthed neutral, and set up by adding a "PIM" (Permanent
Insulation Monitor)
o Automatic filling
o Used to automatically top up the fuel in the daily storage tank. The fuel pump option comprises a control module
connected to the thermal-magnetic circuit breaker for protecting the engine.
o 600 Volts
o This option is used mainly for the Canadian market (600 Volts). A three-phase transformer is positioned
between the alternator and the Nexys database measurement input. When performing the 600 Volt configuration,
a weighting coefficient is applied to the voltage measurement.
3. Use
The command / control module supports two possible modes:
¾ manual mode
¾ automatic mode.
