Definition of Ratings & Reference Conditions
Prime Power (PRP) is the nominal output continuously available, where the average load (variable) does not exceed 75% of the
prime power rating. 10% overload is available for a maximum of 1 hour in 12 hours of operation.
Standby Power (ESP) is the maximum output available, for up to 500 hours per year, where the average load does not exceed 85%
of the standby power rating. No overload is available.
Standard Reference Conditions: air inlet temperature 25°C (77°F), barometric pressure 100kPa, [100m (328ft) altitude], 30%
relative humidity.
Note: The above ratings may be subject to derate at different operating conditions. Please see the Derate Guidelines on the
Broadcrown website.
All power ratings and reference conditions in accordance with ISO 8528-1 and ISO 3046-1.

STANDARD CONTROL SYSTEM BC 7310 Digital Auto Start
The standard control system for this model is BC 7310 (photo), based on the Deep
Sea Electronics DSE7310 Digital Auto Start controller.
This provides for the manual and automatic remote start of the generator, together
with full control and protection of the engine via the ECU. LCD digital display of :
▪ Coolant temperature with high temperature alarm and shutdown
▪ Oil pressure with low pressure alarm and shutdown
▪ Oil temperature, engine operating hours, battery charge volts and amps
▪ Volts, with Under/Over Volts protection
▪ Amps, with Over Current protection
▪ Frequency, kW, kVA, Power Factor
Also featuring :
▪ Full RS485 Telemetry implementation
▪ Automatic cool-down timer function
▪ Emergency Stop button
▪ Ample auxiliary inputs/outputs for optional features
▪ Optional (shown) - battery charger and door mounted illuminated switch.
CONTROL SYSTEM OPTIONS
The BC 7320 control system (just the DSE7320 module is shown here) has an identical feature
set to the BC 7310 but with the addition of full AMF functionality with integrated mains
monitoring.
Finally, BC 8610 & BC 8620 control systems provide the same features as
BC 7310 & BC 7320 respectively, plus :
▪ BC 8610 - Set-to-Set Synchronisation
▪ BC 8620 - Single Set-to-Mains Supply Synchronisation with
integrated mains monitoring
For Multi Set-to-Mains synchronisation, each set requires BC 8610 with the addition
of one mains monitoring panel BC 8660 (not illustrated).
See the Synchronisation Guidelines for further details.
