In kW down operation, the 2301E-J can perform the following operations:
– Run in parallel with the mains. (Load level or speed reference preset or manually adjusted to the desired level via discrete or analogue inputs).
– Parallel operation with other engine generator sets. (Manual adjustment of the speed reference to the desired level via discrete or analogue inputs).
– Single engine genset operation. (Manual adjustment of the speed reference to the desired level via discrete or analogue inputs).
– In reduced speed operation, the 2301E-J can perform the following operations:
– Run in parallel with the power supply. (Manually adjust the load level or RPM reference to the desired level via the discrete inputs or analogue inputs).
– Operate in parallel with other engine generator sets. (Manually adjust the load level to the desired level via the discrete inputs or analogue inputs).
– Single engine genset operation. (Manually adjust the speed reference to the desired level via the discrete or analogue inputs).
The 2301E-J system has the following inputs/outputs:
– 1 kW sensing input, including 3-phase PT inputs and 3-phase CT inputs
– 1 speed sensing input (MPU input)
– 2 analogue inputs for (4-20 mA) current signals or (±2.5 V, 1-5 V, or 0-5 V) voltage signals
– 8 discrete inputs
– 1 actuator drive circuit
– 1 analogue 4-20 mA output (optionally with signal display via this output)
– 4 discrete outputs (low-side actuator; max. 200 mA potting current)
– 2 serial ports (RS-232 and RS-422)
The 2301E-J system has the following features:
– Speed control: isochronous operation, kW down operation, speed down operation
– Load control: isochronous load sharing, isochronous base load, soft loading/unloading
– Equal speed/deceleration operation transfer function when generator is loaded
– Fuel Limiters: Start Fuel Limiter, Torque Fuel Limiter, Manifold Fuel Limiter, Maximum Fuel Limiter
Equipment required to operate the engine generator set with the 2301E-J:
– 2301E-J Controls
– 24 Volt DC Power Supply
– Speed sensing device (MPU, etc.)
– Actuator to drive fuel rack or gas valve (proportional)
– CT and PT for generator kW sensing or analogue kW signals
The 2301E-J requires a nominal 24 Vdc voltage source. (Supply voltage range is 18 to 36 volts DC).
The controller is mounted in a sheet metal chassis and consists of a printed circuit board.
Functions
The 2301E-J has speed control, load control, equal dcs-sis.com speed/no load transfer, and fuel limiter functions.
Speed Control Function
– Rated speed range of 400-3600 rpm
– Constant speed speed control
– kW Reduced speed control
– Simple derating control is selectable (when selected, the load control function is not available)
– Idling/rated speed switching by discrete input signal
– Speed reference up/down using discrete input signals
– Fast synchronisation using analogue speed bias signal from synchroniser
– (Optional) Speed reference manipulation function using remote analogue signal
– Single point control gain setting (optional)
– A control gain curve consisting of 5 points with 4 ramps can be mapped to the engine to change gain under various operating conditions.
– Dual power function to switch control power according to engine load
