6.20 RRCR external set point control
The grid can use a Radio Ripple Control Receiver (RRCR) for load management. The AGC can use the RRCR signals for power
and reactive power regulation.
You can use four binary inputs (from an external RRCR) to configure 16 signal combinations. Each of the 16 signal combinations
can used for a set point for Power, and a set point for Reactive Power or cos phi.
You can also make combined set points, for example, Power and Reactive Power, using the same inputs.
For feedback to the RRCR, you can use four relay outputs to configure 16 signal combinations. This feedback can only be used to
represent the Power set point.
INFO
As an alternative to RRCR, the controller can use Modbus or analogue inputs for load management.
6.20.1 RRCR configuration
Use the Utility Software to configure the controller response to RRCR signals.
Configure the inputs in M-Logic
Use M-Logic to define the four binary inputs. All four inputs must be defined for RRCR to work. Select the inputs under Output,
Power Limit Inputs, Power Limit Input [01 to 04].
