The following example is intended to illustrate the connection and configuration of a (radio) ripple control receiver.
Example:
A radio ripple control receiver with 4 potential-free normally open contacts (NO) should regulate the active power of the system in the following stages:
- 100%
- 60%
- 30%
- 0%
Wiring the ripple control receiver to the blue'Log
The 4 potential-free normally open contacts are connected to the 4 digital (DI 1-4) inputs of the blue'Log.
Configuring the active power control in the blue'Log
Log in to the blue'Log web interface and go to Power Control -> Active Power -> Basic Settings.
Select Value Pvar DI as the method for specifying the setpoint:
After selecting PvarDI (or the gear icon), the following input mask appears:
- Here you can specify whether the inputs are switched as pulses or permanently. You can find this information in the description of the ripple control receiver.
- Specify the inputs required for control. By default, all 4 digital inputs are listed. If you need fewer than 4 inputs, you can remove them using the trash can symbol.
- Some network operators require an acknowledgement of the input signals, this can be activated using the Acknowledgement menu item. By default, the acknowledgements are output at the 4 digital outputs (DO 1-4) of the blue'Log. Advanced configuration options are available for this.
- Then switch to the Define setpoint tab
- Set the inputs according to their occupancy
- Assign a corresponding setpoint to each input.
- Then confirm with OK, the setup is complete.
After configuration is done, please get sure to:
- Activate Power Control
- Save Settings
Please check if the inputs are working properly
You can also simulate this step by bridging the corresponding inputs (DI 1-4) with GND and checking if the corresponding setpoint value is used on the Power Control tab.
