Configuring the current limits on your ZUBR I25 Current Control Relay is straightforward. Here's how:
- Main Current Limit (I1): This is the primary current threshold. The factory default is 10A. To view and adjust this, use the '+' or '-' buttons. The displayed value will flash, indicating it can be changed using these buttons.
- Minimal (I0) and Additional (I2) Current Limits: The Main Current Limit (I1) should always be set within the range defined by the Minimal (I0) and Additional (I2) limits. Ensure I1 is not set below I0 or above I2.
- Navigating the Function Menu: Use the center button to navigate through the menu options. Use the '+' and '-' buttons to modify the parameters. The parameter will begin flashing after the first button press, and the setting will be changed after the second press.
- Example Scenario (Motor Protection): To protect an electric motor, configure I1 to match the current draw under maximum load conditions. Adjust the switch-off delay (toF) to accommodate the operating time at maximum load. Set the Additional Current Limit (I2) to the motor's overload current and the response time (t2) to limit overload duration.
- Reset to Factory Settings: To restore the ZUBR I25 Current Control Relay to its original factory settings, press and hold all three buttons simultaneously for over 12 seconds until "dEF" appears on the display. Release the buttons, and the device will reset and reboot.
Following these steps will help you effectively set the current limits on your ZUBR I25 Current Control Relay to match your specific application's requirements, ensuring optimal performance and protection.
