Frequently Answers and Questions

How does the Contrel RI-R45 Insulation monitoring device work?

The RI-R45 utilizes a DC component measure signal to check the insulation resistance between the insulated line and earth. By detecting leakage current, it triggers an alarm if the insulation resistance falls below the set threshold.

What are the available reset options for the RI-R45?

You can choose between automatic or manual reset. Automatic reset happens when the insulation condition improves, while manual reset can be done using the front RESET button or an external button.

How can I adjust the trip threshold on the RI-R45?

The trip threshold can be adjusted using the dip switches on the device according to the specified resistance values. The manual provides a detailed table to guide you on setting the desired threshold.
