This module is used to monitor partial loads, e.g. several heating elements connected to a 1-phase solid-state relay or contactor.

LEDs indicate failure of a partial load as well as fuse or thyristor faults. A normally-closed contact is used to signal faults or failures to a central controller.

The reference values are set automatically by triggering a teach input (remote teach). Voltage fluctuations are smoothed within a wide range and have no influence on the monitoring function.
