The field-proven SIRIUS monitoring relays for electrical and mechanical quantities enable constant monitoring of all important characteristic quantities that provide information about the functional capability of a plant. Both sudden disturbances and gradual changes, which may indicate the need for maintenance, are detected. Through relay outputs, the monitoring relays enable direct disconnection of the affected system components as well as alarming (e.g. by switching a warning lamp). To respond flexibly to brief faults such as voltage dips or load changes, the monitoring relays have settable delay times. This avoids unnecessary alarms and disconnections while enhancing plant availability.
The individual 3UG4 monitoring relays offer the following functions in various combinations:
The SIRIUS 3UG4 monitoring relays monitor the most diverse electrical and mechanical quantities in the feeder, and provide reliable protection against damage in the plant. For this purpose, the SIRIUS monitoring relays offer freely parameterizable limit values and diverse options for adapting to the respective task, and in the event of a fault, they provide clear diagnostics information.
The digitally adjustable products also display the current measured values direct on the device. This not only facilitates the display of valuable plant status information during operation, it also enables adjustment of the monitored limit values in accordance with the actual conditions.
The positive result: More selective avoidance of production faults – sustained increases in availability and productivity.
The 3UG4 monitoring relays are available for the following applications:
