Usage Scenario
Water Tank Level and Pump Automation
Locally manage pump and alarm relays based on tank level contacts.
- • Lower and upper level input
- • Pump contactor control
- • Overflow alarm
- • Operation record
Controlled filling with level information
The tank filling process can be managed by connecting lower and upper level switches to digital inputs. The pump is started at the lower level, stopped at the upper level and an alarm is generated in unexpected combinations.
Pump safety
Motor power should not be passed directly through the board relay; Appropriate contactors and motor protection elements must be used. Dry running, phase failure and mechanical protections must be supported by independent circuits.
