Simple power-monitoring function and operating days alarm Simple power-monitoring function • By connecting a current transformer (to be prepared separately), electric power consumption of a heater can be displayed. (Electric power is calculated with the fixed voltage value.) • Current detector (CT) is to be prepared separately • Current detection range: 1 A to 100 A
Operating days alarm • Displays the operating days and activates alarm output (optional) when it exceeds the setpoint. • This function is useful for preventive maintenance because it let you know the appropriate time for maintenance work.
