Up to 4 setpoint alarms,
2 as standard with SPDT relay contact outputs,
2 more on option, with electronic switch outputs.
Each individually programmable for its speed setpoint, its hysteresis performance, its state at starter condition, power failure, and at a sensor input failure.
*
Measurement uses the advantageous principle of quartz controlled pulse distance evaluation, automatically extended over a programmable minimum period of time. The ideal combination of fast response and averaging of measurements, as appropriate for the application.
