The voltage value is compared with a threshold value programmable, giving an alarm when exceeded.
Current value is processed to calculate the RMS amplitude and the total harmonic distortion THD: when a maximum short-circuit and current distortion threshold is exceeded, an alarm output is generated.
The temperature value is monitored to activate cooling devices (fan, etc…) when a programmable pre-alarm threshold is exceeded and to produce an alarm if a programmable maximum value is exceeded.
All measurements and alarms are displayed on the front panel display. Working parameters setup is accomplished using 4 functional keys.
Small size (DIN 96×96 mm) and low cost make CPM ideal to use in all industrial and civil electrical plants.

In temperature alarm conditions, the FAN relay is opened.
The alarm integral time can be cleared manually by pressing the RESET/PHASE key (for 5 seconds) or automatically after that a time longer than the trigger time is elapsed without alarm occurrences.
Parameter / Led
Use the ▲MAX and ▼MIN keys to modify the displayed parameter and the SCROLL key to pass to next parameter. By pressing the RESET/PHASE key for 5 seconds, it’s possible to force the current value as default.
To exit from programming mode, wait 10 seconds without pressing any button: the device automatically switches to measure mode.
