In this menu there are the management of some alarm. A complete list of PID-IMM alarm are in the Alarm
chapter of this manual.
Leakage Alarm: minimum pressure level that is checked during the Basic Run Mode.
If the pump reaches pressure level below the threshold (parameter “Min Press Leak Al 11032”) for time
longer than the time specified in “Leakage Al Time Out 11034” Leakage Detection alarm is triggered.
Alarm action is defined with IPA 11036 (“Leakage alarm Action”)
For a complete description of Basic Run mode see BASIC RUN Menù
Indirect Sensor Alarm (ISA): If pressure sensor is 0.1 to 10.1 V or 4 to 20 mA the drive is able to recognize
malfunctioning of pressure sensor. In the other case, this alarm detect a malfunction or a not correct wiring of
the pressure sensor.
If the torque is more than “ISA Torque Min 11040” and the pressure in lower than “ISA Press Threshold
11042” for a time more than “ISA Time Out 11044” Pressure Sensor alarm is triggered.
Parameter “ISA Alarm Enable 11046” enable this function.
