Pressure Sensor A / Pressure Sensor B
Two pressure sensors (A and B) can be assigned per pump (Refer to
Pressure Sensor Setup Fig. 4-77). The measured pressures are displayed
in the scan line of the starting screen and in the motor screen (Fig. M1).
NOTE: The values for warnings and faults are absolute values in Speed
control mode with the option Pressure display (Fig. 4-96). With the option
Pressure control, the values are differential values for sensors A and B
(Fig. 4-97)and absolute values for the sensors C (Fig. 4-96).
