Motor (contd.)
Pressure Sensor A
Two pressure sensors (A and B) can be assigned per pump (Refer to
Pressure Sensor Setup Fig. 4-48). The measured pressures are shown in
the motor screen (Fig. 4-50, M1).
NOTE: The values for warnings and faults are absolute values in Speed
control mode with the option Pressure display. With the option Pressure
control, the values are differential values for sensors A and B and absolute
values for the sensors C.

NOTE: The overpressure value for the warning can not be greater than the
value for the fault.
NOTE: The overpressure value for the warning/fault can not be less than
the value for the underpressure warning.
Overpressure fault: 15 bar (218 psi)
Overpressure warning: 10 bar (145 psi)
Underpressure warning: 0 bar (0 psi)
