NOTE: The value for the overpressure warning can not be greater than the
value for the overpressure fault.
NOTE: Only with Speed control (pressure display): The value for the
overpressure warning/fault can not be less than the value for the
underpressure warning.
Overpressure fault: 15 bar (1500 kPa / 218 psi)
Overpressure warning: 10 bar (1000 kPa / 145 psi)
Underpressure warning: 0 bar (0 kPa / 0 psi)
Pressure Sensor C
Unlike pressure sensors A and B, the pressure sensors C are not assigned to
a motor. For this reason, the operator is shown a screen with an overview of
all sensors and their actual pressure values.
Example Fig. 4‐104: There is only one pressure sensor C1.
P SENSOR C1
To the pressure alarm parameters
NOTE: The values for warnings and faults are absolute values in Speed
control mode with the option Pressure display (Fig. 4‐102). With the option
Pressure control , the values are differential values for sensors A and B
(Fig. 4‐103)and absolute values for the sensors C (Fig. 4‐102).
