Menu: "Monitoring > Measured values"
Operating principle
The measured values are provided by the respective device functions. All measured values
are stored in the measured value memory which is not secure against voltage failure. These
values can be read out and evaluated by the 3RW5 HMI High Feature. You can specify up to
5 measured values, which are shown on the operation display (Page 113).

chart
The phase currents are displayed as a percentage. You can monitor each phase
(L1/L2/L3) individually, or the average of all 3 phases.
These measured values can be presented graphically as bar or line graph on the
display of the 3RW5 HMI High Feature. For more information, see Chapter
Graphic display of measured values on the 3RW5 HMI High Feature (Page 147).
Phase currents (rms)
The phase currents are displayed in amperes. You can monitor each phase
(L1/L2/L3) individually, or the average of all 3 phases.
These measured values can be presented graphically as bar or line graph on the
display of the 3RW5 HMI High Feature. For more information, see Chapter
Graphic display of measured values on the 3RW5 HMI High Feature (Page 147).
Motor temperature rise [%]
The measured value shows the relative temperature rise of the motor.
Remaining motor cooling time [s]
The remaining recovery time is the minimum cooling time of the motor that must
elapse following activation of motor overload protection before the
3RW50 soft starter is once again ready for operation.
Remaining switching element cooling
time [s]
The remaining cooling time of the switching element is dependent on the thermal
capacity of the power unit and the ambient conditions (temperature, air
circulation, installation location, etc.). The remaining cooling time of the switching
element is the time that must elapse following activation of the intrinsic device
protection before the 3RW50 soft starter is once again ready for operation.
Switching element heating [%]
The currently calculated switching element heating is displayed as a percent
value of the previously saved switching element heating.
