Graphical display of measured values on the 3RW5 HMI High Feature

Requirements
• 3RW5 HMI High Feature from firmware version V3.0
Operating principle
The 3RW55 and 3RW55 Failsafe soft starters support graphical display of measured values.
These measured values can be presented as bar or line charts on the display of the 3RW5 HMI
High Feature.
Procedure for displaying bar charts
The following measured values can be shown in the bar chart:
• Phase current L1 (%) and (rms)
• Phase current L2 (%) and (rms)
• Phase current L3 (%) and (rms)
• Phase current average (%) and (rms)
1. Select the menu item "Monitoring > Measured values > Phase currents (%) / Phase currents
(rms) > Show bar chart".
Depending on the menu item selected, the current values of the 3 phase currents (%) or
phase currents (rms) and the average value are displayed graphically in a bar chart.
2. Use the left and right navigations keys of the 3RW5 HMI High Feature to switch the view
between Phase currents (%) and Phase currents (rms).
3. Press the ESC key to exit the bar chart view.
The example chart shows the current 3 phase currents (L1/L2/L3) and the associated average
value as a percentage. The scaling of the x-axis is 200%.

Description
The remaining cooling time of the switching element depends on the
thermal capacity of the power unit and the ambient conditions (tem‐
perature, air circulation, installation location, etc.).
The remaining switching element cooling time is stated in seconds.
The currently calculated switching element heating is continuously
compared with the previously saved switching element heating and
indicated in %.
The remaining time in seconds following a switching operation until the
motor can be switched on again.
You will find more information in chapter Switching frequency monitor‐
ing (Page 178).
