Procedure
1. Make sure that a micro SD card is in the slot of the 3RW5 HMI High Feature.
2. Set the "Ex application" parameter and the corresponding parameters in the "Ex relevant
parameters" menu.
3. Exit the "Ex operation" menu with the ESC key.
A popup window appears in the display of the 3RW5 HMI High Feature. The LEDs on the
3RW55 and 3RW55 Failsafe soft starters indicate that the device is waiting for con󹪝rmation
of the Ex-relevant parameters. You will 󹪝nd more information in chapter LED display
(Page 247).
4. Con󹪝rm the menu entry "Load Ex parameterization to micro SD card" with the OK key.
The 3RW5 HMI High Feature generates a text 󹪝le in English ("txt" 󹪝le format) in which the new
parameter settings are logged. This text 󹪝le is stored on the micro SD card in the 3RW5 HMI
High Feature.
5. Check the parameter settings in the text 󹪝le, e.g. on a PC.
– If the parameter settings are correct, con󹪝rm the menu item "Con󹪝rm Ex parameters" on
the 3RW5 HMI High Feature with the OK key. The parameters will be saved.
– If the parameter settings contain any errors, con󹪝rm the menu item "Discard Ex
parameters" on the 3RW5 HMI High Feature with the OK key and set the parameters again.
6. Check con󹪝rmation of the Ex-relevant parameters on the device LEDs on the 3RW55 or
3RW55 Failsafe soft starter. You will 󹪝nd more information in chapter LED display (Page 247).
