Design, Functions and Operation S5-95F
2.5.4 Performing an Overall Reset on the S5-95F
You should perform an overall reset
• before you load a new control program into the S5-95F
• if the S5-95F requests an overall reset because of an error, e.g. during system initialization. You
are requested to perform an overall reset when the yellow error LED flashes regularly.
The S5-95F offers you three different ways of performing an overall reset:
• Overall reset via programmer
• Manual reset
• Automatic reset
Overall Reset via Programmer
You can select the overall reset function from the programmer's menu line (refer to the programmer
manual).
Please note that an overall reset via the programmer does not delete all data in both subunits. The
following data is retained:
• Programmer bus number
• Clock data of the integral real-time clock
• Internal data for system protection (e.g. safety procedure after power failure)
Manual Reset
With a manual reset, the complete data in both subunits is deleted.
To perform a manual reset, you should observe the following
Set both RUN/STOP switches to the STOP position
Set both ON/OFF switches to "0"
Remove batteries from both basic units
Set both ON/OFF switches to "I"
Insert the batteries in both basic units
Switch system to RUN mode
Safety Note
For reasons of electromagnetic compatibility, the ESD protective measures (see
Appendix D) must be observed when handling batteries.
