Performing an OVERALL
RESET
Regardless of whether you yourself or the system program requested
an overall reset, you perform the OVERALL RESET as follows:
•• Hold the mode selector in the OVERALL RESET position; at the
same time, switch the mode selector from STOP to RUN and once
again to STOP.
Result: the OVERALL RESET is performed, the STOP LED is lit
continuously.
•• OR: use the PG function OVERALL RESET
(If you perform an OVERALL RESET at the PG, the manual
overall reset request using the switches and selector can be
omitted. The position of the reset switch and mode selector are
then irrelevant.)
Result: the OVERALL RESET is performed. The STOP LED is
lit continuously.
Note
Once you have performed an OVERALL RESET, the only
permitted restart mode is a COLD RESTART.
