Take care to avoid inadvertently pressing the RUN/HALT key during operation
(see below)!
3.10.1
Multiple uses for the RUN/HALT key
The RUN/HALT key on the controller is used to trigger special functions:
Î
RUN/HALT
If the RUN/HALT key
is briefly pressed during operation, the controller switch
-
es to the HALT status. Pressing the key again initiates a cold start (program
restart).
Î
Controller RESET
If the RUN/HALT key is held down for between 6 and 10 seconds while the
controller is being switched on, the controller will be reset to the factory settings
(user program and configuration will be deleted).
Î
Firmware update
If the RUN/HALT key is pressed for less than 6 seconds while the controller is
being switched on, the controller stays in “boot mode”
(firmware update possible).
Operating status LED feedback for FW Update Mode
Display
The two LEDs flash at 1 Hz.
