Supplement to Operating Manual, 08/2010, A5E03006584020A-01
NOTICE
Note on step 2: Termination of power-up by pressing the "SET" button:
While the CP is powering up, do not press the "SET" button, if you press the "SET" button
the CP will switch to a special internal state: An LED running light display is activated (LED
"SF" - "PWR" - "APF" - "CER" - "AUP" - "CM"). The CP cannot operate normally in this
special state.
To cancel this special state, the power supply to the SIMATIC station must be switched off.
NOTICE
Note on step 7 (storing the setting):
If you want to cancel the setting of the voltage monitoring without saving it, you must switch
off the power supply to the SIMATIC station instead of performing step 7.
The CP will be ready to run (normal operation) immediately after powering up.
NOTICE
Note on steps 4 to 8:
Perform steps 4 to 8 only if you want to change the current setting of the voltage
monitoring.
