Pico System Settings
You can modify system settings on Pico models equipped with
keypad and an LCD display, or by using PicoSoft (v2.1 and higher).
Password Protection
The Pico circuit diagram, function relay settings, and system
parameters can be password protected.
In this case, the password consists of a value between 0001 and 9999.
The number combination 0000 is used to delete a password.
Password protection blocks access to the circuit diagram menu and
System menu and thus offers protection against the following:
• unauthorized modification of the circuit diagram
• modification of function relay parameters via the circuit diagram
• transfer of a circuit diagram from and to the memory module
• changing between operating modes Run or Stop.
• settings of the real-time clock
• communication with individual device
• switching off the password delete function
• modification of system parameters
– set new password
– Debounce (input delay) ON/OFF
– P buttons ON/OFF
– menu language selection
The password does NOT offer protection against access to the
parameters of function relays marked with ’+’.
IMPORTANT
Only parameters marked with ’-’ are
password-protected. Parameters marked with ’+’ can
still be modified via the PARAMETER menu.
