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

• modification of system parameters

not offer protection against:

• changing between operating modes Run or Stop.

• setting the clock

• 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.

IMPORTANT

A password that was entered in Pico is transferred to the memory

module together with the circuit diagram, irrespective of whether

it was activated or not.

If this Pico circuit diagram is loaded from the memory module,

the password is also transferred to Pico and becomes activated

immediately.
