6-6 Pico System Settings

The following requirements must be fulfilled for a parameter set to be displayed:

• a function relay must have been included in the circuit diagram

• the parameter set has been enabled for access, indicated by the “+” character at

the bottom right of the display.

Use the PARAMETER menu to access and modify accessible parameter sets.

Parameter sets for which access is not enabled are not displayed. Pico therefore

allows you to protect parameters with the use of a password. You can enable or

disable parameter access using the parameter “+”or “-” characters respectively in the

circuit diagram.

Use up or down arrows to scroll through the parameter

sets. The cursor must be located on the identifier of the

function relay, in this case T1.

Change the values for a parameter set:

• left and right arrows move between the parameters

• up and down arrows change the value of a parameter

• Ok Save parameter or Esc Retain previous setting.

The cursor moves back to the identifier T1.

Press Esc to leave the parameter display. The parameter display is opened via the

PARAMETER menu. “{” coil terminals for counters and timers are not displayed

here, even if they have been programmed.

Variable Parameters for Function Relays

You can modify the relay parameters used in the circuit diagram in three different

ways:

• All circuit diagram parameters can be adjusted in Stop mode via the circuit

diagram.

• Setpoints can be modified in Run mode via the circuit diagram.

• Setpoints can be modified via the PARAMETER menu.

The following setpoints can be modified

• the timer setpoints for timing relays

• the counter setpoints of counter relays

• the day and ON/OFF times of time switches

• the comparison setpoint of analog comparators.

In Run mode, Pico operates with a new setpoint as soon has it is modified in the

parameter display and saved.
