Drawing a Circuit Diagram with Pico 4-31
Parameters for Time Switch
A time switch has four sets of parameters, one for each channel (A, B, C and D).
These are used to set the day of the week and the turn-on and turn-off times for the
desired channels and to enable or disable parameter access. Changing the switching
times is described under Chapter 7.
You can only change the “+”/“–” setting for displaying the parameters via the
PARAMETER menu option when you are editing the circuit diagram.
The current time only appears in the parameter display in Run mode. Call up the
parameter display in Run mode via the power flow display or via PARAMETER in
the main menu.
Switch-On and Switch-Off Times
Analog Comparators
Analog comparators are only available with 24V dc models. They monitor the
voltages of sensors that are connected to terminals I7 and I8.
Pico provides eight analog comparators “A1” to “A8”.
A comparator can perform six different comparisons. The relay
contact switches if the comparison conditions are true.
• I7 greater than or equal to I8, I7 less than or equal to I8
• I7 greater than or equal to setpoint, I7 less than or equal to setpoint
• I8 greater than or equal to setpoint, I8 less than or equal to setpoint
