Operating buttons
Operating buttons Operating buttons
Operating buttons - Pico has eight operating buttons. These are used to select
menu functions and create circuit diagrams. The large round button in the middle
is used to move the cursor. DEL, ALT, ESC and OK all perform additional
functions.
Operating mode
Operating modeOperating mode
Operating mode - Pico has two operating modes: RUN and STOP. RUN mode is
used to process your circuit diagram (with the controller running continuously). In
STOP mode you can create your circuit diagrams.
Output
OutputOutput
Output - You can connect various loads to the four Pico outputs, such as
contactors, lamps or and motors. In the circuit diagram, the outputs are activated
via output relay coils “Q1” to “Q4”.
P buttons
P buttonsP buttons
P buttons - The P buttons can be used to simulate four additional inputs which are
controlled directly by the four cursor buttons, rather than via external contacts.
The relay contacts of P buttons are connected up in the circuit diagram.
Parameters
ParametersParameters
Parameters - Parameters enable the user to set the behavior of a function relay.
Examples include switching times or counter setpoints. They are set in the
parameter display.
Power supply
Power supplyPower supply
Power supply - Pico AC controllers are powered by ac voltage at 120 to 240V ac,
50/60 Hz. The terminals are labeled “L1” and “L2”. Pico DC controllers are
powered by dc voltage at 24V dc. The terminals are labeled “+24V” and “com”.
The terminals for the power feed are the first three terminals on the input side.
Retention

Retention - The retentive data is kept even after the Pico power supply is switched
off. The following data is retentive:
• Pico circuit diagram
• Parameters, setpoint values
• Te xt di sp la ys
• System settings
• Password entry
• Actual values of marker relays, timing relays, counters
