4-24 Draw a Circuit Diagram with Pico
1. Enter the circuit diagram up to CC1.
CC1 is the contact of counter relay 1. If the cursor is on the
contact number, Pico will call up the parameter display when
you press Ok.
2. Move the cursor onto the 1 in CC1 and press Ok.
The parameter set for the counter is displayed.
3. Move the cursor onto the plus sign to the right of the S
(setpoint) and press Ok.
4. Change the counter setpoint to 10:
Use the left and right buttons to move the cursor onto the tens
digit.
Use the up and down buttons to modify the value of the digit.
5. Press Ok to save the value and Esc to return to the circuit
diagram. Pico has specific parameter displays for function relays.
The meaning of these parameters is explained under each relay
type.
6. Enter the circuit diagram up to contact ’TT1’ of the timing relay.
Set the parameters for T1.
The timing relay works like a flasher/blink relay. The Pico
symbol for the flasher/blink relay is shown in the screen to the
left. It is set at the top left of the parameter display.
7. Press the down arrow and select the flasher/blink relay symbol.
8. Use the right arrow to move to the first time setpoint I1.
9. Press Ok, then press the right arrow.
10. Use the arrows to enter the value 01.000 and press Ok.
The time setpoint I1 for the pause time is 1 second.
11. Use the down arrow to enter the value of the second setpoint I2.
Set this value to 0.5 seconds. This is the time value for the pulse
time.
12. Press Esc to leave the parameter entry.
The values are now stored.
