From the First Contact to the Output Coil
With Pico, you work from the input to the output.
1. The first input contact is I1. Press Ok. Pico inserts the first
contact I1 at the cursor position.
The ’I’ flashes and can be changed, for example, to a ’P’ for a
button input using the up or down cursor buttons. However,
nothing needs to be changed at this point.
2. Press Ok twice to move the cursor across the 1 to the next
contact field.
You could also move the cursor to the next contact field using
the right cursor button.
3. Press Ok.
Again, Pico creates a contact I1 at the cursor. Change the contact
number to I2 since break contact (normally closed) S2 is
connected to input terminal I2.
4. Press Ok. Then, press the up or down cursor button to change
the number to 2. Press DEL to delete a contact at the cursor
position.
5. Press Ok to move the cursor to the third contact field. You do
not need a third relay contact, so you can now wire the contacts
directly to the coil field.
