Series Connection
Q1 is controlled by a series circuit consisting of three make contacts
(AND circuit).
Q2 is controlled by a series circuit consisting of three break contacts.
In the Pico circuit diagram, you can connect up to three make or
break contacts in series within a circuit connection. Use ‘M’ marker
relays if you need to connect more than three make contacts in series.
(see page 4-10)
Parallel Connection
Q1 is controlled by a parallel circuit consisting of three make contacts
(OR circuit).
A parallel circuit of break contacts controls Q2.
