The control unit AU S3 is equipped with two output relays A and B (with
guided contacts). Even if these relays are specified for higher coil voltages
and load currents, make sure that the load features comply with the
indications of the following table to guarantee a correct operation and
avoid damage or quick ageing of A and B internal relays.
For loads with higher switching characteristics use K1 and K2 additional
relays.
Use of additional relays K1 and K2.
Use of additional relays K1 and K2.
Use of additional relays K1 and K2.
Use of additional relays K1 and K2.
If additional relays K1 and K2 are used to increase the number of contacts
available on the AU S3 control unit or to increase the switching capacity of
its inner relays A and B, connection diagram B (page 27) must be used.
•
K1 and K2 must be safety relays with guided contacts.
•
Used K1 and K2 contacts as indicated in the following table.
