Modules
The relay contact L can be supplied with 230 VAC external voltage.
By closing the relay, the voltage applied to L will be switched to the second
relay contact DO.
The relay contact L is also equipped with two parallel connections.
Therefore, the voltage can be applied via one or two conductors of cross sec-
tion > 2.5 mm². The voltage can also be supplied to the following modules via
the second connection.
The automatic or manual operating mode can be selected using the "man-
ual/automatic" switch.
In the "automatic" operating mode, the relay is operated via the control system
requiring a 24 V power supply fed in via the internal power jumper contacts of
an adjacent supply module.
In this operating mode, manual status transitions which may occur via the red
"manual operation" switch (1/0) will be reset by the control system after less
than 500 ms.
In the "manual" operating mode, the relay cannot be switched via the control
system. Operation can only be performed manually via the red "manual opera-
tion" switch (1/0). Moreover, the actuator can be switched without 24 V
power supply.
