Functional principle of the joker² light barrier system

Figure 21 shows a principle wiring diagram for the connection of two induc-
tive loads (solenoid valves, solenoids, relays, etc.) to an output.
If inductive loads are connected, it is mandatory to connect a recov-
ery diode in parallel to each inductor (coil), as shown in the wiring
diagram. The correct polarity of the diode must be observed.

Default setting:
end
This parameter determines what shall happen after the end of the current
step duration.
With the setting
end
the step chain is terminated.
If the step chain is to be continued, the next step is specified here. Steps can
be concatenated in any order.
If a certain step was already used as a following step, it cannot be
specified once more as next step. This will prevent cross-connections
between step chains which can lead to unexpected behaviours.
If the first step of a chain is specified as the
next step
in the last step of a
chain, an endless loop is created. This is started with the trigger condition
specified in the first step and can only be interrupted in the working level by
pressing the
or
key (change to the Alignment level)!
