8.7.3 External preselection (IN X)
You can configure an analog input as a preselection for the 3-position output. The
controller performs a maximum selection together with the internal signals.
Maximum selection in
case of several
preselections
For example, you can use this feature to implement the following function: Use of
the RLU202 / RLU222 universal controller as DC 0…10 V signal converters => 3-
position.
The external signal is considered only if the controller operates in Comfort or
Economy mode.
Note
8.7.4 Function check / wiring test (TEST)
During the wiring test, the 3-position output can be directly commanded via the
control switch.
Switching on / off
The switch has the following positions:
Switch positions
• Standstill (----)
• Open (OPEN)
• Close (CLOS)
When you enter the commissioning menu (COMMIS) the 3-position actuator travels
to the 0% position (CLOS).
Notes
When you leave the COMMIS menu, the controller does not compensate for any
changes made to the 3-position output during the wiring test. This does not take
place until after the first synchronization.
8.7.5 Priorities
The following 2 priorities apply to the 3-position output:
2 priorities
1 On / Off during the wiring test
2 According to the positioning signal from the sequence controller (preselection in
normal operation) and external preselection (maximum selection)
