Commissioning
The RXC39.5 controller is commissioned with the RXT10 commissioning and service
tool. This is connected to the L
ON
W
ORKS
bus via a tool socket (on the controller or room
unit).
The commissioning procedure for the entire Desigo RXC range is described in
detail in the RXT10 user manual, document CM110669.
The labeling fields “Appl.” and “Loc.” on the controller are used to indicate the
application actually loaded and the location of the controller, either in writing or by
use of printed adhesive labels (see “Label” under “Mechanical design”).
All applications (including basic application 00039) allow direct interrogation of the
inputs and control of the outputs using the RXT10 commissioning and service tool.
This makes it possible to test the installation and to operate connected plant
provisionally before the complete Desigo RXC system is commissioned.
·
The L
ON
W
ORKS
bus plug (terminals 23 and 24) can be removed and
reconnected at any time, even while the controller is in operation. Only the
original bus plug may be used.
·
Overloading the triac outputs Y1, Y2 may cause the thermal fuse to trip and
disable the controller. When the problem has been solved briefly disconnect and
reconnect the power supply. The controller will resume normal operation after a
delay of approximately 10 minutes.
Outputs Y1, Y2 are not protected against accidental connection to AC 24 V.
This can damage the triacs.
