Appendix 611
Input for Monitoring
Wire according to the following procedure depending on whether input is “voltage” or “no voltage.”
„
For voltage input:
Set the voltage / no voltage changeover switch (SS1) to “voltage.” (Factory set setting complete)
„
For no voltage input:
Set the voltage / no voltage changeover switch (SS1) to “no voltage.”
„
If you want to connect output which is to be ON when apparatus is operating normally, disconnect the
short circuit wire between B1 and BC and connect output of the apparatus here.
„
Connect output which is to be ON when apparatus is malfunctioning between B2 and BC. (You can
fetch stop malfunction in the case of stop malfunction.)
„
When operating from optional controllers for centralised control, if between B2 and BC is ON or stop
malfunction with / without switch (SS3) is set to “with,” in the case of between B1 - BC being ON,
optional controllers for centralised control display a malfunction (malfunction code A1).
„
After switching from OFF to ON with an optional controller for centralised control, it takes 10 - 30 for the
monitor to display a malfunction.
Individual
Changeover Switch
(SS2)
Switch for toggling between individual mode and dedicated central mode (stop cannot be effected from
other air conditioner).
For “without individual,” stop can be effected from optional central controller only.
For “with individual,” stop can be effected from other air conditioner as well.
(Factory set is “without individual.”)
Malfunction Signal
Switch (SS3)
Switch for carrying out malfunction detection for stop operation from optional central controller.
In the case of “with stop malfunction,” if operation concerning stop does not follow, the optional central
controller carries out display of malfunction.
In the case of “without stop malfunction,” even if operation concerning stop does not follow, the optional
central controller does not carry out display of malfunction.
(If SS2 is set to “with last command priority,” this switch becomes inoperable.)
(Factory set is “without stop malfunction.”)
Output Changeover
Switch (SS4)
Switch for toggling relay output between constant and instantaneous.
(Factory set is “instantaneous.”)
