3.13 Setting and Monitoring DIDO/AI/PI Controllers
The “Setting and Monitoring DIDO/AI/PI Controllers" has been located starting from Ver4.20.
* Items Performed Here
- Settings and monitoring DIDO Controller (PAC-YG66DCA), AI Controller (PAC-YG63MCA), and PI
Controller (PAC-YG60MCA) can be made. (PI Controllers can be used only for monitoring.)
- DIDO Controllers and AI Controllers have an interlock control function.
DIDO Controllers can also change the operation status of M-NET devices (such as indoor units, DIDO
Controllers) by sending operation commands. DIDO Controllers can output contacts on DIDO Controllers
themselves depending on the change in input contact status.
AI Controllers can change the operation status of M-NET devices (such as indoor units, DIDO
Controllers) by sending operation commands depending on the change in measurement values.
“Interlock operation conditions” for the “interlock control function” can be set on Maintenance
Tools.
3.13.1 Setting and Monitoring DIDO Controllers (66DC)
DIDO Controller(PAC-YG66DCA) can be used in combination with a system controller (G(B)-50A or
TG-2000A) to operate/stop general-purpose equipment, as well as to monitor the operating status and error
status.
Furthermore, DIDO Controller is equipped with two sets (channels 1 and 2) of standard terminals and four
sets of expansion connectors as the input/output terminals.
NOTE:
Before using the interlock control function, plan carefully how the air-conditioners will be used. If
the interlock control function is used without thorough consideration, unexpected operation may
result.
