Step 8: General Purpose Equipment Control - Mitsubishi Electric G-50A Technical Manual

11. Step 8: General Purpose Equipment Control

TG-2000A can control and monitor system equipment.
By using general-purpose control functions, you can control and monitor other manufacturer's air
conditioning units, lighting fixtures and other system equipment as well as water level of a water or fire tank
with a flooding/low level alarm on the TG-2000A monitor screen.
System equipment is controlled by PLC. "General-purpose control software: PAC-YG21CDA" needs to be
installed in PLC. (For PAC-YG21CDA Ver.1 series, no licensing registration needed for G-50A.)

Operation and monitoring of general purpose system equipment cannot be
controlled if the PLC or other equipment fails. Take this into consideration, and
make sure you provide a circuit for a switch for an emergency stop/start. Do not
use it for monitoring the system affecting human life. In case you do, incorporate
an alternative safety mechanism.
