Note With a TC2, the Channel 3 and 4 MVs will be set to 0.0%.
G3ZA Models with 8
Channels The following outputs will be sent whether the control method is set to stan-
dard or heating/cooling control.
Note With a TC2, the Channel 3 to 8 MVs will be set to 0.0%.
MVs Output from the
G3ZA
The outputs of predetermined channels are set in the G3ZA's MV, but any MV
can be output to multiple channels by setting the G3ZA's “Source Channel.”
Arithmetic operations can also be executed on each MV.
!Caution If the MV is stored or calculated at the G3ZA and the G3ZA is turned ON
before the EJ1G, the controlled variable produced at the G3ZA will be output
(the output may not be 0.0%) until the EJ1G starts operating. When using MV
storage or MV calculation, verify that the controlled variable produced by the
G3ZA is appropriate.
