(1) Function
Switches the mode of the A/D converter module.
• Normal mode to offset/gain setting mode (the offset/gain setting mode flag (XA)
turns ON)
• Offset/gain setting mode to normal mode (the offset/gain setting mode flag (XA)
turns OFF)
POINT
(1) When the offset/gain setting mode is switched to the normal mode, Module
ready (X0) turns from OFF to ON.
Note that initial setting processing will be executed if there is a sequence
program that makes initial setting when Module ready (X0) turns ON.
(2) When the offset/gain setting mode is switched to the normal mode, the Q64AD-
GH holds the previous operation condition and resumes operation
automatically under the previous operation condition.
(3) When one mode is switched to the other (the normal mode is switched to the
offset/gain setting mode or the offset/gain setting mode is switched to the
normal mode), the Q62AD-DGH suspends A/D conversion and switches OFF
the power supply to the 2-wire transmitter.
To resume A/D conversion and power supply to the 2-wire transmitter, turn ON
the operating condition setting request (Y9) after the mode is switched to the
normal mode.
(2) Operation error
No errors.
