Channels 1 and 2 are warning output enabled.
(3) The Operating Condition Setting Request (Y9) must be turned on/off to make the
warning output enable/disable setting valid.
(1) When CH measured temperature value (buffer memory addresses 11 to 14, 54

output upper/lower limit value (buffer memory addresses 86 to 117: Un\G86 to
117), the warning output flag of the corresponding channel turns to 1.
(2) You can check whether the warning given is the upper or lower limit value warning
on each channel.
(3) When the measured temperature value returned to a value within the
measurement range, the flag is automatically reset.
(4) If a warning is detected on any of the channels enabled for conversion, the
Warning Output Signal (XD) turns on.
(5) The warning output flag is cleared when the Operating Condition Setting Request
(Y9) is turned on.
Also, only for the Q64RD-G, "ALM LED" turns OFF from ON.
