(1) This signal (XE) turns on when the measured temperature values of all conversion-enabled
channels are stored into buffer memory after power-on or hardware reset.
(2) When averaging processing is performed, this signal also turns on when the measured
temperature values are stored into buffer memory after completion of averaging processing.
(3) This signal (XE) varies as described below depending on whether the Operating Condition
Setting Completion Signal (X9) has turned on or off.
• When the Operating Condition Setting Completion Signal (X9) has turned on
(stop conversion)
1) Temperature measurement of the enabled channel is started.
2) After the measured temperature values are stored into buffer memory, the conversion
completion flags (buffer memory address 10: Un\G10) are turned on.
3) This signal (XE) is turned on after the measured temperature values of all conversion-
enabled channels are stored into buffer memory.
• When the Operating Condition Setting Completion Signal (X9) has turned off
(conversion stop)
1) The conversion completion flags (buffer memory address 10: Un\G10) of all channels are
turned off.
2) This signal (XE) is turned off.
Note that if conversion is stopped, the measured temperature values stored in buffer
memory are held at the data immediately before the stop.
(4) Read a measured temperature value using this signal or the Conversion completion flag (buffer
memory address 10: Un\G10) as an interlock.
(5) This signal (XE) does not turn on when all channels are disabled for conversion.
(1) This signal (XF) turns on when an error occurs.
(2) To clear the error code, turn on the Error Clear Request (YF).
