■Offset/gain initialization completed flag (b5)
• Use as an interlock condition to turn offonoff 'Offset/gain initialization request' (Un\G70, b5).
• Offset/gain initialization is not be performed unless 'Offset/gain initialization enabled code '(Un\G305) is set to E20FH.
• It is possible to perform offset/gain initialization in normal mode only.
• When 'Offset/gain initialization request' (Un\G70, b5) is off, 'Offset/gain initialization complete flag' (Un\G69, b5) turns off.

■Disconnection detection signal (b6)
Turns on when disconnection is detected for the channel where Enable (0) is set in 'CH1 Disconnection detection enable/
disable setting' (Un\G531) and the conversion is enabled.
When 'Disconnection detection signal' (Un\G69, b6) turns on, the following operations are performed.
• A value corresponding to 'CH1 Conversion setting at disconnection detection' (Un\G534) is stored in the temperature
measurement value of the relevant channel.
• The ALM LED flashes.
Turning off 'Disconnection detection signal' (Un\G69, b6) differs depending on Input signal error/disconnection detection auto-
clear enable/disable setting.

Operations related to the turning off of Disconnection detection signal (Un\G69, b6)
When the temperature input value is within the setting range and the disconnection is restored, the 'Disconnection detection
signal' (Un\G69, b6) automatically turns off, and ALM LED turns off.
Eliminate the disconnection cause, and turn 'Error clear request' (Un\G70, b15) offonoff. 'Disconnection detection signal'
(Un\G69, b6) turns off, ALM LED turns off, and the latest alarm code is cleared.
