■Set value change completed flag (b12)
When adjusting the offset gain setting, use 'Set value change completed flag' (Un\G69, b12) as an interlock condition to turn
on and off 'Value change request Un\G70, b12).
When the external power supply is off, the 'Set value change completed flag' (Un\G69, b12) does not turn on. After turning on
the external power supply, turn on and off again 'Value change request' (Un\G70, b12).

■Disconnection detection signal (b13)
'Disconnection detection signal' (Un\G69, b13) turns on when a disconnection is detected in a channel while the current of 4 to
20 mA, 0 to 20 mA, or user range is in use.
If disconnection detection auto-clear enable/disable setting is disable, 'Disconnection detection signal' (Un\G69, b13) turns off
by turning on and off 'Error clear request' (Un\G70, b15) or 'Operating condition setting request' (Un\G70, b9) after the cause
of the disconnection is eliminated.
When the cause of disconnection is eliminated if disconnection detection auto-clear enable/disable setting is enable, the
disconnection detection signal automatically turns off.

■Alarm output signal (b14)
If the D/A conversion is enabled, this signal turns on when the 'CH1 Digital value' (Un\G460) exceeds 'CH1 Alarm output
upper limit value' (Un\G510) or falls below 'CH1 Alarm output lower limit value' (Un\G512).
By turning on and off 'Alert output clear request' (Un\G70, b14) or turning off and on 'Operating condition setting request'
(Un\G70, b9) after the cause of the warning is eliminated, 'Alert output signal' (Un\G69, b14) turns off and 'Latest alarm code'
(Un\G2) is cleared.
