■
Any value
At the time of the disconnection detection, a value set in 'CH1 Conversion setting value at disconnection detection' (Un\G532)
is stored in 'CH1 Digital output value' (Un\G400).
The default value of 'CH1 Conversion setting value at disconnection detection' (Un\G532) is 0. The value can be changed to
any value although using 0 is no problem.
• When the scaling function is used, a value according to the setting of 'CH1 Conversion setting at
disconnection detection' (Un\G534) is scale converted and then stored as a scaling value.
• When using the shift function, the value obtained by the conversion value shift rate to the scale converted
value is stored.

2.
Set "Input signal error detection/disconnection detection auto-clear enable/disable setting" to "Enable" or "Disable".
3.
Using "Conversion setting for disconnection detection", set what value is to be stored in 'CH1 Digital output value'
(Un\G400) at the time of the disconnection detection.
4.
When "Given Value" is set, set "Conversion setting value for disconnection detection".
It takes up to 355 ms to detect a broken wire.
