Operation performed when disconnection is detected
• At disconnection detection, a rate alarm may occurs as well because 'CH1 Measured temperature value' (Un\G400)
changes according to 'CH1 Conversion setting at disconnection detection' (Un\G531).
• At recovery time from disconnection, previous information (value) of rate alarm is cleared. Therefore, at the restart of
temperature conversion, even if the change rate of the measured temperature value (from before restart to after restart) is
out of the limit range, an alert is not output.
Setting procedure
1.
Set "Warning output setting (Rate alarm)" to "Enable".

Rate alarm detection cycle setting
3.
Set values for "Rate alarm upper limit value" and "Rate alarm lower limit value".
Item
Rate alarm upper limit value
Rate alarm lower limit value
Set the alert output function (rate alarm) to satisfy the following condition. If a value out of the range is set, a
rate alarm upper/lower limit setting value inversion error (error code: 1BAH) occurs.
Rate alarm upper limit value > Rate alarm lower limit value
