Set values for "Rate alarm upper limit value" and "Rate alarm lower limit value".
The rate input and the digital output value input vary depending on the rate alarm change rate selection.
• When the rate alarm change rate selection is "Rate specification"
Set it in increments of 0.1% for the width of the analog input range (gain value - offset value).
Item
Rate alarm upper limit value
Rate alarm lower limit value
• When 'Rate alarm change rate' is "Digital output value specification"
Set a value for the range of the digital output value in increments of 1 digits.
Item
Rate alarm upper limit value
Rate alarm lower limit value
Set values within the range satisfying the condition "Rate alarm upper limit value > Rate alarm lower limit
value".
If a value out of the range is set, a rate alarm upper/lower limit setting value inversion error (error code:
1BAH) occurs.
4.
Set an alarm detection cycle of rate alarms.
Set the cycle in "Rate alarm detection cycle setting".
Item

A channel where the set value is out of the above range causes a rate alarm detection cycle setting range
error (error code: 1B9H).
