CH
Process alarm upper lower limit value (Un\G88, Un\G92, Un\G96, Un\G100),
CH
Process alarm upper upper limit value (Un\G89, Un\G93, Un\G97, Un\G101)
Set the digital output value range for each channel.
For details on warning output function (process alarm), refer to the following.
• Warning Output Function (Process Alarm) ( Page 77, Section 8.9)
(a) Setting range
• Setting range is -32768 to 32767.
• Configure the 4-step setting of process alarm upper upper limit value, process alarm upper lower limit
value, process alarm lower upper limit value and process alarm lower lower limit value.
(b) Enabling the setting
Turn OFF → ON → OFF Operating condition setting request (Y9) to enable the setting.
(c) Default value
0 is set as the default value.
● When a value out of the setting range above or a value which does not satisfy the formula of process alarm upper upper
limit value ≥ process alarm upper lower limit value ≥ process alarm lower upper limit value ≥ process alarm lower lower
limit value is set to a channel, an error occurs in the channel. The error code is stored in Latest error code (Un\G19), and
Error flag (XF) is turned to ON. The operation is performed in the setting configured before the error occurrence.
● Change the setting value, since 0 is set as the default value.
● When the following functions are used, warning targets are scaling values that reflect the operations of each function.
Set values considering operation results of each function.
• Digital clipping function
• Scaling function
• Shift function
• Difference conversion function
