SPECIFICATIONS
3.4.21 CH[ ] Process alarm upper/lower limit values (Un\G94 to Un\G125)
Process alarm upper upper limit value, upper lower limit value, lower upper limit value, and
lower lower limit value can be set. (Refer to Section 3.2.4)
(1) Setting methods
(a) A scaling range of measured temperature values is set for each channel in units of
0.1 .
Settable range and default value differ according to the thermocouple type.
The following table shows settable range and default value for each thermocouple
type.
(b) Turn on Operating condition setting request (Y9) to activate the setting.
POINT
(1) If any of the following values are set, an error (error code: 6 ) occurs.
Then, Error flag (XF) turns on.
• A value out of the above settable range:
• A value that does not satisfy the following condition:
Process alarm lower lower limit value lower upper limit value upper lower limit value
upper upper limit value
(2) When “Disable” (“0”) is set in the Warning output enable/disable setting
(Un\G46), the setting of CH Process alarm upper/lower limit values
(Un\G94 to Un\G125) is ignored.
