(2) After the input range setting is changed, the temperature measurement value
turns to "0" for about 8 seconds.
(3) When changing the input range, make setting so that the upper and lower setting
limiter values are within the temperature measurement range.
(4) To determine the set value change, you must turn on the setting change
command (YnB).
(1) Sets the mode to be entered at a PID operation stop.
The default value (initial value) is set to "monitor".
(2) Operation varies with the mode setting made as indicated below.

Alert
Operation is governed by the unused channel setting, setting/operation mode
setting, PID continuation flag, forced stop command and CPU error stop-time
control output setting. (Refer to Section 3.2.13.)
(a) Temperature judgment: A temperature is input from the temperature sensor to
check whether it is within the temperature measurement range of the input
range setting.
(b) Alert judgment: Alert checks 1 to 4 in Section 3.5.4 are made.
POINT
The default value (initial value) of the stop mode is set to "monitor".
Hence, the channel without a temperature sensor connected results in a sensor
input disconnection and the "ALM" LED is lit.
For the channel to which a temperature sensor is not connected, set "1 (unused)"
to the unused channel setting buffer memory (3D
