Condition: The Alarm 1 must be allocated for control output or auxiliary
output. Analog output models only.
• This parameter sets whether to output only the alarm 1 output or whether
to output an OR of the alarm 1 output and sensor error alarm output when
an alarm 1 output is allocated in control or auxiliary output.
• When the sensor error alarm output is enabled (on), alarm 1 for ch1 will
turn ON when a sensor error occurs in a ch1 input, and alarm 1 for ch2
will turn ON when a sensor error occurs in a ch2 input.
• Set the input alarm output to OFF when moving to the initial setting level,
advanced function setting level, or communications setting level.
• This parameter is supported by analog output models only.

Condition: Input type must be thermocouple or infrared temperature
sensor.
• Specifies whether cold junction compensation is to be performed inter-
nally by the Controller or to be performed externally when the input type
set value is No. 0 to 15, 17 or 18.
• The cold junction compensation external setting is valid when the temper-
ature difference is measured using two thermocouples or two ES1As.
• Setting changes to "cold junction compensation method" must be enabled
by executing a software reset or by turning ON the power again.
