CH2 Addition Input
(Block Function)
Addition value of CH1 and CH2 will be the input value for CH2, and control
for CH2 performs using this value.
PV = (CH1 PV + CH2 PV)
Set values such as input type, scaling and PV filter time constant can be
set to CH1 and CH2 individually.
However, if CH ranges differ from each other, indication and addition will be
based on the Base channel.
Attached Functions
Sensor Correction
When the sensor measured temperature deviates from the temperature in
the controller location, this corrects PV by adjusting the input value of
sensors. However, it’s only effective within the input rating range
regardless of the sensor correction value.
• Correction range: -100.0 to 100.0
( )
DC current, voltage input: -1000 to 1000 (The placement of the decimal
point follows the selection)
Set Value Lock
Locks all set values so as not to be changed
Automatic Cold
Junction Temperature
Compensation (only
thermocouple input)
This detects the temperature at the connecting terminal between the
thermocouple and the instrument, and always maintains it at the same status
as if the reference junction location temperature was at 0
(32
).
Burnout (Overscale)
When the thermocouple or RTD input is burnt out, control output is turned
OFF (for DC current output type, output low limit value), and the PV/SV
display flashes “
”. However, the infrared thermocouple is excluded.

DC input disconnection
:
When DC input is disconnected, the PV display flashes “
” for 4 to 20
mA DC and 1 to 5 V DC inputs, and “
” for 0 to 1 V DC input. For 0 to 20
mA DC, 0 to 5V DC and 0 to 10 V DC inputs, the PV display indicates the
value corresponding with 0 mA or 0 V input.
