C3.12 External Input
The input value used for monitoring and controlling may be switched to an external input,
which may be, say, processed data from a CPU module.
An external input must fall within the range of -5.0% to 105.0% of (SL to SH).
Use the EXPV/PV parameter to switch between external input and normal input.
An external input may also be used for testing without a thermocouple or sensor
connected.
