Example
In a heating control system, the supply T
temperatures T
sensor at AI2.
A control signal is to be triggered (for example "heater On")
when the difference between the supply and return line
temperatures is greater than 15. The control signal is reset
when the difference is less than 5C.
The process variable of the temperature is to be shown in
parameter assignment mode.
The thermocouples available have the the following
technical data: -30 to +70C, 0 to 10 VDC.
