Re-transmission Output Function
The re-transmission output function delivers an analog output signal from the controller.
The following values can be output:
PV, SV, MV, DV (PV-SV), PFB
Depending on the type of output, you can choose the voltage type or current type.
The re-transmission output also contains a scaling function.
The following example shows a re-transmission output of 100% when PV=960°C (80% FS)
and a re-transmission output of 0% when PV=240°C (0% FS) for a PV range of 0 to 1200°C.

1. Soft start function
When turning on the equipment (including the temperature controller), the soft start function
suppresses the MV to become maximum output. It places an upper limit on MV output for a
specified amount of time after power is turned on.
This function is useful for effects such as suppressing the heater output during equipment star-
tup, and makes load lightened.
After the specified time has passed after switching on the equipment (or if SFTM = 0), the soft
start function ends and normal controls begin.
