Softstart For Preheating; Heating Output (Fast Cycle) - gefran GFW ADV Configuration Manual

SOFTSTART FOR PREHEATING

This function lets you deliver a settable power (So.P) for time (SoF), after which normal control is resumed by means
of PID control.
Activation is only at switch-on, with manual-automatic switching during Softstart (the time restarts from 0), and if the
process variable is below setpoint SP.S.
From SW version 2.02:
With softstart time SoF = 0, preheat condition PV <SP.S with settable power SO.P is continuously checked.

HEATING OUTPUT (Fast cycle)

For outputs rL.1 (Out 1) and rL.2 (Out 2) you can set a fast cycle time (0.1 ... 20,0 sec) by setting the parameter to
64 (Heat) or 65 (Cool).
