Softstart For Preheating - gefran GFX4 Configuration And Programming 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.
