Softstart (general function):

During the softstart the controllers’ output response is limited to a pre-selected ratio, in order
to achieve a slow baking out of high performance heat cartridges.
Simultaneously the output clock frequency is quadrupled. Once the process value reaches
the softstart setpoint, it remains stable at this value for a pre-selcted hold-duration time.
At the end of this period the process value rises to the valid setpoint.
This results in a slower, more regular heating period.
For this purpose the bistable voltage output must be chosen, that actuates SSR relays.
If the softstart is active, the controllers’ autotune function can’t operated (Er.OP).
If a setpoint-ramp has been programmed, the softstart has priority, and the ramp will only
become active after the softstart has been completed.
The softs
tart only works, if the parameter „1 P“ (prop. band, xp) is programmed > 0,1%.
