25.3.1.3. M.TUNE.PWM – Optimization of the PWM signals
In this menu the PWM signals for control of the aeration valves and bleed valves are manually optimized.
For optimization the actuator is aerated and bled. A progress bar on the display indicates the position of the
actuator and the speed of aeration and deaeration.
The setting is optimum when the progress bar moves as slowly as possible.
WARNING!
Danger.due.to.uncontrolled.valve.movement.when.the.M.TUNE.PWM.function.is.running!
When the M.TUNE.PWM function is running under operating pressure, there is an acute risk of injury.
▶ Never run M.TUNE.PWM while a process is running!
▶ Secure system against unintentional activation!
