Frequently Asked Questions
How do I set the control signal to voltage or current?
Control signal type is set by S2-3. 'UI' configures it as voltage, while 'IO' configures it for current signals.
What does the self-adaptation process involve upon startup?
The actuator enters self-adaptation mode, automatically cycles from full off to full on; completion is signaled when the yellow indicator stops blinking.
What happens if the control signal line is interrupted (cut)?
If S2-6 is ON, dedicated fail-safe limits are maintained: max signal for voltage loss or min signal for current loss.
Which dip switch combination activates floating control?
Set S2-7 to ON (for general adaptation mode) and S2-8 to ON (for float control).
