Factory setting: All DIL switches set to OFF
Factory setting SAS..:
· Characteristic curve : log = Equal percentage (switch at "OFF")
· Positioning signal: DC 0...10 V (switch at "OFF")
Factory setting SAT..:
· Characteristic curve: lin = linear (switch at "ON")
· Positioning signal: DC 0...10 V (switch at "OFF")
