I.1.10 Scrolling Set-point
The CS access ory (scrolling Set-poi nt, vi a 4÷20 mA external analogue
signal by installer) can assume two func tioni ng logics (factor y set
according to request):
"Shifting Set-point" logic;
"Offset Set-point" logic.
In the Shifting Set-point l ogic, the analogue signal (opportunely
configured) s ets the Set- point at which the machine must operate
directly (the Set-point set on the c ontrol panel is bloc ked).
In the Offset Set-poi nt logic, the analogue signal (opportunel y
