Max. slide
When selecting this function, the output will be activated when the relative travel of the capacity
slide position, Capacity slide position [%] > Signal high [%].
When calculating the relative position of the capacity slide, the absolute travel of the capacity
slide position and the Vi slide position is included. The hysteresis between active and inactive
signal is 1%.
Please note that the line
Signal high
is not included in the menu until the auxiliary output has
been selected as

Select this function for SAB 193 H - 355 H to control the balance piston. Set the
Signal high
limit
and the
Signal low
limit to appropriate values, both referring to relative slide capacity.
If selecting this function, the output will be activated when the relative travel of the capacity slide
position, Capacity
relative
[%] < Signal low [%] OR Capacity
relative
[%] > Signal High [%] = AUX Out-
put active.
When calculating the relative position of the capacity slide, the absolute travel of the capacity
slide position and the Vi slide position is included. The hysteresis between active and inactive
signal is 1%.
Please note that the line
Signal low
and
Signal high
is not included in the menu until the auxiliary
