Hysteresis function
8.2.7
The hysteresis keeps the switching status of the
output stable if the flow rate fluctuates around the
nominal value. When the flow rate increases, the
output switches upon reaching the switch point
SPx. If the flow rate decreases again, the output
only switches back when the return switch point
rPx is reached.
The hysteresis is adjustable:
First the switch point is determined, then the
return switch point at the required distance.
Window function
8.2.8
The window function allows a defined OK range
to be monitored. If the flow rate fluctuates
between switch point SPx and return switch point
rPx, the output is switched through (window
function/NO contact) or opened (window
function/NC contact).
The size of the window is adjustable by the
distance between SPx and rPx.
SPx = upper value; rPx = lower value.
Press and hold Set.
