Switching Function
Hysteresis-Mode Window-Mode
In Hysteresis-Mode both switching point SP and
reset point RP can be adjusted freely. The switch
switches back when the RP is reached.
This allows, for example, a simple 2-point control.
With the Window-Mode dened areas can be
monitored. If the process pressure is within the
dened range the output is either closed or open.
Setpoint
It is not possible to adjust RPx > SPx or FLx > FHx.
In general SPx or FHx is leading:
if SPx/FHx > 0 bar, RPx/FLx = 0% FS up to SP -0,5% FS
if SPx/FHx < 0 bar, RPx/FLx = SP +0,5% FS up to 100% FS
Switch Delay
By adjusting switch delay and re-set
switch delay you can change the time
between the detection of a pressure
signal and the switch-over of the digital
output(s).
Note that a delayed signal transmissi-
on might possibly have an impact on
plant safety.
