7 Settings
By using the programming unit HPG 3000, it is possible to make the following settings in the
EDS 4000:
7.1 Switch point settings
This sets the switch value at which the switching output will switch when the
value is exceeded (above or below) according to its pre-set switching
direction (see 7.3).
Abbreviations: “
SP.1
“ = Switching point 1
“
SP.2
“ = Switching point 2
(only on units with two switching points)
7.2 Hysteresis settings (Switch-back point)
This sets a hysteresis to the switching point. The switching output switches
back if the value falls below the switch-back point. The switch-back point is
determined by the pre-set hysteresis (switch-back point = switching point
minus hysteresis).
Abbreviations: "
HYS.1
“ = Hysteresis SP1
"
HYS.2
” = Hysteresis SP2
(only on units with two switching points))
7.3 Switching direction (N/O or N/C-function)
The switching direction determines if the switching function is to be normally
open or normally closed. (on = N/O-function / oFF = N/C-function)
Abbreviations: "
S.d.1
" = Switching direction SP1
"
S.d.2
“ = Switching direction SP2
(only on units with two switching points)
7.4 Switch on delay
Time in milliseconds [ms] which must elapse, once the switching point has
been reached or exceeded, before switching will occur.
Abbreviations: "
T.on1
" = Switch on delay [ms] SP1
"
T.on2
" = Switch on delay [ms] SP2
(only on units with two switching points))
7.5 Switch off delay
Time in milliseconds [ms] which must elapse, once the pressure has fallen
below the particular switch-back point, before switching will occur.
Abbreviations: "
T.oF1
" = Switch off delay [ms] SP1
"
T.oF2
" = Switch off delay [ms] SP2
(only on units with two switching points)
