8.1 SWITCHING OUTPUTS
The EDS 3000 has either 1, 2 or 4 switching outputs.
The following output signals can be set in the basic settings:
8.1.1 Switch point setting (SP)
One switchpoint and one hysteresis can be set for every switching output. The particular
output will switch when the set switch point is reached and switch back when the
measurements drop below the switch-back point. The switch-back point is always
determined by the set hysteresis.
(switching point minus switching hysteresis = switch-back point)
Abbreviations: "S.P.1", "S.P.2", "S.P.3" , "S.P.4" = switching point 1 to 4
"HyS.1", "HyS.2", "HyS.3" , "HyS.4" = hysteresis 1 to 4
8.1.2 Window mode (WIN)
Operating in window mode allows the unit to monitor a range. An upper and a lower
switching point which defines the range can be assigned to each switching output.
The particular output is switched when the level or temperature enters this range.
The output switches back when leaving the range. The lower switch-back value is
just below the lower switching value (lower switching value minus 1% FS, see section
8.4). The upper switch-back value is just above the upper switching value (upper
switching value plus 1% FS, see section 8.4). The range between the switch value
and the switch-back value forms a safety margin which prevents unwanted switching
operations from being triggered.
Example for switching output 1 (normally open):
Abbreviations: "HI 1" to "HI 4" = High level 1 to 4 = upper switching point 1 to 4
"Lo 1" to "Lo 4" = Low level 1 to 4 = lower switching point 1 to 4
FS (full scale) = relative to the complete measuring range
NOTE:
The window function will only operate properly (switch on and off), if all switching
values (including the safety zone) are greater than 0 inch or –9.4 °F (model with
temperature sensor), and are within the unit's nominal measuring range.
