The DCR-WEB has an Isolated 0-10 V output. To set up this feature, enter the
two end points. If the level is beyond the bounds of the window created by the
two end points the voltage level will stay at the voltage level of the point it is
nearest to. Refer to the diagram below.
MODE DESCRIPTION PARAMETERS EXPLANATION
0V DIST 0 V Distance Units = inches
Default = 24.0
10V DIST 10 V Distance Units = inches
Default = 48.0
The sensor can be programmed to any maximum voltage desired from 1 to 10.45
VDC. The calibration numbers are used to set the maximum and minimum voltage levels
of the analog slope. In most cases the minimum voltage is desired to be 0 so the value
for 0 V CAL mode is set to 0. However, if it was desired to have the minimum voltage
be 1.0 volts the value of this mode would be set to 4095(1)/10.45=391. The same is true
for the maximum voltage levels. If the maximum voltage is to be 6 VDC then 4095(6.0)/
10.45=2351 would be entered into the 10 V CAL mode.
