Analog Output
The HydroRanger I can be programmed to provide an analog output (P-6) of 0 or 4 - 20
mA, proportional or inverse span.
The 4 and 20 mA levels can be trimmed slightly via P-97 and P-98 respectively to
compensate for any offset between the HydroRanger I and the customer’s equipment.
The analog output feature may be turned OFF by setting P-6 = 0. The output and
alternate displays ( & P-92) will immediately drop to 0 mA after a new
measurement is processed. The output will remain disabled during simulation (P-76, 77
& 78). However, the test routine of P-92 and the trim parameters will remain active. If
P-60
≠
0, then the analog output will return to its programmed output after a new
measurement is processed.
If the analog output must be isolated, the optional mA isolator Model LIs-1 must be
mounted on the motherboard and wired per Figures 2 and 3. When using the isolator
the load adjust can be done via P-97 and 98 rather than via the load adjust
potentiometer as mentioned on the isolator instruction sheet, PL-293.
The current output responds in the following manner:
