mA INPUT PARAMETERS (P250,P251,P252)
If HYDRO+ features are required based upon measurements obtained from another
level monitor, alter the following parameters as required.
This feature enables virtually all HYDRO+ (excluding Transducer specific) features to
be used, based upon the measurements of another level monitor (or any device
providing a 0 to 20 mA or 4 to 20 mA output proportional to level).
To use this feature, do not connect an ultrasonic transducer to the HYDRO+
transducer terminals). Connect the mA output of the device to the HYDRO+ mA input
terminals, and set TRANSDUCER to "Auxiliary" (P004 = 250).
Do not connect the auxiliary device to the HYDRO+ transducer terminals.
P250 (G) mA INPUT RANGE
Enter the mA output range of the auxiliary level monitor connected.
value: 1 = 0 to 20 mA
2 = 4 to 20 mA (preset)
INDEPENDENT mA INPUT SETPOINTS (P251 and P252)
Use these features to define the levels associated with the mA Input
Range. Enter the levels in Units (P004) or % of Span (P007), as
referenced to Empty (P006).
Ensure the % symbol is displayed before attempting to enter a % value,
(see PROGRAMMING Keypad).
P251 (G) 0/4 mA INPUT SETPOINT
Enter the level (in Units or %) to correspond to 0 or 4 mA.
As preset, 0 or 4 mA (dependent upon mA Input Range, P250) "IN"
represents a level at 0 % of Span (or equivalent units).
values: -999 to 9999
P252 (G) 20 mA INPUT SETPOINT
Enter the level (in Units or %) to correspond to 20 mA.
As preset, 20 mA "IN" represents a level at 100% of Span (or equivalent units).
values: -999 to 9999
