RECALIBRATION
F Option
1. Make all connections according to the wiring diagram, or as
shown on the job diagrams, in compliance with national and
local codes. Make all connections with power removed. Failure
to do so could result in circuit board damage.
2. Connect the highest quality gauge available to the branch line
of the transducer.
3. Move the jumper to the CAL position (see Wiring).
4.
Vary the input signal to the transducer until the gauge indicates
the minimum branch pressure desired to output. If the transducer
is equipped with the manual output adjust option, set the
minimum branch pressure by putting the manual output adjust
jumper in the ENABLE position and turning the manual pot.
5. Adjust ZERO pot for 4 mA output from the transducer feedback
terminals.
6. Repeat step 4 to set the maximum branch pressure. If
maximum pressure cannot be reached, adjust GAIN pot.
7. Adjust the SPAN pot for 20 mA output from the transducer
feedback terminals.
8. Since SPAN and ZERO pots are interactive, repeat steps 4, 5, 6, and 7 until results are accurate.
9. Move CAL jumper back to the normal position and move the manual output adjust jumper back to the disable position.
10. Input the maximum input signal and adjust the GAIN pot until the desired maximum pressure is indicated on the gauge.
V Option
1. Make all connections according to the wiring diagram, or as shown on the job diagram, in compliance with national and local
codes. Make all connections with power removed. Failure to do so could result in circuit board damage.
2. Connect the highest quality gauge available to the branch line of the transducer.
3. Apply the new input voltage desired for maximum pressure (limited to a range of 5-15 VDC).
4. Adjust the GAIN pot until the pressure gauge shows a slight change in pressure.
5. Now, adjust the GAIN pot until maximum pressure shows on the gauge.
6. The transducer is now recalibrated to the new voltage input span (max to min 5:1 ratio).
DESCRIPTION
F Option
The Feedback Loop Control F Option outputs a current
sourcing 4-20 mA signal representative of the branch output
pressure. The standard range is 4-20 mA to 3-15 psig (20.7-
103.4 kPa). F Option also allows for custom ranging the
output (i.e., 4-20 mA to 8-13 psig). Any range from 3-15 psig
(with a minimum 5 psig span) can be field-calibrated. This
option requires 24 VAC/DC power.
V Option
The Voltage Input V Option allows the UCP-422 to be
controlled by any voltage signal with a 5:1 ratio span. For
example, the voltage signal span could be 1-5V, 2-10V, or
3-15V . This option requires 24 VAC/VDC power.
