CONNECTIONS

POWER INPUT: 100 to 240 VAC 50/60Hz. No adjustments are necessary for voltages within this

range. Connect L (Live) N (Neutral) and AC Ground.

Optional DC: 9-32 VDC. Connect to + and - terminals.

Optional Thermostat and Heater modules are available rated for 115 VAC or 230 VAC.

IMPORTANT NOTE: AC power input and relay connection wires must have conduit entry to the

instrument enclosure. Installation requires a switch, overcurrent fuse or circuit breaker in the building (in

close proximity to the equipment) that is marked as the disconnect switch.

Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel

should access connections.

Note: Use of instrumentation over 40°C ambient requires special field wiring.

Note: User replaceable fuse is 2 Amp 250V (T2AL250V).

FUNCTION TEST:

Connect the sensor to the sensor terminals as shown on next page, then

apply power. Allow 30 seconds for the UF AV5500 to initialize.

A. Place QZ02L sensor (flat to the bottom) in a bucket of water

about 6” deep and press the programing button to view

the status page which shows level and velocity. Stir the

water to see a velocity reading.

KEYPAD SYSTEM

The UF AV5500 uses a menu system. Arrows show the four directions to leave a menu box. Pressing a

corresponding keypad arrow will move to the next item in the direction shown. Move the cursor

(underline) under numerals and increase or decrease numerals with the and keys.

To store settings permanently (even through power interruptions), press ✓.

MAIN DISPLAY

The main display shows the units selected from the Units/Mode menu, Flow or

Velocity rate being measured, TOTALIZER and RELAY states. The UF AV5500

will start-up with this display.

MESSAGE ICON

Press from the main display to view temperature measurement, status of the

data logger and error/warning messages provided by the instrument. The

Message Icon will appear on the main display if error messages are being

generated by the instrument. Press ✓to return to the main display.

STATUS

Press from the MAIN display to view instrument status.

Level Displays the measured level in units selected in the

Units/Mode menu.

Velocity Displays the measured velocity in units selected in the

Units/Mode menu.

Flow Displays the flow rate in units selected in the

Units/Mode menu. The flow is calculated based on the

individual level and velocity data, and the channel

shape and size programmed in the Channel Setup menu.

Min Flow Displays a read-only value of the minimum flow cutoff.

Any flow rate measured below this Min Flow will be

displayed as 0 on the LCD display.

Signal Strength Displays the strength of the received Doppler velocity

signal on a 0-100% scale.

Signal Cutoff Displays a read-only value for signal cutoff. If the

Signal Strength is less than the Signal Cutoff, velocity

will be reported as 0. This setting may need to be

adjusted in case of unstable velocity measurements with

no water moving, or when high levels of industrial

noise are present. The Signal Cutoff can be adjusted in

the Calibration menu.

STATUS (cont.)

Echo Confidence Displays the confidence of level measurement received

from the QZ02L submerged sensor, or PZ15 level

sensor, on a 0-100% scale. This value is a reflection of

the percent of echoes received from pulses. Example: If

8 pulses are sent from the level sensor and only 4

echoes are received, Echo Confidence will report 50%.

This does not mean that the level is inaccurate, but

instead means the level reading could be susceptible to

a loss of reading should the conditions causing missed

pulses gets worse. Like an increase in solids or bubbles

in the flow steam.

24 HR LOG

Press from the MAIN display to view a formatted flow report from instruments

with a built-in data logger. Press to pan through Flow, Velocity and Level

summaries. Press to scroll down one day or repeatedly to scroll to a specific

date. Up to 365 days can be stored for Flow, Level, and Velocity. Newest date

will overwrite the oldest. Press ✓to return to the main display.

Inserting a USB drive into the meter while on this screen will transfer 24 HR Log

data to the USB drive in .csv format.

PASSWORD

The Password (a number from 0000 to 9999) prevents unauthorized access to the

Calibration menu.

From the Main Display press the key to get to Password. Factory default

password is 0000 and if it has not been changed, this screen will be bypassed

completely.

A new password can be stored by going to the Special Functions New Password

menu.

If a user password is required, press to place the cursor under the first digit and

or to set the number, then to the second digit, etc. Press or ✓to

proceed to the Menu Selections screen.
