Standard 2 m (6.5 ft) cable models are listed. To order the 9 m (30 ft) cable model, add suffix "W/30" to the cabled model number. For
example, Q45ULIU64BCR W/30. Models with a QD connector require a mating cable.

WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to serious
injury or death. This device does not include the self-checking redundant circuitry necessary to allow its

use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de­energized sensor output condition.

milliseconds to 2.56

Temperature Compensation

All models listed above feature temperature compensation. An increase in air temperature shifts both sensing window limits closer to the
sensor. Conversely, a decrease in air temperature shifts both limits further away from the sensor. The shift is approximately 3.5% of the
limit distance for a 20 °C change in temperature.

Temperature compensated models maintain the position of both sensing window limits to within 1% of each limit distance over the 0 to
+50 °C range, and to within 2.5% over the full operating range of from –25 to +70 °C.

Setting the Near and Far Sensing Limits

The Q45U features a single push button for programming of sensing window near and far limits. For more information, refer to Program-

ming the Window Limits on page 4.

Status Indicators

Status indicator LEDs are visible through the transparent, o-ring sealed acrylic top cover. Indicator function in the Run mode is, as fol­lows:

Q45U Ultrasonic Sensors with Analog Outputs (Long Range)

• The green LED is solid when power is applied to the sensor and flashes to indicate a current output fault.

• The red LED is solid when an echo is received and flashes at a rate proportional to echo strength.

• The amber LED is solid when the target is within the operating window limits.

The 5-segment moving dot LED indicator displays the relative position of the target within the programmed sensing window. LED #1
flashes when the target is closer than the near limit. LED #5 flashes when the target is beyond the far limit.

Output Response Settings

Important: Remove power before making any internal adjustments.

Using the two slots shown in Figure 1. Analog Q45U Features on page 2, a small flat-blade screwdriver may be used to lift up and
remove the black inner cover to expose the 4-position DIP switch. Use these DIP switches to program the output slope, output mode,
loss of echo, and min./max. output value default.

DIP Switch Function Settings

1 Output slope On = Output value increases with distance

Off* = Output value decreases with distance

2 Output mode On = Current output enabled

Off* = Voltage output enabled

3 Loss of echo On = Min - Max Mode

4 Min-Max On* = Default to maximum output value

Off* = Hold Mode

Off = Default to minimum output value

* Factory default setting.

Figure 3. Output as a function of target position

On = Direct = Output value (voltage or current) increases with in­creasing distance of the target from the sensor

Off* = Inverse = Output value decreases with increasing distance
of the target from the sensor

DIP Switch 2: Output Mode Select

On = The 4 to 20 mA current output (white wire) is enabled

Off* = The 0 to 10V dc voltage output (black wire) is enabled

This switch configures the D/A driver to use either the current output or the voltage output driver. This output function can only be set with
the power to the sensor turned off.

DIP Switch 3: Loss of Echo Mode Select

On = Min - Max Mode

Off* = Hold Mode

This switch determines the output response to the loss of echo. The “Hold Mode” (Switch 3 Off*) maintains the output at the value
present at the time of echo loss. The “Min - Max Mode” (Switch 3 On) drives the output to either the minimum value (0V or 4 mA or the
maximum value (10V or 20 mA) when the echo is lost. Minimum or maximum value is selected by DIP switch 4.

DIP Switch 4: Min-Max Default

On* = Default to maximum output value at loss of echo

Off = Default to minimum output value at loss of echo

Switch 4 selects the output response to loss of echo when “Min - Max Mode” is selected by DIP switch 3.

Response Speed Adjustments

The speed of the output response is set using the single-turn potentiometer. There are six values for response speed, which relate direct­ly to the number of sensing cycles over which the output value is averaged. The response value is set by aligning the slot of the potenti­ometer with one of the marked positions.

Programming the Window Limits

Use the “Limits” push button, located under the transparent top cover, to program the near and the far limits. The near limit may be set as
close as 250 mm (9.8 inches) and the far limit may be set as far as 3.0 m (118 inches) from the transducer face. Minimum window width
is 25 mm (1 inch). Whenever possible, use the actual target to be sensed when setting the window limits. The following procedure begins
with the sensor in Run mode.

Step Description LED Indicator Status

1 Access Limit Programming Mode. Push and hold until the

green indicator LED turns off (approximately 2 seconds).

2 Set the First Limit (Near or Far). Place the target at the

first limit and press the push button for less than 2 sec­onds.

Green: Goes off

Amber: Solid on to indicate ready for teaching first limit

Red: Flashes to indicate strength of echo or is off if no target is
present

Green: Remains off

Amber: Flashes at 2 Hz to indicate ready for teaching second
limit

Red: Solid on for a moment, then resumes flashing to indicate
strength of echo

3 Set the Second Limit (Far or Near). Place the target at the

second limit and press the push button for less than 2 sec­onds

Notes Regarding Window Limit Programming

1. Either the near or far limit may be programmed, first.

2. There is a 2-minute time-out for programming of the first limit. The sensor will return to Run mode with the previously programmed
limits. There is no time-out between programming of the first and second limit.

3. The programming sequence may be cancelled at any time by pressing and holding the push button for ≥ 2 seconds. The sensor
returns to Run mode with the previously programmed limits.

4. During limit programming, the 5-segment moving dot indicator displays the relative target position between 0 and 4.0 m (the maxi­mum recommended far limit position is 3.0 m (118 inches)).

5. If the target is positioned between 3.0 m (118 inches) and 4.0 m, the 5th segment of the moving dot indicator flashes to indicate
that a valid echo is received, but the target is beyond the recommended 3.0 m (118 inches) maximum far limit.

6. If a limit is rejected during either programming step, the sensor will revert to the first limit programming step (Step 2 in programming
chart). This will be indicated by Green - off, Red - flashing to indicate signal strength, and Amber - solid on.

7. If both limits are accepted, the sensor will return to Run mode, which is indicated by the solid on Green LED.

4 www.bannerengineering.com - tel: [phone] P/N 48456 Rev. E

Green: Remains off, then comes on solid (returns to Run mode)

Amber: Solid on for a moment, then is either on or off to indi­cate output state (returns to Run mode)

Red: Solid on for a moment, then resumes flashing to indicate
strength of echo (returns to Run mode)

Q45U Ultrasonic Sensors with Analog Outputs (Long Range)

8. If the target is held at the same position for programming of both limits, the sensor will establish a 50 mm-wide sensing window,
centered on the target position.

Remote Programming the Window Limits

Connect the yellow wire of the Analog Q45U to a switch or process controller for remote programming of the sensing window limits. The
programming procedure is the same as for the push button. A remote programming input is generated when +5 to 24V dc is applied to
the yellow wire. The timing diagrams, below, define the required input pulses.

H = +5 to 24V dc
