Features
•Analog Output Card plugs into any Q45U ultrasonic proximity mode sensor in place
of the existing output card.
•Selectable 0 to 10V dc voltage-sourcing or 4 to 20 mA current-sourcing analog
outputs
•Selectable output slope: positive or negative as target distance increases
Installing the 45LMA Card
Use the following procedure to install the 45LMA Analog Output Card:
1) Remove power from the Q45U sensor.
2) Remove the output card from the Q45U sensor (Figure 1). Use a small
screwdriver, or similar tool, to dislodge the output card from its connector.
Then, slide the card out of the sensor.
3) Slide the 45LMA card into the sensor in place of the sensor output card
(Figure 3); push it firmly into place.
4) Configure DIP switches as necessary. See programming instructions and table for
information.
5) Apply power to the sensor.

Programming the 45LMA Card
Status Indicators:
Status indicator LEDs are visible through the transparent, o-ring sealed Lexan®top
cover. Indicator function in the RUN mode is, as follows:
•The green LED is on steadily whenever power is applied to the sensor, and flashes
to indicate a current output fault.
•The red LED lights when an echo is received, and flashes at a rate that is
proportional to echo strength.
•The yellow LED lights whenever 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. The #1 LED flashes when the target is
closer than the near limit. The #5 LED flashes when the target is beyond the far limit.

small screwdriver to dislodge it
from its connector.

sensor and push it firmly into

IMPORTANT: Remove power before making any internal adjustments.
Using the two slots shown in Figure 1, a small flat-blade screwdriver may be used to lift
up and remove the black inner cover to expose the 4-position DIP switch (Figure 2).
Those switches are used to program the functions as indicated in Figure 4.

Explanation of Programmable Output Functions:
Switch 1: Output Slope Select
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
Switch 2: Output Mode Select
On = The 4 to 20mA 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.
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 which was present at the time of
echo loss. The “Min - Max Mode” (Switch 3 On) drives the output to either the
minimum value (0V or 4mA or the maximum value (10V or 20mA) when the echo is
lost. Minimum or maximum value is selected by Switch 4.
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 Switch 3 (see above).
Response Speed Adjustment
The speed of the output response is set using the single-turn potentiometer (see
Figures 1 and 6). 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.
The positions and their corresponding settings are identified in Figure 6.
