Q45U Ultrasonic Sensors with Bipolar Discrete Outputs

Near and Far Sensing Limit Settings:
The Q45U features a single push button for programming of
sensing window near and far limits (Figure 1). See the
programming procedure on page 4.
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 an overloaded output.
• 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 outputs are conducting.
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.
Output Response Settings:
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 following functions:

ON/OFF Mode
Output: On = normally closed (output energizes when target is absent)
Off* = normally open (output energizes when target sensed)
2
Mode: On = HIGH/LOW (fill level control, see description, on page 3)
Off* = ON/OFF (output follows sensing action)

*Denotes factory settings.
NOTE: Response setting of 2 cycles, or higher, is recommended for optimum sonic and electrical noise immunity. Always use the
slowest acceptable response speed for your application. Single cycle update is only recommended for short range
(<50 cm) applications looking for a stationary target (i.e. reflector).
