Instruction Manual
• 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

Off* = Voltage output enabled
3 Loss of echo On = Min - Max Mode
Off* = Hold Mode
4 Min-Max On* = Default to maximum output value
Off = Default to minimum output value
