DIP Switch Selectable Functions
CAUTION: To avoid damage to the sensor caused by static discharge (ESD), observe proper ESD
precautions (grounding) while adjusting the DIP switches.
Switch 1: Output Mode Select
ON = 4 to 20 mA current output is enabled
OFF = 0 to 10 V dc voltage output is enabled
Switch 1 configures the sensor internally to use either the current output or voltage output configuration.
Switch 2: Loss of Echo Mode Select
ON = Min-Max Mode
OFF = Hold Mode
Switch 2 determines the output response to the loss of echo. “Min-Max Mode” (Switch 2 ON) drives the output to either
the minimum value or the maximum value when the echo is lost. (Minimum or Maximum value is selected via Switch 3.)
“Hold Mode” (Switch 2 OFF) maintains the output at the value which was present at the time of echo loss.
Switch 3: Min-Max Default
ON = Default to maximum output value at loss of echo (10.5 V dc or 20.8 mA)
OFF = Default to minimum output value at loss of echo (0 V dc or 3.6 mA)
Switch 3 selects the output response to loss of echo when “Min-Max Mode” is selected via Switch 2. When Switch 2 is OFF,
Switch 3 has no function.
Switch 4: Teach/Transmit Enable Control
ON = Gray (or yellow) wire configured for remote teach
OFF = Gray (or yellow) wire configured for transmit enable/disable: High (5 to 30 V dc) - Transmit Enabled (Power LED
solid Green); Low (0 to 2 V dc) - Transmit Disabled (Power LED flashes at 2 Hz)
When Switch 4 is ON, the gray wire is used to teach window limits to the sensors.
When Switch 4 is OFF, the gray wire is used to enable and disable the sensor’s transmit burst. The sensor output will react
as if a “loss of echo” occurred and either hold the output or change to minimum or maximum value (depending on switch 2
and 3 settings). This function may be used when multiple sensors are in close proximity, which may make them vulnerable
to crosstalk interference. A PLC can be used to enable the sensors one at a time to avoid crosstalk.
