Adjustments

The following may be selected by a 4-position DIP switch.

Discrete: Switch 1: Output normally open/normally closed (pump in/pump out)

Switch 2: High/Low level control mode or ON/OFF presence sensing mode

Switch 3 & 4: Response speed selection (digital lter)

Analog: Switch 1: Output slope positive or output slope negative

Switch 2: Current output mode or voltage output mode

Switch 3: Loss of echo min/max mode or loss of echo Hold Mode

Switch 4: Loss of echo min/max default output value

Indicators

Discrete: Three status LEDs:

Green: power ON

Yellow: outputs are conducting (Yellow LED also indicates programming

status during setup mode)

Red: indicates relative strength of received echo

Analog: Three status LEDs:

Green: power ON

Yellow: target is sensed within the window limits (Yellow LED also indicates programming status during setup mode)

Red ﬂashing: indicates relative strength of received echo

5-segment moving dot LED indicates the position of the target within the sensing window.

See data sheet for detailed information.

Construction

Molded PBT polyester thermoplastic polyester housing, o-ring sealed transparent acrylic top cover, and stainless steel hardware.

Q45U sensors are designed to withstand 1200 psi washdown. The base of cabled models has a ½"-14NPS internal conduit thread.

Environmental Rating

Leakproof design is rated IEC IP67; NEMA 6P

Connections

2 m or 9 m attached cable, or 5-pin Mini-style or 5-pin Euro-style QD fitting. QD cordsets are ordered separately. See pages 335.

Operating Conditions

Temperature: -25° to +70° C Relative humidity: 100%

Vibration and

Mechanical Shock

All models meet Mil. Std. 202F requirements. Method 201A (Vibration: 10 to 60Hz max., double amplitude 0.06",

maximum acceleration 10G). Method 213B conditions H & I (Shock: 75G with unit operating; 100G for non-operation). Also meets

IEC 947-5-2 requirements: 30G, 11 milliseconds duration, half sine wave.

Application Notes

Short Range: Min. target size: 10 x 10 mm aluminum plate at 500 mm

35 x 35 mm aluminum plate at 1.4 m

Long Range: Min. target size: 50 x 50 mm aluminum plate at 3 m

Discrete: Enable/Disable; Connect yellow wire to +5 to 24V dc to enable sensor and 0 to +2V dc to disable sensor. When the sensor

is disabled, the last output state is held until the sensor is re-enabled. The wire must be held to the appropriate voltage for at least 40

milliseconds for the sensor to enable or disable.
