|
| Adjustments | The following may be selected by a 4-position DIP switch located on top of the sensor, beneath a transparent o-ring sealed acrylic cover:
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 filter)
|
| Indicators | 5-segment moving dot LED indicates the position of the target within the sensing window
3 LED indicators:Green, Yellow and Red
Green ON steady:power to sensor is ON
Green flashing:output is overloaded
Yellow ON steady:outputs are conducting (RUN mode) and programming status (SETUP mode)
Red flashing:indicates relative signal strength of received echo
|
| Construction | Molded PBT 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 1/2 inch-14NPS internal conduit thread
|
| Environmental Rating | Leakproof design, rated IEC IP67; NEMA 6P
|
| Connections | 5-conductor 2 m or 9 m shielded PVC-jacketed attached cable, or 5-pin Euro- or Mini-style quick-disconnect fitting. QD cables are ordered separately.
|
| 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 60 Hz 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 | 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.
