OPERATION

1.) Invisible light rays are continually emitted from the faucet sensor.

2.) When the user’s hands come into range of the sensor’s detection zone, the beam is reflected back to the sensor’s reciever, and activates the solenoid valve.

Operating Water

Pressure:

10-125 psi 3.) After the user removes their hands, the absence of the reflected light closes the valve. The circuit automatically resets for the next user.

Operational Water

Temperature:

Aerator:

33°F to 140°F (1°C to 60°C)

1.5 GPM Vandal-Resistant (Standard)

4.) If an object remains in view continuously, the faucet will automatically shut off. The faucet will remain off until the object is removed. After the object is removed, the faucet functions normally.

IMPORTANT:

• All plumbing is to be installed in accordance with applicable codes and regulations.

• Water supply lines must be sized to provide an adequate volume of water to each fixture.

• Flush all water lines prior to valve installation to ensure proper operation. Particulates in the water can block small orifices within the valve which may result in continuous running.

• The use of toothed tools during installation or service of the faucet or its components may lead to premature failure.

Purge Features:

The purge switches can be configured for 4 modes of operation: Disabled (standard configuration), 12 hour, 24 hours, or 48 hours.

Purge water flow duration is 2 minutes. Note: Purge activation occurs every switch selected time (0,12, 24, or 48 hours) after last activation.

Flow Time:

There are 6 optional time configurations: 30 seconds (standard), 5s, 10s, 15s, 60s, & “Less Time-out”. The “Less or No Time-out” option actually ceases water flow (turns off) after 20 minutes to limit chance of water damage in the event a sink drain becomes blocked .

Sensing Mode (DEFAULT):

During this mode the valve will shut off after hands are removed. If hands are not removed the time out delay will turn off the faucet

(ex: standard configuration is 30 seconds)) (See Sensing & Metering Mode flow chart on following page)

Metering Mode:

When hands are detected by the sensor, water will run for ‘ X’ seconds (standard configuration is 30 seconds) before turning off.

(See Sensing & Metering Mode flow chart on following page)

Sensor Sensitivity: (Default setting: Low):

There are 4 sensitivity options, which can be selected to achieve the optimal detection performance related to the sink material, shape, & finish. The faucet sensor sensitivity is configured during pack-out but the mode can be changed upon installation to optimize the performance within the sink. Sensor sensitivity and Modes A & B may be tried for difficult sink materials and shape.

NOTE: After a configuration switch change has been made, disconnect sensor cable from electronics box, wait 30 seconds, then reconnect sensor cable and wait 30 seconds to allow the sensor to tune-in the sink characteristics.

TROUBLESHOOTING GUIDE:

POTENTIAL SITUATIONS

Sensor faucet is not activating or running

POSSIBLE CAUSES

Battery voltage low or no pow er

SUGGESTED SOLUTION TIPS

Change out batteries or verify pow er provided by HW6 or ACA

If faucet is hardw ired, voltage may be out of allow able range.

Contamination in battery tray causing a voltage drain

Sensor and electronic connector cable has bent or broken pins

Sensor lens could have surface damage,

Check voltage levels and verify w ithin recommended ranges.

Remove the battery tray and inspect for visual signs of rust, w ater, debris. Replace battery tray if these symptoms are found.

Check to see if pins are missing, bent, or broken. If yes, then the electronic box needs replaced

Inspect the sensor lens underneath the spout tip. May require cleaning w ith a damp cloth or sensor replacement scratches, or deposit build ups from chemical cleaners

Sensor lens could be obstructed by environmental factors such as high reflective surfaces or bright lighting conditions

If this is the case, then adjust the dip sw itch settings for sensor sensitivity per the diagram on previous page (sw itches 7 and 8).

Direct sunlight into bow l may make the unit inoperable. Do not allow direct sunlight into bow l

Solenoid is not connected properly

Solenoid is lodged w ith debris or plunger is sticking

Place hands in sensor range. If clicking occurs, solenoid is connected correctly. If no clicking occurs, disconnect the sensor cable from the black box and w ait 30 sec before reconnecting.

Once reconnected try activating again.

Check solenoid for debris and clean if necessary and reassemble

Sensor faucet does not activate after initial installation

Sensor may not have had enough time to calibrate prior to a user or target trying to initiate activation

Disconnect the sensor and electronic box cables and w ait for 30 seconds. Reconnect the cables, but allow for another 30 seconds before placing hands or a target w ithin the sensor range. You should hear a click of the solenoid once calibration is complete.

Faucet runs continuously

(longer than the selected timeout that is programmed)

Solenoid is lodged w ith debris

Electronics box cable connector has bent pins that are shorted

Check solenoid for debris and clean if necessary and reassemble

Check to see if pins are missing, bent, or broken. If yes, then the electronic box needs replaced.

Sensor faucet is experiencing random activations w hen a user or target is not w ithin sensing range

Sensor lens could be obstructed or environmental factors such as high reflective surfaces and/or bright sunlight conditions

Change dip sw itch settings (sw itches 7 &8) for sensor sensitivity per the diagram and allow 15s for calibration to occur.

Loosen the mounting nuts and try sliding the faucet back in the lavatory, sink, or counter top holes back tow ards the w all and retightening. Could be detecting the grid drain in the sink bow l. After repositioning faucet, recalibrate sensor by unplugging & replugging cable

Sensor faucet is leaking underneath the sink or counter

Mounting hardw are is not tightened sufficiently (faucet shank, electronic box, supply hoses, etc)

Missing the w asher located in the solenoid box nut w here it assembles to the faucet shank.

Check and ensure the nuts and joints are tight and secure from the supply stop all the w ay to the faucet shank.

Make sure the w ater supply stops are shut off. Check to ensure the w asher is installed or damaged. If not, install w asher. If a w asher is installed replace w ith new .
