SENSOR FAUCETS
PP aa rr tt ss GG uu ii dd ee
•24 VAC HARDWIRE FAUCETS
1. PROBLEM: No water is delivered when faucet is activated.
INDICATOR: If no LED lights illuminate:
CAUSE: No electricity is being supplied to faucet.
SOLUTION: Ensure that the main power is turned “ON”. Check all
transformer, sensor, solenoid and cable connections.
Make sure that transformer is supplying 24 VAC (Volts
AC). If no voltage is detected, replace transformer.
CAUSE: There is an electrical system malfunction.
SOLUTION: Reset electrical system. Unplug Sensor connection.
Disconnect power to circuit for ten (10) seconds.
Reconnect.
INDICATOR: If the GREEN LED illuminates when power is reconnected:
CAUSE: There is a short in the Sensor.
SOLUTION: Replace Sensor. Refer to individual faucet parts diagram
for appropriate Sensor Assembly.
Note: GREEN LED may illuminate immediately after Sensor disconnection.
CAUSE: There is a short in the Solenoid or Solenoid cable.
SOLUTION: Replace ETF-370-A Solenoid.
INDICATOR: If the GREEN LED does NOT illuminate when power is reconnected:
CAUSE: There is an electrical system malfunction.
SOLUTION: Reset electrical system. Unplug Sensor connection.
Disconnect power to circuit for ten (10) seconds.
Reconnect.
CAUSE: The Control Module circuit is “dead”.
SOLUTION: Replace ETF-450-A Control Module.
INDICATOR: If GREEN LED illuminates AND changes to RED when hands are in
the Sensor’s detection zone AND the RED Solenoid LED illuminates:
CAUSE: Water supply stop(s) may be partially closed.
SOLUTION: Open stop(s) if closed.
CAUSE: Debris is clogging Solenoid Filter.
SOLUTION: Shut off water supply. Remove, clean and reinstall
Solenoid Filter.
INDICATOR: If GREEN LED illuminates AND changes to RED when hands are
placed in the Sensor’s detection zone AND the RED Solenoid LED
flickers with a vibrating/clicking noise heard inside the module:
Note: Applies only to REVISION 2 MODULES.
CAUSE: There is a direct short in the Solenoid or Solenoid cable.
SOLUTION: Replace with ETF-370-A solenoid
INDICATOR: If green/red LED illuminates AND changes to RED when hands are
NOT located in the Sensor’s detection zone BUT the red Solenoid
LED (in upper left corner of circuit) does NOT illuminate:
CAUSE: Sensor range is set too long and is detecting the sink.
SOLUTION: Reduce Sensor detection range.
CAUSE: Sensor is faulty.
SOLUTION: Replace Sensor. Refer to individual faucet parts diagram
for appropriate Sensor Assembly.
INDICATOR: If green LED illuminates BUT does NOT change to red when
hands are placed in the Sensor’s detection zone:
CAUSE: Sensor range is set too short.
SOLUTION: Increase Sensor detection range.
CAUSE: Sensor is faulty.
SOLUTION: Replace Sensor. Refer to individual faucet parts diagram
for appropriate Sensor Assembly.
2. PROBLEM: Sensing Range is too short.
CAUSE: Extended Range Sensitivity is required.
SOLUTION: Dip Switch number 4 should be in the “DOWN”
(Extended Range Sensitivity) position. Increase range by
adjusting range potentiometer clockwise (yellow phillips
screw in blue base).
CAUSE: Faucet has Surgical Bend Gooseneck Spout.
SOLUTION: For Long Range use (recommended for Surgical Bend
Gooseneck Spout faucet models), remove Range Jumper
from upper right hand corner of circuit board. Adjust
range potentiometer.
Note: Applies only to REVISION 2 MODULES.
3. PROBLEM: Faucet activates by itself (false triggers).
CAUSE: Sensor range is set too long.
SOLUTION: Decrease range by adjusting range potentiometer
counterclockwise. If necessary, flip Dip Switch number 4
into the “UP” (Reduced Range Sensitivity) position.
Check surroundings for factors that contribute to Sensor
range detection problems (bright lights, highly reflective
surfaces, sunlight, etc.).
4. PROBLEM: Faucet delivers very low flow or just a dribble.
CAUSE: Water Supply Stop(s) may be partially closed.
SOLUTION: Open stop(s).
CAUSE: Debris is clogging Solenoid Filter.
SOLUTION: Shut off water. Remove, clean, and reinstall Solenoid
Filter.
CAUSE: Solenoid is worn or faulty.
SOLUTION: Rebuild with ETF-1009-A Solenoid Repair Kit or replace
ETF-370-A Solenoid.
CAUSE: Debris is clogging faucet Aerator or Spray Head.
SOLUTION: Shut off water. Use Key if required to remove. Then clean
and reinstall Aerator or Spray Head.
5. PROBLEM: Faucet does not stop delivering water or continues to
drip after user is no longer detected (even after power
to the Module has been disconnected).
CAUSE: Solenoid Valve is installed backward.
SOLUTION: Disconnect Solenoid. Reconnect Solenoid with water
flow towards the faucet (see arrow on Solenoid).
CAUSE: Debris is clogging Solenoid.
SOLUTION: Remove and clean Solenoid operator. If necessary,
rebuild with ETF-1009-A Repair Kit.
CAUSE: Seat in Solenoid valve body is damaged or pitted.
SOLUTION: Replace with ETF-370-A solenoid.

NOTE: Revision 2 ETF-450-A Control Modules (manufactured after April 1999) have built-in reset fuses to protect the circuitry if a sensor or solenoid fails or shorts. In
earlier models, a sensor or solenoid short or failure could also result in an ETF-450-A Control Module failure.

Care and Cleaning Instructions:
DO NOT USE abrasive or chemical cleaners to clean Faucets that may dull the luster and
attack the chrome or special decorative finishes. Use ONLY soap and water, then wipe dry with a clean towel or cloth. When cleaning the
bathroom tile, protect the Faucet from any splattering of cleaner. Acids and cleaning fluids can discolor or remove chrome plating.
