Note: Remove Cover from Control Module to check diagnostic lights.
1. PROBLEM: No water is delivered when Faucet is activated.
ND CATOR: f no LED lights illuminate:
CAUSE: No electricity is being supplied to Faucet.
SOLUT ON: 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). f no
voltage is detected, replace Transformer.
CAUSE: There is an electrical system malfunction.
SOLUT ON: Reset electrical system. Unplug Sensor Connection.
Disconnect power to circuit for ten (10) seconds. Reconnect.
ND CATOR: f the GREEN LED does NOT illuminate when power is
reconnected:
CAUSE: There is an electrical system malfunction.
SOLUT ON: Reset electrical system. Unplug Sensor Connection.
Disconnect power to circuit for ten (10) seconds. Reconnect.
CAUSE: The Control Module circuit is “dead.”
SOLUT ON: Replace ETF-450-A Control Module.
ND CATOR: f 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.
SOLUT ON: Open supply stop(s) completely.
CAUSE: Debris is clogging Solenoid Filter.
SOLUT ON: Shut off water supply. Remove, clean and reinstall Solenoid
Filter.
ND CATOR: f 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:
CAUSE: There is a direct short in the Solenoid or Solenoid Cable.
SOLUT ON: Replace with ETF-370-A Solenoid.
ND CATOR: f 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.
SOLUT ON: Reduce Sensor detection range.
CAUSE: Sensor is faulty.
SOLUT ON: Replace Sensor.
ND CATOR: f 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.
SOLUT ON: ncrease Sensor detection range.
CAUSE: Sensor is faulty.
SOLUT ON: Replace Sensor.
2. PROBLEM: Sensing Range is too short.
CAUSE: Extended Range Sensitivity is required.
SOLUT ON: Dip Switch number 4 should be in the “DOWN” (Extended
Range Sensitivity) position. ncrease range by adjusting Range
Potentiometer clockwise (yellow phillips screw in blue base).
3. PROBLEM: Faucet activates by itself (false triggers).
CAUSE: Sensor range is set too long.
SOLUT ON: Decrease range by adjusting Range Potentiometer
counterclockwise. f necessary, flip Dip Switch number 4 to
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.
SOLUT ON: Open supply stop(s) completely.
CAUSE: Debris is clogging Solenoid Filter.
SOLUT ON: Shut off water. Remove, clean, and reinstall Solenoid Filter or
install Solenoid Valve repair kit ETF-1009-A.
CAUSE: Solenoid is worn or faulty.
SOLUT ON: Rebuild with ETF-1009-A Solenoid Repair Kit or replace ETF-
370-A Solenoid.
CAUSE: Debris is clogging Faucet Aerator or Spray Head.
SOLUT ON:Shut off water. Remove Aerator or Spray Head (use Key if
required). 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.
SOLUT ON: Disconnect Solenoid. Reconnect Solenoid with water flow
toward the Faucet (see arrow on Solenoid).
CAUSE: Debris is clogging Solenoid.
SOLUT ON: Remove and clean Solenoid Operator. f necessary, rebuild
with ETF-1009-A Repair Kit.
CAUSE: Seat in Solenoid Valve body is damaged or pitted.
SOLUT ON: Replace with ETF-370-A Solenoid.
