OPTIMA EHD Electronic Hand Dryer Fiber Optic

OPTIMA EHD Electronic Hand Dryer Fiber Optic
TROUBLESHOOTING GUIDE
NOTE: Each power board has two (2) LEDs: a green power
indicator and a red sensor indicator. Electrical power must
be supplied to Hand Dryer for indicator lights to function.
If none of the solutions shown below works, the
power board may need to be reset; disconnect
then reconnect electrical power and retest.
No air is supplied when hands are placed in Sensor's
detection zone.
Remove cover and check LED indicator lights on
the Power Board.
If green LED does NOT illuminate:
• Power is not being supplied to dryer; check all
electrical connections and main power supply.
• Power Board has failed; replace.
If green LED illuminates first and then red LED
illuminates when hands are placed in the Sensor's
beam:
• Blower Motor is not connected properly; check
Blower Motor leads for secure connection.
• Power Board has failed; replace.
• Blower Motor has failed; replace.
If green LED illuminates first, but red LED does
NOT illuminate when hands are placed in the
Sensor's beam:
• Power Board or Power Board detection circuit
has failed; replace.
If only the red LED illuminates (green LED does
NOT illuminate when hands are removed from the
Sensor's beam):
• Power Board or Power Board self-calibration
circuit has failed; replace Power Board.
• OPTIMA Sensor has failed; replace.
Only unheated air is supplied when hands are placed in
the Sensor's beam.
• Heater is not properly connected; check Heater
leads for secure connection.
• Heater Assembly is defective; replace.
Air cycles intermittently on and off.
• The Power Board's range feature is not functioning properly; replace Power Board.
Dryer runs continuously (will not stop).
Disconnect OPTIMA Fiber Optic Cable from Fiber
Optic Connector on the Power Board.
• If dryer keeps running, the Power Board has
failed; replace.
• If dryer stops running, the OPTIMA Sensor has
failed; replace.

Older Sloan EHD Hand Dryers
Sloan Valve Company is dedicated to providing sensoroperated products that incorporate today's latest electronic
technologies. To keep pace with these new technologies it is
often necessary to make changes to our products. Current
EHD Hand Dryer Power Boards and OPTIMA Fiber Optic
Sensors will operate in older Sloan EHD Hand Dryers if the
following conditions are met:
• Hand dryers built between September 1995 and June 1999
used Power Board Assemblies EHD-1004-A (120 VAC) and the
EHD-1005-A (208/240 VAC) and OPTIMA Sensor Assembly
EHD-1003-A. These units can be identified by a Range
Potentiometer located on the Power Board.
• Hand dryers built before September 1995 used Power Boards
EHD-12-A (120 VAC) and EHD-65-A (208/240 VAC) and OPTIMA Sensor EHD-234-A (EHD-13-A if built before 1991). These
units can be identified by a Range Potentiometer located on the
OPTIMA Sensor (NOT on the Power Board).
IF EITHER THE POWER BOARD OR THE OPTIMA SENSOR HAS FAILED IN AN
OLDER UNIT, BOTH COMPONENTS MUST BE REPLACED.
Note: Hand Dryers built before 1991 included a flashing indicator light
visible through a window on the Hand Dryer Cover. Replacement covers
no longer furnish the indicator light; therefore disconnect and remove the
light if replacing the Cover or OPTIMA Sensor.
LIMITED WARRANTY
Sloan Valve Company warrants its products to be made of first class materials,
free from defects of material or workmanship under normal use and to perform the service for which they are intended in a thoroughly reliable and efficient manner when properly installed and serviced for a period of 5 years
from date of purchase.
EHD-1006-A Hand Dryer Repair Kit, 120 VAC (Code no. 3366007)
EHD-1007-A Hand Dryer Repair Kit, 208/240 VAC (Code no. 3366008)
OPERATION
The Sloan Electronic Hand Dryer operates by means of an adaptive fiber optic sensory
device. The Sensor automatically activates the unit when hands are placed in front of the
Sensor located at the exhaust port. A powerful flow of warm air dries hands in approximately thirty (30) seconds and stops automatically two (2) seconds after hands are withdrawn, or after a maximum of sixty (60) seconds of continuous operation.
1. The OPTIMA EHD functions by means of an electronic Fiber Optic Sensor located at the
exhaust port beneath the Hand Dryer.
2. When the Fiber Optic Sensor detects hands beneath the exhaust port, it activates the
Hand Dryer. A powerful flow of warm air dries hands within thirty (30) seconds.
3. After hands are withdrawn from the Sensor's detection zone, the Hand Dryer automatically stops. It is then
ready for the next user.
SELF-ADAPTIVE FIBER OPTIC SENSING
When this Hand Dryer powers up, it automatically sets its sensing range depending on the environment in which it is
installed. No mechanical range adjustment is required.
NOTE: Older Sloan Hand Dryers had an adjustable Sensor range feature. This feature is not required with the current
adaptive Sensor. For more information on older Hand Dryer designs, see back page.
INSTALLATION
ALL ELECTRICAL WIRING SHOULD BE INSTALLED IN ACCORDANCE WITH NATIONAL/LOCAL CODES AND REGULATIONS.
STEP 1 - ELECTRICAL DISCONNECTION
Before installing the replacement Power Board and Grille/Fiber Optic Cable Subassembly, be certain that the power
supply to Hand Dryer is disconnected at the main power source.
STEP 2 - REMOVE COVER ASSEMBLY
Remove Cover from Chassis Assembly by removing four (4) tamper-resistant Cover Screws and Lock Washers. Use a
5/32" hex wrench to remove the Cover Screws. Set the screws and washers aside to reinstall the Cover Assembly in
Step 10.
STEP 3 - DISCONNECT OLD POWER BOARD ASSEMBLY
During this period, Sloan Valve Company will, at its option, repair or replace
any part or parts which prove to be thus defective if returned to Sloan Valve
Company, at customer’s cost, and this shall be the sole remedy available under
this warranty. No claims will be allowed for labor, transportation or other incidental costs. This warranty extends only to those persons or organizations who
purchase Sloan Valve Company’s products directly from Sloan Valve Company
for purpose of resale.
NOTE: The OPTIMA Power Board is located on the right side of the Blower Assembly.
Disconnect wires from the old Power Board leading to the power source, the Blower Assembly, and the Heater
Assembly (refer to appropriate wiring diagram for 120 VAC or 208/240 VAC unit). Remove Power Board Mounting
Nuts holding Power Board to Chassis Assembly and set aside. These nuts will be used to install the new Power Board
Assembly in Step 5.
THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION ON
THE FACE HEREOF. IN NO EVENT IS SLOAN VALVE COMPANY RESPONSIBLE FOR
ANY CONSEQUENTIAL DAMAGES OF ANY MEASURE WHATSOEVER.
STEP 4 - REMOVE OLD OPTIMA SENSOR
