1. A continuous, invisible light
beam is emitted from the
OPTIMA Sensor.
2. When a user enters the
beam’s effective range, the
beam is reflected into the
OPTIMA’s scanning window
and transformed into a low
voltage electrical signal
that activates a ten-second
time delay circuit. The time
delay circuit eliminates false
operation from passers-by
in the rest room. Once the
time delay is completed,
the output circuit is alerted
and continues in a “hold”
mode for as long as the user
remains within the effective
range of the sensor.
3. When the user steps away
from the OPTIMA Sensor,
the loss of reflected light
initiates an electrical “one-
time” signal that energizes
the Solenoid Operator, and
activates the Flushometer
to flush the fixture. This
occurs approximately three
(3) seconds after indication.
This delay is built into the
Sensor to help prevent false
flushing due to movement
by the user. The circuit then
automatically resets and is
ready for the next user.

OPERATION
TROUBLESHOOTING GUIDE
NOTE: Upon detection of the user, the red indicator light is steadily on for a period of eight seconds. When the user
leaves the detection range, the indicator light will turn off and the Sensor initiates the flush sequence. Then the
indicator light stops flashing and the valve flushes. The valve will flush after a three-second delay.
1. PROBLEM: Valve does not function (red light does not
turn on when user steps in front of sensor).
CAUSE: No power is being supplied to sensor.
SOLUTION: Ensure that the main power is turned “ON.” Check
transformer, leads and connections. Repair or replace as
necessary.
CAUSE: Sensor is not operating.
SOLUTION: Replace Sensor.
2. PROBLEM: Valve does not function (red light flashes
when user steps in front of Sensor).
INDICATOR: Red light stops flashing when user steps away
and valve makes a “clicking” sound but does
not flush.
CAUSE: No water is being supplied to the valve.
SOLUTION: Make certain that water supply is turned “ON” and the Control
Stop is open.
CAUSE: EL-128-A cartridge is fouled or jammed.
SOLUTION: Turn electronic power to valve “OFF” (failure to do so could
result in damage to the solenoid coil). Remove the solenoid
operator from the valve and remove the
EL-128-A cartridge. Clean and/or repair as necessary.
INDICATOR: The red light does not turn off when user
steps away and the valve does NOT make a
“clicking” sound and does NOT flush.
CAUSE: EL-163-A solenoid shaft assembly is fouled or
jammed.
SOLUTION: Turn electronic power to valve “OFF” (failure to do so could
result in damage to the solenoid coil). Remove
EL-101 or EL-166 nut from the solenoid operator. Remove
the coil from the solenoid operator. Use a spanner wrench or
pliers to remove the EL-163-A solenoid shaft assembly from
valve. Clean and/or replace as necessary. Be sure to replace
plunger spring when reassembling Solenoid Shaft Assembly.
3. PROBLEM: Volume of water is insufficient to adequately
siphon fixture.
CAUSE: Control Stop is not open wide enough.
SOLUTION: Adjust control stop for desired water delivery.
CAUSE: Low Consumption unit is installed on Water
Saver or Conventional fixture.
SOLUTION: Replace Diaphragm component parts of valve with kit that
corresponds to appropriate flush volume of fixture.
CAUSE: Inadequate water volume or pressure
available from supply.
SOLUTION: Increase pressure or supply (flow rate) to the valve. Consult
factory for assistance.
4. PROBLEM: Length of flush is too long (long flushing) or
valve fails to shut off.
CAUSE: Water Saver valve is installed on Low
Consumption fixture.
SOLUTION: Replace Diaphragm component parts of valve with kit that
corresponds to appropriate flush volume of fixture.
CAUSE: Relief valve in diaphragm is not seated
properly or bypass hole in diaphragm is
clogged.
SOLUTION: Disassemble inside Diaphragm component parts and wash
parts thoroughly. Replace worn parts if necessary.
5. PROBLEM: Water splashes from fixture.
CAUSE: Supply flow rate is more than necessary.
SOLUTION: Adjust Control Stop to meet flow rate required for proper
cleansing of the fixture.
