INSTALLATION AND REPLACEMENT
1. Disconnect 24 VAC power supply at the transformer or the fusebox.
2. Remove the Cover Plate and old Sensor from the wall installation. Use a
5/64" hex wrench to remove the Cover Plate Screws.
3. Connectone24VACleadtotheSensorterminallabeled“24VACIN.”(See
Figure 2.)
• On an old three-wire EL-150 series Sensor, this wire was connected to
the BLACK Sensor lead.
• On an old four-wire EL-150 series Sensor, this wire was connected to
the BROWN Sensor lead.
4. Connect one Solenoid lead to the Sensor terminal labeled “TO VALVE.”
(See Figure 2.)
• On an old three-wire or four-wire EL-150 series Sensor, this wire was
connected to the RED Sensor lead.
5. Connect the remaining 24 VAC lead to the remaining Solenoid lead.
• Onan oldthree-wire EL-150seriesSensor, thesewireswere connected
to the WHITE Sensor lead.
• On an old four-wire EL-150 series Sensor, these wires were connected
to the YELLOW and BLUE (or in very early models, the inner BROWN)
Sensor leads.
6. On Water Closet installationsonly, connectthe OverrideButton (shown as
the Override Switch in Figure 1 Wiring Diagram) parallel to the EL-1500-L
Sensor.
7. The illustration of the Sensor on the front cover of these installation
instructions shows an orientation arrow on the Lens side of the Sensor.
Reinstall the Sensor with the arrow pointing UP. Replace the Cover Plate
and tighten the Cover Plate Screws.
8. Reconnect the 24 VAC power supply at the transformer or the fusebox.
START-UP MODE
The self adaptive sensor automaticallyadapts to thesurrounding environment
when 24 volt supply is activated.No manual adjustments are required.
Start-upmode willtakeapproximatelyfive(5) minutestocomplete itscycleand
is important that no non-permanenttarget is present at thistime. A continuous
redlightvisibleinsensorwindow indicatessensorisinthe start-upmode. Ifthe
red light isflashing, thisindicates that thesensor is pickingup a target.Unless
thistarget isa permanentfixtureinthe sensor’senvironment(i.e.,a wallorstall
door),itmustberemovedfromtheviewofthesensor.Ifthistargetispermanent,
the sensor will adapt itself around this target. In this case, the start-up mode
may take up to ten (10) minutes. When the start-up cycle is completed, there
will be no light visible in the sensorwindow.
Note: If the 24 voltpower supply isever interrupted for longerthan fifteen(15)
seconds, the start-up mode automaticallybegins when power is restored.
