 MultimeterTest for breaks in wire/ Test for voltageMost appliance require 80% rated voltage to function correctly Buy Multimeters at Amazon Electric testers at Amazon Resource: How to test and replace element How to test thermocouple Element tests for 120 volts How to test wire |
Safety
when testing wires: Never touch wet or previously flooded appliance. Never stand on wet surface when working on electric. Never stand on bare soil, put down dry boards. Tape tester leads to wood sticks to keep hands away from power. Use non-contact voltage tester before touching wires. Never touch or lean into any made of metal. Remove metal objects from pockets. Do not use oxygen or fuel accelerants in same room as electrical repairs Resource: Basic house wiring |

  When removing insulation from wire, do NOT score or put cuts on surface of copper wire. Doing so increases resistances on wire and creates weak point. Buy tools: Wire strippers at Amazon Linesman pliers Utility knife at Amazon End cutting nippers at Amazon |
 Use solid copper wire Fire inside timer caused by stranded wire Keep enclosure door closed at all times Buy: soldering guns Resource Timer caught fire |

Check that photo eye
rating matches voltage and wattage of Load. Each device has a volt and
amp rating located on the device. Some are rated 120-277, other rated
240 volt etc. 2) Blink on during day ... incorrect wiring 3) blink during night .... too much local light, turn photo eye away from light. Sodium bulb near end of life. Test by covering eye with black tape. 4) never turns off: low line voltage, wrong voltage rating, excessive load (you cannot use a photoeye to control 1 Hp motor for example) 5) never turns on: lamp burned out, voltage too high, wrong voltage, too much ambient light, device defective or burned out. 6) operates normally for a while and then remains on ,,, excess load (motor, too many bulbs) and contacts are fused. Replace photo eye. 7) fails to turn off, and appears burned ... lightning strike or surge might have burned out photoeye Check that power line is not running under or over voltage Check that wiring is correct using diagrams below With large loads such as several lights or motor etc, use photoeye to turn a contactor ON-OFF and let the contactor points handle heavy amp load.

120 Volt photocell wiring Photo eye control requires Neutral wire to power the internal switch. When exposed to light, the photo eye turns off internal switch, and cuts power between black hot wire and red wire to light. When darkness is sensed by photo eye, the switch is turned on and power flows to light through red wire. Neutral wire completes the circuit.

Face photo eye away from outdoor lights, to avoid blinking |

208-240 Volt photocell wiring 120Volt photo eye can control 240Volt load as long as Neutral wire is present. Photo eye control requires Neutral wire to power the internal switch. (Or for non-code-compliant solution, connect white wire on photocell to bare ground wire) 240Volt circuit can be turned off by turning off power to either Hot1 or Hot2. This is called turning off 'one leg' in 240V circuit. 12-3 wire or 10-3 wire is needed to provide 2 hot legs and 1 neutral Buy: Photo eyes at Amazon Resources: Read about 240Volt circuit |

How to wire photoeye so it turns
off 4 hours later 1-2-3-4-5-6-8 hours later Down to the minute, second, or hours Add delay timer to photoeye circuit Light turns on normally at dusk, then turns off after preset time expires. Set the delay timer to the exact minute, second or hour. Delay timer activates when photeye turns ON, and light turns on normally. When delay period expires, the light turns off, and timer resets to zero,. Timer and light remain OFF until photoeye activates the circuit again next night. Illustration shows twin timer.
