Digital Programmable Street Light Controller

Introduction

---

  JFT series digital street light controller adopts intelligent micro-processing chip, which can calculate the sunrise and sunset time through the latitude and longitude algorithm according to the operation law of the sun and the earth and the relationship between the latitude and longitude of the earth and the sunrise and sunset. It has the advantages of high reliability, small error, strong stability, and strong anti-interference ability, and can adapt to the needs of different geographic environments. JFT smart street light controller also has a built-in high-energy lithium battery (which can maintain the clock running for more than 10 years without changing the battery), which can effectively protect data in the event of a power failure. JFT intelligent street lamp controller has high-power relay output, which can be directly connected to 220VAC contactor or 380VAC contactor. JFT smart street lamp controllers are widely used in streets, railways, stations, waterways, industrial and mining, schools and power supply departments and other places.
  The JFT series street lamp controller can be divided into JFT-6 series and JFT-9 series. JFT-6 series street light controller is wall-mounted and has two output circuits (channel A and channel B). JFT-6 street light controllers have several working modes: full-night mode, half-night mode, and 2on-2off mode. According to whether it contains light control device, JFT-6 series can be divided into normal type and light-sense type. JFT-9 series street lamp controller is rail-mounted and has two output circuits (one normally open and one normally closed). JFT-9 series street light controllers have two working modes: full-night mode, and half-night mode.

OUTPUT 2: When the load 2 is connected to the Channel B, the output 2 LED will always be on.

Ⅱ Description of working modes

1 Automatic Mode
Channel A and Channel B can be set to three automatic working modes-full-night light mode, half-night light mode, 2on-2off light mode. Once set to automatic working mode, the load can be automatically switched on and off every day without human intervention.

Full-night working mode (turn on the lights in the evening and turn off the lights in the morning): According to the latitude and longitude information, the switching time of the street light is automatically controlled according to the seasonal change, that is, the street light is automatically turned on in the evening and the street light is automatically turned off in the morning. You can fine-tune the automatic switching time within ±120 minutes (negative means advance, positive means delay).

Half-night working mode (turn on the lights in the evening and turn off the lights in the middle of the night): According to the latitude and longitude information, the turn-on time of the street light is automatically controlled according to the seasonal change, that is, the street light is automatically turned on in the evening; the turn-off time needs to be set by yourself. You can fine-tune the auto-opening time in the range of ±120 minutes (negative means advance, positive means delay). The midnight light work mode can effectively save power than the all night light work mode.

2on-2off working mode (turn on the light in the evening and turn off the light in the middle of the night, and turn on the light in the early morning and turn off the light in the morning): On the basis of the half-night working mode, it will add a set of time to turn on the street light for a short time (which should be set by yourself) . This mode is often used to provide street lighting for cleaning staff working in the early morning.

2 Manual Mode
Long press the "MANU/ON" button for more than 2 seconds, JFT-6 will enter the "Manual Mode"(or "manual emergency light mode"), at this time JFT-6 will immediately turn on the street lights, and the display will show "MANUAL". In this mode, the switch states of A and B will not be controlled by the program. Long press the "MANU/ON" button for more than 2 seconds, JFT-6 will exit the "Manual Mode", at this time A and B will be automatically switched according to the set program, and the display will no longer display "MANUAL". Manual mode is often used for emergency lighting, equipment maintenance, major celebrations, etc.

3 Light Sensing Mode
If you need to turn on the street lights in advance in the evening of rainy days, you can choose the light-sense type JFT-6 (up to 30 minutes in advance). Compared with the normal type JFT-6, the light-sense type JFT-6 is equipped with a light sensor controller, which can turn on the lights in advance according to the change of natural light based on the latitude and longitude switching time. The light-sense type JFT-6 uses fuzzy mathematics to deal with changes in natural light, so it will not be affected by light fluctuations, artificial lighting, etc. during operation. Because light-sense type JFT-6 adopts automatic adjustment technology, it can effectively avoid the actual illuminance detection error caused by the different installation conditions of the photosensitive device and the drift of the device during long-term operation.
