Automatic lighting system for steps of the ladder "SmartStairway SS-26"

The new model is a set of automatic LED backlight stairs allows you to connect up to 26 steps of stairs. Now you can use as a pyroelectric infrared sensors and ultrasonic rangefinders, in any combination, as you need.

Version 3.12.

Additions in this version:

- Added blocking of polling of pyroelectric sensors for powering up the system for 90 seconds. This allows you to avoid erroneous light on the stairs as a result of erroneous operations of the pyroelectric sensors during their heating during the first 90 seconds after turning on the power. Now you can use timers with the system, smart sockets compatible with Google House, Amazon Alexa and other systems requiring a complete power off of the system. Now the system will not cause false inclusions.

- Added the ability to dimming all steps in 10% increments in the range from 10% to 100% brightness. The brightness of the attendants (first and last steps), as before, is adjusted separately in the range from 0 to 100%

- Added system reset function to default settings. If you unconsciously changed the settings and do not know what and why you changed, you can return the system to the default settings.

The controller for an automatic lighting of stairways by means of low-power LED light sources. One controller is able to provide coverage of from 4 to 26 stages. The controllers have the ability to enable consistent, which allows to increase the possible number of steps almost to infinity. The system provides a flexible configuration for any customer requirements. The controller can be used in conjunction with a light sensor, or without it, with passage switches simple pyroelectric (infrared) and digital sensors to ensure smooth movement series circuit when the signal from the sensors in the direction of movement of people included on the ladder. The controller has a customizable interface and intuitive settings available. Easy to install.

The controller is made in a plastic case that can be mounted on DIN-rail or attached to the surface by means of screws or screws. (see photo)

The algorithm of the system

When the sensor has exposed the movement, the staircase lights are illuminated in the direction of the person's movement at the speed set in the system settings. After the waiting time has elapsed, the illumination of the steps set in the system settings is switched off in the reverse order. If during the illumination of the entire ladder the sensor detects motion, then the timer is reset to zero and the time until the light is turned off is considered from the moment when the sensor ceases to see the movement of people on the stairs.

If the movement on the stairs on the other side is detected while the backlight is on, the illumination is switched on in both directions. It also turns off in the reverse order.

If you press the "Down" or "Up" button, the backlight turns on from the pressed button and will be on until either of these buttons is pressed. The operation of the sensors is not taken into account. The "up" and "down" buttons on the controller are connected to the digital inputs of the controller "Up button" and "Down button". To these inputs you can connect additional buttons without fixing. For example, buttons for doorbells. See the diagram of the connection in the PDF file, the link to which you will find below. Additional buttons are not included.

Using a light sensor.

The controller can be used as a light sensor and without it. When connected to the controller light sensor should activate its use (claim 1. Setting) or deactivated when not using the sensor. The sensor should be installed in such a place that it would not be reached by light from indoor lighting and the lighting levels themselves. Digital sensor delivers a logic controller port 0 when the lighting is not sufficient or logical unit if the light level is less than the set limit. When the lighting is activated by light duty first and last stages and the controller is allowed to turn on the backlight levels for the signals from motion sensors depending on the selected algorithm (see. Above). When driving on the stairs when the backlight is switched on or suddenly steps onto the sensor light gets brighter light controller activation threshold - the staircase lights and duty levels off and the controller will go into standby mode. Job motion sensors and processing of people on the stairs counters maintained even when the lights on the signal light sensor is not implemented.

Using the motion sensor.

The controller allows you to connect any motion sensors, which you need. It can be both pyroelectric or ultrasonic. You can connect both sensors of the same type or a single pyroelectric and ultrasonic in any combination. The default factory setting for the width of the stairs of the ultrasonic sensor is set equal to 0.8 meter. The movement will be determined if the distance to the obstacle is reduced by more than 10 cm. Measurements of ultrasonic sensors are carried out by calculating the average value of 5 measurements, that virtually eliminates false positives when using ultrasonic sensors. If necessary, you can easily change the width of the stairs through the controller setup menu in step 7. Details can be found in the user manual URL: https://shop.xopc.net.ua/files/pasport_ss26_eng.pdf

Note! Ultrasonic sensors have certain technological shortcomings. Their principle of operation is based on the reflected high frequency sound. Therefore, ultrasonic sensors can not detect an obstacle if a person is dressed in a sound-absorbing clothes and have a certain delay in the work, because return time of the sound wave takes from 50 to 500 Milis

We recommend used pyroelectric sensors, whenever possible. The use of ultrasonic sensors is justified only when the staircase has no handrail or banister is delicate and next to the stairs is communicating zone through which people move and it may cause false triggering of illumination ladder pyroelectric sensors.To connect the ultrasonic sensor to use a shielded twisted pair wire with a cross section view of the length of the wire, but not less than 0.5 mm. square (AWG20). Braided shield is recommended to ground. It is recommended to avoid the length of more than 10m. If the wire is longer than 10m, should be applied thicker wire.

Ultrasonic sensors are not recommended to be installed at a distance of 50 cm from the floor or wall as this may cause false switching on the system.

The presence of other ultrasound sources in the sensor area may cause erroneous triggering.

Also note that ultrasonic rangefinders are capable of measuring distances of not more than 1.5 meters. If the distance to the reflective surface is very large or there is no such surface at all in front of the sensor, the sensor causes the backlight to be delayed for each stage for about 1 second. In such cases, you should try to pick up the installation site so that the sensor can see what kind of close-lying wall or obstacle or refuse this type of sensor.

Important.

Dear buyer. All products sent to you are tested on the stand for at least 72 hours. Also, before shipping the entire kit is tested for all functions and ports. After testing, the product is packed and shiping to you. After shiping, I provide you with a link to Youtube with a video report of checking and packaging your product (the video on YouTube is saved as confidential information and is only viewable to you). This allows you to completely exclude possible hidden defects, as well as disputes on health issues or product conformance. You can be sure that you get exactly what you see in the photo and video.

Please be very careful when connecting the product. First, mount the step lights and check the performance of each step separately by connecting them to the power source. Keep in mind that the power of the luminaires of one step does not exceed 0.4A (when the voltage of the luminaires is 12V - 5W, at a voltage of 24V - 10W). Exceeding the power of the fixtures or closing the wires of fixtures or LED strips will result in the failure of the output keys of the system. Check the polarity of the wires and sensors connected to the inputs carefully. Violation of the polarity or wrong connection of wires to the inputs can lead to the destruction of the microprocessor of the system and its failure. To the output + 5V only sensor power can be connected. The maximum load power to be connected to the "+ 5V" output must not exceed 500mA. Any damage to the product that may occur during improper connection or violation of the usage rules is not guaranteed and claims for them are not accepted.

If you have any questions about the connection, ask them to me. I will gladly answer your questions and help you. It is better to ask a question before the connection starts, as this will save a lot of time and effort, and also will save your ladder in good condition.

Note:

Starting from December 10, 2017, we changed the algorithm of the system and now the selection of pyroelectric or ultrasonic sensors is adjusted manually in step 7 of the settings menu. See how to do this from the link below:

Connecting LED strips or LED lighting fixtures.

First step.

First, mount the LED strip.

Connect all "+" clips to one lead to the "+" terminal of the power supply.

Then manually alternate and one-by-one connect the "-" wire from each step to the "-" terminal of the power supply. Make sure that all steps work correctly and there is no wire shortage. Also, make sure that there is no problem in the soldering points of the LED strips. If the tapes are mounted on a metal base, pay attention that the tapes do not close on the ground. Only convinced that everything is assembled and connected correctly and the power of one step does not exceed 0.4A (for a voltage of 12V nominally 4.8W, maximum permissible 5W.) Go to the second step

The second step.

- Disconnect the power supply from the mains.

Connect the test leads from the steps to the corresponding wires of the controller outputs. Note that the first step is connected to the "Out01" output, and the last step to the "Out26" output. The second step to "Out02", the third to "Out03" and so on. If you use fewer steps than 26, the last step is still connected to the "Out26" output.

After connecting all the steps and checking the correct connection of the wires and isolating them, you can turn on the power supply.

Note that shorting the wires "+" and "-" of the LED strip will result in exceeding the permissible power of one step and failure of the output on which there was a short circuit or even all groups of 7 steps of the chip on which there was a short circuit. Please be careful.

In this case, the first and last steps will be put on standby. By pressing the "Up" button "Down" you can check the LED strip lights. After that, turn off the power supply and connect the sensors according to the user's manual. Then turn on the system and adjust the number of steps you need. By default, the use of all 26 steps is enabled. If you use fewer steps and have not adjusted the number of steps used, then when you enter from the top of the step "Out26" to the next one, there will be a large delay in time during which the controller will include unused steps.

For ultrasonic sensors, the quality of the wires used is important. This should be a twisted pair of 0.5mm. square is necessarily shielded. Also, ultrasonic sensors may not work correctly when using sound-absorbing clothing or coatings. All features of ultrasonic sensors are described on the product page and in the user's manual.

Frequently Asked Questions

- Can I use a system with a 5V DC power supply?

The system is designed to operate with a supply voltage of 8 to 25V DC. Working with power supplies and luminaires with a voltage different

from the specified can cause damage or not stable operation of the system.

- What kind of lamps can I use?

The system is designed to be used in conjunction with LED lights or LED stripes with a voltage of 12 or 24 VDC.

The current of the luminaires or LED strips should not exceed 0.4A (0.5A maximum, taking into account the resistance of the wires at the point of connection to the controller) for one step.

Exceeding the current will lead to system failure. So for one step, the maximum power of luminaires with a supply voltage of 12V DC is 12V * 0.4A = 4.8W;

with a supply voltage of 24V DC 24V * 0.4A = 9.6W.

- I want to use LED stripes. What type and length can I connect to one step.

Data on the possibility of using different LED stripes, see the table:

!!! LED stripes on SMD2835 - Not recommended for use. (The reason is that SMD2835 LEDs have a power of 0.2, 0.5, 1W for a single LED. And you can never know which LEDs are used in the LED strip. You should not believe the parameters declared by the seller, since they are usually underestimated and are given for measurements on a cold LED strip in the first seconds for red LEDs. You can find out the real current strength for such LED strips only by measuring it yourself for at least 15 minutes, since the current strength of the LEDs increases as the LEDs heat up.)

- What kind of power supply should I choose?

The power supply should be selected based on the number of steps and the power of the luminaires of each step.

For example, you want to use 19 steps and install 4W lamps on each step:

19 steps * 4W = 76W. To the received capacity it is necessary to add 15% of the stock: 76W + 15% = 87.4W. You should choose a power supply with a power of at least 87.4W. The nearest larger of the available 90W or more.

The voltage of the power source should be the same as that of your luminaires (12 or 24 VDC).

- Can I use the system from the outside?

The system does not have water protection (IP20) and is designed for indoor operation.

The humidity in the controller or sensors "Smart Stairway" is not permissible.

You must ensure that it is protected against water when used outdoors. When using LED stripes from outside the room, you must reliably protect the system and the wiring from water ingress.

- I've connected everything, but I have some steps that shine less brightly than others and some do not turn on or off. What happened?

I can say with certainty that during the connection you made the closure of the wires of the LED strips or used LED stripes of too high power. This caused the failure of the controller output chips. Now they should be replaced. Also, sometimes the closure occurs when the LED strips come in contact with metal steps or aluminum profiles in which LED stripes are installed. To avoid this it is necessary to check the operation of each individual step before connecting to the controller. Also, the closure can occur when wet cleaning on the stairs and water on the LED strip without moisture protection. What can also cause a system closure and system outage. If you wash the ladder, please turn off the power to the system and turn it on again only after the staircase has dried completely.

- I've connected everything and everything works for me, but I have a big delay between switching on / off the last and the penultimate steps.

By default, the system is supplied configured to use 26 steps. If you use fewer steps, the system still spends time turning on and off unused steps. Therefore, you see a delay. You need to configure the system for the number of steps that you use. To do this, enter the menu item No. 2 and press the "Down" button until the penultimate step is turned off. Then click the "Up" button once. In this case, all your steps will be included. Press the SETUP button until the red LED is turned on continuously. Setup is complete.

- If I reduce the brightness of the stairs to less than 50%, when I turn on, I do not evenly turn on the light of the stairs. First, the LEDs begin to flicker in strobe mode and then turn on.

Starting with controller version 3.10, we have added the ability to dimming all LED strip strips. Dimming is possible from 10 to 100% brightness in increments of 10%. Then, when turned on, the brightness of each degree changes smoothly with 256 increments, changing the brightness from 0 to the maximum brightness you set. So if you set the maximum brightness for example 20%, then when the light is turned on, the system will turn on each step from 0 to 20% using 256 increments, while in one increments the brightness will change by 0.078%. During which time this happens very little and is set by you as the speed of inclusion of all the steps in paragraph 4 of the menu. Usually it is no more than 0.5 seconds for one step. As you know, not all LED strips can correctly display such a small dimming step and ensure a smooth visual effect. Inexpensive LED strips, especially based on SMD5050, SMD5730 (5630), SMD3010 LEDs, have ballast resistors in their design that cannot handle such a low dimming step with these LEDs. Therefore, visually it looks like several steps of inclusion (flashes). In this case, you should not set a low brightness in item 6 of the settings menu and use its value less than 50% or use high-quality LED strips based on SMD3528 CREE or Epistar chips.

- Can I turn on the system so that all the steps are turned on until I turn them off?

Yes, there is such an opportunity. When you press the Up button or the Down button, the steps are turned in the direction of the pressed button and will be turned on until you press either of the two buttons again. Also you can connect a button without a latch (buttons for a door bell for example) to the inputs "Up button" and "Down button". In this case, one wire from the button should be connected to the output "+ 5V", and the second wire to the input "Up button" or "Button down".
