echoflex TAP-31 Photo and CCT Sensors Installation Guide

echoflex TAP-31 Photo and CCT Sensors

Overview

The Photo Sensor (TAP-31) and CCT & Photo Sensor (TAP-41) are wireless solar- powered sensors that provide a reliable and simple method for increasing energy savings by adding daylight harvesting capability to an Echoflex lighting control system.
The TAP-31 supports two equipment profile settings that measure ambient light intensity in two ranges: 0–1,020 lux (0–95 fc) and 0–65,535 lux (0–6,090 fc).
The TAP-41 combines correlated color temperature (CCT) and light intensity monitoring to match fixture output with outdoor values or predefined color temperature values. The sensor supports four equipment profile settings that monitor exterior light levels up to 100,000 lux (9,290 fc) and a color temperature range of 2,000–7,500 kelvin to maximize the lighting adjustment for a tunable white LED fixture throughout the day. This document covers installation, testing, and settings that apply to all TAP-31 and TAP-41 models. The product package includes the sensor and two wire staples.

Prepare for Installation

To ensure optimal function, consider the installation environment and the following guidelines:

• For indoor use only. Operating temperature -25°C to 65°C (-13°F to 149°F), 5%–92% relative humidity (non-condensing).
• High density construction materials and large metal appliances or fixtures in the space may disrupt wireless transmissions.
• Install the sensor within range of linked receivers or controllers, 24 m (80 ft) unobstructed view. Consider adding a repeater to extend the wireless signal, if required.
• Before linking the sensor, expose it to a good light source for at least five minutes at 200 lux (19 fc).

Supplies required to install (not provided):

• Two #6 screws, double-sided tape, or Velcro®

Installation

The sensor should be installed in a location where it has direct exposure to a window or skylight. For example, mount the sensor on the ceiling, aligned with a window about 1.2 m (4 ft) away.
The sensor can be attached to most surfaces; suspended ceiling tile, finished wallboard, or other surfaces using a flexible adhesive.
Note: A concrete or metal mounting surface can limit radio communication. Create some separation by mounting the sensor first on non-metalic material, e.g., 1/2-inch plywood.
The location and position of the sensor directly affects the quality of messages received by the linked controller. Determine the installation method and follow the instructions.
Note: Consider linking the TAP-31 TAP-41 while you have access and before replacing the cover. See Link to a Controller on the facing page.

Wire Staples to Ceiling Tile

1. Use your fingers to remove the sensor’s cover, flexing it gently to release the tabs that hold it in place. If you have difficulty, try inserting a small flatblade screwdriver under one of the release tabs.
2. Mark the sensor mounting location on the ceiling tile.
3. Remove the ceiling tile from the T-bar frame.
4. Insert the wire staples (provided) through the pinholes on the sensor, one set located on each side near the keyholes.
5. Poke the tines through the ceiling tile, then bend each tine over in opposite directions for a secure fit.
6. Replace the ceiling tile and reattach the sensor cover.

Wallboard Ceiling

1. Use your fingers to remove the sensor’s cover, flexing it gently to release the tabs that hold it in place. If you have difficulty, try inserting a small flatblade screwdriver under one of the release tabs.
2. Mark the location of the keyholes on the ceiling.
3. Bore two holes and insert screw anchors (not provided).
4. Attach the sensor to the ceiling with screws (not provided).
5. Replace the sensor cover.

Integrated Magnets

Attach the sensor directly to the suspended ceiling T-bar frame using the two integrated magnets.

Adhesive
Use double-sided tape or Velcro (not provided). Cut a piece of double-sided adhesive tape or adhesive-backed Velcro to the appropriate length and press firmly in place.

Link to a Controller

The compatible target controller must be installed, powered, and within range of the TAP-31 TAP-41.
Note: The linking process can be used both to link a device to a controller and to unlink a linked device from a controller.

1. Use your fingers to remove the sensor’s flexible cover and access the [Teach] button. If you have difficulty, consider inserting a small flatblade screwdriver under one of the release tabs.
2. Press the [Learn] button on the controller to activate Link mode. If necessary, refer to the controller product documentation.
3. Press the [Teach] button on the sensor once to send a link message. An LED blinks to confirm a successful transmission.
4. Deactivate Link mode on the controller before attempting to link to any other controllers.

Battery Power

A CR1632 battery is not required for normal operation if the sensor receives adequate natural or artificial light. See the table in the Light Level Test on page 5. A battery (not provided) may be required to run installation tests or when the artificial light is insufficient to power the sensor.

To install the battery:

1. Use your fingers to remove the sensor’s cover, flexing it gently to release the tabs that hold it in place. If you have difficulty, try inserting a small flatblade screwdriver under one of the release tabs.
2. Insert a new battery in the holder with the + positive side facing up and press in place.
3. Replace the sensor cover.

Sensor Operation

The sensor records sample values at a rate based on the current ambient light level and the stored energy in the sensor. The sensor is configured to transmit messages at a heartbeat rate and immediately when daylight levels change more than 12%. During normal operation, the heartbeat rate is 10 times longer than the sample rate.
The table below shows the range of ambient light values that determine the sample rate compared to the heartbeat rate. The sample rate marks the recording of daylight level values used to calculate the percent of change, while the heartbeat rate marks the transmission of a message.

Ambient Light Value Lux (Footcandles)| Sample Rate| Heartbeat Message Rate
---|---|---
< 10 (< 1)| 128 seconds| > 21 minutes
< 50 (< 4.6)| 64 seconds| 10 minutes
< 100 (< 9.3)| 32 seconds| 320 seconds

100 (> 9.3)| 16 seconds| 160 seconds

For the sensor to send an on-change message, it needs sufficient power:

• Stored energy above 3.5 V, or
• Ambient light level above 300 lux (27.9 fc), or
• An installed battery

On-Change Formula

The sensor compares the current sample value to an average of the last three readings. If the difference is more than 12%, the sensor transmits the value immediately.
The averaged reading ensures that the sensor sends multiple messages if a large change occurs before it returns to sending messages at the default heartbeat transmission rate.
If both the average lux value and the current lux value are less than 50 lux, the on-change transmission behavior is disabled.
Note: On-change behavior for the TAP-41’s CCT value is determined in a similar way as the lux level. If a large step change occurs, the CCT in kelvin can be smoothed out using a calculated average reading.

Tests and Settings

Use the [Teach] button and color LEDs to navigate the Tests and Settings menu. Remove the cover to access the [Teach] button located beside the battery clip. The LEDs display through the front lens.
Note: A battery is required to run tests or change settings. If you cannot access the LED blink menu, install a good battery. See Battery Power on page 3 for installation instructions.

• Light Level Test (green LED)
• Range Confirmation (blue LED)
• Rapid Response Test (red LED)

The menu times out after two minutes of inactivity.

Light Level Test

The Light Level Test quantifies the amount of energy produced by the solar cells and confirms a good installation location.

1. Press and hold the [Teach] button until the green LED is displayed. Release the button to enter the menu and display the first item, the blinking green LED.
2. Press and hold the [Teach] button again until the green LED stops blinking. The green LED then repeats a number of blinks according to the detected light level. The sensor reevaluates the light level every two seconds.

Blinks| Ambient Light Lux (Footcandles)| Time to Fully Charge| To Maintain Charge
---|---|---|---
0| < 40 (< 3.7)| Non-operational| N/A
1| 40–100 (3.7–9.3)| Operational| N/A
2| 100–200 (9.3–18.6)| 30–60 hours| 8 hours per day
3| 200–400 (18.6–37.2)| 15–30 hours| 4 hours per day
4| 400–1000 (37.2–92.9)| 7–15 hours| 2 hours per day
5| > 1000 (> 92.9)| 3–7 hours| 1 hour per day

The test repeats every two seconds and runs for 100 seconds. To exit before the time-out, press and hold the [Teach] button for 10 seconds.

Range Confirmation

The Range Confirmation test quantifies the strength of the wireless signal to a linked controller that has range confirmation capability.
Note: Only one controller can be linked to the TAP-31 TAP-41 to run the test properly. Disable repeaters that are in range.

1. Press and hold the [Teach] button until the green LED is displayed. Release the button to enter the menu and display the first item, the blinking green LED.
2. Press and release the [Teach] button to cycle through the menu of color LEDs and stop when the blue LED is blinking.
3. Press and hold the [Teach] button until the LED stops blinking to initiate the Range Confirmation test.
   After the TAP-31 TAP-41 transmits and receives a Range Confirmation message, the signal strength status is displayed as an LED blink color.

The test repeats every five seconds and runs for 50 seconds. To exit before the time-out, press and hold the [Teach] button.

Rapid Response Test

The Rapid Response Test confirms the settings on powered controllers to which the TAP-31 TAP-41 is linked. The test accelerates the sensor’s message rate, making the controller respond to light level changes faster. The transmission rate is increased to every 16 seconds for 100 seconds and then returns to normal operation.

1. Press and hold the [Teach] button until the green LED is displayed. Release the button to enter the menu and display the first item, the blinking green LED.
2. Press and release the [Teach] button to cycle through the menu of color LEDs and stop when the red LED is blinking.
