Overview
The Elaho Light Sensor provides light level measurement and lighting control
for the connected Elaho control system. The sensor measures lighting
conditions to maintain a programmed lighting output in both dimmed and
switched systems.
Light Sensor Head with Controller
Light Sensor Head
Thread Extender
Light Sensors are available in three models:
•
E-LS - Light Sensor head with controller
•
E-LSC - Light Sensor controller only
•
E-LSH - Light Sensor head only
Each controller supports one or two Light Sensor heads and is available in
white or black finish. A Light Sensor head may be installed remotely or within
the controller, using up to 1,000 feet (304 m) of 16 AWG (1.5 mm2) wire per
controller. When using a pair of Light Sensor heads, both sensor heads
transmit their light readings to a single Light Sensor controller. The controller
averages the levels and uses them to control lighting within the space.
Custom Configuration
This document guides you through the installation and local configuration of
the Elaho Light Sensor. For more detailed information about the custom
configuration options available for the Light Sensor using ElahoAccess,
reference the ElahoAccess Mobile App integrated help system.
Note: To use the configuration settings applied using ElahoAccess, DIP
switch 2 must be enabled. Reference DIP Switch Settings on page 8.

Echoflex Installation Guide
Elaho Light Sensor
Wire Specification
Controller
The Light Sensor controller utilizes EchoConnect for power and for data
communications with an Elaho control system.
EchoConnect is a bidirectional protocol that uses one pair of wires (data+ and
data-) for both data and power. Echoflex recommends using Belden 8471 (or
approved equal) Class 2 wire.
The total combined length of an EchoConnect wire run (using Belden 8471, or
equal) may not exceed 1,640feet (500m).
Note: All control wiring should be installed and terminated by a
qualified installer and should follow standard wiring installation practices.
Leave approximately 8" (20cm) of wiring in the back box for connection
and to allow slack for future service needs.
Note: Echoflex requires that all Elaho stations and devices be grounded
for ESDprotection. Pull an additional 14AWG (2.5 mm2) wire for
grounding when control wires are not installed in grounded metal conduit.
Note: When using Category 5 (or equivalent) cable on the EchoConnect
communication bus, please note the following:
•
Cat5 wiring must be terminated using EchoConnect Cat5
Termination Kit and must be installed using a bus topology.
Refer to the installation guide that is provided with the Cat5
Termination Kit (8186A1207) for information to terminate
Cat5 wiring.
•
Not all topologies are supported using Cat5; careful planning
is required to ensure the proper termination kits are available
and the wire is pulled appropriately.
Remoting the Light Sensor Head
The Light Sensor controller provides termination for up to two remote Light
Sensor heads. Each Light Sensor head must be separately wired to the
controller using no more than 1,000 feet (304 m) of 16 AWG (1.5 mm2) wire
total per controller. These wire runs must remain separate from EchoConnect
wiring. Echoflex recommends using Belden 8471 (or equivalent) wire.

Sensor Configuration
The Elaho Light Sensor participates in an Elaho system using the configured
Space and Address, which are selectable using the rotary switches on the rear
panel of the sensor.
Additional DIP switches and the [Mode] button, also located on the rear panel,
set the sensor functionality and the sensor function with dark and bright
actions.
Set Space and Address
Two rotary switches on the rear panel
of the controller provide for
assignment of the sensor Space and
Address. By default, these switches are
set to Space 1, Address 1.
Do not duplicate a device Address
within the same Space.
Commands are shared by all devices
within a space.
DIP Switch Settings
DIP switches on the rear panel of the
Light Sensor controller provide for additional configuration options including
deadband sensitivity, delay time, and the ability to restore the sensor to its
factory defaults.
DIP Switch 1
DIP switch position 1 determines whether the sensor will use a Dimming
operation (Off) or a Switched operation (On). The default setting is Dimming
operation. Reference Sensor Operation on page11.
Elaho Light Sensor Page 8 of 12 Echoflex Solutions, Inc.

Echoflex Installation Guide
Elaho Light Sensor
DIP Switch 2
DIP switch 2 enables “Custom Config” which instructs the sensor to use
settings that are configured using the ElahoAccess Mobile App. This setting is
“Off” by default.
•
When “Custom Config” is set to “Off”, the default position, local DIP
switch settings for the “Dark” and “Bright” actions are used. Sensor
actions can be adjusted using the program [MODE] button.
•
When “Custom Config” is set to “On” the local DIP switch settings
are ignored. Instead, the Delay Time, Deadband Sensitivity, Switched
or Dimming operation setting, Dark or Bright event settings, and
Dimming Raise and Lower Event settings made in the ElahoAccess
Mobile App will be used.
DIP Switch 3&4
DIP switches 3 & 4 set the “Delay Time”. Supported times are in minutes.
•
5 min = Switches 3 and 4 are “Off” (default)
•
15 min = Switches 3 is “Off” and 4 is “On”
•
30 min = Switches 3 is “On” and 4 is “Off”
•
60 min = Switches 3 and 4 are “On”
DIP Switch 5&6
DIP switches 5 & 6 set the deadband sensitivity, which corresponds to 10%,
20%, 35%, and 50% as a percentage of the Target Lux. The low measured
light threshold is Target - (Target x Deadband%) / 100. See Record Target
on page11. The high measured light threshold is Target + (Target x
Deadband%) / 100.
•
10% = Switches 5 and 6 are “Off”
•
20% = Switch 5 is “Off” and 6 is “On”
•
35% = Switch 5 is “On” and 6 is “Off”
•
50% = Switches 5 and 6 are “On”
DIP Switch 7
DIP switch 7 is not used in this product.
DIP Switch 8
DIP switch 8 provides a “restore defaults at boot” function. The factory
defaults are restored by setting this DIP switch “On” and cycling power to the
sensor.
Power Up and Final Installation
Power Up
All EchoConnect terminations in the system must be made before applying
power to the system and sensor.

Elaho Light Sensor
Sensor Count
The controller includes an LED, labeled “Mode/Sensor Count” that blinks
green according to the number of remote Light Sensor heads connected to the
controller. As needed, refer to this LED to ensure the system has been wired
properly and the controller has properly detected the correct number of
connected remote heads. If the Mode/Sensor Count LED is solid red, the
controller does not detect any sensors. Check your system wiring first, then
contact Echoflex Technical Services if additional troubleshooting assistance is
required. A maximum of two heads are allowed per controller.
Configure Preset
Mode button
Mode/Sensor Count LED
When in Basic config
mode (DIP switch 2 is
set to Off), holding the
[Mode] button sets the
sensor into program
mode. Program mode
only affects switched
operation and is used
to adjust the preset
controlled by the
“Dark” action when
measured light levels
are below the target
threshold setting. The
“Bright” action is “Off,” and occurs when measured light levels are above the
target threshold. This is not configurable through Program mode.
1. Press and hold the [MODE] button for 3 seconds. The Mode/Sensor
Count LED will turn solid amber and the “A” (Auxiliary) button on the
front of the Light Sensor controller will begin to blink the number of
times that corresponds to the preset number used for the “Dark”
action.
2. Press the “A” button the desired number of times to set a new preset
for recall. The “A” button LED will blink to indicate the number of the
preset that will be used for the “Dark” action.
3. Press the [MODE] button to save the current setting.The Mode/Sensor
Count LED will turn off and the “A” button LED will blink to indicate
the saved preset value.
Attach Sensor
Attach the sensor to the mounting plate by aligning the tabs on the sensor
with the slots on the mounting plate, then twist clockwise until the two are
locked into place.

Record Target
Auxiliary
button
Record
target
button
The “Record Target” button takes a snapshot
of the current light (lux) settings, which
determines the amount of light the sensor
should maintain.
1. Push the “Record Target” button. A
10 second timer begins and a green
LED illuminates, indicating the record
process.
•
Once the 10 second timer finishes,
the current measured lux value
records as the target (threshold)
value.
•
The LED will blink twice when the target (threshold) value is
successfully recorded.
•
Pressing “Record Target” again during the 10 second timer will
cancel the record process.
Sensor Operation
Dimming and Switched Photo Sensor operation settings only apply in Basic
config mode (DIP switch 2 is set to Off). When in Custom config mode (DIP
switch 2 is set to On) settings applied from ElahoAccess are used instead.
Dimming Photo Sensor Operation
When the DIP switch 1 is set to Dimming operation, the sensor executes
space raise and space lower commands until the sensor measures the target
amount of light, or until it reaches the extents of the artificial lighting control.
The “Record Target” button records the amount of light (lux) the sensor will
try to maintain. The sensor raises or lowers light after the measured light is
respectively above or below the target thresholds for the configured delay
time (calculated as target +/- the amount of percent deadband sensitivity)
until the target amount of light is achieved or it reaches the extents of the
raise/lower commands.
Example: Assume the recorded target has been set to 1500 lux, and deadband
sensitivity is set to 20%. When measurements drop below 1200 lux, the
sensor will attempt to raise lighting. When measurements rise above 1800
lux, the sensor will attempt to lower lighting.
•
The low measured light threshold is
Target - (Target x Deadband%) / 100.
•
The high measured light threshold is
Target + (Target x Deadband%) / 100.
•
To ensure a smooth transition, the Dimming operation does not
exceed a fade rate greater than one second per percent dimmed.
Elaho Light Sensor Page 11 of 12 Echoflex Solutions, Inc.

Echoflex Installation Guide
Elaho Light Sensor
Switched Photo Sensor Operation
When DIP switch 1 is set to Switched operation, the sensor by default
performs threshold based activation of both a “Dark” and a “Bright”
condition, which are determined by the lux threshold settings. Lighting actions
occur after measurements have been maintained for the configured delay
time.
•
By default, the “Dark” action activates Preset 1 in the device’s space,
and the “Bright” action executes the space “Off” command.
•
When used in a space with manual wall station controls, the “Dark”
action cannot be allowed anytime the space is in the “Off” state. Also
when used in the same space with Occupancy/Vacancy sensors, the
“Dark” action is only allowed when there is occupancy.
•
Even in Automatic-On operation (no Inspire or preset station manual
controls were detected), the sensor is prohibited from turning on lights
after the space off command has been given by another device.
However, if the sensor itself issues the “Off” command (due to bright
conditions), it will turn on lighting if conditions become too dark.
