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 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 up to two Light Sensor heads. One head may be
installed within the controller, or both may be installed remotely. When using
a pair of Light Sensor heads, each transmits their light readings to a single
controller. The controller averages the received light levels and uses the
average to control the lighting within the space.
Custom Configuration
This document guides you through the installation and local DIP switch setup
of the sensor. For more detailed information about custom configuration
options available using ElahoAccess, see the ElahoAccess App integrated help
system.
Note: To use the configuration settings applied using ElahoAccess,
DIP switch 2 must be enabled. See DIP Switch Settings on page9.

For use with Echoflex Elaho Control Systems, powered by an Elaho station
power supply.
Environment
Ambient
The controller ambient operating temperature range is 0to70°C
(32to158°F), with a non-condensing humidity. The Sensor head can be
installed remotely indoors or onto an outdoor weatherproof enclosure.
Ambient operating temperature range is -25to70°C(-13to158°F).
Wire Specification
The Light Sensor connects to the EchoConnect communication bus.
EchoConnect is a bi-directional protocol that uses one pair of wires (data+
and data-) for both data and power. Echoflex recommends using Belden
8471 Class 2 wire (or approved equal - see the Echoflex cable cross database
echoflexsolutions.com/files/Elaho_Data_Cable_Wire_Specs for equal
alternatives). The total combined length of an EchoConnect wire run using
Belden 8471 may not exceed 500m (1,640ft), with a maximum distance of
400m(1,312ft) between any two devices.
Note: All control wiring should be installed and terminated by a
qualified installer and should follow standard wiring installation
practices. Leave approximately 25.4cm (10in) of wiring in the back
box for connection and to allow slack for future service needs.
Note: Echoflex requires that all stations and devices be grounded for
ESDprotection. Pull an additional 2.5 mm2(14AWG) 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.
Light Sensor Head
The controller provides termination for up to two Sensor heads. Each head
must be separately wired to the controller using no more than 304m
(1,000ft) of 1.5mm2(16AWG ) wire total per controller. These wire runs
must remain separate from EchoConnect wiring. Echoflex recommends using
Belden 8471 (or equivalent) wire.

Sensor Configuration
The Light Sensor participates in an Elaho system
using the configured Space and Address, which you
set using the rotary switches on the Sensor
controller. DIP switches and the [MODE] button set
the Light Sensor functionality and the sensor
operation with dark and bright actions.
Basic
A sensor that is set for Basic configuration mode
(DIPswitch 2 set to Off) can be further configured locally using the other
available DIPswitch settings, and the [MODE] and Auxiliary [A] buttons and
their associated LEDs. See Configure Preset on page10 .

Light Sensor
Custom
For more detailed information about custom configuration options available
using ElahoAccess, see the ElahoAccess App integrated help system.
Set Space and Address
Two rotary switches on the sensor electronics provide for Space and Address
assignment for the sensor. By default, these switches are set to Space1,
Address1. Commands are shared by all devices within a given space.
1. Set the Space rotary switch to the desired number (1 through 16) for
the space you want the sensor to control.
2. Set the Address rotary switch to desired address (1 through 16) for the
sensor identification in the selected space.
Note: Do not duplicate a device Address within the same Space.
DIP Switch Settings
Use the DIP switches on the Light Sensor controller to locally configure the
sensor functions.
Switch # Use
1
Operation Mode - See Sensor Operation on page11 .
Off (default setting) = Dimmed operation (See Dimming Light Sensor
Operation on page12 .)
On = Switched operation (See Switched Photo Sensor Operation on page12 .)
2
Enable/Disable Custom Config Mode
When “Custom Config” is set to Off (also known as Basic configuration
mode), local DIP switch settings for the dark and bright actions are used.
Sensor actions can be adjusted using the program [MODE] button. This is the
default setting.
When “Custom Config” is set to On, all other local DIP switch settings are
ignored. Instead, the settings made by the ElahoAccess App are used.

Restore to Defaults at boot
When set to On and power is cycled to the sensor, the unit restores to its
factory default settings.
Off is the default setting.
Power Up
All EchoConnect terminations in the system must be made before applying
power to the system and sensor.
Sensor Count
The Sensor controller includes an LED labeled Mode/Sensor Count that blinks
green according to the number of Sensor heads connected to the controller.
Check this LED to ensure that the system has been wired properly and that
the controller has detected the number of connected sensor heads. If the
Mode/Sensor Count LED is solid red, the controller does not detect any
sensors. Check your system wiring first, and then contact Echoflex Technical
Services if additional troubleshooting assistance is required.
Configure Preset
When in Basic config mode (DIP switch 2 is
set to Off) and the sensor set to Switched
operation(DIPswitch 1 set to On), use the
[MODE] and Auxiliary [A] buttons to
configure the preset that is activated with a
dark action, meaning when the measured
light levels are below the target threshold
setting. The bright action is Off by default
and occurs when measured light levels are
above the target threshold. This is not
configurable through Program mode.

1. Access the Sensor controller and press and hold the [MODE] button
for three seconds to enter Program Mode. The Mode LED lights in
amber to indicate the sensor is in Program Mode and the Auxiliary[A]
button and LED on the front of the controller flashes to indicate the
preset number controlled by the dark action. By default, this is
Preset1, therefore the LED will flash one time, pause two seconds and
flash again.
2. Press the [A] button the desired number of times to set a new preset
for recall. The Auxiliary LED will blink to indicate the number of the
preset that will be used for the dark action.
3. Press and release the [MODE] button to save the current setting.
Attach Sensor
Attach the sensor to the mounting plate by aligning the tabs on the sensor
with the slots on the mounting plate, and then twist clockwise until the two
are locked into place.
Record Target
Auxiliary
Record
Target
The Record Target button, located on the front
of the Light Sensor snapshots the current light
(lux) settings in the installed space. This
snapshot determines the amount of light the
sensor should maintain.
When ready, press the Record Target button, a
10 second timer begins and a red LED
illuminates, indicating the record process.
•
Once the 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 Light 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.

Light Sensor
Dimming Light Sensor Operation
When the DIP switch 1 is set to Dimming operation, the Light Sensor executes
space raise and space lower commands until it measures the target amount of
light or until it reaches the extents of the artificial lighting control.
Press the “Record Target” button to record the amount of current light (lux)
the Light Sensor will try to maintain. It will raise or lower light levels 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.
Switched Photo Sensor Operation
When DIP switch 1 is set to Switched operation, the Light Sensor 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 Light 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 .
