Unison Paradigm® Light Sensor
Overview

The Unison Paradigm® Light Sensor provides light level measurement to the
connected Paradigm control system. The control system receives the measurements
to maintain a programmed lighting output in both dimmed and switched lighting
systems.

The Paradigm Light Sensors are available in three models:

• P-LS - Light Sensor with Controller

• P-LSC - Light Sensor Controller Only

• P-LSH - Light Sensor Only

Each controller supports an individual pair of Light Sensors and is available in neutral
white or black finish.

A light sensor may be installed within the controller or installed remotely, using up to
1,000 feet (304m) of 16 AWG wire per controller. When using a pair of light sensors,
both sensors transmit their light readings to a single controller which provides an
averaged reading to the connected Paradigm control system.

Wire Specification

Controller

The Paradigm Light Sensor utilizes LinkConnect to power the sensor and to provide
data to and from the connected Paradigm control system.

LinkConnect is topology-free and polarity independent. You can install your data runs
in any desired combination of bus, star, loop, and home-run. ETC recommends using
Belden 8471 (or equivalent) wire. The total combined length of a LinkConnect wire
run may not exceed 1,640 feet (500m), with a maximum distance of 1,312 feet (400m)
between any two devices.

ETC Installation Guide

Light Sensor

All control wiring should be installed and terminated by a qualified installer, should
follow standard wiring installation practices, and meet local codes. Leave
approximately 10 inches (254mm) of wiring in the junction box or tied back in the
ceiling to allow for wiring connections and future service needs.

Note:

ETC requires that all stations be grounded by using a 14 AWG (2.5mm2)
ESD drain wire.

Remoting the Light Sensor

The Paradigm Light Sensor Controller provides termination for up to two light
sensors. Each light sensor must be separately wired to the controller using no more
than 1000 feet (304m) of 16 AWG wire total per controller. These wire runs must
remain separate from LinkConnect wiring. ETC recommends using Belden 8471 (or
equivalent) wire.

Installation Environment

The Paradigm Light Sensor Controller is intended for installation to a finished ceiling
surface, soft ceiling tile, attached to a round fixture junction box or single-gang RACO
switch box. The controller operates in ambient temperatures of 0°C to 40°C, non­condensing humidity.

The Paradigm Light Sensor can be mounted directly in the controller, installed to a
1/2” conduit knockout or installed into a soft ceiling tile using the provided light
sensor thread extender. The light sensor can be installed outdoors when mounted to
a weatherproof enclosure. The sensor in this weatherproof installation scenario
operates in ambient temperatures of -25°C to 70°C.

Terminating Remote Light Sensor Control Wiring

Termination is available at the controller for up to two light sensors (labeled “Primary
Sensor” and “Optional Sensor”). When remote light sensors are installed, follow
these instructions to terminate the control wiring at both the light sensor and the
controller. Torque each termination to 3.1-3.5 in-lb.

Step 1:Terminate the incoming wire from the controller to the light sensor leads

using the WAGO cage clamp connectors (provided).

a: Strip 3/8” (9-10mm) from the ends of each wire (both light sensor lead and the

and wires from the controller).

b: Open the terminal levers on the WAGO connector and insert the installed

(typically black) Belden 8471 incoming wire and the black lead from the light
sensor.

c: Close the levers onto the wires.
d: Repeat for the installed (typically white) Belden 8471 wire and remaining wire

lead using another WAGO connector.

Step 2:Terminate the incoming wire pairs from the remote light sensors to the

controller.

a: At the controller, strip 3/16” (5mm) of insulation from the ends of each installed

light sensor wire.

b: Using a small 1/8” (3,35mm) flat blade or #1 Phillips screwdriver, loosen the

terminals on the ‘Primary Sensor” and ‘Secondary Sensor’ connectors found
on the underside of the controller.

c: Insert the black (typical) wire from the first light sensor wire pair into terminal ‘1’

of the ‘Primary Sensor’ connector.

d: Insert the white (typical) wire from the first light sensor wire pair into terminal ‘2’

of the ‘Primary Sensor’ connector.

e: Repeat this process for the second wire pair to the ‘Optional Sensor’ connector.

Power Up and Test

Power Up

For power to be applied to the Paradigm Light Sensor, any additional LinkConnect
terminations for the system must also be made. In addition, the Paradigm
Architectural Control Processor (P-ACP) and Station Power Module (P-SPM) must be
installed in the host DRd or ERn rack enclosure.

Identify Number of Connected Remote Sensors

The controller termination board includes an LED, labeled ‘Sensor Count’ that blinks
according to the number of remote sensors installed. 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 light sensors.

Unison Paradigm Light Sensor Installation Guide Page 7 of 8 Electronic Theatre Controls, Inc.

ETC Installation Guide

Light Sensor

Binding Sensors to Paradigm

The Paradigm Architectural Control Processor (P-ACP) to which this sensor is
physically wired to must learn, or be told, the station hardware address (known as a
neuron ID). When the sensor is unbound from the connected P-ACP, the service pin
LED blinks.

The neuron ID is labeled on the sensor control board and can be manually entered
into the configuration using LightDesigner software. Alternatively, the sensor can be
identified using the service pin button (designated with “S” on the button) and by the
connected Paradigm ACP using its [LonWorks Connections] menu. Reference the
related source documentation, either the LightDesigner Online Help System or the
Unison Paradigm Architectural Control Processor Configuration Manual; specifically
the section on Arch Setup Menu, LonWorks Connections.

Record a Target Lighting Value

The Paradigm Light Sensor includes a button that by default provides recording of
target lighting values for its dimming daylight harvesting feature. Pressing the record
button enables a five second timer and illuminates the LED red. When the timer
expires, the measured light level is stored as the amount of desired light that the
connected Paradigm control system should maintain, and the red LED blinks twice to
confirm.
