Power Up and Final Installation
Power Up
All EchoConnect terminations in the system must be made before applying
power to the system and 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 Light Sensor Heads. If the Mode/Sensor Count LED is solid red, the
controller does not detect any sensors. Check your system wiring first, then
contact ETC Technical Services if additional troubleshooting assistance is
required. A maximum of two Light Sensor Heads are allowed per controller.
Configure Preset
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.
Step 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 number of Preset used for the “Dark”
action.
Step 2: Press the “A” button the number of times to set a new Preset. The “A”
button LED will blink out the number of the Preset that will be used for
the “Dark” action.
Step 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 out the saved
Preset value.
