Gen 4 Sensor Firmware v5.6.2

For Partners & Customers.

Read the release notes and download the Gen 4 Sensor firmware v5.6.2 firmware image from the link at the bottom of the article. Upload the image file to the system and schedule either an automatic or manual image upgrade. 

Introduction

Firmware release version 5.6.2 supports all Gen 4 sensors and supersedes all previous 5.x firmware releases. These release notes cover the new features and enhancements for release versions since the 5.5 release.

Caution

The maximum number of 2-Wire drivers connected to a sensor is limited to five, by design. This firmware release and future firmware releases will not change this limitation.

5.6.2 New Features

The 5.6.2 firmware release provides the following new features:

1. Smart Ramp – Supports the Energy Manager (V3.9.12 or later) Advanced Profile Max Override option “When motion is detected, ramp up to target ambient light level over 3 seconds to improve energy savings.”
2. Enhanced Daylight Harvest – This version of the firmware improves the Daylight Harvest algorithm.

Enhancements and Fixes

This firmware release provides the following enhancements and fixes

1. Incorrect Driver Count – The firmware fixes occasional incorrect driver count after power loss.
2. Room Temperature Corrected – The firmware fixes occasional incorrect temperature readings after reaching high-temperature levels.
3. ERC Auto button – The ERC Auto button action will now be consistent across all sensor states.  The Auto button will always cause the sensor to return to Automatic lighting control, which will determine the light level in the room. Removed unwanted behavior of switching lights ON when lights OFF. 

Limitations and Known Issues

The following limitations for this release should be noted:

• Ramp up time in lighting profiles is also applied to ramp downtime for switch OFF events.
• When a fixture dims to a linger light level on vacancy, the ramp-up time is used when motion signals the light to ramp back up.
• When motion repeatedly prompts the fixture to go back to maximum after a dim and linger event, the period’s motion timeout is used instead of the maximum timeout of all periods in the profile.  
• When there is a small difference (e.g., 20% difference) between the current light level and the minimum or maximum light level, long-pressing the ERC to dim down/up occurs very quickly such that the light level jumps to the min/max instead of dimming one step down/up.
• Fixtures that are in daylight groups with ambient sensitivity equal to 10, in switch groups set to manual on, have a minimum profile value greater than zero, and have a profile where the advanced option allows for daylight harvesting below the min may cycle between off and the minimum light level.
• The analog (0-10V) dimming interfaces on the sensor implement a linear dimming curve, which maps 0-100% dimming intensity to a 0-10V dimming voltage.  To ensure correct operation when transitioning between dim and off, the sensor must be paired with either a Control Unit or a 0-10V driver capable of supporting a dim-to-off threshold of 0.8V. +/- 0.1V (driver shut off below 0.7V, turn on above 0.9V). This is not an issue for digital dimming ESI drivers or DALI drivers.

Sensor LED Status Summary

The table below summarizes the sensor status based on the LED behavior.

Supported Sensors 

This release supports the following sensors:

• SU-4E
• SU-4S-H
• SU-4S-LRW/LRB
• SU-4S-HRW/HRB
• SU-4S-LBW
• FS-D22
• CS-D2

Supported Upgrade Paths

This release supports the SU-4E/SU-4S sensor firmware upgrades directly from firmware versions 3.4.0, 3.6.6, 5.1.32, 5.3.6, and 5.5.  FS-D22/CS-D2 sensor firmware upgrades from versions 3.4.0, 3.6.6, 3.8.0, 5.1.32, 5.3.6 and 5.5 are supported.

For other sensor firmware versions, contact  Enlighted Customer Support for additional information.

An updated Compatibility List for this release supports automatic upgrades with the Energy Manager to this version. 

Note that once sensors have been updated to 5.x versions, downgrades to 3.x version are not possible due to changes in the structure of the configuration data.

Firmware Compatibility

The table below provides the supported releases, including the recommended device firmware versions to be used with this release.

Primary testing of this release was done with EM 3.9.12 and GW 2.8.36.  It is recommended that the customer be updated to these versions if possible.
