Gen 4 Sensor Firmware v5.5.0

Firmware release version 5.5.0 supports all Generation 4 sensors and supersedes all previous 5.x firmware releases. These release notes cover the new features and bug fixes for release versions since the 5.1.34 release. Any devices running 5.1.x or 5.3.x should be updated to version 5.5.0.

Audience

The purpose of this document is to provide detailed release notes for the 5.5.0 firmware release for Enlighted’s Gen 4 sensors. This document is intended for Enlighted’s internal Field Engineering and Sales Engineering teams as well as partners.

Features

This section outlines the features implemented between the 5.1.34 release and this release. Specific feature detail is based on the release version where it first appears.

5.5.0 Release

• Default Profile – Un-commissioned sensors no longer have a constant 65% output setting. SU-5E sensors will have a 65% default output but will dim to 20% if motion is not seen for 19 minutes. SU-5S sensors have 100% default output and will dim to 20% if motion is not seen for 19 minutes.
• Discovery Strobe – Un-commissioned sensors will transmit a discovery response when strobed by a green laser. No longer is a message from the Energy Manager or EMConfig required to initiate the discovery response, however, either method will work.
• Improved Laser Strobing – improves sensitivity to the green laser strobe. The sensor’s ambient light detector has been calibrated to detect strobing from 1mW GREEN laser pointers.  Note that as a result of this modification strobing the sensor with a bright flashlight no longer works.

5.3.6 Release

• Wiring Test Two-Minute Hold Bypass – The sensor will continue to hold the dimming level at 100% for two minutes at the end of the wiring test, but the sensor will exit this mode if it receives a valid message from the Energy Manager or Room Control (ERC).

Bug Fixes and Workarounds

Fixes in version 5.5.0:

• The PIR motion detection algorithm has been modified to reduce the number of false motion events.
• Fixed issues that were causing sensors in daylight harvesting groups to cycle slowly at undesirable light levels when communication with the Energy Manager is interrupted or fails.
• Improved robustness of the sensor during special states of operation.
  • Added check to prevent the processing of any commands before the wiring test completes
  • Reduced potential for issues caused by inadvertent interference among sensors in a range of multiple field people doing commissioning operations.
  • Added checks on which commands to accept or ignore based on the connection status.
• Sensor no longer forces occupancy sensitivity to 1 when in a dark room which would interfere with desired occupancy sensitivity.
• The sensor now correctly reports the time since the sensor detected local motion to the Energy Manager. Previous firmware versions reported the time since the motion for the group (for motion grouped sensors).
• The sensor ignores duplicate discovery requests to improve discovery success rate when a large number of sensors.
• Fixed issue that was causing the LED state to be temporarily incorrect when commissioned sensor which is in hopper mode is temporarily moved to the default channel during discovery or commissioning.
• Protection added against inadvertent commands from the EM that enable or disable the hopper setting of a commissioned sensor while there is an active discovery process. This prevents the sensor from accidentally being put in a decommissioned state during the discovery process when it is temporarily assigned as a hopper on the default communications channel.

Fixes in version 5.3.7

• The sensor now checks to ensure that it never reports negative energy or power value to the Energy Manager.
• The motion sensitivity filter algorithm was modified to fix an issue that was causing the sensor to stop responding to motion when motion is detected around the time when a tick timer is rolling over.

Fixes in Version 5.3.6

• Fixed a problem with Plug Load Controller falling into safety mode when the motion group is vacant.
• Fixed incorrect sensor behavior in response to ERC OFF button press. Sometimes the light would go to linger dim level for one second before going OFF.
• Fixed bad daylight harvesting behavior that caused lights to bounce back and forth between min and off when "Allow daylight harvesting to dim lights below the minimum light level." The checkbox in the Energy Manager is checked.
• Corrected the ManualOn switch group behavior when pressing the ERC AUTO button. Now both ManualOn and AutoOn switch groups behave the same way when pressing the ERC AUTO button, as follows:
  • When lights in the room are OFF, pressing the AUTO button is same as pressing the ON button. This is safety behavior.
  • When lights in the room are ON, pressing the AUTO button cancels any override, and returns to Auto mode, which typically changes the light level back to follow the profile.
• Modified switch group override behavior to behave independently of motion group behavior. The impact of this change is:
  • Remote motion signaled by a member of a motion group does not impact the duration of the in-progress switch group override.
  • Pressing ERC ON or SCENE button will change light level and start the switch group override time interval.
  • Any in-progress switch group override (from the ERC) may be extended indefinitely by continuous motion detection by the sensors of the switch group.
• Fixed a problem when daylight harvesting brings down the light level and unexpectedly light comes back to Task tune level.
• Group motion events now trigger multiple messages to be sent in order to improve sensors in Motion or Switch groups synchronizing their state with each other.
• Fixed a problem that caused lights to turn on at the beginning of a new period even though the EM Advanced checkbox for "At a time period change when there is no motion, allow a change in minimum light level to raise the light levels" was unchecked.
• Hoppers being used to hop ERC communications to the GW will now properly communicate the ERC low battery status as well.

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 at the transition between dim and off, the SU 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.

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 configuration data structure.
