Halcyon Silent Broken Animation Sensor
Issue
Halcyon Silent Animation Rotate sensor (labeled "FLAR") can break after transportation. Please contact HES/ETC Service to get more information.
Explanation of Issue
The animation sensor could break due to a collision with the screw on the head cover. The screw makes contact with the white multi-pin connector at the back of the sensor. After repeated vibration or impact to the head cover the connector soldier joints wear down and eventually break off. It is not a very common occurrence as these fixture are primarily in fixed installations, but this could be an issue if units are transported.
Serial numbers 727025090001-0100 will have a connector located at the front preventing the issue from occurring.
Parts Needed:
- Replacement Sensor Part Number: 2591A4035
- Small zip style cable ties
Tools Needed:
- #2 Philips head screwdriver
- Cable tie cutters/snips
Solution
- Remove the head covers and pull out the effects module. There are two screws on either side and a total of three connectors. 2x power and 1x Data (red)

- Next, remove the metal plate holding the PCBs and sensor. There are 4 screws on the backside which hold the standoffs to the metalwork.

- Remove the sensor (yellow circled) and cut the three cable ties (red circled) to increase usable cable length. The original sensor might be labeled "FLAR"


- Replace the failed sensor with a new sensor using the original two screws. Sensor Part Number 2591A4035 *The sensor connector terminal goes toward the inside of the unit when installed*

- Reroute the cable to connect with the sensor. You can replace the cable ties to organize any excess cable.

- Reinstall effects module into the fixture.
- On the fixture display menu under Settings - Service PIN 4116, clear any errors that may have been logged in previous power cycles. Test fixture functionality prior to putting on the head covers.
