We recently updated our training and conference room, and added this Delta logo onto our white board cover.
A local Virginia facility engineer had an unusual, and mundane task to accomplish. In a newly completed housing building, the living quarters all are equipped with motion or occupancy sensor to increase the overall energy efficiency of the new building. With no motion in a particular room, the lights and HVAC systems are reduced or shut off. These particular occupancy sensors, illuminate utilizing a green LED when sensing motion. This however, in a darkened room is very bright and disturbed the occupants. The engineer found no published method to extinguish the LEDs, so he contacted the manufacturer. The manufacturer explained a procedure to accomplish this task. It was however a cumbersome task, especially when there were over 1100 of these sensors involved. The procedure goes something like this: Press the programming button 20 times, wait 1 second, press the button again 2 times, wait 1 second, press and hold the button 1 second, press the button 20 times. Can you imagine performing this procedure over 1100 times without a mistake?
Fortunately, he was already a user of the IDEC FT1A touch screen for other applications there. He designed and built the “jig” shown in this quick video, to program the occupancy sensors 5 at time, error free every time!
An efficient and fun project!

Prolonged Failure Of A VFD Gets Political Attention In South Central VA Town – Situation Abated by Delta Automation Engineers And Sales Team.
Delta Automation received an emergency call from water authority officials to repair a variable frequency drive (VFD) that controlled a very important monumental fountain that was erected in memory of a prominent local citizen. The operation and maintenance of the fountain is funded from a private grant. The problem of the fountain being down for so long became a sensitive political issue that was escalated all the way to the office of the Mayor.
The primary reason a VFD was utilized in this application is because the spray from the fountain could get misdirected due to moderate wind. The VFD and hence its pump motor, is piloted by wind speed (via an anemometer). The lower the wind speed, the greater the force of the fountain spray and water volume output. As the wind speed increased, the VFD would act to slow the pump speed down thus reducing the fountain’s force and volume of water spray.
Once Delta was contacted about the problem, our field service engineers, Lee Gleason and Kevin Randolph went to the site to investigate the problem, determined that the VFD was damaged beyond repair and that a new VFD was needed. Delta engineers specified and selected a replacement WEG CFW 11 VFD that was available with a low cost, quick shipment option. Once the price quotation furnished by the Delta sales specialist, Win Bradley, was approved by the municipality, the drive was ordered and installed the following business day and the fountain was returned to service. Both the Mayor’s office and maintenance officials were extremely pleased with the rapid response by Delta Automation on this project. The political ‘fire’ was extinguished once the fountain had been restored to service.
