Inquiry (采购产品): Model 438 Series Vibration Switch Dear Gentlemen, I work for a controls company that is trying to find information on the Model 438 series vibration switch for one of our customers. We are trying to reconnect this switch to a Air Handler Unit supply fans. we have a diagram on the back plate but do not know how to set this switch up properly. This vibration switch has never been connected into the control or AHU system. This is very dangerous do to the vane control fans pushing up to 400000 cfm. If you could send me information on this vibration switch I would be most thankful, or at least a place to find this information. Thank you for you time and concern. Thank you, Service Specialist Paul Howard Controls Innovations **** Hidden Message ***** Paul Howard TX 75002 USA Company: Controls Innovations Title: Service Specialist Phone: 972-965-0833 E-mail: pwhoward3@yahoo.com **** Hidden Message ***** pwhoward3@yahoo.com
