Frequently Asked Questions
1. I am thinking of installing a Variable Speed Pressure Limiting Controller, “VSPLC”. Are there special requirements for the motor(s)?
Yes. Motors for this type of controller are required to meet the applicable requirements of NEMA MG-1.Part 30 or 31. Also the motors shall be UL listed, suitable and marked for inverter duty.
2. In other fire pump applications, the motor service factor can be utilized. Can I use the motor service factor in this application?
No. The motor service factor cannot be used. Typically in fire pump applications motors have a service factor 1.15 and this factor can be utilized. In VSPLC applications the “service factor” is 1.0
3. Is the VSPLC available in various Nema enclosure types?
No. Due to cooling requirements VSPLCs are only available in Nema 12 enclosures.
4. Is there a bypass required for VSPLCs?
Yes, UL FM approved VSPLCs are required to have a bypass circuit in the event of VFD failure. This bypass can across the line, autotransformer or soft start bypass.
5. This controller and transfer switch is very large. I am not sure if I can get this in to my pump room in one piece. Can this unit be arranged to ship in multiple pieces?
Yes this is possible. Arrangements may be required to have a FTA representative or FTA Service Technician visit the site to inspect the reconnection of the various pieces once installed in the pump room. Contact your local FTA representative for specifics or the FTA factory.
