1.Q. Inside my control panel there is a device with numerous small lights that turn on and off, what is it and how does it effect my systems operation ?
A. Many pump station are controlled by a PC or PLC (Programmable Controller or Programmable Logic Controller). It is usually a plastic enclosure with multiple LED’s (light emitting diodes), which represent inputs from various devices and outputs to other control devices.The inputs are interpreted by a program that is written by SyncroFlo engineers to allow the system to function automatically and normally under various conditions. If the PLC detects a hardware or software problem exists it will inhibit its own operation requiring manual operation of the pumps controls.
SyncroFlo retains copies of the PLC programs and any change requests must be processed through the engineering department.
2.Q. What type of maintenance is usually required inside my control panel?
A. The tightening of all wiring connections should be performed at start up and then once per year by a competent electrician or trained service technician. Additionally, contactors may require should be determined by a visual inspection performed during annual maintenance. Any service performed inside the control panel should only be done with power off and any remote disconnect locked out.
WARNING !! All circuits must be de-energized during servicing of the system. Dangerous voltages may be present on control systems connected to the pump system control panel.
3.Q. Can I connect other electrical components to the 120VAC power available in my SyncroFlo control panel ?
A. No, as the control power transformer and it’s protective fuses are rated to handle only the power demands of the control components themselves. Blown fuses may result if devices are connected that exceed the capacity of the transformer.
4.Q. Can I modify my control panel without adversely affecting the UL and ETL labels?
A. Generally, the anser is “no” as any modification that changes the wiring voids the UL label and therefore, also voids the ETL label.Components can be replaced with “like” components as needed to perform repair service as long as the wiring configuration is not modified.Contact the SyncroFlo Technical Support Department with specific inquires on this subject.
5.Q. Can I adjust the system pressure of my pump station? How do I do it?
A. Most pump station system pressure can be adjusted using the CRD (control regulating device), on the PRV (pressure regulating valve), piloting. Typically, a small flow of 20-25gpm must be established and maintained throughout the adjustment procedure. Some pumps and systems have more adjustability than others. Pay close attention to the pump curve and amperage draw. Systems provided with VFD’s (variable frequency drives) usually have their discharge pressure adjusted by entries to the OIT (operator interface terminal) call the factory for specifics of this procedure.
