13 Paul W. Donoho, R.E.H.S. #6227 (530) 701-9972 AdvanTeXe O&M COMMERCIAL TREATMENT SYSTEMS Inspection Points Inspection Points-Control Panels 3.Conduit seal Installation:check for conduit seals on all conduit connections to the control panel. Panel •n. WARNING:Failing to seal the conduit may allow corrosive gasses to corrode major components oienco recommends conduit seals for all connections to the control panel to assure piopersystem e operation and component longevity. 4.Power supply voltage:Make sure the panel breakers are switched ` off,and check the power supply voltage at the panel. Not • On 120 V panels,measure voltage between a and ground.The voltage should be within ten percent of nominal. _ • On 230 V panels,measure the voltage between L1 and ground, and between L2 and ground.The voltage of each leg should be JJer r approximately 115 volts.Measure the voltage between L1 and 112. The voltage should be within ten percent of nominal. The system may have multiple control panels.Identify if there are control . On 208 V,230 V,and 460 V 3-phase panels,measure the voltage panels on the section of the system that you are about to start-up. between L1&L2,L2&L3,and L3&Lt.The voltage between If the tank or basin has associated controls,perform the following start-up each leg should be 208,230 or 460 volts,respectively.ti there steps: is a voltage difference between line legs,it is an Indication that the power source may be undersized.The voltage between each 1.Panel documentation:Locate the panel-wiring diagram inside leg and ground on 208 volts should be approximately 120 volts. the panel and verify the document matches the document number The voltage between each leg and ground on 460 volts should be found on the inside of the front panel door.If you can't find the wiring approximately 277 volts.(Due to the variability in the ways 230 V, diagram,contact Orenco at(800)348-9843 or(541)459-4449 to 3-phase power can be wired,there is not a standard test method.) have a copy e-mailed or faxed to you. 5.Neutral and ground voltage:Check for any voltage difference 2.Wiring installation. between each neutral(N)wire in the panel and ground.If there is Verify all of the main a difference in voltage,use the wiring diagram to track down the breakers are in the source of the difference and correct it. "OFF"position.inspect 6.Controls circuit Connect the controls circuit if it is not already the wire terminatons connected.The controls circuit is now ready to be turned on.Do not in the panel by giving turn on the pump circuit at this time. a light tug to all of the WARNING:7uming the pump circuit on at this time can damage the float wires,pump wires, pomp power lines,and panel or the pump if the pumps and floats are miswired or if there isn't sufficient liquid in the tank main power lines in the . panel.If a wire comes loose,reattach the wire correctly. WARNING:Failure to idsnfi y a loose wire may muse intermittent fallures,inconsistent panel operation and over- curient conditions on the pumps.
