Use the pump H -O -A (Hand -Off -Automatic) switches in <br />Hand to test the pumps. If they operate well in Hand <br />proceed to test Automatic operation. If the pumps run <br />but fail to pump, they are probably air locked, drill the <br />relief holes per the instructions in the Piping Section. <br />Place Control Panel switch(es) in Automatic position <br />and thoroughly test the operation of the ON, OFF, and <br />Alarm floats by filling the wetwell with clear water. <br />Important: Failure to provide a Neutral from the power <br />supply to a 10, 230 volt Control Panel will not allow the <br />panel control circuit to operate. The Neutral is necessary <br />to complete the 115 volt control circuit. <br />Check voltage and amperage and record the data on the <br />front of this manual for future reference. Compare the <br />amperage readings to the pump nameplate maximum <br />amperage. If higher than nameplate amperage investigate <br />FLOAT SWITCH AND PANEL CHART <br />The purpose of this chart is to show the required switch <br />quantities and the function of each switch in a typical <br />wastewater system. The quantities required vary de- <br />pending on the switch type, single-action or wide-angle. <br />Switch quantities also vary by panel type: simplex with <br />and without alarms, and duplex with alarms. <br />Duplex Panels using single-action switches: <br />Three Float Panel Wiring <br />SW1 Bottom Pumps Off <br />SW2 Middle 1st Pump On <br />SW3 Top 2nd Pump & Alarm On <br />(--) Four Float Panel Wirin <br />SWl <br />Bottom <br />Pumps Off <br />SW2 <br />2nd <br />1st Pump On <br />SW3 <br />3rd <br />2nd Pump On <br />SW4 <br />Top <br />Alarm On <br />Duplex Panels using wide-angle switches: <br />Three Float Panel Wiring <br />SW1 Bottom 1st Pump On/Both Off <br />SW2 Top 2nd Pump & Alarm On <br />Four Float Panel Wiring <br />SW1 Bottom 1st Pump On/Both Off <br />SW2 Middle 2nd Pump On <br />SW3 Top Alarm On <br />Simplex Panel using single-action switches: <br />Simplex Panel with Alarmi0 <br />SW1 Bottom Pump Off <br />SW2 Middle Pump On <br />SW3 Top Alarm On/Off <br />Simplex Panel with No Alarm <br />SW1 Bottom Pump Off <br />SW2 Top Pump On <br />cause. Operating the pump off the curve, i.e. with too <br />little head or with high or low voltage will increase am- <br />perage. The motor will operate properly with voltage not <br />more than 10% above or below pump nameplate ratings. <br />Performance within this range will not necessarily be the <br />same as the published performance at the exact rated <br />nameplate frequency and voltage. Correct the problem <br />before proceeding. Three phase unbalance is also a pos- <br />sible cause. See Three Phase Power Unbalance and follow <br />the instructions. <br />Reset the Alarm circuit, place pump switch(es) in the <br />Automatic position and Control Switch in ON position. <br />The system is now ready for automatic operation. <br />Explain the operation of the pumps, controls and alarms <br />to the end user. Leave the paperwork with the owner or <br />at the control panel if in a dry, secure location. <br />Simplex Panel using wide-angle switches: <br />Simplex Panel with Alarm <br />SW1 Bottom Pump On/Off <br />SW2 Top Alarm On/Off <br />Simplex Panel with No Alarm <br />SW1 Pumn On/(off <br />Inlet <br />Alarm S' <br />Lag Pump Or <br />SW3 <br />Lead Pump Or <br />SW2 <br />Pump 0 <br />SW7 <br />Inlet <br />Alarm S1 <br />Pump On SW2 <br />Pump Off SV <br />Simplex O <br />Duplex O <br />rge <br />'ge <br />
