6. breaker and control fuse for tripping or for blown condition b Check incoming power voltage and control circuit voltage c Check overload relay to see if it is tripped Reset relay if tripped d With the power off check motor heat sensor continuity e Check wiring of pump to control panel It should agree with the schematic f Check contactor coil resistance It should be 125 to 150 ohms 2 Pump does not run in Auto position a Check items a through d per Item 1 b Floats may be miswired to control panel Check float type N O or N C and hook up by referring to the schematic If the start and stop floats are hooked in reverse pump will short cycle and will not pump the level down c Is the water level in the system high enough to activate floats dl With the power off remove off float and on float wires and replace with two jumpers made from insulated wire d2 Turn power on with H O A switch in Auto position If pump runs the problem is in one of the floats d3 If the problem is in a float Turn power off remove jumper and reconnect the upper float Turn power on and see if pump will run in Auto This will help identify which float is the problem Turn power off before removing any jumper or reconnecting any float 3 Pump runs but run light does not energize a Run light is neon Remove light and check on outside 120V source Panel Troublesh
7. checks 7 Motor winding resistance readings a Disconnect all three motor leads b Using a volt ohm meter with the scale set on RX1 measure the resistance between the leads with chart figure A Chart Figure A Typical Motor Resistance Winding Leads Reading Main Black to Lowest White Start Black to Next Red Lowest Middle Both White to Highest Red 8 Capacitor Check a Make sure the capacitors are discharged Use extreme caution severe shock hazard may exist with capacitors b Disconnect the capacitor leads and connect a volt ohm meter to the capacitor terminals The meter should indicate low ohms when it is first connected but as the capacitor becomes charged by the meter it will return to a reading of infinity open circuit NOTE Set the meter on the RX10 000 scale to check the run capacitor Set the meter on the RX1 000 scale to check the start capacitor 9 Start relay check a Check the coil resistance It should be 5500 to 6000 ohms Install a clamp on amp meter around the start winding lead Set the amp meter scale to at least 2 times the pump motor full load current Place the H O A switch in the Hand position to start the pump The meter should read approximately 2 times full load current during starting After the motor has started within one second the current should drop to full load current or less 10
8. e 4 and CSA weatherproof conduit hubs when connecting to this enclosure Prior to conducting any installation repair or service with regard to the control panel refer to the schematic appropriate for that panel The schematic will provide guidance with regard to the terminal block connections CAUTION Nonmetallic enclosure does not provide grounding conduit connections Use grounding bushing and Jumper wires Make the following Electrical Connections a Connect the pump leads to the control panel When connecting the pump leads it is very critical that the proper sequence be maintained On single phase pumps the color coded pump leads black white red must be connected to the appropriate terminals as directed by the control schematic b Connect all the float control leads to the appropriate panel terminal blocks Contractor must be very careful in locating the floats at the proper elevations c Before connecting power to the control panel make sure all control switches e g H O A switch and protective devices e g breakers are in the off position Now connect power to the circuit breaker as directed by the schematic d Power must be the correct voltage for the pump model Power must have neutral to supply 120 volts to control circuit e Control panel must be grounded properly per NEC and or local codes To facilitate this a ground lug is provided on the control panel Start up
9. ooting b Check for loose wire at light or in panel 4 Pump runs but does not pump down the wet well a Impeller may be dragging in volute due to solids High amperage draw would identify this b Refer to the pump manual for other possibilities such as closed discharge gate valve etc 5 Severe humming chattering of contactors and control relays a There may be low voltage Check voltage to the panel and to the control circuit using a voltmeter This low voltage condition may even cause severe chattering and burn out of relays Contactors require a minimum of 85 of full voltage to pull in without chatter If the problem is a recurring one measure voltage with recorder ona 24 hour basis b Contactor may have dust around magnet of coil structure Dry or clean as required c Make sure the floats are located away from any turbulence d Dry out the junction box if furnished moisture in the junction box may tend to cause relays to energize intermittently 6 Nuisance tripping of overload on the motor starters or the circuit breakers a Check all reset buttons and tripped breakers b Check pump and draw with amp probe and compare to nameplate amps on pump c The impeller may be locked up due to excessive debris or solids d Possible motor failure fault on windings e Pump may be miswired to terminal block WARNING Disconnect all power from the panel before making these
10. p The maintenance schedule will vary with operating and environmental conditions It will also vary with the specific type of control supplied The list herein is a guide only 1 Exercise breaker through two cycles Be careful not to over exercise as the breaker is not a switching device Excessive operations tend to affect the trip curve of the breaker 2 Check run light operation by running pump in Hand 3 Check continuity control fuse through 4 Check voltage to the panel and to the control circuit 5 Check the pump full load amps Troubleshooting 6 Check the start relay by using an amp probe around the red wire start winding Amp probe should display a very brisk action from zero to locked rotor and back to operating load This action occurs on pump start and the action must show no lazy movement 7 Check enclosure for moisture Moisture may cause chattering of relays and contactors 8 Check control capsule gasket for proper seal This can be a visual inspection 9 Check labels to verify they have not been damaged 10 Pull floats and check for proper operation and ensure there is no foreign buildup on them Panel WARNING Before handling these pumps and controls always disconnect the power first Do not smoke or use sparkable electrical devices or flames in a septic gaseous or possible septic sump 1 Pump does not run in Hand position a Check pump circuit
