QUESTIONS FOR CONTRACTOR OR INSTALLER
- Were sensor and power cable tied or strapped to discharge line?
- On what kind of spacing?
- What is the as-built length of riser and sump? Were cables long enough? There should be 3 or more feet of slack in the cables.
- What size cable was run for supply power?
- What is the distance from power supply transformer to pump control panel?
- How did they verify that pump is down into sump?
- Did they test level sensor prior to installing?
- Did they test pump prior to installing or prior to your arrival?
- Do they have any questions or concerns?
- Complete Form 200.
PHYSICAL INSPECTION OF CONTROL PANEL
- Is the control panel located 15' from sump or riser and 36" above grade to bottom of panel?
- Are power and sensor cable run in separate conduit? If not, stop work and have this corrected?
- Are seal offs installed in both sensor and power runs? If not, suggest breakout junction boxes or have seal off installed?
- Are seal offs potted? If not, stop work and have them potted.
- Will inner and outer door of enclosure open and close freely? If not, loosen enclosure mounting bolts and shim until it is level and square. Then retighten mounting bolts.
- Make sure ground wire is in place between outer door and enclosure.
PRIOR TO ENERGIZING CONTROL PANEL
- Measure resistance to ground. It must be less than 25 ohms. If greater, stop work and report to owner. It should be 1 ohm or less to protect electronic equipment.
- Measure voltage prior to control panel or at entrances to control panel. Measure and record voltage line to line and line to ground.
- Compare these readings to voltage listed on drawing and label in control panel.
- Megger motor leads resistance must be 1 megohm or greater.
- Take ohm reading of each motor lead wire to wire and compare these to values in Table 13 of the Franklin Electric motor manual for 1Ø and Table 21 for 3Ø. Be sure to add wire resistance value to value from Table 13 & 21. See page 39 in the Franklin manual for wire resistance.
- Inspect inside of control panel. Look for items which may have come loose during shipping.
- Inspect wire connections. Are they the correct colors? Are they tight?
- If color-coded wires were not continued from sump or riser, you need to ohm out each circuit.
- Review equipment list and drawings from any accessory circuits. If present, run volt and ohm test.
- Check and make sure all hand switches are in off position. If you have a water level indicator, verify leachate level in sump or riser.
- Turn on power at panel main disconnect.
- Level meter display should light up. Record displayed reading. How does this reading compare to your measured level reading?
- If level and flow meter do not light up, check GFCI, reset if necessary.
- Are any indicator lights on?
- Should they be on?
- Make sure pump is turned off. Using built in or hand held simulator, verify level meter settings are correct for this site.
- Bump pump by turning hand switch two or three times to make sure pump has reached its resting point. You should have minimum of 3' of slack in the cables.
- To verify correct rotation, place hand around discharge line. It will torque right if the rotation is correct.
- If there is liquid in sump with level above pump start set point and below 150", then turn pump selector switch to AUTO. Run pump through one complete cycle.
- When pump is running, measure and record amperage and voltage. Check 3Ø systems for current balance within 5% of average.
- Verify that starting, running and stopping causes no significant vibration or hydraulic shocks.
