Megger This instrument is used to measure insulation resistance to ground. It consists of a crank- turned magneto, on the side of the case, and will give very close readings calibrated di- rectly in ohms. It is cranked at a moderate rate of speed, approximately 120 rpm, until the pointer reaches a steady deflection.

How to Use Volt-Ammeter CAUTION Power is ON during voltage checking. 1. Attach leads to volt-ammeter and select proper voltage scale for voltage to be tested. 2. Place leads in A position to test for presence of incoming voltage. • Voltage should be within + 10% of the design voltage specified on the motor nameplate in A, B and C test positions.
Page 75
WARNING! Power is ON during voltage checking. Using Amprobe 1. Set scale to highest amp range. 2. Connect amprobe around lead as shown. 3. Rotate scale to proper range and read value. 4. Compare value with table. What It Means – Currents above these values indicate system problems.
Page 76
CAUTION Power is ON during amperage testing.
Page 77
CAUTION Use ohmmeter only with POWER OFF. Power supply OFF. Disconnect motor leads (L1 and L2). On dual-voltage motors, motor must be wired 230V for the checks listed below and illustrated on the page indicated for each check. Rewire for 230V if necessary. CHECK: Page a.
Page 78
Ground Check CAUTION Disconnect Power Source before checking. a. Set ohmmeter to R x 1,000. b. Attach one probe to ground screw and touch other probe to all terminals on terminal board, switch, capacitor and protector – any ohmmeter reading indicates ground.
Page 79
Winding Continuity - A.O. Smith / Century Motor CAUTION Disconnect Power Source before checking. 1. Terminal board connected for 230 V. 2. Set ohmmeter to R x 1, adjust to 0. 3. Slip a heavy piece of paper between motor switch points, discharge the capacitor and take the following ohm readings: a.
Page 80
Ohmmeter tests on the new style terminal board with the quick-change voltage selector switch, see picture on pg. 76 (Black plastic part with 2 wires in it) is simplified if your ohmmeter is equipped with the sharp, pointed probes rather than alligator clips. With the voltage change plug on the 230 volt terminal the Black wire in the plug is positioned on Terminal “A”.
Page 81
Winding Continuity - US Motor CAUTION Disconnect Power Source before checking. 1. Terminal board connected for 230 V. 2. Set ohmmeter to R x 1, adjust to 0 (NOTE: Digital meters are typically used, the reading on this equipment should be showing OL or infinity). 3.
Page 82
Contact Points (Start Switch) CAUTION Disconnect Power Source before checking. 1. Set ohmmeter to R x 1, adjust to 0. 2. Remove leads from start switch. 3. Attach ohmmeter leads to each side of switch – reading should be 0. 4.
Page 83
Motor Overload Protector - US Motor CAUTION Disconnect Power Source before checking. 1. Set ohmmeter to R x 1, adjust to 0 (NOTE: Digital meters are typically used, the reading on this equipment should be showing OL or infinity) 2. Dissconnect the Overload protector leads 3.
Page 86
Capacitor CAUTION Disconnect Power Source before checking. IMPORTANT Discharge capacitor by touching the two terminals with the blade of an insulated handle screwdriver. 1. Set ohmmeter to R x 1,000, adjust to 0. 2. Disconnect leads on capacitor. 3. Attach ohmmeter leads to each terminal. Needle should swing to right and drift slowly to left.
Page 87
Adjust in proper Sequence: 1. CUT-IN: Turn range nut down for higher cut-in pressure, or up for lower cut-in. 2. CUT-OUT: Turn differential nut down for higher cut-out pressure, or up for lower cut-out. Note: Adjustment to range (cut-in) nut will also change cut-out pressure.

A vacuum gauge indicates total suction lift (vertical lift + friction loss = total lift) in inches of mercury. 1" on the gauge = 1.13 ft. of total suction lift (based on pump located at sea level). RULE OF THUMB Practical suction lift at sea level is 25 ft.
Page 89
Compound Vacuum Pressure Gauge This gauge will show the pressure or vacuum at any position in a pump or system where it is installed. A reading of 20" on a vacuum gauge placed on the suction side of the pump would tell you that you have a vacuum or suction lift of 22.6 ft.
Page 90
When pump is first started or under maximum flow condition, pressure control should be immediately adjusted to the pressure corresponding to H.P. and jet assembly used. See rating tables in catalog for proper pressure setting. 1. Turn left to reduce pressure. 2.

Correct rotation is a must on all 3Ø installations. Rotation can be checked by one of these three ways: Visual 1 1. Connect 3 motor leads to starter, run unit at open discharge. 2. Switch any 2 leads and again run unit at open discharge.

Calculate percentage of current unbalance for all three hookups. Example: Hook Up 1 Hook Up 2 Hook Up 3 T 1 = 51 Amps T 3 = 50 Amps T 2 = 50 Amps T 2 = 46 Amps T 1 = 48 Amps T 3 = 49 Amps T 3 = 53 Amps T 2 = 52 Amps...
Page 94
A full 3Ø supply is recommended for all 3Ø motors, consisting of three individual transformers or one 3Ø transformer. “Open” delta or wye con- nections using only two transformers can be used, but are more likely to cause problems from current unbalance.
