Introduction

Motor and Phase Rotation Indicator is a handheld,

battery-operated instrument designed to detect

the rotary field of three-phase systems and

determine motor-rotation direction.

Protection provided by the instrument will be

impaired if used in a manner not specified by the

manufacturer.

Motor and Phase Rotation Indicator ships with the

following items:

• 3 test probes

• 3 alligator clips

• 9 V battery

• Users Manual

If an item is damaged or missing, contact the place

of purchase immediately.

Accessories

Safety Information

• Read the following safety information carefully

before using or servicing the instrument.

• Adhere to local and national safety codes.

• Individual protective equipment must be used to

prevent shock and injury

• Use of instrument in a manner not specified by

the manufacturer may impair safety

features/protection provided by the equipment.

• Avoid working alone.

• Inspect the test leads for damaged insulation or

exposed metal. Check test lead continuity.

Damage leads must be replaced. Do not use the

apparatus if it looks damaged.

identifies conditions and actions that may

damage the apparatus.

CAUTION

identifies conditions and actions that pose

hazard(s) to the user.

WARNING

Safety Information To avoid possible

electric shock or fire, do the following:

Read First

03 04

Symbols

• Be careful when working above 30 V ac rms, 42 V

ac peak and 60 V dc. Such voltages pose a shock

hazard.

• When using the probes, keep fingers away from

probe contacts. Keep fingers behind the finger

guards on the probes.

• Measurements can be adversely affected by

impedances of additional operating circuits

connected in parallel or by transient currents.

• Verify operation on a known source prior to

measuring hazardous voltages (voltages above

30 V ac rms, 42 V ac peak and 60 V dc).

• Do not use the apparatus with any of the parts

removed.

• Do not use the apparatus around explosive gas,

vapor, or dust.

• Disconnect the test leads from power sources and

the apparatus before changing the battery.

• Do not use the apparatus in a wet environment.

The following symbols appear on the Motor and

Phase Rotation Indicator or in this manual.

WARNING

if the neutral conductor, N, is connected instead

of L1, L2, or L3. Refer to Figure 2 (also shown on

the face of the apparatus) for more information.

Figure 2. Phase Indication Table (shown on the

face of the apparatus)

Non-Contact Rotary Field Indication

For non-contact rotary field indication:

1. Disconnect all test probes or alligator clips from the

apparatus.

2. Position the Indicator on the motor so that it is

parallel to the length of the motor shaft. The

Indicator should be one inch or closer to the motor.

See Figure 3.

The rotary indicator lights

Note

The Indicator will not operate with engines

controlled by frequency converters. The bottom of

the apparatus should be oriented towards the drive

shaft. See the Orientation Symbol on the apparatus.

Figure 3. Motor Rotation

See Table 2 for the minimum motor diameter and

number of pole pair to obtain a reliable test result.

3. Press the ON/OFF button. The green ON indicator

shows that the instrument is ready for testing.

Either the Clockwise or Counter Clockwise Rotary

indicator illuminates showing the type of rotary

field direction present.

Table 2. Reliable Motor Test Requirements

Determine the Motor Connection

1. Connect the alligator clips to the other end of

the test leads.

2. Connect the alligator clips to the motor

connections, L1 to U, L2 to V, L3 to W.

3. Press the ON/OFF button. The green ON indicator

shows that the instrument is ready for testing.

4. Turn the motor shaft half a revolution towards

the right.

Note

The bottom of the apparatus should be oriented

towards the drive shaft . See the Orientation

Symbol on the apparatus.

Either the Clockwise or Counter Clockwise Rotary

indicator illuminates showing the type of rotary

field direction present.

Magnetic Field Detection

To detect a magnetic field, place the apparatus to

a solenoid valve. A magnetic field is present if

either the Clockwise or the Counter Clockwise

Rotary indicator illuminate.

Maintaining The Apparatus

This section provides basic maintenance

information.

To avoid damaging the apparatus:

• Do not attempt to repair or service the

apparatus unless qualified to do so.

• Make sure that the relevant calibration,

performance test, and service information

is being used.

Caution

Cleaning

Periodically wipe the case with a damp cloth and

mild detergent. Clean only with soap and water and

remove any residue afterwards.

Caution

To avoid damaging the apparatus:

• Do not use abrasives or solvents. Abrasives

or solvents will damage the apparatus case.

• Prior to cleaning, remove test leads from the

apparatus.

Replacing And Disposing Of The Batteries

Warning

To avoid electric shock, disconnect the test

leads from the source before opening the

apparatus for battery replacement.

Note

The apparatus contains alkaline batteries. Do not

dispose of these batteries with other solid waste.

Used batteries should be disposed of by a qualified

recycler or hazardous materials handler.

13 14

The apparatus uses a 9 V battery (supplied).

To replace the battery, follow these steps and refer

to Figure 4:

1. Disconnect test leads from any power source.

2. Place the apparatus face down on a nonabrasive

surface and loosen the battery-door screw with

a screwdriver.

3. Lift the battery access lid away from the apparatus.

4. Replace the battery as shown in Figure 4.

Observe the battery polarity shown in the battery

compartment.

5. Secure the battery access lid back in position

with the screw.

6. Place the apparatus back in the holster.
