Controls and Indicators

1. PWR Breaker: This is a combination 25A circuit
breaker and a POWER ON switch.

2. CAP100/200/300: Selects one of the three starting
capacitor ranges.

Position Range

100MFD 88-180MFD
200MFD 161-193MFD
300MFD 249-301MFD

3. REV/OFF/FWD: Switch determines the mode of
operation of the compressor. In the FWD position,
power is applied to the compressor motor run
winding, and the start capacitor is connected to the
START cable. In the REV position, power is applied

Hermetic Compressor Analyzer

to the compressor motor start winding and the start
capacitor is connected to the RUN cable. In the OFF
position, the power circuit to the motor is broken.

The REV position is momentary. The OFF and FWD
positions are sustained.

4. FAULT/CONT./START: Is a multi-function switch.
The FAULT (momentary action) position is used
to check for shorts between the COM and the RUN/
START windings. The CONT. (sustained action) posi­tion is used to check for GROUND, RUN and START
continuity. In the START (momentary action) position,

the start capacitor is connected to the

compressor motor through the REV/OFF/FWD switch.

5. Ground Test (Yellow): This push button switch

tests for ground continuity between system ground
and the frame of the appliance being tested.

The HA1 introduces an “artificial ground” to make
possible the testing for short circuits between the
motor winding and the frame of appliances which

may not be directly grounded. For example, units

with two wire power cords would not be connected

to system ground (unless a separate ground
connection were present).

6. Start Test (Red): This push button switch test two

conditions, depending on the position of the FAULT/
CONT./START switch.

Switch Position Condition Tested

FAULT Short between START winding

and frame

CONT. Continuity of START winding

7. Run Test (Black): This push button switch tests

two conditions, depending on the position of the

FAULT/CON./START switch.

Switch Position Condition Tested

FAULT Short between RUN winding

and frame

CONT. Continuity of RUN winding

8. Indicator Light: LINE NORM (white)/REV (red).
These lights are used to indicate the “condition” of
the power source to which the HA1 is connected.

Line Voltage Indicator Light Status

110 V AC NORM on/REV off Normal

REV on/NORM off Neutral and line wires

reversed at power

receptacle. Refer to

CAUTION under section on

110 V AC operation

NORM and REV System ground open or not

on (half intensity) connected at power receptacle

220 V AC NORM and REV Normal

on (full intensity)

9. Test Jacks: The four test jacks are connected
directly to the test cable of the corresponding
color:

COMMON = white
GROUND* = yellow
START = red
RUN = black

The purpose of the test jacks is to facilitate

resistance and voltage readings by enabling

voltmeter/ohm meter test leads to be

connected to the compressor motor circuit

by inserting them into the appropriate jack

at the HA1 front panel.

*Since this cable is an “artificial” ground line it is colored
yellow instead of green.

Operating Instructions

NOTE: Every effort has been made to make the
HA1 a safe and versatile tester. However, under
some circumstances line voltage may be present on
the HA1 test cables when the control switches are in
the OFF position. For this reason it is very important
to read and become familiar with the section on
Operating Instructions.

The following procedures have been detailed so a
thorough understanding of the operation sequence

may be gained. In practice, the following tests may

be performed very quickly.

110 V AC Operation

CAUTION!

The HA1 is wired so that the white COMMON test
cable is connected to the neutral side of the line.
The red START and black RUN cables are connected
to the hot side of the line by the POWER BREAKER
switch and the REV/OFF/FWD switch. If the 110 V AC
receptacle has been accidentally reverse wired, the
white COMMON cable will be “hot” as soon as the
HA1 is plugged into the power receptacle. To warn
against such a condition, the red REV LINE indica­tor will light as soon as the HA1 is plugged into a
grounded receptacle. In this case follow procedure B
for reversed line condition.

A. Normal Test Procedure

1. The REV/OFF/FWD switch must be in the

OFF position.

2. Plug the HA1 into a grounded 110 V AC

receptacle and turn on the POWER switch.

This is a push on - push off switch. The white

NORM LINE indicator should light.

NOTE: If the receptacle is ungrounded, both the
NORM and the REV LINE indicator will light, but at
half intensity. The absence of a grounded line will
not prevent any of the following tests from being
made. IMPORTANT: verify that the receptacle is
not also reverse wired by measuring the voltage
between the white COM cable and a ground
connection. A reversed line will measure 110 V AC.
A normal line will measure zero volts. If the
receptacle is reverse wired, follow procedure B.

3. Remove power to the unit which is to be tested.

4. Remove and identify the connectors going to

the common, start, and run terminals of the
compressor motor.

5. Connect the test cables of the HA1 to the

compressor motor.

• Yellow GROUND cable to compressor

motor frame

• Red START cable to the start terminal

• Black RUN cable to the run terminal

• Leave the white COMMON cable

disconnected until step 7

6. Push the FAULT/CONT./START switch to the
FAULT position and hold it there while press-
ing the red START TEST and black RUN TEST

switches in turn. If either the START indica-
tor or RUN indicator lights, there is a short

between that winding and the frame. STOP the

test and replace the unit.

7. Connect the white COMMON cable to the

common terminal of the compressor motor.

8. Press, in turn, the GROUND TEST, START
TEST, and RUN TEST switches. The

appropriate indicator will light indicating
continuity in the circuit being tested.

NOTE: To test for ground continuity the
appliance must be plugged into a grounded
110 V AC receptacle or be grounded through
an external connection.

If either the run or start winding indicate open,

stop the test and replace the unit.

9. Select the appropriate motor start capacitor.

10. Press the FAULT/CONT./START switch to the
START position and, holding it there, throw
the REV/OFF/FWD switch to the FWD posi-

tion. If the compressor starts, release the

START switch. The compressor will continue
to run. The compressor may be stopped by
returning the REV/OFF/FWD switch to the
OFF position.

If the compressor does not start immediately,

the rotor may be locked. Release the START
switch and return the REV/OFF/FWD switch to
the OFF position.

11. To “bump” the compressor, press the
FAULT/CONT./START switch to the START
position and, holding it there, throw the REV/
OFF/FWD switch to the REV position. If
the compressor starts immediately, then

release both switches. Repeat step 10 to

assure that the compressor will run in the
forwards direction.

If the compressor does not start immediately

in reverse, then release both switches. A locked
rotor will result in excessive current being
drawn by the compressor.

12. Steps 10 & 11 may be repeated a few times in

an attempt to free a locked rotor, but care
should be taken not to overheat the motor

windings. If the compressor still does not start,

then it should be replaced.

13. Push the POWER BREAKER switch OFF.
Disconnect the HA1 test cables from the motor.

B. Reversed Line Operation

If the 110 V AC receptacle is reverse wired the main
thing to remember is that the white COMMON cable

will be “hot” regardless of any HA1 switch setting.
Therefore, exercise extreme care.

Follow the same procedure as for Normal Operation
(A) steps 1 through 6, but keep the white COMMON

cable isolated to prevent accidental contact with it.

Before doing step 7, unplug the HA1 from the power

receptacle, connect the white COMMON cable to the

common terminal of the motor, and then plug the HA1
into the power receptacle.

Proceed with the tests outlines in steps 8 through 12,

section A.

220 V AC Operation

CAUTION!

The white COM cable will be hot as soon as the HA1 line
cord is connected to 220 V AC. Always make sure that
power to the HA1 is shut off before connecting the HA1
cables to the compressor motor on 220 V AC operation.

1. The REV/OFF/FWD switch and the PWR
BREAKER switch must be in the off position.

2. Remove power to the unit which is to be tested.

3. Some compressor units have fans mounted in

the same housing as the compressor. If possible turn

down the thermostat, or disconnect the fan, so that
the fan will not operate during the compressor tests.
The fan noise could make it difficult to listen to the
action of the compressor.

4. Remove and identify the connectors going to

the COMMON, START, and RUN terminals of the
compressor motor.

5. Connect the test cables of the HA1 to the

compressor motor.

• Yellow GROUND cable to compressor

motor frame

• Red START cable to the start terminal

• Black RUN cable to the run terminal

• Leave the white COMMON cable
disconnected until step 10

6. Use an adapter cord of at least #14 AWG wire size

to connect the HA1 to the 220 V AC input terminals.

7. Turn on the power to the HA1.

NOTE: Remember to keep the white COM cable out
of the way. It will have 110 V AC on the clip.

8. Push the POWER BREAKER to the ON position.

Both LINE NORM/REV indicators will light.

9. Push the FAULT/CONT./START switch to the

FAULT position and hold it there while pressing the
red START TEST and black RUN TEST switches in

sequence. If either the START indicator or RUN
indicator lights, there is a short between that winding
and the frame. STOP the test and replace the unit.

10. Turn off the 220 V AC power source to the HA1.

Connect the white COM cable to the common

terminal of the compressor motor.

11. Press, in turn, the GROUND, TEST, START TEST,

and RUN TEST switches. The appropriate indicator
will light indicating continuity in the circuit being

tested. If either the run or start winding indicate

open, stop the test and replace the unit.

12. Select the appropriate motor start capacitor.

13. Press the FAULT/CONT./START switch to the

START position and, holding it there, throw the
REV/OFF/FWD switch to the FWD position. If the

compressor starts, release the START switch. The
compressor will continue to run. The compressor
may be stopped by returning the REV/OFF/FWD
switch to the OFF position.

If the compressor does not start immediately, the rotor

may be locked. Release the START switch and return
the REV/OFF/FWD switch to the OFF position.

14. To “bump” the compressor, press the
FAULT/CONT./START switch t the START posi­tion and, holding it there, throw the REV/OFF/
FWD switch to the REV position. If the com-

pressor starts immediately then release both
switches. Repeat step 13 to assure that the com­pressor will run in the forwards direction.

If the compressor does not start immediately

in reverse, then release both switches. A
locked rotor will result in excessive current
being drawn by the compressor.

15. Steps 13 and 14 may be repeated a few times

in an attempt to free a locked rotor, but care
should be taken not to overheat the motor

windings. If the compressor still does not start,

then it should be replaced.

15. Turn off the 220 V AC power source to the HA1.
Disconnect the HA1 test cables from the motor.
