UEi Test Instruments HA1 - Manual (Page 2)

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 posi-
tion 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 com-
pressor 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.
