The output current is a function of the line voltage, which
must be sinusoidal and have good regulation.
If the Test Kit
RESET lamp will not light, check to make
sure that no trip LED’s are lit on the Trip Unit. If so, press
the “trip reset” pushbutton on the face of the Trip Unit.
2.2 CIRCUIT BREAKER INFORMATION
2.2.1 TRIP UNIT TOLERANCE BANDS
Long Delay Times of the Trip Unit are top of band,
therefore expect shorter times when testing.
Short Time, Instantaneous, and Ground Fault values
are mid-band, which have +/- 10% tolerance.
2.2.2 TRIP UNIT TEST GUIDELINES
Testing of the Trip Unit must be performed with the Trip
Unit properly installed in the breaker.
The long time function has a memory circuit with a reset
time of 36 times the long delay time setting; i.e., for a LDT
setting of 4 seconds the reset time is 144 seconds (36x4).
Therefore, for long delay time tests, there must be a time
delay greater than the calculated reset time or the ac
control power to the Trip Unit must be interrupted between
tests to clear the memory circuit. To do this, remove the ac
supply to the Auxiliary Power Module rather than discon-
necting the plug from the Test Kit Adapter. A thermal
memory jumper may need to be repositioned to the
“inactive” position to disable the thermal memory. This
jumper is shipped from the factory in the “active” position.
If a trip function LED on the Trip Unit is lit prior to a test,
press the “trip reset” pushbutton on the Trip Unit.
When bench testing a breaker wired for zone interlock
applications, shorting plug 8779C02G06 must be installed
per Figure 5.
SECTION 3: CHECKING THE TEST KIT
3.1 GENERAL INFORMATION
This check should be performed when the Test Kit is first
received, or for a maintenance check. A more rigorous
check would be to perform all Trip Unit tests on a standard
Trip Unit.
3.2 HARDWARE CONNECTIONS (REFER TO FIGURE 2)
1.
Connect the 11-pin banana plug on the Test Kit to the
corresponding port on the Test Kit Adapter.
2.
Connect the 14-pin plug from the Test Kit Adapter into
the corresponding test port on the Trip Unit.
3.3 SETTING THE TEST KIT
1.
TIMER ON/OFF switch to “OFF”.
2.
HI / LO AMPS switch to “LO AMPS”.
3.
CURRENT ADJUSTMENT to “ZERO”.
3.4 TESTING THE TEST KIT
1.
Plug the APM and the Test Kit into 120 volt, 60 Hz
source. (Test Kit can be used on 50 Hz but timer
readings must be multiplied by 6/5.)
2.
Turn the Test Kit
POWER ON/OFF switch “ON”.
2A.
POWER ON/OFF pilot lamp (red) should light.
2B.
RESET pilot lamp (amber) should light. If RESET pilot
lamp is not lit, push
RESET button. RESET pilot lamp
should then light.
3.
Turn
TIMER ON/OFF switch to “ON”. Timer should not
run.
4.
Push
TEST button.
4A.
TEST pilot lamp (red) should light.
4B.
RESET pilot lamp (amber) should go out.
4C.
TIMER should operate, counting seconds.
5.
Operate
STOP toggle switch (momentary) to “STOP”.
5A.
TIMER should stop.
5B.
RESET pilot lamp (amber) should light.
5C.
TEST pilot lamp (red) should go out.
6.
Push manual
RESET button on timer. TIMER should
reset to zero.
7.
Hold
CALIB toggle switch (momentary) in “CALIB”
position and turn
CURRENT ADJUSTMENT knob from
zero to maximum. Ammeter should read from zero to
approximately 8 amperes.
