to save the original fasteners for re-assembly.
Step 3 -
Cut a piece of one inch wide
drafting/masking tape approximately 8 to 10 inches
long.
Step 4 -
Place the tape around the cam starting from
the bottom up. Make certain that the tape adheres
well to the cam surface. (See Figures
6-7, 6-8
and
6-
9
)
.
Step 5 -
Mount the transparent CloSure
TM
Test Tool
with two bolts and washers. Refer to Figures
6-20, 6-
21
and Table
6.4
for appropriate mounting holes.
Hand tighten the bolts (Figures
6-10, 6-11, 6-20
and
6-21
).
Step 6 -
A Sanford
®
Sharpie
®
black fine point
permanent marker, item no. 30001, is recommended for
this next step. Place the marker tip in the proper hole
(
“
C
”
).
Refer to Figure
6-20
and make a heavy mark on
the tape as shown in Figure
6-13.
Step 7 -
Charge the closing springs with the
maintenance tool. Continue charging the closing
springs until a
“
click
”
is heard and the status indicator
shows
“
Charged”
(Figure
6-12
).
Step 8 -
While holding the marker tip on the tape, close
the breaker (Figure
6-13
).
Step 9 -
Move the marker back and forth horizontally
approximately 15
o
in both directions to create a line on
the tape that identifies the closed rest position (Figures
6-14, 6-20
and
6-16
).
Step 10 -
Remove the marker from hole
“
C
”
.
Step 11 -
Push the
“
push to open
”
clapper to open the
circuit breaker.
Step 12 -
Inspect the circuit breaker to assure it is in the
Figure 6-8 Wrapping Tape Up Around Cam
open position and the closing springs are discharged.
Remove the transparent CloSure
TM
Tool. Remove the
tape from the cam and stick the tape on the front right
side sheet of the circuit breaker. Record the date of the
test and the operations counter reading on the tape
(Figures
6-17
and
6-18
and
6-19
).
Step 13 -
Evaluate the CloSure
TM”
performance by
comparing the test tape with the illustrations in Figure
6-19.
If the marking is similar to
6-1 9A,
measure the
over travel
“
x
”
:
If “x” is greater than or equal to 0.6
inches, the circuit breaker performance is satisfactory.
If “x” is less than 0.6 inches or if the marking is similar
to
6-19B
or
6-19C,
immediately contact the Product
Integrity Center for Technical Support at (412) 787-
6518.
Step 14 -
Remove the CloSure
TM
Tool. Reassemble the
front cover onto the circuit breaker. Return the circuit
breaker to it
