3. Calculate the Impulse:
a. Determine the wall thickness (0.049 in.).
b. Locate the wall thickness (0.049 in.) and the
corresponding “A” factor in Table 5-3.
Table 5-3 Wall Thickness and “ A ” Factor
Wall Thickness Range
in. mm
“A” Factor
0.015 to 0.045 0,381 to 1,143 1.1
0.046 to 0.083 1,168 to 2,108 1.2
0.084 to 0.109 2,133 to 2,769 1.3
c. Calculate the Impulse using the following formula:
“ A ”
×
wall thickness
×
1000 = switch setting
For example, for a wall thickness of 0.049 in.:
1.2
×
0.049 in.
×
1000 = 58.8 A
d. Set
IMPULSE
(58.8) according to the result of the
formula in step 3.c.
4. Calculate the Maintenance:
a. Locate the wall thickness (0.049 in.) and the
corresponding “B” factor in Table 5-4.
Table 5-4 Wall Thickness and “ B ” Factor
Wall Thickness Range
in. mm
“B” Factor
0.015 to 0.045 0,381 to 1,143 0.25
0.046 to 0.083 1,168 to 2,108 0.30
0.084 to 0.109 2,133 to 2,769 0.40
Note: Because the
IMPULSE
switch
accepts values to only one decimal
place, you may need to round off
the number. Since 58.8 is already to
one decimal place, it does not
need rounding.
Note: If the
IMPULSE
calculation
result is equal to or greater than
99.9 A, set the
IMPULSE
to 99.9.
