Calculating Melter Power Requirements
A-2
Part 1032059B
E 2003 Nordson Corporation
Manual 41-DURABLUE-MA-02
To evaluate the hose/gun power requirements
1. Identify all hose/gun pairs based on the hose/gun receptacle to which
they are connected.
2. Examine the identification tag or plate on each hose and gun and record
the wattage of each in Column A of Table A-1. Enter a zero for any hose
or gun that is not installed.
3. Add the wattages of each hose/gun pair and place the sum in Column B
of Table A-1.
4. Add the wattages of hose/gun pairs 1 and 2 and place the sum in
Column C of Table A-1.
5. Compare each of the wattages tabulated in Columns A, B, and C of
Table A-1 with the associated maximum allowable wattages in Table A-2
for 240 VAC melters or Table A-3 for 120 VAC melters.
6. Do one of the following:
S If each of the wattages calculated in step 5 do not exceed the
associated maximum allowable wattages listed in Tables A-2 and
A-3, then the power required by the hoses and guns is within
acceptable limits.
S If any of the wattages calculated in step 5 does exceed an
associated maximum allowable wattage listed in Tables A-2 and A-3,
then the configuration or position of the hose/gun pairs must be
rearranged, shorter hoses must be used, or lower power guns must
be used in order to reduce the power requirement.
