Operations Near Computers Or Other Electronic Devices - Ransburg 19372 Service Manual

† The quality of atomization can be test-
ed by shooting a "donut" test pattern on a
grounded flat surface at approximately a
15.2 cm (6-inch) target distance. Coarse
atomization may be caused by excessive
fluid delivery (high fluid pressure or wrong
bell size) or improper electrical resistance
of the coating material. Adjust parame-
ters according to atomization quality and
results.
7. Pulling the applicator trigger to obtain mate-
rial flow, move the No. 2 handgun in a smooth
horizontal or vertical line or in a smooth circular
motion, maintaining a constant distance between
the target and the bell surface. (See Ransburg
manual "No. 2 Handgun Spray Techniques".)
8. When complete release the trigger to stop
fluid flow.
9. Turn the "ON - OFF" switch to the "OFF" position.
10. Turn the power switch to the "Off" position on
the power supply.
† For an accurate measurement of paint
delivery with any paint being used, turn the
handgun motor OFF, and remove the bell.
† Using a graduated cylinder or beaker
and a stopwatch, trigger the gun and col-
lect the fluid for one minute. Measure the
paint volume collected to get fluid flow rate
per minute. See maximum "Fluid Delivery
Rate" under "Specifications" in the "Intro-
duction" section of this manual.

For over 50 years, the No. 2 Electric Process
Handgun has been the most widely used tool by
the on-site painting industry for the refinishing
of office furniture, office panels, lockers, school
furniture, and thoussands of other items.
Quite often we are asked about the dangers and
possible damage to computers, phone systems,
word processors, and electronically keyed secu-
rity systems when electrostatic painting is done
nearby.
Concerning those types of applications or any
microprocessor base equipment, the following
facts should be noted:
1. The No. 2 Electric Process Handgun is not
electro-magnetic. It is electrostatic (much like the
static from carpets or wool and synthetic clothing),
and works at an output of 90 kilovolts at 30-50
microamperes current draw. (115 microamperes
maximum short circuit current).
!
† All conductive objects in the area of spray
must be grounded to earth ground. (Ref. EN
50 176, NFPA-33)
2. Unlike x-rays, electrostatic does not go "through"
objects.
3. Some computers, phone systems, or word
processors are now shielded by the manufacturer
against outside static.
4. If the static shielding of a unit is unknown, the
keyboard, CPU (central processing unit), moni-
tor, or phone and its cable preferably should be
removed from the immediate painting area for
protection of the device. If this is not feasible, they
should be completely wrapped in aluminum foil that
is grounded to an earth ground. This will create a
"Faraday cage" around the computerized device.
