BRAKE AIR
Brake air is used to slow the turbine speed in
a minimum length of time. It is advantageous
for short cycle times during color change, or
may be used to reduce speed or stop the tur-
bine. Never operate brake air with the turbine
air on.
Approximate brake times to reduce the turbine
speed are shown in “Deceleration Time Chart”
in the “Introduction” section. These times are
based on 60 psi (413.7 kPa) and 100 psi (689
kPa) air pressure at the back of applicator.
ELECTROSTATIC VOLTAGE
The RMA-303 Rotary Atomizer receives a low
voltage control input from the MicroPak to
control the operating electrostatic voltage.
(refer to the current “MicroPak” manual for
detailed for operating instructions.)
N O T E
If paint defects occur, such as fatty edges or
picture framing, reducing the voltage should
be a last resort. To correct the problem, lead
and lag trigger adjustments should be opti-
mized first.
The electrostatic voltage applied to the RMA-
303 will affect pattern size, transfer efficiency,
wrap and penetration into cavity areas. A set-
ting of 30-100 kV is appropriate for most appli-
cations.
