Installation
b.
Connect the gun air supply line (K) between
the ProMix gun air outlet
and the gun air
inlet.
NOTE:
Install an air shut off valve in the gun air
supply line or at the gun air inlet.
WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of fire and explosion,
an automatic shutoff valve must be
properly installed in the gun air line if using a Graco
electrostatic PRO
Gun.
Contact your Graco representative for information
on air shutoff valves for electrostatic applications.
10. Plug the operator station (77) into the connec-
tor
on the ProMix control, using the 50 ft. cable
supplied. See Fig. 1 and 4.
Mount the operator station in an area where the
operator can easily access it.
WARNING
FIRE AND EXPLOSION HAZARD
The ProMix control is intrinsically safe
when used without any external electri-
cal components connected to it. If an
external power supply or printer is
connected to the control, the control is
no longer intrinsically safe and the
control, as well as the power supply and printer,
must not be operated in hazardous locations, as
defined in article 500 of the National Electrical
Code (USA) or your local electrical code.
11. If using a printer, plug the printer cable into the
printer cable connector
on the ProMix control.
See Fig. 4.
12. If the external power option is used instead of the
air driven power supply (74) inside the control,
disconnect the wire harness from the power supply
connector (74b). See Fig. 5.
Plug the power cable into the external power
connector
. See Fig. 4, page 11. Use a 12–18
Vdc, 0.3 amp power supply. Do not exceed the
+24 volts maximum applied voltage.
13. If the alarm option is used, connect an air line
between the alarm air outlet
on the control and
the air inlet on the alarm. See Fig. 4.
