Graco ProBell Electrostatic Controller Instructions And Parts page 11

Basic Integration
To reduce the risk of fire and explosion, the
Electrostatic Controller (A) must be electrically
interlocked with the spray booth ventilation fans
to prevent the applicator from operating unless
ventilation air flow is above the minimum required
value.
The defining characteristics of a Basic Integration
installation include:
• Integration of basic applicator and controller
functions.
• Integration of controller interlocks.
• Local operation of setup and error functions.

Typical Installation With Basic Integration
3A3657C
This example shows a basic integration that uses 6
of the 19 signals available on the Discrete I/O cable.
• Preset Select 1 (Pin 1) and Preset Select 2 (Pin 2):
Used to select Presets P000-P003. For example:
Select Preset P002 by applying 24V to Pin 2 and
Ground or no connection to Pin 1.
• Remote Enable/Disable (Pin 4): Enable remote
control through the Discrete I/O interface by
applying 24V to Pin 4.
• Electrostatic Enable (Pin 5): Use a switched
voltage source for Pin 5 to activate/trigger the
electrostatics.
• GND (Pins 8, 12, 17): Used as ground reference
for I/O signals.
• Interlocks: See
on how to set up the required interlocks.
