3. Feed these wires through the top right opening in
the electronics control panel.
4. Connect terminal block 11 (C11) to the gun's
electrostatic controller with the signal wire.
-
When the output is inactive terminal block 11
(C11) has 4-5V present.
-
When the output is active there is 24V present.
5. Connect terminal block 12 (C12) to the ground wire.
NOTE: Terminal block 11 (C11) signal voltage is
optically isolated at Graco electrostatic controllers. If
using any other controller be sure to use an
optocoupler at the input to the device.
NOTICE
To prevent damage to equipment, do not use these
terminal blocks without an optocoupler present.
