Run Screen 2 (Arc Limits) - Graco ProBell Electrostatic Controller Instructions And Parts

Operation

Run Screen 2 (Arc Limits)

Run Screen 2 is the secondary screen for the
electrostatic applicator. This screen shows the active
Preset, arc detection limits, and screen backlight
brightness. Screen backlight brightness is set 0–8,
with zero being Off and 8 being the brightest. NOTE:
The screen will dim automatically after 5 minutes
of inactivity. The screen backlight brightness is not
reset if factory defaults are restored.
Arc detection is a safety feature of the Electrostatic
Controller. Arc detection is used to detect when
grounded objects are too close to the electrostatic
spraying device. If this occurs, the controller shuts
down electrostatic generation instead of creating an
electrical discharge.
The static arc limit is used to detect a grounded
object that is stationary or slow moving. The dynamic
arc limit is used to detect grounded object that is fast
moving. For both static and dynamic arc limits, lower
values are more sensitive than higher values.

NOTE: It is recommended that arc detection settings
not be changed from defaults. Any desired change
must be set individually for every Preset.
The set points are locked. To change the setpoints,
press and hold both of the T1/T2 or both of the
T3/T4 arrows simultaneously. The setpoint numbers
will turn red. Use arrows T1 and T2 to change the
static arc limit. Use arrows T3 and T4 to change the
dynamic arc limit. Arc detection parameters relock
after 4 seconds or when the screen is exited.
