Standby Mode - Graco ProBell Electrostatic Controller Instructions And Parts

Standby Mode

Standby mode is when the electrostatics are off
because the system is not ready to perform a
spraying operation. During standby mode, the
following conditions may exist:
• The system is powered down
• Fluid is being loaded
The controller deactivates the electrostatics (if
electrostatics are activated), or prevents the
electrostatics from being activated, when any or a
combination of the following signals are inactive:
