Discrete I/O
Pin Type Description
6 Digital Safe-to-Move Output
Output
Indicates whether the applicator can be moved out of SAFE POSITION to begin paint
application. This output is tied to the arc detection blanking time setting on
The blanking timer begins counting down when high voltage is enabled. When the timer
has reached zero, the Safe-to-Move Output is switched from Inactive to Active.
For more information, see
NOTE: The voltage level for a digital output depends on the type of output selected on
Setup Screen 5 (Digital Output Type Select), page
7 Digital Error Output
Output Used to signal detection of an error condition.
NOTE: Reset by Error Reset input or by local confirmation.

8 Ground I/O Ground
Reference potential for I/O interface signals.
9 Analog Current Setpoint Input
Input
Use to set the current setpoint (µA) nominal value. The REMOTE current setpoint input
applies when Preset 0 (P000) is selected and the controller is in REMOTE operation.
This signal is used to create the current setting in P000. The larger the input value, the
greater the electrostatics current setpoint.
The type of input is selected on
10 Analog Voltage Setpoint Input
Input
Use to set the voltage setpoint (kV) nominal value. The REMOTE voltage setpoint input
applies when Preset 0 (P000) is selected and the controller is in REMOTE operation.
The input voltage or current is used to create a relational output voltage value for
the applicator electrostatics power supply. The larger the input value, the greater the
electrostatics voltage at the applicator.
The type of input is selected on

Inactive: Applicator must not be moved out of SAFE POSITION because arc
detection is blanked and electrostatics are activated.
Active: Applicator allowed to be moved out of SAFE POSITION because arc
detection is active or electrostatics are deactivated.

Inactive: No error condition detected.
Active: An error condition has been detected and reported.
