Description
Pin 3 on the Input Power Connection requires line voltage to be applied for
electrostatics to be active. See Step 2 in
used to connect to safety interlock devices using line power.
If not required, bypass the interlock by connecting wire 3 to line voltage on the
Input Power cord. The
the System Interlock is satisfied. See
Pin 19 on the Discrete I/O Cable Connection requires 24 VDC to be applied for
electrostatics to be active. This pin can be used to connect to an external device,
such as a ventilation interlock signal to the controller. Input signal values are:
0 (0 VDC or GND): Interlock not satisfied; electrostatics disabled
1 (24 VDC): interlock satisfied; electrostatics activation is not locked by
this input.
If not required, apply a constant 24 VDC to Pin 19, or see
Disable Controller Interlocks, page 9
Symbol A9 on the display screen (see
this signal is satisfied.
Pin 18 on the Discrete I/O Cable Connection requires 24 VDC to be applied
for electrostatics to be active. Apply only when the applicator is in SAFE
POSITION. See Safe Position Mode, page
24 VDC from this pin will not deactivate the electrostatics.
0 (0 VDC or GND): Interlock not satisfied; If electrostatics are off,
electrostatics disabled. If electrostatics are on, no change to electrostatics.
1 (24 VDC): Interlock satisfied; electrostatics activation is not locked by
this input.
If not required, apply a constant 24 VDC to Pin 18, or see
Disable Controller Interlocks, page 9
