Table 1 Electrostatic Interlock Information
Interlock
Pin
Description
System
Interlock
Input power
cord, Pin 3
(wire 3)
Pin 3 on the Input Power Connection requires line voltage to be applied for
electrostatics to be active. See Step 2 in
. This pin can be
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
icon is displayed on the controller screen when
the System Interlock is satisfied. See
.
24 VDC
Interlock
Discrete
I/O cable,
pin 19
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
) will show that
this signal is satisfied.
SAFE
POSITION
Interlock
Discrete
I/O cable,
pin 18
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
. If electrostatics are on, removing
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
Symbol A10 on the display screen (see
) will show that
this signal is satisfied.
