Safe Position Mode
The SAFE POSITION is defined as a position where
the applicator electrode is at least 6 inches away from
any grounded object. While many such positions
may exist, one position should be selected as the
applicator SAFE POSITION. When the applicator
is in the SAFE POSITION, electrostatics can be
activated, blanking time allowed to elapse, and arc
detection activated. The applicator should remain in
the SAFE POSITION until the system reaches full
voltage and arc detection is active.
To enable electrostatics using SAFE POSITION:
1. Satisfy the System and 24 VDC interlocks.
2. If controlling the system through the discrete I/O
interface, set the REMOTE input high.
3. Move the applicator to SAFE POSITION. Then
set the SAFE POSITION interlock high to tell the
Electrostatic Controller that the applicator is in
SAFE POSITION and that the electrostatics can
be activated.
4. Set the Electrostatic Enable input high or activate
the electrostatics.

5. The Electrostatic Controller activates the
electrostatics at the applicator.
6. The Safe-to-Move output is activated when
the time defined by the arc detection
blanking parameter (C1) value, as defined on
Setup Screen 11 (Transition Time), page
elapsed after receiving the Electrostatic Enable
input signal. The Safe-to-Move signal indicates
that the controller has determined that the
applicator electrostatics are ready for application
and that the applicator can move freely.
Arc detection is deactivated during the blanking
time. The C1 setting defines the length of time
before arc detection is enabled.
When the applicator leaves the SAFE POSITION,
the SAFE POSITION Interlock is removed, which
leaves it not satisfied. This does not disable the
electrostatics. If the electrostatics are deactivated,
the robot needs to return to the SAFE POSITION and
reapply the SAFE POSITION Interlock input in order
to activate the electrostatics.
