Standard Positioner Configuration Settings
Gun to Conveyor
Centerline
(12)
For horizontal positioners, enter the distance from the conveyor
centerline to the tip of guns, with the positioner at zero (full in). This
value must always be a positive number or zero. Refer to page
4-12 for instructions on positioning guns.
For vertical positioners, refer to page 4-12 for instructions on
positioning guns and calculating the value to enter for this setting.
Park/Clean
Position
(13)
This is a position within the positioner range of travel, measured
from zero. This is the position the positioner will go to:
S
when the Park button is touched.
S
when the operation mode is changed from Auto to Manual or
Auto to Off.
S
if the booth interlock signal turns off (exhaust fan is shut off), or
the network malfunctions.
S
when a color change sequence is started (application specific,
consult your Nordson controls engineer).
NOTE: The Park/Clean position should not be greater than the
distance from the forward limit switch to the reverse limit switch.
Retract Position
(14)
Position within the positioner range of travel, measured from the
forward limit switch. This position is used as follows:
S
At system start up, the positioner waits at the Retract position
until valid parts are tracked on the conveyor and the positioner is
commanded to move.
S
If the Lance option is selected, move sequences start from the
Retract position.
For analog positioners (retrofit positioners without an encoder for
position feedback), set this value to the maximum travel distance.
NOTE: The Retract setting should not be greater than the
maximum travel distance (from limit switch to limit switch).
Hysteresis
(15)
Slop compensation distance. Prevents the positioner from hunting
for a commanded position. If the positioner is within this distance of
the commanded position when it stops, it will not move again to try
to stop exactly at the commanded position. Set to a small number
(0.3 − 2.0 in.).
A good starting point is one inch (25 mm). Adjust this value as
needed to prevent hunting, but for the best position accuracy, make
it no larger than needed.
Pickoff
(8)
Distance from the positioner scanners to the guns (leading gun in
horizontal array).
