Burford 2000 - Bagger-Active Circuit; Counter Output; External Counter Output

 Bagger-Active Circuit
This signal from the bagger to the Servo Tyer indicates the status of the bagger and it
must be the same voltage as CR3 on the main electrical panel. This signal can be taken
from across the coil of the clutch relay of most baggers. This signal drives the coil of a
mechanical relay, which starts and stops the brush motor and gathering belts of the Servo
Tyer. This connection is used to prevent the Servo Tyer gathering belts and brushes from
running while the bagger is stopped. This will prevent a package from being pulled forward
over a conveyor flight and will also reduce wear on the brushes and conserve energy
during long breaks or periods of maintenance in other areas. This connection can be
made using wires 40 and 43 in the flexible conduit coming from the Main Enclosure. Wire
40 should be connected to the Line side of the coil and wire 43 should be connected to
the Neutral side of the coil. For setup and testing, the gathering belts and brushes can be
made to run while the bagger is inactive by placing the switch on the front of the Main
Enclosure marked “BELT/BRUSHES” in the “ON” position.
 Counter Output / External Counter Output
The Servo Tyer comes standard with a relay (CR3), which toggles when a valid package
is tied. This relay is normally used to drive a customer's external counter, but it can be
adapted to serve other functions with external customer logic. This relay does not toggle
if the tie cycle is aborted or if a heel is detected in the tie.
If an external counter is desired, a set of dry contacts are supplied as an input to the
customer's counter. The External Counter relay (CR3) is mounted in the Tyer’s electrical
enclosure. Connection can be made using wires 41 and 42 in the flexible conduit coming
from the main enclosure. The contacts actuate for a period of about 1/4 second
immediately after a successful tie has been completed. These contacts will not actuate if
the tyer aborts its tie cycle or if the tyer determines that extra material is in the bag neck,
such as a heel. The contacts can be configured to be normally open or normally closed
by using DIP Switch 2 on the AMP board see pg.87.
Wires 40 & 43 should be wired into the bagger so anytime the
bagger is “CYCLING”, 110 VAC is supplied to these wires.
