front plate). To decrease the speed of the pressure bar INWARD, turn the knob (B) counter clockwise. To
decrease the speed of the pressure bar INWARD, turn the knob (B) clockwise. To increase the speed of the
pressure bar OUTWARD, turn the knob (A) counter clockwise. To decrease the speed of the pressure bar
OUTWARD, turn the knob (A) clockwise. Adjust the speed of the pressure bar so that it moves in and out
rapidly, in a fluid manner, without causing the pressure bar to "bang" in or out.
4.11 Pressure Bar (Rubber) Replacement
Located along the inside of the pressure bar is a strip of rubber, held on the pressure bar by a channel,
pressing on the edges of the rubber. The rubber compresses against the front (gripper) plate holding the
bag in place during sealing and during bag tear off. If the rubber becomes brittle, torn, gouged or otherwise
worn, it should be replaced to assure strong seals.
To replace the pressure bar rubber, simply pull one end of the rubber from the channel. The rubber will
come out of the channel quickly and easily. To install a fresh piece of rubber, press one edge of the rubber
into the channel then the other edge. Work the rubber into the channel in small increments along the length
of the channel (Fig. 4-20). If you used Teflon tape to cover the surface of the rubber, place the Teflon on
the rubber along its length. If the Teflon extends beyond the rubber, cut off the excess.
Note: Teflon may be added to the pressure bar rubber if the bag sticks to the rubber after loading and
sealing. The bag may stick to the rubber if the product and bag is light in weight and if the rubber is dirty.
Note: Frequently clean the rubber with alcohol to remove buildup of dirt or other contaminants.

4.12 Antijam Adjustment

The antijam device is designed to protect the T-1000 from damage when an obstruction is encountered in
the seal area (area between the pressure bar and front (gripper) plate). If properly adjusted, the pressure
bar will retract if an obstruction is encountered in the seal area. The pressure bar houses springs which
cause the rubber and holder to compress. When the rubber holder compresses, a sensor is activated causing
the pressure bar to retract. The sensor is defeated when the pressure bar is approximately 1/8" from the
gripper plate (Fig. 4-21). The antijam can quickly be tested while the T-1000 is operating using care, but
should be thoroughly tested by disconnecting air and power and removing covers.
To quickly test the antijam device, place a 3/8" diameter flexible poly tube against the front (gripper) plate
perpendicular to the seal bar opening. Press the foot switch allowing the pressure bar to compress the poly
tube against the front plate. If the pressure bar does not immediately retract and place the T-1000 in the
STOP mode, the antijam device is not properly adjusted. Test the antijam device along the entire length of
the pressure bar using the 3/8" poly tubing as a test device.
CAUTION: To avoid personal injury, do not place fingers or hands into the seal area of the
T-1000 while power is ON or air is attached. Do not test the antijam device with hands or fingers.
Ensure the poly tube which is used for testing is long enough to keep fingers or hands away from the seal
area of the T-1000.
To thoroughly test and adjust the antijam device, you must first turn the power to the OFF position,
disconnect the air line from the T-1000 and remove the top and left side cover. With the covers removed
and air disconnected, turn the power to the ON position.
To test the pressure bar sensor, locate the "X4" LED on the PLC Board (Fig. 4-8) and ensure the light is
illuminated (ON). Then, compress the rubber and holder into the pressure bar (nylon holder). As soon as
the rubber is pressed into the nylon holder, the "X4" LED should turn OFF. The LED should remain OFF
while the rubber is held compressed into the nylon holder. If the "X4" LED shuts OFF while the rubber
bar is pressed into the nylon holder, the pressure bar sensor is functioning properly.
