3. Safety Skirt

Attach the trough cover [1] to the CHIP CONVEYOR.

For a Jorgensen conveyor, install the (8) hex head screws and washers to attach the trough cover and lock the conveyor in the operating position as shown.

For a Hennig conveyor, install the (4) hex head screws and washers to attach the trough cover and lock the conveyor in the operating position.

Lift the chip conveyor.

Slide the drip tray under the chip conveyor to the approximate position shown in the figure.

 Note: No fasteners are needed to keep the tray in place.

For ST-40/40L models, unfold and lock the leg before operation. The leg height needs to be adjusted so that the casters touch the floor after the machine is leveled.

Open the cover at the head of the conveyor. Look at the belt tension as the belt goes around the sprocket.

Tighten the belt tensioning screws at either side of the conveyor head to adjust the belt drive shaft and remove slack from the belt.

 Note: Adjust the screws equally to keep the drive shaft perpendicular to belt travel.

While you adjust the belt tensioning screws, push up on the belt with a wrench at the head of the conveyor. Measure the belt slack [1] at the center of the belt in the lift section of the conveyor. The correct belt slack for Jorgensen conveyors is 0.25" - 0.38" (6 - 10 mm). The correct belt slack for Hennig conveyors is 0.12" - 0.25" (3 - 6 mm). Repeat step 2 as needed.

Apply the jam nut on each tensioning screw to lock it in place.

Install the access cover.

Attach the skirt [1] to the bracket [2].

Note: The seam [3] in the skirt faces the conveyor as shown.

Mount the bracket to the conveyor.

• TL-2    93-1000483

If the chip conveyor is a field install follow the Field Install section below.

If the machine is a new install with a chip conveyor follow the Machine Install section below.

Remove the chip conveyor shipping bracket and install the tailstock stop hardware that is found inside the machine.

Install the lower bracket hardware.

Lower the chip conveyor leg to the extended position.

Turn on the machine.

Login to the HAAS SERVICE PORTAL.

Download the Chip Conveyor option configuration patch files.

Note: The option files will appear on the configuration download page after the Chip Conveyor Kit has been ordered.  If the option does not appear contact the service department.

Load the option configuration patch file to the control.  Refer to the NEXT GENERATION CONTROL - CONFIGURATION FILE - DOWNLOAD/LOAD procedure.

Test the chip conveyor by pressing the [CHIP FWD],  [CHIP STOP], and [CHIP REV] buttons on the control pendant.

This procedure tells you how to install and wire a replacement motor for a conveyor. When you receive the replacement motor, the cable for the motor will have one of these circumstances:

• The cable may match your existing electrical cable. In this circumstance, no modification is necessary.
• The cable may not match your existing electrical cable. In this circumstance, you have (2) options:
  • You can bypass the extension cable on the machine and connect the new motor cable directly to the I/O PCB.
  • You can take the cable off of the old motor and install it onto the new one. This procedure shows you how to make that modification.

Use P/N 93-1224B for vertical mills and lathes. Use P/N 93-2381 for horizontal mills.

Corrective Action:

Inspect the motor cable for any sign of damage. Check for burn marks at the plug. This could be caused by coolant contamination.

Measure the Ohms the across the motor power cable leads [1] at the plug. There should be resistance leg to leg. An open reading suggests a bad motor or cable.

Measure the Ohms on the motor power cable from each power leg to the ground leg [2] of the plug. This reading should be open.

If cable shows a short leg to ground at the plug, disconnect the power cable at the motor and check each motor power lead to the motor chassis [3]. If reading is open, the cable is at fault. If any lead tests short, the motor is motor is shorted.

Corrective Action:

Find the chip conveyor motor cable 140 at the I/O PCB. Press [CHIP FWD]. Use a multimeter with needle tip probes to measure the voltage between the black and red wires on the cable.

Have someone press and hold [CHIP REV]. Measure the voltage between the black and white wires. When the I/O PCB operates correctly, each voltage reading is 240 VAC.

If the voltage at the I/O PCB is correct, open the conveyor motor junction box. Use a multimeter with needle tip probes to check for voltage on the power leads at the motor.

If there is no voltage, check the motor and the cable. If there is voltage, check the capacitor. If you verify the voltage and capacitor are correct, inspect the motor drive shaft and keyway.

Corrective Action:

Check these fuses at the bottom right corner of the I/O PCB (Fuse type: AGC 5 amp):

• Single phase motors: FU2 [1] /FU3 [2]. There should be no fuse in FU4 [3].
• 3 phase motors: FU2 [1] /FU3 [2] /FU4 [3]

A short in the motor or the cable could have blown the fuse

Corrective Action:

Inspect the conveyor motor capacitor for damage. A damaged capacitor will usually have signs of deformation or bubbling on the capacitor casing. This could be caused by a short in the motor or in the cable.

Open the motor junction box. Check the capacitor. Look for burn marks on the case.

Measure the capacitor. Most multimeters can measure capacitance upon manual activation (turn to the correct units of measurement, and push the yellow button). It should be 6 or 9 microfarad as noted on the capacitor's case.

Corrective Action:

Inspect the conveyor belt for damage.

Corrective Action:

Make sure the belt tension is correct. Refer to the decals on the side of the machine. The correct belt slack for Jorgensen conveyors is 0.25" - 0.38" (6 - 10 mm). The correct belt slack for Hennig conveyors is 0.12" - 0.25" (3 - 6 mm).
