Push [POWER OFF].

Open the control cabinet.

Set the main circuit breaker to the OFF position. Lock the main circuit breaker. Use an approved lock with an approved safety tag.

Clean the surface of the cross slide [3]. For a TL-1, put the turret [2] onto the cross slide [3]. For a TL-2, put the riser plate [4] onto the cross slide [3]. Keep the screws [1] sufficiently loose for turret alignment.

If the machine has a tool-changer air-pressure regulator, go to Step 3.

Find the pemnuts on the rear of the machine and left of the control cabinet. Install the included regulator [1] to the pemnuts.

Close the primary air valve. Connect the shop air hose [2] to the regulator input. Connect 11' (3 m) of 1/4" (6 mm) air tube [3] to the regulator output. Pull the air tube [3] through the bottom of the control cabinet.

 Danger: If the vector voltage indicator light is on, do not touch the electrical components. The high voltage in the control cabinet can kill you. Wait for the vector voltage indicator LED to go off fully.

Put the 30-Amp servo amplifier into the amplifier bank section that has the label "Tool Turret".

Connect the power wires to the high voltage terminals on the amplifier:

• red to RED [1]
• white to WHT [2]
• black to BLK [3]

Connect the current command cable [4] to the connector at the top of the amplifier.

Install the jumpers [5] from the nearest amplifier to the 30-Amp servo-amplifier:

• Connect the black wire to -H.V.
• Connect the red wire to +H.V.

Connect the current command cable [1] from the amplifier to P5 on the Mocon PCB.

Find the encoder cable [2] for the turret motor. Connect the encoder cable to P9 on the Mocon PCB.

 Note: On some machines, the position of the PCBs is different than the illustration.

Pull the encoder cable [2] through the bottom of the control cabinet.

Connect the air solenoid cable [3] to P55 on the I/O board. Put the other end of the air solenoid cable [3] to the bottom of the control cabinet.

Put these cables through the bottom opening of the control cabinet:

• Air Hose running from the regulator
• Air Solenoid Cable
• Home Switch Cable
• Turret Power Cable
• Turret Encoder Cable

Put the cables through the split flex conduit bracket and into the conduit [1].

Put the conduit over the control mount base. Put it adjacent to the X-axis motor cable conduit [3]. Attach each conduit to the control mount base. Use the clamp block [2].

Put the conduit [4] to the rear of the cross slide. Put the conduit correctly in the clamp block [6]. Put the conduit correctly in cable clamp [5].

Remove the cover [1] for the turret servo-motor. Remove the cross-slide waycover [6].

Pull the conduit [2] along the tray at the bottom of the cross-slide cable channel. Pull the conduit [2] through the opening [4] on the front of the cross-slide. Put the conduit through the cable clamp [3] on the motor assembly.

Connect the electrical cables to the bracket [5]. Connect the air hose to the air fitting [7]. Connect the power cable [8], motor encoder cable [9], TC solenoid cable [10], and the home switch cable [11].

Put all of the connectors under the motor cover [1]. Coolant can cause damage to the connectors if you put them in the lower cross-slide channel.

Install the cover for the turret motor.

Set the main circuit breaker to the ON position.

Start the air supply to the machine. Set the tool-changer air-regulator pressure to 80 psi (5.5 bar). Open the primary air valve.

Push [POWER ON].

Look at the TT-4 identification plate [1].

 Note: Turrets made after December 2014 have the values for Parameters 128 and 212 on the identification plate.

If the parameter values are not on the identification plate. Go to the next section ("Parameter Setup - Parameters 128 and 212").

If the values are on the identification plate:

• Set Parameters 128 and 212 to the values on the identification plate.
• Set Setting 7 (Parameter Lock) to ON.
• Do not do section ("Parameter Setup - Parameters 128 and 212").

Set the A-Axis Grid Offset. Do these steps:

Set Setting 7, Parameter Lock, to OFF.

Set Parameters 128 and 212 to values of 0.

Push [RESET] to stop each alarm. Go into DEBUG mode.

Push [ZERO RETURN]. Push [A]. Push [SINGLE].

 Note: Ignore the ZERO RETURN MARGIN TOO SMALL alarm.

Type GRID A on the Raw Data Screen.

Make sure that Parameter 128 has a value [1].

If Parameter 128 does not have a value, do this step again.

Set the Tool Change Offset, as follows:

Set Parameter 43 bit 18 (Invis Axis) to zero.

Go into [MDI] mode. Set the turret to tool 1 (T1). Use M43 to unclamp (disengage) the turret.

Push [EMERGENCY STOP] when the tool turret [1] is in the unclamped (disengaged) position [2].

Manually move the turret to tool 1.

Release [EMERGENCY STOP].

Push [RESET].

Use M44 to clamp the turret.

Make sure turret clamps (engages) fully. If the turret does not clamp fully, do this step again.

Push [EMERGENCY STOP].

Go to the POS-RAW-DATA screen.

Record the ACTUAL A-Axis position [1].

 Note: In this example the ACTUAL A-Axis position is 0.6612.

Go to Parameter 212.

Type the opposite value of the ACTUAL A-Axis position [1].

 Note: For example the ACTUAL A-Axis position 0.6612 becomes -0.6612.

Make sure the turret clamps correctly.

If the turret does not correctly clamp, do steps 2 and 3 again.

Go out of DEBUG mode.

Push [ZERO RETURN]. Push [A]. Push [SINGLE].

Make sure the tool changer operates correctly. Operate this code in [MDI] mode:

For TT-4 and ATT-4:

T1; T2; T3; T4; T3; T2; M99;

For ATT-8:

T1; T2; T3; T4; T5; T6; T7; T8; T7; T6; T5; T4; T3; T2; M99;

Set Parameter 43 bit 18 [1] to 1.

Set Setting 7, Parameter Lock, to ON.

Install the (4) metal shims [2].

 Note: Be prepared to grind the shims to the correct thickness when you align the turret.

Do not tighten the turret mounting screws [1] at this time.

Make sure the tool turret is flat on the Z Axis. Do these steps:

Put a magnetic base indicator [1] on the spindle casting.

Put the tip of the indicator on the bottom inner surface [2] of the tool turret.

Put the indicator tip parallel to the Z Axis.

Jog the Z Axis.

Measure the alignment of the tool changer along the full surface.

The error cannot be more than 0.002" (0.05 mm) across 5.5" (140 mm) of travel.

Record the error.

Make sure the tool turret is flat on the X Axis. Do these steps:

Put the tip of the indicator on the bottom inner surface [1] of the tool turret.

Put the indicator tip parallel to the X Axis.

Jog the X Axis.

Measure the alignment of the tool turret along the full surface.

Record your indicated values.

The error cannot be more than 0.002" (0.05 mm) across 5.5" (140 mm) of travel.

If the error is too large, do these steps:

• To increase the height of the turret, add mylar shims.
• Add mylar shims between the metal shims and turret.
• To decrease the height of the turret, grind the metal shims.
• Do steps 2 thru 3 again.

Make sure the tool turret is parallel with the X Axis. Do these steps:

Put the indicator tip against the inner vertical surface [1] of the tool turret.

Put the indicator tip parallel to the X Axis.

Jog the X Axis.

Measure the alignment of the tool changer along the full surface.

The error cannot be more than 0.001" (0.03 mm) across 5.5" (140 mm) of travel.

If the error is too large, make adjustments.

To make adjustments, lightly tap the base of the turret.

Use a soft mallet.

Make sure the tool turret aligns with the spindle centerline. Do these steps:

Install a toolholder [4] at tool position 1.

Put a 1" (25.4 mm) collet holder [3] in the toolholder.

Attach an indicator [2] to the center of a spindle alignment bar (P/N T-1312) [1].

Jog the X Axis to put the collet holder at the center of the spindle.

Manually turn the spindle 360 degrees.

This measures the error on the inner diameter of the collet holder.

The radial error cannot be more than 0.001" (0.0254 mm) around the circumference of the internal diameter.

If the error is too large, do these steps:

• To increase the height of the turret, add mylar shims.
• Add mylar shims between the metal shims and turret.
• To decrease the height of the turret, grind the metal shims.
• Do steps 2 thru 5 again.

Tighten the (4) 5/8" x 11 SHCS [1].

Tighten to the specified torque values.

 Note: Torque the screws. Refer to Haas Fastener Torque Specifications. Use the value for steel.

Do steps 2 thru 5 again to make sure the alignment is correct.

Make sure the tool changer operates corrrectly. Operate this code [1] in [MDI] mode:

T1; T2; T3; T4; T3; T2; M99;
