This procedure shows you how to install the 8M Option . 

Machine Compatibility:

• Classic Haas Control:  Mill 8.29 or higher / Lathe 2.16 or higher
   NOTE: M59/M69 Functionality was added in Mill 11.14 and higher.
• Next Generation Control:  All Versions
  
• Hinge door over the I/O PCB.
  IMPORTANT: 93-1000573 I/O DOOR ASSY HINGED order the hinge door if it did not come in the kit.

Document Applies to these Parts:

• 93-1000313 8 SPARE M FUNCTIONS - NGC
• 93-3319 8M FI KIT W/ HINGE DOOR 
• 93-1157A 8M Field Install Kit - CHC

Multiple 8M PCBs Installation

Second 8M PCB Installation:

• 93-3913 2ND 8M SPARE NGC ADDON      

 NOTE: This service kit is intended to upgrade the 8M PCB Bank #2 to include additional spare outputs (spare outputs are restricted for machines with C-APL). This 8M PCB board will be installed directly on top of the first 8M PCB board.  

Third 8M PCB Installation:

•   NOTE: There is no third 8M PCB installation kit. In order to install a third 8M PCB, you will need to order an additional single kit installation (93-1000313 NGC kit or 93-1157A CHC kit) and combine the 12VDC power connector. 

For a single 8M PCB installation.

Install the (4) standoffs [1] to the hinge door .

Install the 8M PCB [2].

Refer to the next section for how to wire and set the jumpers.

Multiple 8M PCB installation

Second 8M PCB Installation.

Remove the existing 8M PCB mounting screws.

Install  the (4) 1 1/4" standaoffs [3].

Install the sencond 8M PCB [4].

Refer to next section for how to wire and set the jumpers.

Third 8M PCB Installation

Choose a location on the hinge door. 

Using the 8M PCB as a template mark the missing holes on the hinge door.

Drill and tap new holes.  (tap size #6-32).

Important:  To protect the I/O PCB from the metal particles,  remove the hinge door before you drill into it.

This step tells you how to install the BRACKET [A] and PCB [F] on Office Mill and Office Lathe machines:

Install the (4) standoffs [1] to the BRACKET [A].

Install the PCB [F].

Use the (4) BOLTS [D].

Install the PCB [F] and BRACKET [A] to the right panel of the control cabinet.

NGC - Next Generation Control: 

You can connect multiple 8M PCB cards daisy chained.  See illustration for cable connections.

Machines without a Non-Servo Autodoor option.

• For 8M PCB # 1 set jumpers at JP1 and JP5 
   Note: This jumper configuration uses Outputs 90 through 97.
  
• For 8M PCB # 2 set  jumpers at JP2 and JP5
   Note: This jumper configuration uses Outputs 103 through 110. There may be a function limitation with this configuration, refer to the M-Code Relay Function - NGC reference document for more information.
• For 8M PCB #3 set jumpers at JP3 and JP5
   Note: This jumper configuration uses Outputs 79 through 86.
  

Machines with a Non-Servo Autodoor option.

• Autodoor 8M PCB:  A 8M PCB is installed at the factory when a machine is ordered with the Autodoor option.  The address jumpers JP4 and JP5 are set from the factory. 
   Note: Do not change this jumper configuration.  This 8M PCB is used for the non servo autodoor operation.
• For 8M PCB # 1 set  jumpers at JP1 and JP5
   Note: This jumper configuration uses Outputs 90 through 97.
• For 8M PCB #2 set jumpers at JP2 and JP5
   Note: This jumper configuration uses Outputs 103 through 110. There may be a function limitation with this configuration, refer to the M-Code Relay Function - NGC reference document for more information.
  
• For 8M PCB #3 set jumpers at JP3 and JP5 
   Note: This jumper configuration uses Outputs 79 through 86.
  
  

The 8M Relay PCB is an option that adds (8) additional outputs to the I/O PCB. Additional outputs can be used to activate probes, auxiliary pumps, or clamping devices.

Please refer to the user manual for detailed descriptions on all of the M-Codes and functions related to the 8M option.

 Note: The 8M PCB option does not provide an output voltage, it only provides an NC or NO switch point for the user interface.

There are two main uses of the 8M:

• Turn relays on (M59) and off (M69)

• Turn relays on while waiting for an external finish signal before turning relay off (Mill: M29, Lathe: M129)

Each M code is followed with a P code. The M codes turns the relay on/off while the P code addesses the discrete relay being turned on/off.  For more information, refer to the M-Code Relay Function - NGC and Robot Integration Aid - NGC reference document.

Corrective Action:

Measure the voltage at P2 on the 8M PCB. Use a multimeter with needle-tip probes. The voltage must be 12 VDC.

 Note: Do not measure the voltage with the cable disconnected.

If the voltage is not correct, measure the voltage at P35 on the PSUP PCB. The voltage must be 12 VDC.

If the voltage is correct, cable 860 is at fault. If the voltage is not correct, troubleshoot the PSUP PCB.

Corrective Action:

Make sure the relays are not damaged. Make sure there is continuity between the contacts on the terminal block:

• Disconnect the cables from the terminal that is at fault.
• Activate the relay. Check for continuity across the Normally Open (NO) contact and the Common (COM) contact.
• De-activate the relay. Check for continuity across the Normally Closed (NC) contact and the (COM) contact.

Make sure the coil of the relay is not open:

• Remove the 8M PCB. On the back of the 8M PCB, measure the resistance across pins 1 and 5 of the relay at fault.
• If the measurement is open, the coil of the relay is open. The 8M PCB is at fault.

This optional cable assembly from the I/O board of the Haas machine to a connector on the side of the control cabinet provides M-code/MFIN capability for controlling external devices. Allows an M-code to pause a CNC program, send a start signal to the device, and then resume the program when an MFIN (finished) signal is received from the device.

Once installed an accessory with a 4-pin male Amphenol 703-91-T-3300-1 screwlocking plug (Haas P/N 74-1510) can be controlled by the CNC machine.

This Document Applies to the following Kits:

• 93-APC-READY AUTOMATIC PALLET CHANGER READY
• 93-1000274    AUTOMATIC PALLET CHANGER READY
• 93-1000651    AUTOMATIC PALLET CHANGER READY
• 93-2395    AUTOMATIC PALLET CHANGER READY, NGC
• 93-2396    CABLE ASSY FOR MCODE/MFIN CAPA, NGC
• 93-1000307    M-CODE/MFIN CABLE ASSEMBLY
• 93-MFININ    CABLE ASSEMBLY FOR MCODE/MFIN CAPA

Turn off power to the machine and open the control cabinet door.

Remove the plug from the side of the control cabinet.

Install the M-FIN connector in the side of the control cabinet. To do so, remove the nut from the plug, insert the wires [1] through the holes from the outside of the control cabinet.

Thread the wires through the nut and tighten the nut [2] against the control cabinet.

Connect the two wires. One pair of wires has a plug on it which is installed to P8 on the NGC I/O PCB.
Note: For Classic Haas Machine connect the plug to P10 on the I/O PCB.

The second pair of wires is made up of a red and black wire. These two wires are installed differently depending on machine options.

If the machine Does Not have an M-Code relay board the wires are connected to the M21 relay on the I/O PCB. Connect the red wire to the M21 N/O (normally open) terminal and the black wire to the M21 COM (common) terminal.

If the machine Does have an M-Code relay board the wires are connected to the M21 relay on the M-Code Relay Board. Connect the red wire to the N/O (normally open) terminal and the black wire to the COM (common) terminal.

Accessories are connected to the CNC control through the M-Fin plug. The accessories are then commanded using the M-Codes.
