Description

The MASSO G3 Touch wiring module is an extension module used to extend inputs and outputs from inside the MASSO G3 Touch cabinet to a machine location (usually on the machine itself).

Using this module simplifies cable management between the MASSO G3 Touch and the machine. If cables are damaged, they can be replaced quickly and easily.

What’s Included

The extension kit includes:

• Local extension module board (plugs into MASSO Touch)

• 4 short hex brass spacers (to replace the ones in MASSO)

• D cables to connect the two boards

• Machine-side extension module (for wiring inputs and outputs)

Features

Local Side

• Connectors for Inputs 1, 2, and Estop: Allows reconnection of front buttons and Estop

• Access port for the onboard battery

Machine Side

• Fuse holder for a 1 amp fuse (powers MASSO G3 Touch)

• Power supplied at machine-side board and sent via extension cables

• 24 DIP switches for enabling pull-up resistors on inputs

• Optical isolation for Spindle CW and CCW outputs

• DIN rail mount for installation

Installing your MASSO G3 Touch Wiring Module

Step 1

Open your MASSO G3 Touch cabinet

Step 2

• Remove the top label and keep the 4 screws aside

• Remove wires from:

  • Inputs 1 & 2

  • POWER

  • Estop 2

• Remove all connectors and keep them for later

Check spacers

• Compare supplied brass spacers with existing ones

• If same length - no change needed

• If shorter - replace existing spacers one at a time
   

  
   

Step 3

Install the local extension board onto MASSO G3 Touch

• Connectors are keyed - only fit one way

• Ensure correct orientation:

  • Connector side facing MASSO

  • 37-pin connectors facing bottom

Take care:

• Ensure red and green LEDs are straight

• The board has holes to view LEDs

Check installation

• Ensure the board is fully seated

• If not:

  • Check spacers are not blocking

  • Press boards together evenly along both sides

Step 5

• With Pendant: - go to Step 6

• Without Pendant:

  • Connect black wire to Estop 2

  • Go to Step 7

Step 6 (With Pendant)

Step 7

Connect wires as follows:

• Terminal 1 - Green wire (Input 1)

• Terminal 2 - Blue wire (Input 2)

• Terminal 3 - Yellow/Red/White wires (Power to MASSO)

• If no external Estop is used, continue to Step 9

• If using external Estop, continue to Step 8

Step 8 (External Estop)

 

• Connect the red wire to Terminal 4

Step 9

• Pass both 37-pin cables through the cabinet slot

• Ensure one male and one female connector

• Connect them to the local board

• Secure using thumbscrews

The MASSO Touch side is now complete.
 

Close the cabinet.

Machine Side

Step 1

Install the 2 optocoupler ICs into the machine-side module

Step 2

Install the screw terminal plugs removed earlier into the machine-side board

Step 3

• Connect both 37-pin cables

• One connector is male and the other is female, so they will only fit correctly

• Secure using thumbscrews

Step 4

Attach the MASSO G3 cover using the 4 screws

Pull Up Resistors

• Use the onboard switches to enable pull-up resistors

• No external wiring is required

• Turn on the switch for the required input
