Main Control PCB Replacement

1

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

Danger: After turning off the machine, wait at least 5 minutes before working in the control cabinet, to allow power todissipate. Wait for the voltage indicator LED on the vector drive to go off completely.

Caution: When you touch a PCB, you must put on an Electrostatic Discharge (ESD) strap.

2

 Note: The Main Control PCB leaves the factory without a battery, refer to the Main Control PCB - (Coin Type) - NGC - Battery Replacement/Install procedure for what type of battery to install and how to do so properly.

Disconnect all of the cables from the Main Control PCB.

 Note: Put an identification label on each cable that is attached to the PCB. This makes the installation easier.

Remove the used Main Control PCB.

Install the new Main Control PCB. 

NOTE: If the PCB you are replacing has a plastic enclosure, refer to the Main Control Enclosed PCB section below.

Connect the cables. Use your identification labels to make the connection

Main Control Non Enclosed to Main Control Enclosed PCB Replacement

Use the following procedure below to replace a non-enclosed Main Control PCB to an Enclosed Main ControlPCB.

1

Once the steps from the previous section for removing the Unenclosed Main Control Board are complete, proceed with the following steps to install the Main Control Enclosed PCB.

Remove the male-to-male end standoffs from the chassis of the control cabinet, where the Unenclosed Main Control Board was previously mounted.

Install the four 6-32 male to female stand offs used to mount the Enclosed Main Control Board. 

Install the three threaded rods to the following standoffs shown [1].

Note: [2] Will be the only stand off without a threaded rod. 

2

IMPORTANT: Make sure all cables are labeled so that they can be plugged into the new PCB.

Mount the new Main Control Enclosed PCB by aligning it on the threaded rods [1]. 

Once aligned, fasten the center Philip's Pan Head Screw (PPHS) [2] to fix the PCB in position.

3

Fasten the 4 standoffs [1] to the threaded rods that aligned the PCB.

Route the ground cable and fasten it to the Control Cabinet Chassis [2].

NOTE: The image shows one possible location to mount the ground cable to the chassis. The cable can be mounted to any available location on the chassis.

Once mounted make sure that all the cables are plugged into the PCB according to the labels used in the previous step.

Follow the BTD Replacement to continue with mounting the Broken Tool Detection PCB install if applicable to the machine.

Load Software

Note: This process can only be done by a certified Haas technician, 

You must do a "clean" software install when you replace the Main Control PCB. Refer to Software Update - (Option 5) Clean Installation - NGC.

Memory Upgrade Activation

The 32GB or 64GB memory upgrade kits need an activation code to enable the memory on the control.  Refer to NGC configuration 24.1120 and Later.
