24V LED - Work Light - 200W LVPS - Replacement

Introduction

This procedure will show you how to replace the Low-Volt Power Supply (LVPS) for the Work Light or Table Work Light (If equipped).

This Document Applies to the following Service Kits:

93-3521 VF-M WRITING TABLE 200W PS RETROFIT KIT

Note: Do NOT send back the old 100W power supply once it is replaced.

Electrical Safety

DANGER: Working with the electrical services required for CNC machines is extremely hazardous and can result in serious injury or death.

Before connecting line wires to the CNC:

Turn off all power to the machine at the source.
Perform a Lockout-Tagout (LOTO) procedure to ensure the power remains off during service.
Verify that power has been disconnected by using an AC voltage detector on all incoming lines.

If you are uncertain about how to safely disconnect power or perform LOTO procedures:

Do not proceed.
Contact qualified personnel or obtain appropriate assistance before continuing.

Failure to follow these precautions may result in electrical shock, equipment damage, or fatal injury.

Danger: Before beginning any work inside the control cabinet, verify that the High Voltage indicator light on the 320V Power Supply / Vector Drive has been off for a minimum of five (5) minutes. This waiting period ensures that residual voltage has dissipated and reduces the risk of electric shock.

Certain service procedures involve high-risk electrical components and may pose serious injury or fatality hazards. Technicians must not attempt any procedure unless they have a complete understanding of the steps involved and the associated risks.

If there is any uncertainty regarding a procedure, contact your Haas Factory Outlet (HFO) to arrange for a qualified service technician.

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

2

Locate the 24V Work Light LVPS [1] next to the left panel.

Disconnect the wires [2] going to the LVPS terminal strip.

NOTE: Before disconecting the wires note the location of the wires attached to the LVPS terminal strip.

Remove the screws [5] securing the LVPS [6] to the plate [4].

Remove the screws [3] securing the plate [4] to the enclosure.

3

On the side of the power supply there is a voltage input switch. Set the voltage input switch to 115V [1].

4

Install the new 200W LVPS [1] to the plate [2] using the 4 screws.

Then, install the plate [2] to the enclosure [3] using the 4 screws.

Reconnect the wires [4] to the LVPS terminal strip.

NOTE: Make sure the labels on the spade connectors match the terminal strip label.

5

Turn on the Machine.

Actuate the light switch on the side of the controller to test that the work and table light turn on.
