2-8 Safety

2.10.1 Emergency Shutdown Situations

As a minimum, activate the EMO in the following situations:

 If anyone is in immediate danger of being injured by moving parts, hazardous materials,

or electrical shock.

 If valuable AXI system components or the workpieces are in danger of being damaged.

2.10.2 Emergency Shutdown Recovery

WARNING! Do not restart the AXI operation until the condition that caused the emergency

shutdown has been corrected. Failure to comply could cause serious injury to the

user and/or serious damage to the AXI system.

To recover after an Emergency Shutdown:

1. Locate and remedy the cause of the emergency shutdown. If necessary, refer to

Section 28 - Trouble Shooting.

2. If applicable, close the AXI area doors.

3. Turn the EMO knob clockwise until it pops back into position.

4. Restart the YesAX Software program. See 3.8 Power On for details.

2.10.3 Electromechanical Interlocks

Electromechanical interlocks prevent personnel from being exposed to high voltages, x-rays, and

mechanical hazards that are present while the AXI system is in operation.

The front door of the AXI system has two interlock switches. When the door is closed the conveyor and

stages can move and the x-ray can emit. When the door is opened the conveyor and x-y stages cease

movement and the x-rays stop emitting.

The chute doors for board loading and unloading have a switch and a sensor. The switch is a CDRH rated

dual interlock switch. X-rays can emit when the chute doors are closed. The X-rays stop emitting when a

chute door opens. In addition, the chute doors use a laser sensor. The sensor prevents the door from

shutting when an obstacle is present within the opening.

WARNING! When these interlocks are activated, the electrical power remains ON.

In order to resume operation, all access points must be closed and the interlocks must be reset using the

touch screen.

Safety 2-9

2.11 Service Shutdown

Companies may differ in their Lockout/Tagout (LOTO) procedures and requirements, and it is the

responsibility of the end user to determine compliance with local safety procedures. The purpose of any

LOTO effort is to help avoid injury or AXI system damage due to unexpected energizing of equipment,

start up, or the release of stored energy during repair, maintenance, and operation of equipment.

Situations where LOTO practices may be employed on your AXI include:

 Adjusting cables, belts, pulleys, or moving parts

 Servicing bearings or motors

 Troubleshooting, servicing, or replacing electronic components or assemblies

 Troubleshooting, servicing, or replacing pneumatic components or assemblies

Situations where LOTO practices might not be required are when troubleshooting electrical, pneumatic,

or hydraulic components or assemblies that make de-energizing the whole system impractical.

Troubleshooting or servicing you AXI system while powered up and operating should only be

accomplished by fully trained and qualified personnel. There should always be a second person present

when performing maintenance on a system under power.

WARNING! All personnel working on or near the AXI system should know the location of all

electrical power supply sources.

WARNING! CAUTION!

Lock out and tag out electrical power before performing service or maintenance

work on the AXI system. Failure to do so could cause serious injury to the user

and/or serious damage to the cure module.

2-10 Safety

To lockout/tagout the electrical and pneumatic energy:

1. Shut down the computer.

2. Press the red EMO button (Figure 2-4) to turn OFF the system.

3. Turn the Power switch to the OFF (O) position.

4. Disconnect the electrical plug from the facility power outlet.

5. Attach a prominent warning tag to the power cord with durable string.

 This tag documents the name of the technician taking the equipment out of operation,

the date, and other facility-required information. It is a warning that the equipment

cannot be put back into operation until the authorized technician has removed the tag.

6. Perform maintenance, servicing, and troubleshooting as necessary.

 NOTE Warning tags document the name of the technician taking the equipment out of operation,

the date, and other facility-required information. It is a warning that the equipment cannot be

put back into operation until the authorized technician has removed the tag.
