Safety Systems

The PSV2800 System has several safety systems to prevent personal injury and equipment damage, including emergency stop (E-Stop) buttons and safety doors.

Emergency Stop (E-Stop) Buttons

Two large, red Emergency Stop buttons are located near the top of the PSV2800 System— one on the right side near the front, and one on the right side near the back of the machine. When an E-Stop button is pressed, the gantry stops moving immediately.

Caution note Caution

Shock hazard! Pressing an E-Stop button removes power from the motion controller (gantry) only. It does NOT remove electrical power from the PSV2800 or any optional equipment installed. Turn the main power OFF before opening any access doors.

Caution note Caution

Pinch hazard! The E-Stop does not shut off air. Socket actuators can still move down and up.

Safety Doors and Interlocks

Designed to protect against injury and damage from the PNP head movement, the safety doors are an important safety feature, stopping the gantry when they are opened.

During operation, when the high-speed PNP head is processing devices, the clear plastic safety doors around the workspace are closed to protect operators from injury. Each safety door has a safety interlock which stops gantry movement if the operator forgets to first park the PNP head.

Prior to opening a safety door
Normally, if the power is ON, before opening any safety door:

  • at the Run window, ensure the job is Paused or Finished (stopped), or

  • at the Gantry window, the PNP head should be sent to the park or tool position (by clicking Park or Tool), or

  • at the Setup window, any time before a job is started.

Caution note Caution

Possible collision hazard! The high speed and force of the gantry can seriously harm anyone working inside the workspace.

When working in the machine workspace, moving the PNP head must be the responsibility of only one qualified individual. All others must stay clear of the machine controls to prevent injury to that person. Never bypass or otherwise render safety interlocks inoperable.

Caution note Caution

Shock hazard! Opening safety doors stops motion of the gantry only. It does NOT remove electrical power from the machine or any optional equipment. Turn the main power OFF unless otherwise directed.

Caution note Caution

Possible product damage! Do not use solvents such as acetone, lacquer thinner, mineral spirits, isopropyl alcohol, or any type of abrasive compound on safety doors. These products damage the safety door surfaces and ESD coating, and reduce visibility of the work area.

Electrostatic Discharge

Devices (integrated circuits) are very sensitive to static, and could be damaged by unintended electrostatic discharge while being handled. So ensure a common electric potential (ground) exists between a static-sensitive device or component, its environment, and the operator.

Operators should wear an antistatic wrist strap (Data I/O part number 440-0021-001) connected to a grounding connection on the machine. The wrist strap should contain a 1–10 M-ohm current limiting resistor.

When Operators plug an antistatic wrist strap into the ESD strap connection on the PSV2800, it reduces the risk of damage to devices and Socket Adapters from electrostatic discharge.

Handling Devices Safely
To prevent damage to device pins, use a vacuum tool/tweezer to pick up devices (the tool handles devices without damaging them).

Caution note Caution

Possible device pin damage! Do not touch devices with your hands or any implement other than the vacuum tool. Doing so can damage devices with fine-pitched leads.

Vacuum tools use a squeezable air bladder for suction. There are a variety of models, sizes and tips. Some tips are replaceable.
