To remove the old SmartPAC 2 PC board and install the new replacement board, perform the
following steps:
1. Shut off power to the SmartPAC 2.
2. Open the SmartPAC 2 enclosure or console.
3. Making sure you are grounded, unplug all wired connectors from the SmartPAC 2 PC
board (see Figure E-1, page E-3), including connectors on the ProCamPAC and DiProPAC
boards (if installed).
4. Remove the DiProPAC and ProCamPAC PC boards, if installed, and set them aside in a
safe location.
5. With a ¼-in. nut driver, remove all six ¼-in. nuts and six of the eight ¼-in. standoffs (see
Figure E-1). Do not remove the upper right standoff for the ProCamPAC PC board or the
lower left standoff for the DiProPAC PC board.
ELECTRIC SHOCK HAZARD
• Ensure that the power source is off before you replace electronic components in a
control.
• Disconnect power from the machinery it is connected to before replacing electronic
components. This includes disconnecting power to the machine control and motor.
• Ensure that servicing is performed by qualified personnel.
Failure to comply with these instructions could result in death or serious injury.
DAMAGE TO BOARD FROM STATIC DISCHARGE
Ground yourself before touching circuit boards or chips by touching a large metal object
such as the press. Static electricity can destroy electronic components.
Failure to comply with these instructions could result in property damage.
Connectors are labeled “TBnnn” or “Jnnn” in Figure E-1, where nnn is a three-digit
numeric identifier.
To remove the small display connector J115, grasp the connector firmly between your
index finger and thumb and wiggle it gently back and forth in an upward direction. Do not
pull on the wires attached to the connector.
Do not remove the SOM (Industrial Computer) circuit board (see Figure E-1).
