(*.MA
). See Section 4.3.2 Saving
the Machine Data [J66].
X Wear the ESD wristband.
X Unplug the CAN bus cable from the front of the controller board.
X Loosen the 2 screws fastening the front plate of the controller board.
X Carefully pull the controller board (see Section 3.5.1 Control Unit [J29]) out of the control unit.

Settings
X Perform a firmware download (BIOS and application) for the controller board.
To do this, open the SITEST main view and select the function=>
Download
=> tab
WPC
. For
further information, refer to the SITEST manual for placement machines.
X Restore the
*.MA data
for which you made a backup copy. See Section 4.3.3 Restoring Machine
Data [J66].
NOTE: Check the power supply board voltages.
The green LEDs on the power supply board only show whether voltage is present or not
(function monitoring). They do not show whether this voltage is correct.
X Use a digital multimeter to measure the voltages at the respective pins on the front plate of
the power supply board.
NOTE: Backup battery
A backup battery is located on the controller board.
X Replace this battery if you are shown the error message "17802 WPC: Voltage of back-up
battery is too low“.
NOTE: Calibration
If you are able to restore a current MA file, you do not need to recalibrate the WPC4.
If you are unable to restore a current MA file, you will need to recalibrate the WPC4.
