3.6.3 Control Unit
3.6.3.1 Instructions for Working with Control Units
CAUTION
Observe the ESD regulations!
When handling control unit assemblies, observe the ESD regulations for your own safety and the
safety of the machine:
➢ When removing or installing individual assemblies, always wear the ESD wristband, to prevent
damage to the electronics system.
➢
Also observe the ESD regulations specified in the SIPLACE SX1/SX2 user manual.
3.6.3.2 Replace the Power Supply Board [03071546-xx]
Spare Part
• WPC power supply board [03071546-xx]
Removal / Installation
➢ Wear the ESD wristband.
➢ Open the top and bottom locks and loosen the 4 screws fastening the front plate of the
power supply board.
➢ Carefully pull the power supply board (see "3.6.3 Control Unit" [➙ 3-48]) out of the control
unit.
➢ Carefully insert the new power supply board.
➢ Make sure that the power supply board engages properly.
➢
Tighten the 4 screws fastening the front plate of the power supply board and lock the top
and bottom locks.
Settings
• No settings are required.
NOTICE
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.
Use a digital multimeter to measure the voltages at the respective pins on the front plate
of the power supply board.
