1 Printed Circuit Board Replacement for Sievers Model PPT TOC Analyzer 1. Purpose 2. Scope Replace printed circuit boards (PCB s) in the Sievers Model PPT TOC analyzer. This procedure describes how to replace power control, CPU and analog PCB s in the Sievers Model PPT TOC Analyzers. 3. Responsibilities Properly trained personnel are responsible for the documentation and performance of this procedure. Personnel must have thoroughly read the Operation and Maintenance Manual. Personnel performing this procedure must have been trained and demonstrated performance operating the analyzer prior to performing this procedure. 4. Safety This procedure requires access to the inside of the analyzer. To avoid potentially dangerous shock, unplug the analyzer before opening the analyzer s door. Follow normal ESD precautions when handling electronic components. 5. Materials 5.1 Replacement Printed Circuit Board(s). Referred to hereafter as PCB(s). 5.2 ESD Wrist Strap CAUTION: These printed circuit boards contain ESD sensitive components. Prior to performing the following instructions, it is essential to be grounded according to established procedures. Failure to be properly grounded will result in ESD damage to the boards and void the warranty. GE Analytical Instruments, Inc. 2005H Page 1 of 13 DIN Rev. A

2 6. Procedure 6060 Spine Road CAUTION: Prior to performing the following instructions it is essential to be grounded according to established procedures. Failure to be properly grounded will result in damage to the boards and void the warranty. 6.1 Disconnect all power to the analyzer before removing any PCB. WARNING: The wall plug of the AC power cord is the mains disconnect device for the PPT. High voltage is present in the analyzer when power is connected. The door switch automatically turns off the analyzer when the door is open, minimizing the risk of shock; however, the switch can be overridden by pulling it out or pushing it in. In addition, the power connection and electronics before the switch are still powered. To eliminate all risk of shock, you must disconnect the power to the analyzer before working inside the analyzer. The power cord should only be detached from the analyzer AFTER disconnecting the mains plug from the AC wall outlet. WARNUNG: Das Netzkabel ist die einzige Möglichkeit das PPT Meßgerät vollständig von der Spannungsversorgung zu trennen. Bei verbundenem Netzkabel liegt Hochspannung am System an. Zwecks Personenschutz setzt ein interner Türschalter das Gerät beim Öffnen der Fronttür automatisch spannungsfrei. Allerdings bleiben die Spannungszuführung und die Stomkreise vor dem Schalter spannungsführend. Der Schalter kann durch Herausziehen überbrückt werden (auf eigene Gefahr). Um allen Personenschäden vorzubeugen ist vor Arbeiten im Geräteinnern die Spannungszufuhr zum Gerät zu unterbrechen. 6.2 Follow the instructions in the sections listed below to replace the necessary PCBs Power Control Board Section Central Processing Unit Board Section Analog Board Section 6.5.

5 NOTE: The cables and the boards are labeled with either a J or P and then a matching number. Sometimes the board connection is labeled with a J, sometimes a P. The same situation occurs with the cables. This procedure will provide both the cable letter/number and the board letter/number. NOTE: Throughout this procedure there will be insets of Figure One. These insets will provide direction for connecting or disconnecting electrical and plumbing components. Figure 3: Label on Card Cage Cover GE Analytical Instruments, Inc. 2005H Page 5 of 13 DIN Rev.
