1.4 Profibus Card Installation Instructions
Use the following instructions to install the Profibus Communications Option into an existing Q46
Analyzer. NOTE: An existing analyzer MUST have the cutout on the side of the enclosure to
use this set of instructions. If you DO NOT have the correct rear enclosure, and would like to
utilize this communication option, please consult the factory for the correct part numbers needed
to use Profibus.
1. Remove the connector cover on the side of the enclosure, by removing the hardware holding the
cover in place, and discard.
2. Remove the jack screws from the front of the DB9 connector, and put them aside.
3. Loosen the screws holding the power supply board.
4. Install Profibus PCB first by passing connector into hole in side of enclosure, and then adjusting
position of board over the power supply label board until rear header smoothly presses into
place. It is necessary to move the Power Supply w/cover to the right of the enclosure while
adjusting (with the other hand), and to pull front of DB9 connector high while the rest of the
board is low. It helps to line up mounting hole so you can feel where the lower connector is
located. Press Profibus board rear edge down firmly once in place.
5. Outside of the enclosure, line up the DB9 holes on the enclosure with the holes in the
connector. Using a 3/16” nut driver, install the two jack screws through the enclosure and into the
DB9 connector. DO NOT OVERTIGHTEN, but make sure they are very snug Overtightening too
much can make them bend out by distorting the plastic case, and they wont connect to the
Profibus interface cable. After you have the screws snug, observe the gasket on the PCB inside
the enclosure, and make sure it is making a tight seal. If not tighten the jack screws a little more
until one is observed.
6. Place the label board over the Profibus board and line up the mounting holes.
7. Install the ¾” screw into the hole next in the PCB next to the marking” Profibus DP”.
8. Install the 1-1/8” lg screw into the remaining hole in the cover and secure both.
9. Retighten the screws holding the Power Supply board in the enclosure.
