Strip Chart Recorder Servicing: Removing the Strip Chart Recorder
Removing the Strip Chart Recorder
Removing the strip chart recorder requires loosening the monitor’s front panel bezel.
Following this procedure carefully will avoid unnecessary damage to bezel’s
mounting screws and the unit’s front panel connectors.
1. Turn off the 120 Series Monitor and disconnect the power cord from the
monitor.
2. Remove the nine screws which secure the monitor top cover. Four screws are
located on the bottom of the monitor and five screws are located in the back.
3. Remove the cover by sliding it toward the rear of the monitor.
4. Remove the copper grounding strips from the top of the front bezel to prevent
damage when removing the recorder.
5. Remove the two screws on the bottom of the monitor which fasten the strip
chart recorder.
6. Remove the two screws which fasten the right side of the front bezel to the
monitor. Loosen the two at the left just enough to pull the right side of the bezel
away from the chassis.
7. Disconnect the display ribbon cable from the DSP Board at J5.
8. Disconnect the ribbon cable from the membrane switch panel. Leave the other
end connected to the DSP Board.
9. Disconnect the ribbon cable from the Recorder Board at J2. Leave the other
end connected to the Main Motherboard.
10. Disconnect the Power Supply cable harness from the Recorder Board at J1.

front bezel.

recorder out.
