Teledyne 6600 manual Installation Check, Electronics Check

Part III Model 6600

The system safe vent should be equipped to accept a 1-1/2” drain pipe. Also, the diameter of the drain should be large enough to carry away the full capacity of the incoming 1/2” sample line. The system safe vent should be vented to atmosphere at the panel, but the user’s system will have to include a trap and or scrubber (if H2S present, etc.) if the effluent is to be discharged into a sewage system. It must be remembered that the vent to be is at floor level; flooding of the installation area will result in the event of stoppages, or when drain levels are not below the system vent connector. Also, note this vent is used to accept the auto-zero backflashing of the sample and as such high release pressure, liquid and/or gas velocities will be encountered. Never obstruct this vent by any human personnel means to eliminate any injuries.

5.0SYSTEM START-UP/CALIBRATION

The information contained in the following subsections deals primarily with the steps necessary before the total system can be used for continuously monitoring oil in water. This information involves installation checks, electrical checks, fluid dynamics, and calibration.

Due to variations in water and oils as encountered under field conditions, certain adjustments must be made to optimize system performance for the specific site. This includes calibration.

5.1Installation Check

1.Observe that power, signal and alarm connections are properly made and that the system is properly grounded. Refer to Installation Section of manual and to Outline and Interconnection Drawings.

2.Inspect the external sample delivery system, including sample pump (when applicable), sample take up point, and source of water sample.

3.Confirm that the recorder is of the correct type.

5.2Electronics Check

1.Check that all PC boards are in place.

2.Turn off ultrasonic homogenizer by rotating the homogenizer potenti- ometer fully counter-clockwise (OFF). Refer to calibration section 5.6.5 for final adjustment.

3.Switch on electronics and confirm that 15 volt, and -230 volt, 10 volt is present.

4.With an oscilloscope, check test points and reed switch action with air or oil-free water in the cell.
