Oil in Water Part III

The reference voltage is checked by the ADC every ten minutes.

This indicates one or more of the following potential failure conditions:

1.The lamp has failed.

2.The cell windows have become so dirty that no light can pass through the sample.

3.The sample is opaque, due to the presence of solids or undesirable optical phenomena in the sample.

4.Condensation has occurred on the cell windows.

5.The signal processing electronics, phototube, signal cable, or demodu- lator switch has failed.

6.The filter wheel is loose on the motor shaft.

7.The reference optical filter is dirty or defective.

8.The optical bench or lamp is out of alignment.

4.0INSTALLATION

The oil-in-water system must be installed in an area where the ambient temperature is not permitted to drop below 32oC or rise above 122oF

(50oC),(for salt water applications, the freezing point is lower due to the salt content). Cubicle installed systems (Models 6600), subject to the preceding conditions, may be installed outdoors. Rack-supported systems must be completely sheltered from the elements.

Note: Ambient temperatures below 0oC, requires heated enclosures.

Rack-supported systems must be installed in a well-ventilated area to prevent the surrounding atmosphere from becoming saturated with the moisture being generated by the sample preconditioning processes of the system.

Only in one case when the sample system uses gravity flow should the system be installed on a level surface otherwise all other systems ar5e to be with sufficient space allocated on either side (6 feet minimum) for person- nel and test equipment access. Subject to the foregoing, the system should be placed as close to the sample point as possible and bolted to its supporting
