Searchline Excel

2104M0506

The Searchline Excel Open-Path Gas Detector requires little maintenance other than occasional
cleaning.

Depending on the local regulations and site conditions, cleaning and functional testing of the
gas detector can be carried as described in the following sub-sections. The gas detector should
remain powered during these procedures.

Caution: searchline excel does not contain any user serviceable parts. do not open

either the transmitter or receiver unit. the warranty of units which have been
opened is invalidated.

Note:

the iNfrared beam is iNvisible aNd eye safe.

4.1 INSPECTION AND CLEANING

Caution: do not use solvents or abrasives on the searchline excel units.

(1)

Inspect the Searchline Excel units, junction box and cabling for signs of physical
damage.

(2)

Using the SHC1 Handheld Interrogator inhibit the Searchline Excel signal output.

Since the signal output may vary during cleaning, due to the optical path being disturbed,

it is important to inhibit the analogue output. The quickest way to inhibit the Excel output

is to select

DISPLAY from the Calibration menu.

(3)

Clean any dust or dirt from the Searchline Excel windows using soapy water and a soft
cloth.

(4)

Using the SHC1 Handheld Interrogator release the Searchline Excel signal output.

The output can be released by pressing

esC

followed by on the keyboard.

(5)

Using the SHC1 Handheld Interrogator re-zero the unit.

See Appendix A

for details about how to use the Interrogator.

4.2 FUNCTIONAL TESTING (Plastic Test Filters)

From January 2004 onwards, a new range of plastic test filters has been available for performing

functional testing on Searchline Excel. They are lettered from A to H, with the reading a filter

produces increasing in alphabetical order.

Whilst the new filters can be used with all Mod states of Searchline Excel units, they have been

specifically designed to work with open path Excel units of Mod state 7 (or higher).

The part number for the new test filter set is 2104N2999.

Testing of Mod state 6 (or lower) open path Excel units should continue to be performed using

the original plastic test filters, with the results to be anticipated detailed in Issue 8/9 of the

Technical Handbook, 2104M0506.

For information on testing Mod state 6 (or lower) Excel units refer to addendum 2104M0523
available from [email protected].
