燃燒器板上的孔，并使用三個(gè)六角帶帽螺釘（未提供）固定。安裝瞄準(zhǔn)具旋轉(zhuǎn)底座上的管道。如果未使用旋轉(zhuǎn)接頭，將觀察管末端插入孔中，
將孔對準(zhǔn)所需的觀察角度并點(diǎn)焊（焊接必須足以支撐所安裝掃描儀的重量）。觀察管應(yīng)傾斜布置向下，這樣灰塵和污垢就不會聚集在里面。當(dāng)通過運(yùn)行測試確認(rèn)觀測結(jié)果令人滿意時(shí)，固定轉(zhuǎn)環(huán)通過擰緊位于旋轉(zhuǎn)接頭上的三個(gè)六角頭螺釘，將支座的球定位到位安裝環(huán)。
8、為了便于使用，掃描儀應(yīng)安裝在觀察管上，以便LED顯示屏可以輕松顯示被閱讀。
DS215SLCCG1AZZ01A電氣卡件注：LED顯示屏的操作與位置無關(guān)。掃描儀透鏡和掃描儀外殼必須無污染物（油、灰、煙塵、污垢）
溫度不得超過其最大額定值150°F（65°C）。溫度過高會縮短掃描儀壽命。通過在以下位置連續(xù)噴射凈化空氣，可滿足這兩項(xiàng)要求
3/8“殼體入口或旋轉(zhuǎn)底座前的1”Y“接頭，如所示圖5：。
掃描器的安裝可以只通過3/8英寸的開口吹掃空氣，或者通過3/8“開口或1”Y“接頭凈化空氣。在后一種安排中，通常
兩個(gè)接頭中只有一個(gè)配有凈化空氣，另一個(gè)接頭堵塞。使用密封聯(lián)軸器，1“Y”接頭用于凈化空氣，3/8”開口堵塞。
在所有裝置上使用密封聯(lián)軸器（P/N 60-1199-x，帶NPT螺紋）是一種良好的做法確保不必要的爐壓不會損壞掃描儀鏡頭。
DS215SLCCG1AZZ01A電氣卡件在正常條件下，使用清潔燃燒的燃油和中等環(huán)境溫度條件，吹掃大約4 SCFM（113 l/min）的空氣流量通常足夠。高達(dá)15 SCFM（425升/分鐘）可能需要用于產(chǎn)生高水平灰分或煙塵的燃料，或用于高溫環(huán)境將掃描儀的內(nèi)部溫度保持在規(guī)定范圍內(nèi)。
When a satisfactory sighting has been confirmed by operational testing, secure the swivel
mount’s ball position in place by tightening the three hex head cap screws located on the swivel
mount ring.
8.
For ease of use, the scanner should be installed on the sight pipe so the LED display can easily
be read.
Note: Operation of the LED display is independent of position.
9. The scanner lens must be kept free of contaminants (oil, ash, soot, dirt) and the scanner housing
temperature must not exceed its maximum rating of 150° F (65° C). Excessive temperatures will
shorten scanner life. Both requirements will be satisfied by a continuous injection of purge air at
either the 3/8" housing inlet or the 1" “Y” connection ahead of the swivel mount as shown in
Figure 5.
The scanner mounting may be made with provision for purge air through only the 3/8" opening or for
purge air through either the 3/8" opening or the 1" “Y” connection. In the latter arrangements, normally
only one of the two connections is provided with purge air and the other connection is plugged. When a
sealing coupling is used, the 1" “Y” connection is used for the purge air and the 3/8" opening is plugged.
It is good practice to use the sealing coupling (P/N 60-1199-x with NPT threads) on all installations to
insure against unwanted furnace pressures from damaging the scanner lens.
Under normal conditions, with clean burning fuels and moderate ambient temperature conditions, purge
air flow of approximately 4 SCFM (113 l/min) is generally adequate. Up to 15 SCFM
(425 l/min) may be required for fuels that produce high levels of ash or soot, or for hot environments to
maintain the scanner’s internal temperature within specification.
