SST-2000A/H的安裝
裝置的安裝
使用標(biāo)準(zhǔn)手工具安裝SST-2000A-/H;一般使用標(biāo)準(zhǔn)操作安裝在控制面板或密封裝置上。

信號(hào)輸入(低端,末端6) 對(duì)輔助生產(chǎn)(低端,末端7)通用,通常使用在直流電源(末端4)和低端(末端9)主要的比例輸出裝置上。 繼電器觸點(diǎn)常常需要進(jìn)行分隔;
當(dāng)使用交流電源:所以的電路必須與內(nèi)置供應(yīng)變壓器和電源線隔離;
當(dāng)使用直流電源:變送器輸出不與直流電源隔離;任何變送器驅(qū)動(dòng)的負(fù)荷(即記錄器,,控制器,等)必須有如直流電源陰極的相同。 如果負(fù)荷不引用SST-2000相同的通用標(biāo)準(zhǔn),安裝在4-20ma輸出電流和負(fù)荷電流環(huán)路隔離裝置。

Mounting the unit
The SST-2000A/H is installed using standard hand tools. It is generally mounted in a panel or enclosure using standard practices.
About Electrical Connections
Internal Commons, Isolation
WARNING: AVOID DAMAGE WHEN DC-POWERED
Install a current loop isolator between the 4-20 ma output and the load if the load does not reference the same common as the SST-2000A/H.
Signal input (low side, terminal 6) is common to the auxiliary output (low side, terminal 7), to the dc supply (terminal 4), and to the main proportional output low side (terminal 9). Relay contacts are always isolated
When powered with ac: all circuitry is isolated from the power line by the built-in supply transformer
When powered with dc: the transmitter output is not isolated from the dc power source. Any load driven by the transmitter (i.e. recorder, controller, etc.) must have the same common as the negative side of the dc supply. Install a current loop isolator between the 4-20 mA output and the load if the load does not reference the same common as the SST-2000.
Fig. 2-1 Electrical Connection Drawing.
Use shielded cable: connect ungrounded shield to terminal 4.
Route power line and relay connections separate from signal meter and reset lines to prevent electrical noise interference.
Terminals 4, 6, 7, and 9 are internally tied together to circuit common unless unit has signal isolation transformer. In that case, terminal 6 is isolated. ® 0 ® ®
