在接線盒和張力電子設(shè)備之間，必須路由信號和勵磁在單獨的電纜中。例如：用于勵磁和屏蔽的2×2.5 mm2電纜4×2×0.5 mm2電纜，雙絞線芯，用于稱重傳感器信號。?兩個更高張力電子設(shè)備IP-20版本的同步電纜（未密封）必須是屏蔽或雙絞線。?張力電子設(shè)備和儀表或工藝設(shè)備之間的信號電纜，必須為屏蔽0.5 mm2電纜。?電纜屏蔽必須連接到銅接地棒。
IS200TBCIH1CCD燃機模塊屏幕連接最大值長度為50 mm。?輸入電源的保護(hù)接地導(dǎo)體必須連接到機柜中的銅接地棒IP-65版本（NEMA 4）。干擾為了抗干擾，稱重傳感器電纜應(yīng)盡可能與電源電纜噪音大。建議最小距離為0.3米（12英寸）。哪里測量系統(tǒng)電纜遇到嘈雜的電纜，它們必須以直角交叉。2.4.1.3同步壁掛式IP 65版本（NEMA 4）張力傳感器不需要同步電子學(xué)如果兩個或多個IP 20版本（未密封）張力電子設(shè)備安裝在同一機柜中它們必須同步。通過互連所有的“同步”端子（螺釘端子X3:15）來實現(xiàn)同步所有裝置的裝置和互連螺釘端子X3:16。雙絞線電纜或必須使用屏蔽電纜。如果一個裝置關(guān)閉或拆除，其余裝置仍保持同步。Between the junction box and the tension electronics, signal and excitation must be routed
in separate cables. For example: a 2 × 2.5 mm2 cable for the excitation and a shielded
4 × 2 × 0.5 mm2 cable with twisted pair cores for the load cell signals.
? Cable for synchronization of two of more tension electronics IP-20 version (unsealed)
must be screened or a twisted pair.
? The signal cable between the tension electronics and instruments, or process equipment,
must be a screened 0.5 mm2 cable.
? Cable screens must be connected to the copper earth bar. The screen connection maximum
length is 50 mm.
? The protective earth conductor of the incoming mains supply must be connected to the
copper earth bar in the cabinet IP-65 version (NEMA 4).Interference
For immunity to interference, the load cell cables should be separated as far as possible from
noisy power supply cables. A minimum distance of 0.3 m (12 inches) is recommended. Where
the measuring system cables meet noisy cables, they must cross at right angles.
2.4.1.3 Synchronization
Synchronization is not required for the wall mounted IP 65-version (NEMA 4) of the tension
electronics.
If two or more IP 20-version (unsealed) tension electronics are mounted in the same cabinet
they must be synchronized.
Synchronization is done by interconnecting the “SYNC” terminals, screw terminal X3:15, of all
the units and interconnecting screw terminal X3:16 of all units. A twisted pair cable or a
screened cable must be used.
If one unit is turned off or removed the remaining units are still synchronized.
