励磁电路中允许的大电缆电阻如表2-1所示。
调试前，检查称重传感器励磁电路中的电缆电阻。
•实心导线不应连接到端子。引脚不应压接至
绞合芯。
•称重传感器的电缆必须是坚固的四芯电缆，见图2-2。
信号电路和励磁电路必须使用对角线对。
图2-2.称重传感器电缆中的芯线布置
•接线盒和张力电子设备之间，信号和激励必须布线
在单独的电缆中。例如：用于励磁的2×2.5 mm2电缆和屏蔽电缆
用于称重传感器信号的4×2×0.5 mm2双绞线芯电缆。
•两个或多个张力电子设备IP-20版同步电缆（未密封）
必须屏蔽或双绞线。
•张力电子设备和仪器或工艺设备之间的信号电缆，
必须是屏蔽0.5 mm2电缆。
•电缆屏蔽必须连接到铜接地棒。屏幕连接大值
长度为50mm。

2.4.1.2干扰
为了抗干扰，称重传感器电缆应尽可能远离
嘈杂的电源电缆。建议小距离为0.3米（12英寸）。哪里
测量系统电缆遇到噪声电缆时，它们必须以直角交叉。
2.4.1.3同步
壁挂式IP 65版本（NEMA 4）张力无需同步
电子学
如果两个或多个IP 20版本（未密封）张力电子设备安装在同一机柜中
它们必须同步。
通过互连“同步”端子，螺钉端子X3:15，实现同步
所有装置的装置和互连螺钉端子X3:16。双绞线电缆或
必须使用屏蔽电缆。
如果一个单元被关闭或移除，其余单元仍保持同步。

The maximum permitted cable resistance in the excitation circuit is shown in Table 2-1.
Before commissioning, check cable resistance in the load cell excitation circuit.
• Solid conductors should not be connected to terminals. Pins should not be crimped to
stranded cores.
• The cable from the load cell must be a robust four core cable, see Figure 2-2.
Diagonal pairs must be used for the signal circuits and excitation circuit.
Figure 2-2. Core Arrangement in Load Cell Cable
• 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).

2.4.1.2 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.

The electronic unit is delivered in an enclosure intended for wall mounting.
When choosing a place for installation, make sure that there is enough space to open the
enclosure lid fully. Also check that there is enough working space in front of the enclosure.
The enclosure is fitted with 13 cable glands.
Figure 2-4. Installation Dimensions
Connect the cables to terminals according cable diagrams in Appendix (B, C, D, E, F or G)
depending on installed load cell type.
NOTE
Do not connect solid conductors to terminals. Do not crimp pins to stranded
cores.
NOTE
The incoming mains voltage must be provided with fuses and a means of
disconnection outside the tension electronics
