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 X1:14, of all
the units and interconnecting screw terminal X:15 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.
