4.3 The technical requirements for wire arrangement of peripheral equipments of the
elevator integrated drive controller.
4.3.1 The cable requirement of hoist way and accompanying cable arrangement
Fig 4.2 hoist way and accompanying cable arrangement
Both elevator shaft and trailing cable each has four communication cables (TXV+、TXV-、TXA+、
TXA-) .
◇ Cares should be taken to avoid shorting between these four cables (TXV+、TXV-、TXA+、
TXA-) and other cables. Prior to switching on, universal meter must be used to check there is
no any loop between these four cables and other cables, especially such as 24V, 36V, 110V,
220V, 380V and other supply cables.
◇ Cable TXV+ and TXV- supplies to branch points 24V voltage (branch points include car top
control, car control, car display as well as each call board control). The wire size shall not be
less than 0.75mm

.
◇ Cable TXA+ and TXA- is the communication bus between main control and each branch
point.
◇ Where UTP (unshielded twisted pair) is used, it is recommended to select the yellow one for
TXA+ and the green one for TXA-.
◇ Specification of twisted pair: characteristic impedance 120Ω; allowable range: 108~132Ω.
Stranded Pitch: ≤30mm
