The manual provides product overview, installation, wiring, operation, and troubleshooting for the ZK-G tension controller.
About this manual
The ZK-G tension controller from Qianwei uses a 128×96 graphic LCD with bilingual display and offers high‑precision tension control for paper, printing, packaging and textile lines. It can output 0‑24 V/4 A to drive magnetic powder clutches or brakes and also 0‑5 V or –5 V to +5 V signals for other actuators.
The document covers mechanical installation options, electrical connection guidelines, menu navigation, tension measurement setup, debugging, additional functions such as cone‑tension control, and a full troubleshooting and maintenance section. This manual is written in Chinese.

Frequently asked questions
What output options does the ZK-G controller provide?
It can output 0‑24 V/4 A to directly drive magnetic powder clutches or brakes, and also 0‑5 V or –5 V to +5 V signals for other devices.
How should the controller be installed and wired?
The controller can be mounted horizontally, vertically, or in a panel opening, and weak‑signal cables must be kept away from power lines to avoid interference.
Which communication protocols are supported?
The device includes optional RS232 or RS485 communication interfaces for connection to PLCs or PCs.
What is the measurement accuracy of the controller?
The tension measurement accuracy is ±0.2 %FS with a resolution of one digit.
