The RD6-CT is a multifunction monitoring and protection relay that combines timing, counting, voltage display, over‑/under‑voltage, over‑current, phase‑loss and phase‑sequence protection. It uses a micro‑processor and LCD for intuitive operation and records runtime data such as start counts and fault occurrences.
The manual explains how to use the LCD display, switch between work parameters, respond to alarm conditions, and modify internal settings such as over‑voltage and over‑current thresholds. It also lists the technical specifications and provides step‑by‑step instructions for parameter programming and troubleshooting. This manual is written in Chinese.
| Maximum counting capacity | 999999 counts |
|---|---|
| Maximum timing capacity | 9999 hours 59 minutes |
| Maximum counting frequency | 5 |
| Output contact capacity | 2 A / 250 VAC |
| Voltage display range | 220V~450V AC (three‑phase) |
| Operating temperature | -5°C~45°C |
When an over‑voltage occurs, the LCD flashes “过压”, the output contacts open, and the fault count is incremented.
Press the “细” key to toggle the display among work count, work time, fault count, and fault time.
Modify parameter P1 (over‑voltage setting) within the range 402 V to 600 V.
The device can count up to 999 999 events.
