HHJ5-M meter is suitable for measuring and counting components in control circuits with AC 50/60Hz, rated working voltage of 380V and below or DC working voltage of 24V. It can automatically measure the length of each steel bar and count the number of batches.
This manual describes the HHJ5-M length counter, a device used with steel‑bar straightening and cutting machines to automatically count bar numbers and measure each bar's length. It explains the device’s functions, wiring, and how to set parameters for total and portion counting modes.
The guide includes technical data, power supply options, signal input methods, counting speed settings, and step‑by‑step procedures for installation, parameter configuration, and normal operation. Safety and wiring recommendations are also provided. This manual is written in Chinese.
| Counting Range | 1 ~ 999 999 |
|---|---|
| Value Coefficient Range | 0.001 ~ 9.999 |
| Counting Speed | Low ≤30 counts/s, High >30 and <1000 counts/s |
| Counting Method | Additive counting, power‑off memory 10 years |
| Contact Capacity | 5 A AC 220 V (resistive) |
| Auxiliary Output Power | DC 12 V 30 mA (max) |
Low‑frequency counting runs at ≤30 counts per second, while high‑frequency counting runs at >30 and <1000 counts per second.
Press the R (reset) key; it clears the portion count display and output state without affecting the total count.
