Operating Instructions
1. Set the rated voltage range control knob.
The position of this knob is only taken into account on energisation of the device.If the switch position is changed while the device is opera-
ting, all the LEDs fl ash, but the product continues to operate normally with the vol tage selected at the time of energisation preceding the change of position.
The LED's return to their normal state if the switch is returned to the origin al position selected prior to the last energisation.
2. Set operation threshold value.
3. Set the time delay interval to 0.1s...10s so as to prevent operation in case of transient fault.
4. In case of voltage failure, the relay would be disconnected at the expiration of set time delay interval.
5. If the relay detects voltage failure during electrification, the output relay would be kept in off-state.
6. The measured voltage U <Un*70% indicates open phase fault, and the minimum open phase voltage is 165V.
7. When ZHRV5-03 phase sequence is correct, the output relay would close and the R/T LED would go ON at input voltage (>176V);when ZHRV5- 03 detects phase sequence error and the failure of one or more phases,the output relay would be disconnected,and the R/T LED does not go ON.
8. In case of open phase fault at power input terminals L1 and L2, the function LED would not make indication.
