Description of Function diagram and LED
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 operating, all the LEDs flash, 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.After the relay is powered on, the output relay would not close until the reset delay time elapses.
3. In case of voltage failure, the relay would be disconnected at the expiration of set time delay interval.
4. If the relay detects voltage failure during electrification, the output re lay would be kept in off-state.
5. The measured voltage U<Un*70% indicates open phase fault.
6. In 3 phase 3 wires system(M440) phase fault at power input terminals L1 and L3, the function LED would not make indication.
In 3 phase 4 wires system(M254) phase fault at power input terminals L1 and L3, the function LED would not make indication.
