Operating Instructions

Un
1.Select operating function selector knob ;the relay takes a reading of operating functions after power-on.In case of knob setting error, LED will flash at the same time, which indicate the setting error. Normal operation will be resumed through resetting after power-off. If the operating function is
changed after power-on, all LED indicators would flash while the relay operates based on original operating functions;the LED would resume the normal indication after the original setting is recovered.
2.Regulate the Voltage threshold adjusting knob to set protection threshold
value.
3.Regulate the h ysteresis control knob ; hysteresis is 5%...20%of threshold
value.
4.When measured volte exceeds the set threshold value of voltage,R/T
LED would flash and the UE LED would go ON . When fault time exceeds the set time delay(0.1s...10s) interval,output relay would be disconnected and R/T LED would go OFF.
5.When "over-voltage, non-locking" mode is activated, if the operating voltage is less than the difference between voltage threshold value and lagged
value , the output relay would be actuated and the R / T LED would go
ON . When "under-voltage, non-locking" mode is activated, if the operating
voltage is more than the sum of voltage threshold value and lagged value,
the output relay would be actuated and the R / T LED would go ON .
6.In case of "locking" mode, the operating voltage exceeds threshold value
and output relay would keep an off-state. The power must be turned off before resetting the relay.

1.Regulate the overvoltage and undervoltage threshold adjusting knob threshold value . The set overvoltage threshold value must be larger than undervoltage threshold value. Otherwise, all LEDs would flash and the output relay would be disconnected.
2.Fixed Hysteresis is 5% .
3.When measured voltage exceeds the threshold value, R/T LED would flash
and the U> (U<) LED would go ON. When fault time exceeds the set time delay(0.1s...10s) interval, output relay would be disconnected and R/T LED
would go OFF.
4.When operating voltage is lower than the difference between overvoltage
threshold value and lagged value or higher than the sum of undervoltage
and lagged value,the output relay would be actuated and the R / T LED
would go ON .
Note: hysteresis = set threshold value * set hysteresis value .
