Voltage Protection Relay Instruction Manual
Voltage Protection Relay Instruction Manual
•General
Microprocessor controlled. Three or single phase relay is used in systems exposed to over or under voltage, such as command, control or compensation systems and protects devices such as condensers, motors, air conditioners and compressors. It is divided into sub-categories depending on the voltage adjustment range, on or off start modes.

• Function description:
Voltage normal:
When three-phase voltage is normal, the "OUT"LED flash seconds. After the fault recovery time , setting by potentiometer "Ton", “OUT"LED turns on, and relay is closed.
Overvoltage:
When any line voltage is overvoltage, overvoltage fault indicator ">Un”LED flash seconds.Reaching the fault delay time which setting by "Toff”, relay disconnect, "OUT”LED turn off and Overvoltage failure indicator "〉Un”LED is turn on.If power recover to normal before the fault delay time ,then relay and "OUTLED are not act, still closed; When the overvoltage value is 1.3 times higher, without delay, relay immediately disconnect, Overvoltage failure "〉Un”LED turns on.
Undervoltage:
When any line voltage is undervoltage, undervoltage fault in dicator "vUn''LED flash seconds. Reaching the fault delay time which setting by "Toff, relay disconnect, “OUT'LED turn off,Undervoltage indicator "vUif'LED is turn on.If power recover to normal before the fault delay time ,then relay and "OUT”LED are not act, still closed; When the undervoltage value is 0.7 times lower, without delay, relay immediately disconnect, Undervoltage indicator "<Un”LED turns on
Recover to normal:
When the voltage recover from the fault status to normal, the "OUT"LED flash seconds.fault recover time which is setting by "Ton” has reached,then relay close and output, "OUT'LED turn on; If overvoltage or undervoltage happen before the reaching of fault recovery time ,then relay and "OUT'LED are not act, still disconnected; Over voltage or under voltage indicator light on.
•Phase Sequence:
When Phase sequence errors, the OUT light is off, the relay de-energizes its contact.
