Description
Mode of Operations:
Over Voltage
The relay will release if the voltage exceeds the set limit. If the voltage reduces by the percentage hysteresis of the set value the relay will operate. Refer to the delay settings for operation delays.
Under Voltage
The relay will operate if the voltage exceeds the set limit. If the voltage reduces by the percentage hysteresis of the set value the relay will release. Refer to the delay settings for operation delays.
Hysteresis
Hysteresis is the percentage difference between the trip point and the recovery point. If the unit is set to 100V over voltage 10% hysteresis, the relay will release at 100V and only re-energize when the voltage falls to 100V – 10% = 90V.
Delay Functions
1.) No Delay
Measurement start immediately and relay responds directly (normal acquisition delay apply).
2.) 10s Startup
Relay operates immediately and power LED flashes when power supply is applied. Measurement starts after 10 sec and power LED stops flashing.
3.) 180s Response Delay
When power is applied relay does not operate and power LED flashes. After 180sec measurement starts and power LED stops flashing. If relay releases, time delay start, power LED flashes and relay will only operate again after 180sec.
4.) 10s Recovery Delay
Relay operates immediately and power LED flashes when power supply is applied. Measurement starts after 10 sec and power LED stops flashing. If relay releases, it will only operate if conditions have recovered for 10 sec.
