Voltage Indicator
In order of voltage presence, the corresponding LED would blink for a few seconds, and then it would turn permanently on.
In order of voltage induction of one phase into other phases, all three LEDs would begin to blink with a high frequency .
In order of voltage induction or phase off faults occurrence, after T1 seconds the relay would be turned on for T2 seconds and turned off again (monostable).
The default timers are: T1=0 sec, T2= 400 msec
T1 and T2 are only adjustable by the manufacturer in the time of production, and the user can not change the values.
If one fault is present, and another fault occurs, the relay would operate again.
The maximum load for the output relay is 120 V AC/1 A or 24 VDC/1 A
