Phase Monitoring Relays
Soft start function;
Soft stop function (soft stop can be set to 0 or soft stop to soft start value or closed);
Phase sequence protection function (can be set to open or close);
Both functions of can be set to off or on.
1. With soft start and soft stop (to the start value or 0), with phase sequence protection
2. With soft start and soft stop (to the start value or 0), no phase sequence protection
3. With soft start, no soft stop, with phase sequence protection
4. With soft start, no soft stop, no phase sequence protection
A total of 6 states of the module can be arbitrarily set, flexible and powerful.
The initial state is: with soft start, no soft stop, and no phase sequence protection.
If you need to set other states, you can consult customer service or refer to the manual.
For example: if the module state is set to soft stop to 0, there is phase sequence protection and the two potentiometers are turned to the corresponding positions of 150v and 20s respectively.
At this time, the main circuit is energized, the control terminal switch is closed (or 5-24Vdc), the output voltage of the module will slowly rise from 150V to 38OV, and the time is 20s;
If the control terminal switch is disconnected (or disconnected from 5-24Vdc), the output voltage of the module will slowly drop from 380V to 0V for 20s.
(If the soft-stop setting is to stop to the soft-start value, the output voltage of the module will slowly drop from 38OV to 150v for 20s, and then turn off immediately).
