When the relay output is set to in local control mode, it indicates corresponding set point
alarm. There are 5 parameters may be set under setpoint alarm feature.
Refer to below
sheet:
Operation object
0 - Prohibit
1 – Voltage
2 – Current
Operation upper limit value
0% - 120% of rating
Operation lower limit value
0% - 120% of rating
Operation time delay
0 - 1200s, 0 means the relay operates
immediately.
Return time
0 - 1200s, 0 means non-return.
Suppose that, Users want to know if there is undervolatge situation. It is required that if in
undervoltage situation, it alarms immediately, until normal voltage is resumed.
The
programming procedure as follow:
