Field Overcurrent (see Par. 3.6.2):
❑
Maximum Current (A): enter in this field the max. allowed field current level value (0 to 15A, with min. increase of 0.1A).
❑
Time Delay (s): enter in this field the time interval value, during which the MEC-100 is authorized to supply the Maximum
Current before the activation of the relevant protection (0 to 10s, with minimum increase of 0.1s).

Enable Protection: protection activation flag; click on this button to activate the field over-current protection function.

Apply to Relay 1: relay 1 assignment flag; click on this button to assign the protection intervention signal to relay 1.

Apply to Relay 2: relay 2 assignment flag; click on this button to assign the protection intervention signal to relay 2.
Field Overvoltage (see Par. 3.6.1):
❑
Voltage Threshold (V): enter in this field the maximum allowed field voltage level value (0 to 200V, with minimum increase
of 1V).
❑
Time Delay (s): enter in this field the time interval value during which the MEC-100 is authorized to supply the Voltage
Threshold value, before the activation of the relevant protection (0 to 10s, with minimum increase of 0.1s).

Enable Protection: protection activation flag; click on this button to activate the field over-voltage protection function.

Apply to Relay 1: relay 1 assignment flag; click on this button to assign the protection intervention signal to relay 1.

Apply to Relay 2: relay 2 assignment flag; click on this button to assign the protection intervention signal to relay 2.
BY DEFAULT, PROTECTIONS ARE INITIALLY DISABLED. Pay particular attention, when configuring the MEC-
100, to the activation of all concerned protections.
5.7.8. Generator Protections
In Fig. 5.7.8.a the generator protection parameters configuration area is shown.
Generator Overcurrent (see Par. 3.6.5):
❑
Maximum Current (%): enter in this field the maximum allowed generator current level value related to the following Time
Delay, and expressed in percentage with respect to the generator rated current value (0 to 120%, with minimum increase of
1%).
❑
Time Delay (s): enter in this field the time interval value during which the MEC-100 is authorized to supply the Maximum
Current, before the activation of the relevant protection (0 to 3600s, with minimum increase of 1s).
❑
Maximum Continuative Current (%): enter in this field the maximum continuous generator current value, expressed in
percentage with respect to the generator rated current value (0 to 110%, with minimum increase of 1%).

Enable Protection: protection activation flag; click on this button to activate the generator over-current protection function.

Apply to Relay 1: relay 1 assignment flag; click on this button to assign the protection intervention signal to relay 1.

Apply to Relay 2: relay 2 assignment flag; click on this button to assign the protection intervention signal to relay 2.
Generator Overvoltage (see Par. 3.6.3):
❑
Voltage Threshold (%): enter in this field the maximum generator voltage level value which corresponds to the activation of
the relevant protection. It is expressed in percentage with respect to the generator rated voltage value (100 to 150%, with
minimum increase of 1%).
❑
Time Delay (s): enter in this field the time interval value during which the MEC-100 is authorized to supply a voltage higher
than or equal to the Voltage Threshold value, before the activation of the relevant protection (0 to 300s, with minimum
increase of 1s).
