GEK - 105560
Application of voltage
As the MLJ is equipped with instantaneous undervoltage monitoring in two inputs (line and bus), and
with undervoltage and overvoltage levels (live and dead), it can be used as a relay in a large number of
applications such as:
• Undervoltage
• Overvoltage
• Voltage within the limits
• Voltage outside of limits
• Instantaneous or time delayed
In order to do so, the following should be set:
1. The desired settings for the presence or absence of voltage in line and bus (3-1 to 3-4).
2. The enable settings of the undervoltage unit (4-2 to 4-4).
3. The control setting for voltage in line and bus (2-2).
4. The enables for the synchronism unit and synchronism control (4-2 and 2-1).
5. The configured function for auxiliary relays (5-1 and 5-2).
6. The output contact jumpers (normally open or closed).
