Protection Setting Procedure

Protection Setting Session

The procedure for setting a standard protection function conforms to UL489SE, with an exclusive editing session and a two-step procedure for submitting and applying standard protection setting changes.

Access to the protection function is protected by a PIN code.

The standard protection functions are:

Long time overcurrent protection
Short time overcurrent protection
Instantaneous time overcurrent protection
Ground fault protection
Neutral protection

Two modes of protection setting are available:

Quick settings mode
Fine adjustment mode

The availability of the setting modes depends on the type of standard protection setting, described in Standard Protection Functions.

If the MicroLogic Active control unit power supply is interrupted, use the Mobile Power Pack to enable the protection setting procedure on the MicroLogic Active HMI.
