Setting Protection in Accordance With UL489SE Standard

Presentation

The procedure for setting a protection setting conforms to UL489SE standard. It is safeguarded by an exclusive editing session and by a two-step procedure for submitting and applying setting changes.

The exclusive editing session means that only one interface at a time can access and set protection settings. Access from other interfaces is blocked when an editing session is open.

During the editing session there is no impact on the active protection provided by the MicroLogic X control unit until the new settings are applied. If the new settings are canceled, or the editing session times out before the new settings are applied, the active settings are maintained.

Settings for standard protection functions can be set from the following interfaces:

oOn the MicroLogic X display screen, at Home > Protection

oWith EcoStruxure Power Commission software (password-protected)

oWith EcoStruxure Power Device app (password-protected)

oBy sending setting commands using the communication network (password-protected)

Settings for optional protection functions, including the ERMS function, can be set from the following interfaces:

oWith EcoStruxure Power Commission software (password-protected)

oWith EcoStruxure Power Device app (password-protected)

For more information about password management, refer to the password description.

The protection settings displayed in Quick View are the active protection settings applied on the installation.

To set a protection setting, access to protection settings must be enabled on the MicroLogic X HMI.

Enabling and Disabling Access to Protection Settings

You can enable or disable access to the protection settings by using the MicroLogic X display screen at Home > Configuration > General > Lock protection.

 From the Lock protection screen of the MicroLogic X control unit, you can allow changes to the protection settings from the following interfaces:

oKeypad: MicroLogic X display screen keypad itself

oExternal access: EcoStruxure Power Commission software, EcoStruxure Power Device app, and communication network

For each interface:

oSet as Allowed (factory setting) to enable changes to be made.

oSet as Not Allowed to disable changes.

Enabling access to protection settings generates two events:

Editing Session for Selecting and Changing Protection Settings

An editing session has the following characteristics:

oOnly one editing session at a time can be open. Access to protection settings from other interfaces is blocked when you open an editing session. A pop-up notice is displayed if a session is already open.

oThere is a five-minute timeout for submitting and for applying new settings. The session times out as follows:

oFive minutes after the session opens, if you do not submit the new settings

oFive minutes after submitting the new settings, if you do not apply the new settings

NOTE: When setting protection on the MicroLogic X display screen keypad, if the Quick View timeout is set up as less than five minutes, the editing session times out at the end of the time set for Quick View timeout.

oAfter applying new settings, close the editing session.

oWhen changing protection settings on the MicroLogic X display screen keypad, only one protection function can be set per editing session. Open a new editing session to make changes to a second protection function.

oWhen changing protection settings on EcoStruxure Power Device app or through communication, several protection functions can be set in one editing session, with a submit step after making changes to each function and one apply step to apply all the new settings of a given setting group (A, B, or ERMS). Active settings are maintained until the apply step is executed.

Two-Step Procedure for Submitting and Applying Protection Settings

The procedure for changing protection settings requires you to submit and apply the new settings in two consecutive steps:
