The Cause-of-Tripfunction may also be used in conjunction with the Metered Values menu item. After reading the cause of trip, the operator should enter the Metered Values menu to read the last current that the trip unit recorded before a trip was initiated. In this way the type of trip as well as the magnitude of the current on each phase is known. Pressing the Reset pushbutton clears these values.

3-4.12 FIRMWARE VERSION /REVISION (FW)

This feature allows the operator to read the firmware version and revision of either the trip unit or the OPTIMizer.

3-5 SECURITY PASSWORD

The OPTIMizer Hand Held Programmer utilizes a password to restrict access to certain functional options. A valid password is required to make changes or initiate certain actions within the following main menu options:

•Change Baud/Address•Test Mode•Setpoints•Password•Download

The OPTIMizer Hand Held Programmer is supplied with a factory programmed password of 1000. If it is desirable to establish a new password, follow the procedure outlined in paragraph 3-5.1.

When the programmer is being used, a valid password

can be entered in either of the two following methods:

Method 1: Proceed directly to Password (PA) in the main menu to enter a valid password. Entry of a valid password in this manner will apply to any procedure requiring a valid password as long as the programmer does not turn off. To initially enter a valid password, proceed with the following steps:

N o t i c e : If the programmer automatically turns off or is intentionally turned off, the procedure must be repeated from the beginning. Use of an Auxiliary Power Module will eliminate Auto-Power Down and retain password while unit is on.

Step 1: With the programmer turned on and the main menu displayed, use the Right-Arrowor Left- Arrow pushbuttons to move the blinking cursor to Password (PA) (Figure 3-6).

Step 2: Use the Select pushbutton to enter Password (PA) (Figure 3-7).

Step 3: Use the Right-Arrowpushbutton to select

E n t e r = in the display. A screen that permits entry of a valid password is displayed (Figure 3 - 8) .

Step 4: The blinking cursor indicates which of the four displayed zeros is active and able to be altered. Use the U p or Down pushbuttons to change the active number. Use the R i g h t - A r r o w o r Left-Arrowpushbuttons to move the cursor from one digit to another.

Step 5: Once the password displayed is correct, hold Save p u s h b u t t o n depressed and depress Select p u s h b u t t o n. This simultaneous use of the two pushbuttons will enter the password. If the password entered is valid, Password Accepted will be displayed (Figure 3-9). If the password is not valid, a Password Error message will be displayed momentarily. In both cases the display will automatically return to the main menu (Figure 3-10).

Method 2: Enter a valid password when requested
