The Cause-of-Trip function 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 push-
button 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 pass-
word 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 desir-
able 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, pro-
ceed 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-Arrow or 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-Arrow pushbutton to select
E n t e r = in the display. A screen that permits en-
try 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-Arrow pushbuttons 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 mes-
sage 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
