OPERATION
Write parameter values are password protected; however, they may be viewed in the read parameter
menu without entering a password. From the standard display press the /\ key. The display will read
‘Enter Parameter ID:’. Enter the desired write parameter ID, then press the ‘Enter’.
Refer to Section 7: Appendix, for a table of all read/write parameters and their descriptions.
Changing Write Parameter Values
From the standard display or anywhere in the read parameter menu, you may access the write param-
eter menu by pressing the <MENU> key. This will ask for a password. Enter the password and press
the <ENTER> button. Use the /\ or \/ key on the operator interface keypad to scroll through the write
parameters. To change the displayed parameter, press the <ENTER> button. Enter the desired value
and press <ENTER>. If the value entered is outside the acceptable range for the parameter, the original
value will remain. To leave the write parameter menu press the <MENU> button repeatedly until the
standard display shows on the LCD.
Refer to Section 7: Appendix, for a table of all read/write parameters and their descriptions.
Commanding Goal State Changes
From the standard display press the <MENU> key. This will ask for a password. Enter the password
and press the <ENTER> button. The LCD will prompt ‘Change Goal State?’. Press <ENTER> again.
The goal state menu will show on the LCD. Scroll through the goal state menu with the /\ or \/ keys
until the desired goal state is reached. Press <ENTER>. The LCD will prompt: ‘Press F4 to Confirm’.
Press <F4> and the PV-225208 will transition to this goal state. If the goal state requested violates the
conditions of the state machine, the PV-225208 will remain in the previous state of operation.
Setting the Date and Time
From the standard display enter the write parameter menu (see previous). From the ‘Change Goal
State?’ prompt, scroll up with the /\ key until date/time parameter is reached. Press the enter key. The
date/time will be replaced with an underscore. Enter the proper date/time in a six digit format. For
example: The date is entered month-day-year: April 28, 2002 is entered 042802 <ENTER>. The time
is entered in military hours-minutes-seconds: 4:30 pm is entered 163000 <ENTER>. If the date/time is
entered incorrectly the original value will remain. Press <MENU> to return to the standard display.
