SECTION 4

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.

MANUAL STATE TRANSITIONS

Refer to previous sections on commanding PV-225208 goal states.

Sleeping Matrix Test Sleeping:

Turn the On/Off switch to the Off position. Command the PV-225208 to Matrix Test. Once the user has completed the test, command the PV-225208 to Sleeping. If the On/Off switch is turned to On while the PV-225208 is in the Matrix Test state, the PV-225208 will transition to Sleeping.
