Each of the user commands can be initiated by following the general command entry procedure outlined below.

General Command Entry Instructions:

1. A user command can be performed only when the following conditions are all satisfied:

a.) Mode switch is not

in the RUN position,

b.) One of the green Command Set lights (a, b, c) is blinking,

c.) ADJUST switch is not

in the MINIMUM position,

d.) Unit is “unlocked”, and

e.) For some commands, the unit must be in a specific mode, position index, etc. (See command entry requirements listed on

page 10-30.7-56 or in Reference Tables 12 through 14 on pages 10-30.7-80 through -84.)

Note: Condition d. above is not required for Command A-7, Unlock Configuration and Command A-1, Display Alarm Codes.

2. If the a, b, or c Command Set light is not blinking, momentarily push the MODE switch in the CMD abc position (up) or, change

the position of the rotary CMD SEL switch. This will start the Command Set light blinking and permit a command to be

entered.

3. Select the desired Command Set by momentarily pushing the MODE switch upward to the CMD abc position. Subsequent

CMD abc switch entries will change the command set selection as indicated by the green Command Set (a, b, c) lights.

4. Select the desired command number by changing the position of the rotary CMD SEL switch. When one of the command set

lights is blinking, the command number selected is indicated by the corresponding numbered (0-9) light being lit.

5. After the command set and number are selected, press the ENTER button. If all of the numbered lights flash momentarily

after the ENTER button is pushed, a command entry error has occurred and the command was not executed. If an entry error

occurs, check to see if the unit is locked (i.e. alarm light blinking) or the ADJUST switch is in the MINIMUM position. If neither

condition exists, check the specific entry requirements of the command.
