Service Operation Ð Figure 16 shows an overview of the service menu.

TO ACCESS THE SERVICE SCREENS

1.On the MENU screen, press the SERVICE softkey. The softkeys now correspond to the numerals 1, 2, 3, and 4.

NOTE: The factory-set password is 1 - 1 - 1 - 1. See the Input Service Con®gurations section, page 54, for informa- tion on how to change a password.

2.Press the four digits of your password, one at a time. An asterisk (*) appears as you enter each digit.

If the password is incorrect, an error message is dis- played. If this occurs, return to Step 1 and try to access the SERVICE tables again. If the password is correct, the

softkey labels change to NEXT , PREVIOUS ,

SELECT , and EXIT , and the LID screen displays the

following SERVICE tables:

·Alarm History

·Control Test

·Control Algorithm Status

·Equipment Con®guration

·Equipment Service

·Time and Date

·Attach to Network Device

·Log Out of Device

·Controller Identi®cation

·LID Con®guration

See Fig. 16 for additional screens and tables available form

the SERVICE tables listed above. Use the EXIT softkey to return to the MENU screen.

TO LOG OFF Ð Access the LOG OUT OF DEVICE table from the SERVICE menu. The LID exits the SERVICE menu. To re-enter the SERVICE menu, you must re-enter your pass- word as described above.

NOTE: To prevent unauthorized persons from accessing the LID service screens, the LID automatically signs off and password-protects itself if a key has not been pressed for 15 minutes. The sequence is as follows. Fifteen minutes af- ter the last key is pressed, the default screen displays, the LID screen light goes out (analogous to a screen saver), and the LID logs out of the password-protected SERVICE menu. Other screens and menus, such as the STATUS screen can be accessed without the password by pressing the appropri- ate softkeys.

HOLIDAY SCHEDULING (Fig. 21) Ð The time schedules may be con®gured for special operation during holiday pe- riods. When modifying a time period, an ``H'' at the end of the days of the week ®eld signi®es that the period is appli- cable to a holiday. (See Fig. 14.)

The broadcast function must be activated for the holidays con®gured on the HOLIDEF screen to work properly. Ac- cess the BRODEF screen from the EQUIPMENT CON- FIGURATION table and set the parameter that activates the BRODEF function to YES. Note that, when the chiller is connected to a CCN network, only one chiller or CCN de- vice can be con®gured to be the broadcast device. The con- troller that is con®gured to be the broadcaster is the device responsible for transmitting holiday, time, and daylight- savings dates throughout the network.
