Carrier 50RLP installation instructions LID Function Keys, Operative Keys, Numeric Keys

Set the Aquazone™ System Control Panel Controller Address — To set the address of the Aquazone System Control panel controller, perform the following procedure:

1.Press 7 and then SRVC . Press ENTER and then EXPN/EDIT .

2.Type in the CCN element number and press ENTER .

3.Press the button. Type in the CCN bus number and press ENTER .

Log Off from Controller — To log off from the Aqua-

zone System Control panel controller Press 3 and then SET .

Press ENTER . Press the button and then press 1. Press ENTER to log off.

LID Operation — The Local Interface Device (LID) is a CCN operator interface that gives the user the capability to view and modify all configuration and service data for the Aquazone System Control Panel Controller. The LID also gives the user the capability to override all point display and maintenance data.

MENU STRUCTURE — The LID operates on a hierarchy of four levels (menus).

The top level contains the LID’s major functions. Each function has a corresponding key on the LID. For an explana- tion of each function key, refer to Table 7.

The second level separates the major functions (items) into types with corresponding type numbers that can be used for quick access.

The third level gives the user the capability to access each occurrence of an item. For example, the application may require two DO — Analog Comparison algorithms. Thus, the Aquazone System Control Panel Controller would have two occurrences of the DO — Analog Comparison algorithm.

The fourth level gives the user the capability to access main- tenance and configuration data associated with the selected occurrence of the item.

OPERATIVE	USE
KEYS
	Status — gives access to maintenance
	values and configuration data for points.
	Alarm — gives access to maintenance
	and configuration data for alarms.
	History — gives access to maintenance
	and configuration data for history system
	functions.
	Service — gives access to maintenance
	and configuration data for service system
	functions.
	Setup — gives access to configuration
	data for setup system functions.
	Schedule — gives access to maintenance
	and configuration data for schedules.
	Algorithm — gives access to maintenance
	and configuration data for AO, DO, and global
	algorithms. It also gives access to BEST ++™
	custom programs.
	Edit — gives the capability to switch from
	Status mode to Edit (configuration) mode for
	the selected item. (EXPN is not used in
	conjunction with the Aquazone System
	Control Panel Controller.)

DEFAULT SCREEN — Figure 10 shows a LID. This screen provides the user with the 24-character controller name and the controller’s current time, date, and alarm status. This screen appears when the LID is powered up and communicating with the Aquazone System Control Panel Controller or there is no keyboard activity for10 minutes.

KEYPAD AND DISPLAY — The LID consists of a keypad with 8 function keys, 4 operative keys, 12 numeric keys (0 to 9, ., and -) and a two-line, alphanumeric liquid crystal display (LCD). Each line on the LCD can display up to 24 characters. See Fig. 10.

Table 8 below defines the purpose of the LID’s operative keys.

Table 8 — Operative Keys

OPERATIVE		USE
KEYS
		Clear — performs three operations:
	CLEAR	• Cancels a data entry before the user
		presses Enter, thus leaving the current
		value unchanged.
		• Returns a forced point to automatic
		control.
		• Redisplays the previous menu level.
		Enter — performs two operations:
	ENTER	• Selects the displayed item, thus displaying
		either its maintenance or configuration
		data, depending on whether the user is in
		the Status mode or the Edit mode.
		• Accepts the value entered in a configuration
		decision as new configuration data or as a
		force.
		Down arrow — displays the next configured
		item or decision. When the last configured
		item or decision is displayed, the LID
		re-displays the first configured item or
		decision. For example, when the user presses
		the down arrow key while viewing the last
		configuration decision of an algorithm, the LID
		re-displays the first configuration decision.
		Up arrow — Displays the previous configured
		item or decision.

Table 9 below defines the purpose of the LID’s numeric keys.

Table 9 — Numeric Keys

KEYS
-	Numeric keys

Performs two operations:

•Separates items, such as an algorithm from its occurrence or hours from minutes.

•Serves as a decimal point in numeric values.

Performs two operations:

•Negates the value of numeric keys.

•Clears current data entry value any time it is not the first key pressed during the data entry sequence.

VIEWING MODES — The user can view items in either the Status (maintenance) mode or the Edit (configuration) mode.

Status Mode — When the user first powers up the LID, it displays the Aquazone System Control Panel Controller items in the Status (maintenance) mode. The user may view the current value or status of an item in the Status mode without actually logging on to the Aquazone System Control Panel Controller. Knowing the current values or status of items can be useful when troubleshooting. For example, the user could determine if a point was forced.

NOTE: Not all items have maintenance data. If the item you select does not have maintenance data, the LID will display “No maintenance.”
