Editing Fields on the Controller
After navigating to the desired screen (notice that the blinking
cursor is in the top left corner of the screen when navigating
data screens), editing is accomplished by pressing the ENTER
key (lower-right key on the controller) until the desired field is
selected. The selected field is indicated by the blinking cursor
under it. The arrow keys then operate as follows:
• DEFAULT (← Key): Set value to original factory setting.
• CANCEL (→ Key): Reset the current field to the value it
had when editing began.
• INCREMENT (↑ Key): Increase the value or select the
next item in a list.
• DECREMENT (↓ Key): Decrease the value or select the
previous item in a list.
During “edit” mode, the display shows a two-character wide
menu pane on the right of the screen (in bold font below) to
help associate the correct arrow keys with their operating
action.
SET COMP SPs (1) <D
Demand Limit=Off <C
Minimum Amps=010% <+
MaximumAmps=100% <-
Once the desired value has been selected using the
appropriate keys, press the ENTER key to except this setting
and jump to the next setting (field) in the mask.
When the last field is selected, pressing the ENTER key
switches the display out of “edit” mode and returns the arrow
keys to “scroll” mode, as indicated by the blinking cursor
positioned in the upper left corner of the mask.
Setting Passwords
Two separate passwords provide operator and manager
levels of access to changeable parameters (the technician
level password is only available to McQuay International
technicians):
• Operator Level Password = 100
• Manager Level Password = 2001
Either password can be entered using the SET PASSWORD
screen/mask, which can be accessed in one of two ways:
1. Attempt to alter a setting without the appropriate
password being active.
2. When navigating through the screens, scroll right just
past the SET TOWER SPs column. (See "Table 19:
Menu Matrix" on page 50 .)
Either of these two methods will cause the following screen
to be displayed. The gray background indicates where the
blinking cursor will be. The second row will say either “Enter
Operator”, “Enter Manager”, or “Enter Technician” depending
on the password level required for the screen that was on the
controller prior to accessing the SET PASSWORD screen.
SET PASSWORD
Enter
Password:00000
No Access Given
Once the SET PASSWORD screen is displayed, change the
password using the following method (the example screens
below show operator level; however, the same method is used
for manager or technician level):
1. Press the ENTER key on the controller to access “edit”
mode. The blinking cursor will move to the “Password”
field.
SET PASSWORD <Left
Enter Operator <Rght
Password:00000 <+
No Access Given <-
2. Enter the password for the required password level.
Note that the password must be entered one digit at
a time. Use the LEFT and RIGHT arrow keys to move
horizontally across the password from one digit to the
next. Use the UP and DOWN arrow keys to select the
appropriate number for each digit.
3. Once the password has been entered, press the ENTER
key. Notice that the blinking cursor will move to the right
of the password, rather than being behind any of the
digits.
SET PASSWORD <Rtry
Enter Operator <Exit
Password:00100
No Access Given <Void
4. Press the RIGHT arrow key to “Exit.” If the SET
PASSWORD screen was initially accessed by attempting
to alter a setting on a screen without the appropriate
password active, “Exit” will cause that prior screen to be
displayed. If the SET PASSWORD screen was initally
accessed via scroll navigation, “Exit” will go to the VIEW
UNIT STATUS (1) screen. If the ENTER key is pressed
instead of pressing the RIGHT arrow key to “Exit,”
the blinking cursor will go back to the top left corner
of the SET PASSWORD screen, indicating that scroll
navigation can continue using the arrow keys.
NOTE: Once a password has been entered, it shall remain
valid for 15 minutes after the last key-press. Only
the chiller with the active password is unlocked. All
screens are visible, but only screens with the required
access password active will allow changes to their
settings.
