6.3 Entering refrigeration point parameters
Name of refrigeration point
- In the Main Menu choose item 7 Monitoring.
- In the Monitoring menu choose item 3 Configuration.
- Select the case/coldroom controller to be named by scrolling with the cursor keys or entering the CAN bus
address (and confirming with ENTER), then confirm by pressing the ENTER key. The flashing cursor moves
from the first line to the second.
- The up and down cursor keys (
↑
) and (
↓
) can be used to move the flashing cursor to Line 2, 3 or 4.
- Press the ENTER key to place the cursor at the beginning of the entry field.
- Then enter the name, Item ID and priority (0, 1 or 2) of the refrigeration point and confirm by pressing the
ENTER key.
Priority can also be configured from the Main Menu by choosing item 5 Remote Operation (selected
case/coldroom controller), 6 Configuration, 1 Refrigeration Point, Priority.
For actual configuration of the refrigeration point, "dial up" the case via remote operation:
- In the Main Menu choose item 5 Remote Operation.
- Select the controller to be configured by scrolling with the cursor keys or entering the CAN bus address
(and confirming with ENTER), then confirm by pressing the ENTER key.
This displays the Refrigeration Point menu showing position of the selected case controller. You should first
choose item 6 Configuration, as this narrows down the selection of functionalities. The refrigeration point para-
meters must then be set under menu items 2 Setpoints and 3 Clock. See also Section 4 − Installation and Star-
tup of UA 300 D.
6.4 Operation with BT 300 x Operator Interface
When using the UA 300 D in stand−alone mode, the case/coldroom controller can only be operated with the
BT300 x Operator Interface. A local set−up unit can be connected to a separate interface (display). The operating
options are largely the same as those provided in the remote operation menu of the AL 300 Operator Terminal or
CI 3000 Store computer (see chapter 6.2).
Constraints result from the use of a smaller display and a smaller number of keys. Naming of the refrigeration
point is only possible with controllers of type UA 300 D and UA 300 L.
If no key is pressed, the display of the local set−up unit will show case operating status and return air tempera-
ture. Differences between the displayed value and the thermometer reading can be compensated by entering
an offset for this value.
Press the ENTER key (
↵
) to change from the status display to the operating menus. A jumper is fitted next to
the keypad ribbon cable inside the unit. Removing or shifting this jumper results in the unit no longer being usa-
ble to make settings.
A local Operator Interface can also be used to operate case controllers in a CAN bus system. This
is however less convenient than using the CI 3000 Store Computer, AL 300 Operator Terminal or
LDSWin software.
