Synchronization of certain S3C Case Control system settings
between controls in a line-up is set to ‘on’ by default. The
parameters in Table 4 above marked with an * are duplicated
in all networked controls with the same Rack ID -
d
and
Line-up ID -
Ud
.
After the first control in the line-up is configured via the
Start Up menu through the Display Module, all subsequent
controls on the line-up will synchronize available settings to
simplify set-up. Each time a parameter is synchronized, the
Display Module will momentarily show ‘SYNC’ as shown
below. Once the controller has been set-up, the display will
show the default discharge air temperature.
Note: In able for this feature to function, prior to
setting all control parameters:
1. Each S3C Case Control must contain a unique IP
address. Each control is supplied from Sporlan with a
unique IP address by default. If your installation utilizes
an addressing scheme that necessitates changing this
address it must NOT be done prior to setting up the
controls (See Configuring IP Address).
2. S3C Case Controls in the line-up must be connected to
each other using CAT-5 cabling with RJ-45 plugs wired
as either straight through or crossover Ethernet cables.
3. The Rack ID and Line-up ID must be the same in all
controls in the line-up.
This mechanism operates continuously during operation
to ensure pertinent operating parameters are synchronized
among S3C Case Controls in the line-up. In addition to
these parameters, the Real Time Clocks are synchronized
periodically and coordinated functions such as defrost
termination and lighting control are controlled.
In the event a control in the line-up is replaced or a new one
added, it will receive its line-up level operating parameters
from its peer controllers as soon as it is recognized on the
case – case network by matching its Rack and Line-up ID.
Parameters that are synchronized across the line-up are
located in Section 21.
10. VIEW ONLY MENUS
The view only menus are available by pressing the
▲▼
buttons from the default display after the system has been
set-up. These menus are used as a quick check on system
parameters such as superheat or suction pressures. The
menu will time out after 3 minutes and will return to the
default display.

•
Press the
SET
button to commit the selected parameter value to memory
•
The
ESC
button can be used to exit the value selection for the current parameter. A subsequent press of the
ESC
button will move to the previous parameter.
The set-up is simplified by presenting the user with only the parameter selections required based on previous parameter
value selections. Parameters that can be hidden in the table above are shaded and assigned a number in
parenthesis. The explanations below correspond to those numbers.
