Downloading and Viewing Graphs
The unit controller continuously records and stores sensor
input and relay/analog output data. This data is collected in 10-
second (default) intervals. The controller stores 1008 packets
of data replacing the oldest with the newest. With the time
interval set at 10 seconds, graph data can be downloaded with
a time span of 168 minutes. The time interval is adjustable.
In the MCS-CONNECT software, select GRAPH. Data will be
downloaded and then a graph setup page will appear. Select
the input and output data to be viewed. Type in Y-axis
parameters and select OK. Use the scroll bar at the bottom of
the graph to view. Return to the setup page at any time to
change selections. The graph may be saved. The saved graph
will be located in a folder called GRAPH inside another folder
called MCS on the C: drive.
To change the default 10-second interval, make changes and
select SAVE and then OK on the setup page. The controller will
now record data at this new interval.
To view a saved graph, select LOAD A GRAPH FILE. These
files can be e-mailed for analysis if needed.
Updating Chiller Software and
Configuration Files
CICD chillers are programmed, set up, and tested prior to
shipment. Sometimes after a unit arrives at the jobsite, the
customer may want to enable an option such as 0–5 Vdc target
reset, etc. These options require a configuration change. The
configuration file must be downloaded and electronically sent
to the factory for the changes to be made or the factory may
modify a default configuration file and electronically send the
modified default configuration to the customer. Modifying a
configuration file will save any setpoint changes that have
been made on site. Otherwise, the controller will be set back
to default factory settings.
To e-mail a copy of the chiller's configuration file, in the MCS-
CONNECT software, establish communication with the chiller
and select RECEIVE CFG.
Name it "Unit (serial number)" and e-mail to
engineering@nappstech.com.
To load a configuration file, turn off circuit enable switches and
select TRANSMIT CFG. Locate the new file and press OPEN.
The file will be uploaded to the controller. The controller will
reboot itself.
Routine software (HEX FILE) updates are NOT necessary.
However, if a software update is necessary to resolve an
operating issue, a hex file in a zipped folder will be provided.
Save the zipped folder to the computer's desktop. Right click
folder and select EXTRACT ALL. This will create another
folder by the same name on the computer's desktop. Inside
this folder will be the hex file. It should be about 2300 KB. In the
MCS-CONNECT software, select TRANSMIT SW. Locate the
extracted hex file and select Transmit. Watch the chiller LCD
screen. After the file is uploaded, the CICD unit controller will
verify that it's a valid file and then erase the flash memory. Next,
it will write the new hex to memory. When completed, the
controller will reboot itself. This process may take 15 or 20
34
minutes. After the reboot is completed, close and restart the
MCS-CONNECT software to reestablish communication with
the chiller.
