DOWNLOADING A PROGRAM FROM A
PROGRAM CARD
There are 3 steps to the re-programming
process: Erase, Program and Verification.
Once the re-programming process is initi-
ated, it automatically proceeds through
these steps to completion. It cannot be
manually terminated before completion.
Therefore, once the process is initiated,
the existing on-board program will be
erased and replaced by the program in
the Program card. Before proceeding,
be absolutely certain the Program card
is applicable to your chiller model. For
example, if your chiller is a YK chiller,
the Program card used MUST be for a YK
chiller. If a YS chiller program is down-
loaded into a YK chiller, for example, the
chiller will be rendered inoperable until
this procedure is repeated using the cor-
rect Program card!
A label affixed to the Program card contains the card
version. The version is an alpha-numeric code that
identifies the chiller model applicability, language
package and program revision level. The version is as
follows:
Y.OPT.nn.nn.nnn
Language Package revision level
(00,01,etc)
Language Package (0=English
only,1=NEMA,2=CE,3=NEMA/CE)
Controls Revision Level (00, 01,
02, etc)
Chiller Model (01=YK, 02=YT,
03=YS, 05=YR, 11=YD)
OptiView Control Center
Commercial Chiller
Download the program as follows:
1. Remove power to OptiView Control Center.
2. Reposition Microboard DIP switch SW1 position
4 to ON.
3. Insert Program card into Microboard connector
J26.
4. Restore power to OptiView Control Center. A
white screen appears displaying “Flash Check-
sum Test” and the microboard 7-segment LEDs
(U25 and U26) displays “Ch”. While this is dis-
played, the microboard is performing a checksum
test on the Program card. This ensures the integri-
ty of the card before the download procedure can
begin. If the checksum test fails, the card is de-
fective or corrupted and the download procedure
cannot be performed. If the checksum test passes,
the OptiView Flash PROGRAMMER Screen is
displayed.
5. Press START key to start the downloading pro-
cess. A dialog box appears asking if you want to
“Erase Onboard Flash and Re-Program from Pc
Card?”.
Do not proceed until you understand
the above caution!
6.
Use the ► key to scroll to YES.
7. Press
key. The following steps will be per-
formed:
a. Erasing - During this procedure, the program
in the microboard Flash Memory will be
erased. A green bar reflects the progress of
this procedure. The red LED next to this bar
illuminates while this procedure is in prog-
ress.
b. Programming - During this procedure, the
program in the Program card is downloaded
into the microboard Flash memory. A green
bar reflects the progress of this procedure.
The red LED next to this bar illuminates
while this procedure is in progress.
c. Verifying - During this procedure, a check-
sum test is performed on the new program in
the microboard Flash Memory. A green bar
reflects the progress of this procedure. The
red LED next to this bar illuminates while
this procedure is in progress.
The microboard 7-segment LED Displays (U25
and U26) display the steps of the programming
process while they are in effect. During the Eras-
ing procedure, “Er” displayed. During the Pro-
gramming procedure, “Pr” is displayed. During
the Verifying procedure, “Ch” is displayed.
