DOWNLOADING A PROGRAM FROM A
PROGRAM CARD
The Program card Write Protect Switch
must be in the "Write Protect" position!
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:
C.OPT.nn.nn.nnn
Language Package revision level
(00,01,etc)
Language

white screen appears displaying "Flash Check-
sum Test" and the microboard 7-segment LED
(U22) displays "Ch". While this is displayed, the
microboard is performing a checksum test on the
Program card. This ensures the integrity of the
card before the download procedure can begin. If
the checksum test fails, the card is defective or
corrupted and the download procedure cannot be
performed. If the checksum test passes, the OptiV-
iew Flash PROGRAMMER Screen is displayed.

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.

displays the steps of the programming process
while they are in effect. During the Erasing pro-
cedure, "Er" displayed. During the Programming
