The chiller operating program resides in the Optiview
control center Microboard. The control center could be
equipped with either of the following Microboards:
•
031-01730-000 – shipped in new production chill-
ers until January 2004. The program resides in a
replaceable Flash Memory Card. The software ver-
sion (C.MLM.01.xx.yzz) is printed on label adhered
to card. Program can be upgraded by replacing the
card.
•
031-02430-000 – shipped in new production chill-
ers between January 2004 and June 2006. The pro-
gram resides in non-removable onboard memory.
The software version is C.OPT.01.xx.yzz, and is
viewable on the DIAGNOSTICS Screen in SER-
VICE access level. The program can be upgraded
by downloading a new program from a Program
Card. Program Cards are shirt-pocket-size portable
memory storage devices available from YORK.
•
031-02430-001 – Shipped in new production chill-
ers after June 2006. This is an upgraded version
of the 031-02430-000 microboard. The upgrade
is necessary to operate with the Medium Voltage
Solid State Starter, Medium Voltage Variable Speed
Drive and those Variable Speed Drives and Style B
Solid State Starters that serially communicate with
the microboard using Modbus Protocol. Variable
Speed Drive Modbus applications require Software
version C.OPT.01.16.307 (or later). Style B Solid
State Starter Modbus applications require Software
version C.OPT.01.18.307 (or later).
The upgrade includes a larger BRAM (U38) and
an additional RS-485 port on COM2 serial port
for Modbus communications. When used in larger
BRAM configuration, requires software version
C.OPT.01.15.xxx (or later). This board is backward
compatible with YK chillers presently using the
031-01730-000 or 031-02430-000 microboard.
Earlier vintage chillers could be equipped with a later
Microboard due to service replacement.
Software versions
(C.MLM.01.xx.yzz or C.OPT.01.
xx.yzz)
are alpha-numeric codes that represent the appli-
cation, language package and revision levels per below.
Each time the controls portion or language section is
revised, the respective revision level increments.
•
C – Commercial chiller
•
MLM – Used on Microboard 031-01730-000
•
OPT - Used on Microboard 031-02430-000
•
01 – YK chiller
•
xx - controls revision level (00, 01, etc)
•
y – language package (0=English only, 1=NEMA,
2=CE, 3=NEMA/CE )
•
zz – language package revision level (00, 01, etc)
Throughout this book, reference is made to functions
and features that are only available in certain Flash
Memory Card revision levels (C.MLM.01.xx.xxx). To
cross reference C.MLM software to C.OPT software,
refer to the controls revision level. Software version
C.OPT.01.08A.300 is of the same controls revision
level as C.MLM.01.08.105A/.206A. From this starting
point, both receive the same updates at each revision.
Software upgrades should only be performed by a Ser-
vice Technician.
