Parts Distribution Center (PDC). There is a Program
card for each chiller type (YT, YK, YS, YR, YD, etc)
and each has a unique part number. A label affixed to
the Program card contains the part number and ver-
sion. The version is an alpha-numeric code that identi-
fies the chiller model applicability, language package,
language package revision level and chiller operating
program revision level.
The Program card is applicable to both NEMA and
CE applications. The Program card for YK chillers has
English, Simplified and Traditional Chinese, French,
Portuguese, Spanish, Italian, German, Japanese, Ko-
rean and Hungarian languages.
The program version that is currently residing in the
microboard Flash Memory Chip is displayed as the
“Controls” Software Version on the DIAGNOSTICS
Screen in SERVICE access level.
The Program card obtained from the PDC is pro-
grammed with the latest version of the chiller operating
program. Program cards can be reprogrammed.
A Program card for a particular chiller type can be
used to re-program other chillers of the same type. For
ex-ample, it is not necessary to have more than one
YK Program card. A single YK card can be carried to
dif-ferent locations to re-program other YK OptiView
Control Centers.
A Write Protect Switch on the edge of the Program
card prevents inadvertent writing to the Card during
program downloading.
Handling precautions for the Program card include:
• Do not allow dirt or water to enter the connector
• Operating temperature range for Commercial
grade SD cards is -25°C to 85°C (-13°F to 185°F)
A label on the Program card contains the version and
JCI part number. The version is an alphanumeric code
that identifies the chiller model applicability, lan-guage
package, language revision level and chiller control re-
vision level. The version is as follows:
C.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)

Program Download Connector J26
The SD Program card is inserted into connector J26 to
download a program. Refer to instructions under Ser-
vice Replacement.
FeRAM
The FeRAM (Ferroelectric Ramdom Access Memory)
preserves the stored data during power failures. All of
the programmed Setpoints, Sales Order Data and His-
tory Data is stored here. This memory does not require
a battery.
Real Time Clock
The RTC (Real Time Clock) uses a common CR2032
button-cell lithium battery to maintain the time and
date during power outtages. The battery life is over 10
years. This type of battery is used in watches and is
readily available at drug stores and appliance stores.
SMARC Module
The SMARC Module is the processor card for the
031-03630-001 microboard. The SMARC Module
and the baseboard are assembled as a pair in the board
manufacturing factory and can not be swapped in the
field. SMARC (Smart Mobility ARChitecture) is a
relatively new standard to enable multiple vendors to
provide high performance embedded processor cards.
This will allow using future processors if the current
ones become obsolete without having to re-design the
microboard.
