Option 16 – Flash Card Update

A Flash Card is used to input the operating program
into the chiller IPU. A Flash Card is used instead of an
EPROM. Normally, a Flash Card update is not required
and the message above will be displayed.
If the operating software is to be updated, insert the
Flash Card into the Flash Card input port. Turn off the
Unit Switch and set the Flash Card Update to “Enabled”
using the ↑ (UP) and ↓ (DOWN) arrow keys.

Press the ENTER key and the following message will

keypad and display will not respond during the update.
DO NOT reset or power down the chiller until the update
is completed.

After the update is completed, an automatic reboot will
occur. If an error occurred, the following message will
appear with the error code and no reboot will occur:

If the update resulted in an error, the original program
will still be active. When an error occurs, assure the
correct Flash Card was utilized. Incorrect chiller
software will cause an error. If this is not the case, the
Flash Card is most likely defective or the IPU and I/O
combo board is bad.
Incorrect programming may cause
damage to compressors.

List in Table 23, Page 112.
CLOCK
The Clock Display shows the current day, time, and
date. Pressing the CLOCK key will show the current
day, time, and date.
It is important that the date and time be correct, otherwise the
daily schedule will not function as desired if programmed. In
addition, for ease of troubleshooting via the history printouts,
the day, time, and date should be correct.
To change the day, time, and date press the CLOCK
key. The display will show something similar to the
following:
T O D A Y I S F R I 0 8 : 5 1 A M
2 5 J A
N 0 2
The line under the F is the cursor. If the day is correct,
press the ENTER/ADV key. The cursor will move under
the 0 in 08 hours. If the day is incorrect, press the UP
or DOWN arrow keys until the desired day is displayed
and then press the ENTER/ADV key at which time the
day will be accepted and the cursor will move under
the first digit of the “2 digit hour”. In a similar manner,
the hour, minute, meridian, month, day, and year may
be programmed, whenever the cursor is under the first
letter/numeral of the item. Press the UP or DOWN
arrow keys until the desired hour, minute, meridian, day,
month, and year are displayed. Pressing the ENTER/
ADV key will save the valve and move the cursor on to
the next programmable variable.
