FIG. 32 – OPER DATA PRINT-OUT
The most recent fault will always be stored as SAFETY
SHUTDOWN NO. 1 (See printout Fig. 33). Identically for-
matted fault information will then be printed for SAFETY
SHUTDOWN NO. 2 and SAFETY SHUTDOWN NO. 3.

Information contained in the SAFETY SHUTDOWN Buff-
ers is very important when attempting to troubleshoot a
system problem. This data reflects the system condi-
tions at the instant the fault occurred and often reveals
other system conditions which actually caused the safety
threshold to be exceeded. See Fig. 33 for a sample of
the History Buffer Printout.
LOCAL DISPLAY READOUT
Oper Data
The OPER DATA key also allows the user to scroll through
additional real time display information about the chiller
system which is not available from the "DISPLAY" keys.
This information covers a wide range of data which in-
cludes fan status, loading status, liquid line solenoid sta-
tus, run time, etc. A total of 15 different displays are
offered.
When the OPER DATA key is pressed, the following
message will appear:
P R E S S
E N T E R
D I S P L A Y
D A T A
Repetitively pressing the ENTER key allows the opera-
tor to scroll through the 15 available displays.
In the information that follows, a sample message along
with an explanation of its meaning is provided for all 15
messages.

The top message provides a real time display of the time
left on the Load Timer. The Load Timer is a constantly
recycling timer that the micro utilizes in conjunction with
"rate control" and "temperature deviation from setpoint"
to determine when loading should occur.
NOTE: This counter may appear to not count according
to actual time. This is a result of the micro's al-
gorithm compensating for changing loading re-
quirements.
The bottom message provides a real time display of the
time left on the Unload Timer. The Unload Timer is a con-
stantly recycling timer that the micro utilizes in conjunc-
tion with "rate control" and "temperature deviation from
setpoint" to determine when unloading should occur.
NOTE: This timer may appear to not count according to
actual time. This is a result of the micro's algo-
rithm compensating for changing unloading re-
quirements.
