Operating Hours
Start Counter
Accumulated running hours on each compressor is dis-
played. The counters for an individual system count to a
total of 99999 hours before rollover. Accumulated starts
on each compressor are also displayed. A total of 99999
starts can be logged on a system before the counter will
rollover.
The numbers 1 and 2 on the display message indicate
compressor #1 and compressor #2.
These counters are zeroed at the factory or will indicate
only run time and number of starts logged during factory
testing at the time of shipment.
Options
The OPTIONS key provides a display of options which
have been selected by the user. These options are se-
lected by the S1 Dip Switch on each Microprocessor
Board (Fig. 12). Proper programming of the switch is
important during commissioning of the chiller. The OP-
TIONS display allows a means of verifying the Dip Switch
positions without looking at or handling the Microproces-
sor Board. It also eliminates visual inspection of the
sometimes difficult to determine Dip Switch position.
When the OPTIONS KEY is pressed, the following mes-
sage will first be displayed for 3 seconds:
8 Option Messages will then follow. Each will be dis-
played for 3 seconds before the next display is automati-
cally indexed. When all messages are displayed, the
display message will automatically change to show a
chiller STATUS message, just as if the Status key was
pressed.
Refer to Table 1 for a list of the displays and the corre-
sponding switch positions in the order they appear. Two
possible messages may appear for each of the eight
messages depending on the Dip Switch is provided posi-
tion.
A detailed explanation of the meaning of each message
and a guide to programming the associated switch is
provided on page 28.
Fig. 12 shows the location and verification of switch posi-
tioning of S1.
* Discharge Pressure Readout is an option. Without this option, the display will read a fixed value.
