Motor currents for both System 1 and 2 are displayed
when this pushbutton is pushed.
The minimum limit on the display is 0% FLA. The maxi-
mum limit on the display is 115% FLA.
Operating Hours
Start Counter
Accumulated running hours on each compressor is dis-
played. The counters for an individual system count to a
total of 99,999 hours before rollover. Accumulated starts
on each compressor are also displayed. A total of 99,999
starts can be logged on a system before the counter will
rollover.
The numbers 1 and 2 on the display message indi-
cate 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 the Microprocessor Board
(Fig. 15). Proper programming of the switch is important
during commissioning of the chiller. The OPTIONS dis-
play allows a means of verifying the Dip Switch posi-
tions without looking at or handling the Microprocessor
Board. It also eliminates visual inspection of the some-
times 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 auto-
matically 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 2 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 position.
A detailed explanation of the meaning of each message
and a guide to programming the associated switch is
provided on page 44.
Fig. 15 shows the location and verification of switch po-
sitioning of S1.
* Discharge Pressure Readout is an option. Without this option, the display will read a fixed value.
