Depending on the option, the trip voltage for a
specific system or unit high current trip can be
programmed. It also calibrates the current read-
out under the OPER DATA key. The approximate
programmed value is calculated using the following
formulas:
System Trip Volts
For individual system high current trip programming
on chillers:
Add the sum of the compressor and fan RLAs in
the system
Multiply the sum by 1.25
Divide by 225A
The resulting voltage is the value that should be
programmed
For example, if fan and compressor RLAs total 100A:
5V x 100A
x 1.25 =
625VA
= 2.8V
225A
225A
The programmed value will be 2.8V. A similar calcula-
tion and programming will be necessary for the other
system in a 2-system chiller.

The TOTAL NUMBER OF COMPRESSORS is the
total quantity of compressors in the chiller, and deter-
mines the stages of cooling available. Dual system
units may have 4 or 6 compressors.
This MUST be programmed correctly to
assure proper chiller operation.
