PAK Configuration Screens MultiFlex PAK Hand-Held Terminal Interface • 43
Screen 10
The third and fourth lines of this screen con-
tain the eight fields that specify the HP or
amperage rating of condenser fans #1 through
#8. Line three contains the fields for #1 through
#4 (left to right), and line four contains the fields
for #5 through #8 (left to right).
You may enter either the fan motor rating in
HP or in amps, provided all fans controlled by
this PAK use the same unit (in other words, enter
all condenser fan motor ratings either as HP or
as amps).
Screen 11
The third and fourth lines of this screen con-
tain the eight fields that specify the condenser
fan group assignment for fans #1 through #8.
Line three contains the fields for #1 through #4
(left to right), and line four contains the fields for
#5 through #8 (left to right).
For each condenser fan, specify a fan group
assignment from 1-8.

Screen 1
Suct XDucr. Specify the size of the suction
pressure transducer being used in this field. You
may choose 100 lb or 200 lb.
Cond CT Amp Size and Comp CT Amp Size.
The Cond CT Amp Size and Comp CT Amp
Size fields specify the size of the current trans-
ducers (in amps) measuring power consumption
for the condenser and compressor pack respec-
tively. The rating entered here should be the cur-
rent value that corresponds to a 5VDC output
from the current transducer.
LiqDig OK. Choose the digital state of the liq-
uid level sensor that corresponds to "liquid level
OK" in this field. Choose CLSD if the sensor is
CLOSED when the liquid level is OK, or OPEN
if OPEN when OK.
Screen 2
These three fields are used to offset the val-
ues of the Suction Pressure, Discharge Pressure,
and Amb1Temp inputs to correct for sensor inac-
curacies. The value entered in an offset field will
be added to the value as read by the sensor.
Screen 3
These four fields determine how the PAK
will translate the voltage of the Liquid Level
input into a percentage.
Enter the minimum and maximum voltage of
the sensor output in the Liq Level Min V and Liq
Level Max V fields. Then, enter the percentages
represented by these two voltages in the Liq
Level Min and Liq Level Max fields.
