All PAK boards whose associated E2 appli-
cations have their "Connected" parameters set to
No will be shown in this screen as status
"Unknown."
7.3. Viewing the PAK Status
Screen
Once you have added a PAK to the E2, you
will be able to see the status of the PAK board(s)
from the front panel.
The PAK Status Screen for the PAK you se-
lected will appear ( Figure 7-2 ).
The PAK Status Screen shows the current sta-
tus of all compressors and condensers. Though
there is a large amount of information on a PAK
status screen, status information is grouped on
this screen in several groups of related informa-
tion in order to make the screen easier to read.
These groups are described below.
7.3.1. Inputs and Set Points
The top four lines of the PAK Status Screen
show the current values of all the important
inputs and set points in the PAK controller.
Suct
The Suct field shows the current value of the
suction pressure. The value shown in smaller
type to the right of the suction pressure field
(enclosed by brackets [ ]) is the suction pressure
control set point, displayed here for reference
purposes.
TD
The TD field shows the current calculated
value of the temperature differential between the
discharge temperature and the ambient tempera-
ture. The value shown in smaller type to the right
of the TD field (enclosed by brackets [ ]) is the
TD set point, displayed here for reference pur-
poses.
Suction Temp
This field shows the value of the PAK’s suc-
tion return gas temperature input.
Liquid Level
This field shows the value of the PAK’s liq-
uid level input.
Comp Amps
This field shows the value of the PAK’s
Compressor Amps input.
Cond Temp
This field shows the condenser discharge
temperature calculated by converting the dis-
charge pressure to temperature based on the sys-
tem refrigerant.
Amb Temp 1
The Amb Temp 1 field shows the current
value of the ambient temperature sensor on the
condenser.
Disch
This field shows the current value of the dis-
charge pressure transducer.
Cond Amps
This field shows the current value of the
PAK’s Condenser Amps input.
