Cond Temp. The Cond Temp is the condenser
discharge temperature, calculated by converting
the discharge pressure input value to a tempera-
ture.
Disch Press. The current value of the discharge
pressure input. This is the same value as shown
in Status Screen 1, only repeated here for easier
comparison to the other values on this screen.
8.3.4. Status Screen 4
Suct Pres. The current value of the suction pres-
sure input. This is the same value as shown in
Status Screen 1, only repeated here for easier
comparison to other values on this screen.
DB / SP. The number to the left of the slash is
the programmed deadband value around the suc-
tion setpoint. The number to the right of the
slash is the programmed suction setpoint.
Comp Groups. The fourth line of the display
shows the current state of each of the compres-
sor group on the PAK. The characters shown
here, numbered 1 through 8, will be "|" when the
compressor group is active, and "0" when the
compressor group is inactive. Unused groups
will also be shown as "0."
8.3.5. Status Screen 5
Cond TD. The Cond TD is calculated by sub-
tracting the ambient temperature from the con-
denser’s discharge temperature (calculated by
converting the discharge pressure to tempera-
ture). This is the same value as shown in Status
Screen 3, only repeated here for easier compari-
son to the other values on this screen.
DB / SP. The number to the left of the slash is
the programmed deadband value around the con-
denser TD setpoint. The number to the right of
the slash is the programmed condenser TD set-
point.
Cond Fans. The fourth line of the display shows
the current state of each of the condenser fan
groups (corresponding to the fan group outputs
on the PAK). The characters shown here, num-
bered 1 through 8, will be "|" when the fan group
output is active, and "0" when the fan group out-
put is inactive. Unused outputs will also be
shown as "0."
8.3.6. Status Screen 6
Cond Temp. The Cond Temp is the condenser
discharge temperature, calculated by converting
the discharge pressure input value to a tempera-
ture.
DB / SP. The number to the left of the slash is
the programmed deadband value around the cur-
rent condensing temperature setpoint. The num-
ber to the right of the slash is the condensing
temp setpoint, which is calculated by adding the
programmed condenser TD setpoint to the ambi-
ent temp used for control.
VSD. The current operating speed of the VSD,
represented as a percentage of its maximum
speed.
En. The current state of the VSD Enable relay,
which is ON when the VS Fan is called to be ON
and OFF when the VS Fan is called to be OFF.
V. The voltage value shown directly below the
VSD field is the current output voltage of the
PAK analog output controlling the VS Fan.
Fault. The current state of the VSD Fault input.
