Parameter Selection
In the Main menu mode, the parameters are
divided into groups. You select a parameter
groupby means of the navigation keys.

After selecting a parameter group, choose a para-
meter by means of the navigation keys.
The middle section on the display shows the para-
meter number and name as well as the selected
parameter value.

Changing Data
The procedure for changing data is the same whe-
ther you select a parameter in the Quick menu or
the Main menu mode. Press [OK] to change the
selected parameter.
The procedure for changing data depends on
whether the selected parameter represents a
numerical data value or a text value.
Changing a Text Value
If the selected parameter is a text value, change
the text value by means of the up/down naviga-
tion keys.
The up key increases the value, and the down key
decreases the value. Place the cursor on the value
you want to save and press [OK].
Changing a Group of Numeric Data Values
If the chosen parameter represents a numeric
data value, change the chosen data value by
means of the <> navigation keys as well as the
up/down navigation keys. Use the <> navigation
keys to move the cursor horizontally.
Use the up/down navigation keys to change the
data value. The up key enlarges the data value,
and the down key reduces the data value. Place
the cursor on the value you want to save and
press [OK].
Parameter setup modifications
Using quick menu system control modifications
can be handled very simply.
Examples:
1) Switch from open loop control 0-10 v input
to 4-20 mA.
- Change switch 53 from U to I
2) Change from Open Loop factory set to Pro-
cess Loop.
- Select [Quick Menu]
- Select Q3 – PID Closed Loop
- Par: 1-00 change to [3] « Process »
- Par: 3-01 change to [71] « bar »
- Par 3-02 enter pressure sensor low range value
(factory set at -1 bar)
- Par 3-02 enter pressure sensor high range value
(factory set at 12 bar)
- Par 3-10 enter suction pressure adjustment
required as a percentage of the sensor pressure
range (28% for 3.4 bar  -10°C R404A)
- Par 3-13 Select which reference site to activate.
Select Linked to Hand / Auto [0] to use the local
reference when in Hand mode; or the remote
reference when in Auto mode (factory default).
Select Remote [1] to use the remote reference in
both Hand mode and Auto mode.
Select Local [2] to use the local reference in both
Hand mode and Auto mode.
- Par 3-15 Change from Analog input 53 to [0] "No
Function".
- Par 6-24 Preset to -1 bar
- Par 6-25 Preset to 12 bar
- Par 7-20 Preset to analog input 54 (Analog input for
PID control)
- Par 7-33 Process PID Proportionnal gain factory
set to 2
- Par 7-34 Process PID Integral time factor set to 9
s, to e modified in regards to the system inertia.
- Par 13-** are related to smart logic control.
On process control operation this function is
activated by setting 13.00 to "ON".
o Two main controls are handled then
automatically by the CD Compressor Drive:
o 1) compressor working duration avoiding
short cycling and handling oil return from the
refrigeration system to the compressor.
. Par 13-20-0 Minimum time between two starts
is factory set at 5 minutes.
· Par 13-20-1 Minimum running time is factory
set at 0 and has to be adjusted regarding the
system design to avoid tripping on low pres-
sure.
o 2) Pump down function that manages the
compressor On/Off cycle in regards to preset
low pressure values.
· Par 13-12-0 Low pressure cut-in value.
· Par 13-12-1 Low pressure cut-out value
