Instructions
How to Program on the Graphical Local
Control Panel
The following instructions are valid for the gra-
phical LCP (LCP 102):
The control panel is divided into four functional
groups:
1. Graphical display with Status lines.
2. Menu keys and indicator lights - changing
parameters and switching between display func-
tions.
3. Navigation keys and indicator lights (LEDs).
4. Operation keys and indicator lights (LEDs). All
data is displayed in a graphical LCP display, which
can show up to five items of operating data while
displaying [Status].
Display lines
a. Status line:Status messages displaying icons
and graphic.
b. Line 1-2: Operator data lines displaying data
defined or chosen by the user. By pressing the
[Status] key, up to one extra line can be added.
c. Status line: Status messages displaying text.

LCP keys
The control keys are divided into functions. The
keys below the display and indicator lamps are
used for parameter Set-up, including choice of
display indication during normal operation.
[Status] indicates the status of the frequency
converter and/or the motor compressor. You can
choose
between 3 different readouts by pressing the
[Status] key: 5 line readouts, 4 line readouts or
Smart Logic Control by pushing twice the [status]
key.
Use [Status] for selecting the mode of display or
for changing back to Display mode from either
the Quick Menu mode, the Main Menu mode or
Alarm mode. Also use the [Status] key to toggle
single or double read-out mode.
[Quick Menu] allows quick access to different
Quick Menus such as:
01 - My Personal Menu
02 - Quick Set-up
03 – PID Process Loop
04 - Changes Made
05 - Loggings
Use [Quick Menu] for programming the parame-
ters belonging to the Quick Menu. It is possible to
switch directly between Quick Menu mode and
Main Menu mode.

Quick setup
The following lines describe the basic procedure
to run the CD302.
1) Connect the power supply to the terminals (L1,
L2 and L3) of the CD302 as shown on page 7 of
this manual.
2) Connect motor cable between the Drive (U, V &
W) and Compressor (Clockwise on terminal), see
picture of page 4.
(The connectors utilised in this first 2 steps are
provided in the accessory bag which accompa-
nies the CD302)
3) Press "Quick menu" and go to quick setup. En-
sure that the correct compressor model is selec-
ted in parameter 1-13.
4) Make connections between the terminals 12
and 18 (start signal), connections between termi-
nal 12 and 27 (inverse coast signal) and terminals
12 and 37* (safe stop inverse signal). See pictures
on page 9.
* (Please read also on pages 11 and 14 the chap-
ters about Safe Stop)
When the above connections are made the
compressor will start automatically.
If an error that causes the Drive to trip is
detected, it will automatically try to restart the
compressor after 30 seconds (unless the error is
severe and causes a trip lock). See also parame-
ters 14-20 and 14-21.
Open Loop with external reference
5) Apply analogue speed reference signal (0-10V)
on terminal 53 using the terminal 55 as common.
The wiring diagram is on page 10 of this manual.
6) Check over if the switch A53 is flicked to U
(voltage) instead of I (current). The switch A53 is
located on the drive and can be seen when the
LCP is removed.
7) Ready to Run: If the Drive is supplied with dis-
play: Use "Hand on" to set a local speed reference
in the display (good for testing purposes). Use
"Auto on" for running in operation and with an
external reference.

8) Done.
PID closed loop with 4-20 mA pressure trans-
mitter:
9) Connect pressure transmitter to analogue
input on terminal 54 according to the schema on
page 10.
10) Make sure that the switch for analogue input
54 is set to "I" for current input.
11) Press "Quick Menu" button and go to "PID
Closed Loop" menu. Now change parameters to:
• 1-00: Select: "Process"
• 3-01: Select: "Bar"
• 3-02 + 3-03: Enter the lower and upper limits of
the set-point range [bar].
• 3-15: Set to "no function" for fixed set-point.
• 6-22 + 6-23: The values of these parameters
should match the output of the pressure trans-
mitter (4-20 mA for example is the factory set-
ting).
• 6-24 + 6-25: Set range of pressure transmitter
(factory setting -1/+12 bar).
• Go back to 3-13: Select "Local" to run with a fixed
set-point adjustable via keypad. Select "Remote"
