Operating AKM / Service tool
The setup of the controller itself can only be carried out via AK-ST
500 service tool software. The operation is described in fitters on
site guide.
If the controller is included in a network with an AKA gateway one
can subsequently carry out the daily operation of the controller
via AKM system software, i.e. one can see and change daily read-
outs/settings.
Note: AKM system software does not provide access to all
configuration settings of the controller. The settings/read-outs
that may be made appear in the AKM menu operation.
The following limits exist:
Up to 8 thermostat functions
Up to 2 pressostat functions
Up to 2 voltage functions
Up to 2 energy measurements
Up to 8 DI functions.
If a larger number are defined than the ones set out above, AKM
will be able to receive alarms from the functions, but the functions
cannot be operated from AKM.
Authorisation / Passwords
The controller can be operated with System software type AKM
and service tool software AK-ST 500.
Both methods of operation provide the possibility for access
to several levels according to the user's insight into the various
functions.
System software type AKM:
The various users are defined here with initials and key word.
Access is then opened to exactly the functions that the user may
operate.
The operation is described in the AKM manual.
Service tool software AK-ST 500:
The operation is described in fitters on site guide.
When a user is created, the following must be stated:
a) State a user name
b) State a password
c) Select user level
d) Select units – either US (e.g. °F and PSI) or Danfoss SI (°C and
Bar)
e) Select language
Access is given to four user levels.
1) DFLT – Default user – Access without use of password
See daily settings and read-outs.
2) Daily – Daily user
Set selected functions and carry out acknowledgement of alarms.
3) SERV – Service user
All settings in the menu system except for creation of new users
4) SUPV – Supervisor user
All settings including the creation of new users.

Display signal
The values measured can be read from a display. This display must
be of display type EKA 163B or EKA 164B. Up to four displays per
controller can be fitted.
Connection is effected by means of wires with plug connectors.
The display can be placed on an appliance front, for example.
When a display with operating buttons is selected, the unit can be
operated with ease by means of a menu system as well as display-
ing temperatures and operating situations. E.g. the alarm relay can
be reset by pressing the top button.
LEDs on the front
The LEDs will flash when an alarm has been triggered.
In this situation, you can call up the error code on the display by
briefly pressing the top button.
The buttons
When you want to change a setting, the top and bottom buttons
will give a higher or a lower value depending on which button
you press. Before you can change the value, you must access the
menu. This is done by holding down the top button for a couple
of seconds; this takes you into the list of parameter codes. Find the
parameter code you want to change, then press the centre but-
ton to display the parameter value. When you have changed this
value, save the new value by pressing the centre button again
Examples:
Setting a menu
1. Press the top button to display a parameter
2. Press the top or bottom button and find the parameter you
want to set
3. Press the centre button to display the value
4. Press the top or bottom button and set the new value
5. Press the centre button again to save the value.
Get off to a good start
The following procedure will start regulation as quickly as pos-
sible:
1. Open parameter r12 and stop regulation (in a new appliance not
set previously, r12 will already be set to 0, which means regula-
tion stopped)
2. Open parameter o93 and set the configuration lock to a value of
0 (=OFF)
3. Open parameter 062 = Select a predefined use on the basis
of the electrical connections which appear at the end of the
manual. After configuration of this function, the controller will
shut down and restart.
4. Once the controller has restarted, open parameter 093 and the
configuration lock is opened = value 0.
5. Open parameter r12 and start regulation.
6. When there is a network: set the address for the address switch
in the controller.
7. Send this address to the system unit by activating a service pin.
