Danfoss EKC 361 User Manual page 6

Actuator type
Here you define the actuator mounted in the system:
1: CVQ -1-5 bar
2: CVQ 0-6 bar
3: CVQ 1.7-8 bar
4: CVMQ
5: KVQ
6: ICM
P: Amplification factor Kp
If the Kp value is reduced the regulation becomes slower.
I: Integration time Tn
The I-setting can be cancelled by setting the value to max. (600s). If it is set to 600s, parameter
n07 must be set to "0". (If the Tn value is increased the regulation becomes slower).
D: Differentiation time Td
The D-setting can be cancelled by setting the value to min. (0).
Transient phenomenon
If the refrigeration requires a very fast transient phenomenon or must not have an underswing or
temperature shift, this function can be used. (see page 4)
0: Ordinary regulating technique
1: Fast building-up where a minor underswing is allowed
2: Not quite so fast building-up, but without underswing
OD - Opening degree Max. Limitation - ICM only
When ICM has been selected (n03=6) the Maximum OD can be entered. ICM will never go above
this value. (If n32=n33, ICM is forced to this value)
OD - Opening degree Min. Limitation - ICM only
When ICM has been selected (n03=6) the Minimum OD can be entered. ICM will never go below
this value. (If n32=n33, ICM is forced to this value)
Miscellaneous
Output signal
The controller can transmit a current signal via the analog output (terminal 2 and 5). Range of
current signal can be selected below:
If (017=Air) Sair will send out to the analog output.
If (017=Au) Saux will send out to the analog output
S /S min. value (0 or 4 mA) will correspond to the setting in "o27"
air aux
S /S max. value (20 mA) will correspond to the setting in "o28"
air aux
If ICM has been selected (n03=6)
OD (u24) to control ICM, is send out to the analog output
(o27) and (o28) is not active
Range for current signal:
0: No output signal
1: 4-20 mA
2: 0-20 mA
Input signal
If you wish to connect a signal that is to displace the controller's control reference, the signal
must be defined in this menu.
0: No signal
1: 4-20 mA
2: 0-20 mA
(4 or 0 mA will not give a displacement. 20 mA will displace the reference by the value set in
menu r06).
Data communication
If the controller is built into a network with data communication, it must have an address, and
the master gateway of the data communication must then know this address.
These settings can only be made when a data communication module has been mounted in the
controller and the installation of the data communication cable has been completed.
This installation is mentioned in a separate document "RC8AC".
The address is set between 1 and 60
The address is sent to the gateway when the menu is set in pos. ON
(The setting will automatically change back to Off after a few seconds.)
Language
This setting is only required if data communication is connected to the controller.
Settings: 0=English, 1=German, 2=French, 3=Danish, 4=Spanish and 6=Swedish
When the controller is operated via data communication, the texts in the right-hand column will
be shown in the selected language.
When you change the setting to an other language you must activate o04 before "the new
language" can be visible from the AKM program.
Frequency
Set the net frequency.
