Miscellaneous
Address
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 madewhen a data communication modulehas 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 0 and 119
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.)
Valve and output signal
Define here the valve that is to regulate and the current signal to be transmitted to
the analog output "AO". The current signal will show the superheat if o17=1. Or open-
ing degree of the valve, if O17=2. Or the S3 temperature if o17=3 0:Off
1: TQ valve and 0-20 mA
2: TQ valve and 4-20 mA
3: AKV valve and 0-20 mA
4: AKV valve and 4-20 mA
5: AKV valve and signal for an other controller. See appendix 3.
Input signal for reference displacement
Definition of function and signal range.
0: No signal
1: Displacement of temperature reference with 0-20 mA
2: Displacement of temperature reference with 4-20 mA
3: Displacement of superheat reference with 0-20 mA
4: Displacement of superheat reference with 4-20 mA
(4 or 0 mA will not give a displacement. 20 mA will displace the reference by the value
set in menu r06)
Frequency
Set the net frequency.
Select signal for showing display
Here you can select the signal to be shown in the normal display.
The signal is also transmitted to the analog output. See O09.
1: Superheat
2: Valve's opening degree
3: Air temperature
(If you during operation give the lower button a brief push, you can see the follow-
ing: The S3 temperature, if 1 has been selected. The superheat reference, if 2 has been
selected. Temperature reference if 3 has been selected).
Manual control of outputs
For service purposes the individual relay outputs and the AKV/A output can be forced
into position ON. However only when regulation has been stopped.
OFF: No override
1: Relay to the solenoid valve is ON.
2: AKV/A output is ON.
3: Alarm relay is activated (connection established between terminals 29 and 31).
Working range for pressure transmitter
Depending on the application a pressure transmitter with a given working range
is used. This working range (say, -1 to 12 bar) must be set in the controller. The min.
value is set.
The max. value is set
(Setting for the function o09)
Set the temperature value or opening degree of the valve where the output signal
must be minimum
(0 or 4 mA)
(Setting for the function o09)
Set the temperature value or opening degree of the valve where the output signal
must be maximum (20 mA). (With a temperature range of 50 K (differential between
the settings in o27 and o28) the dissolution will be better than 0.1 K. With 100 K the
dissolution wil be better than 0.2 K.)

Following installation of a data com-
munication module, the controller can
be operated on a par with the other
controllers in ADAP-KOOL® refrigera-
tion controls.
