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 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 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. 6: ICM and ICM
OD% /0-20 mA
7: ICM and ICM OD% /4-20 mA
Input signal for reference displacement
Definition of function and signal range. 0: No signal
1:
Displacement of temperature reference with 0-20 mA
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, 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 12 and 13).
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 and only if the valve is TQ or AKV)
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 and only if the valve is TQ or AKV)
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.)
