Miscellaneous Miscellaneous
Valve and output signal
The controller can control three types of expansion valves - ICM or AKV/A.
With AKV/A up to three EKC 347 controllers can be linked up to a MASTER/SLAVE
function (this function is only used if there is a need for several parallel AKV/A expan-
sion valves). The application is selected with one of the following settings:
1: ICM. AO: 4-20 mA
2: ICM. AO: 0-20 mA
3: AKV/A, AO: 4-20 mA
4: AKV/A, AO: 0-20 mA
or, if the master/slave function is used::
5: AKV/A, MASTER
6: AKV/A, SLAVE 1/1. AO:4-20 mA
7: AKV/A, SLAVE 1/1. AO:0-20 mA
8: AKV/A, SLAVE 1/2. AO:4-20 mA
9: AKV/A, SLAVE 1/2. AO:0-20 mA
10: AKV/A, SLAVE 2/2. AO:4-20 mA
11: AKV/A, SLAVE 2/2. AO:0-20 mA
12: AKV/A, SLAVE 1/1. AO:4-20 mA - AO always updated
13: AKV/A, SLAVE 1/1. AO:0-20 mA- AO always updated
14: AKV/A, SLAVE 1/2. AO:4-20 mA- AO always updated
15: AKV/A, SLAVE 1/2. AO:0-20 mA- AO always updated
16: AKV/A, SLAVE 2/2. AO:4-20 mA- AO always updated
17: AKV/A, SLAVE 2/2. AO:0-20 mA- AO always updated
With settings 1 and 2 the AO [mA] signal is dedicated for the motor valve ICM.
With settings 3, 4, AO [mA] will be send out a signal for process indications.
With settings 6, 7, 8, 9, 10 or 11, AO [mA] on EKC 347 SLAVE, will be send out a signal
for process indications.
With settings 12, 13, 14, 15, 16 or 17, AO will also be updated (active) when DI is OFF

Reference displacement
If you wish to connect a signal that is to displace the controller’s control reference, the
signal must be dened in this menu.
The signal is connected to terminals 19-21 or 20-21
0: No signal
1: 4 - 20 mA
2: 0 - 20 mA
3: 2 - 10 V
4: 0 - 10 V
(The min. value will give no displacement. The max. value will displace the reference
with the value set in menu r06).
o10 o10 AI type
Input signal from the level-measuring unit
The input signal for terminals 14-16 or 15-16 must be dened:
0: No signal
1: Current signal of 4-20 mA
2: Voltage signal. The voltage range must be set in the next two menus. (If the con-
nections are a master/slave system and the signal to the master is 4 to 20 mA, the
setting in the slave modules must also be selected to 1 – this must be done, even if
the signal is connected to the voltage input).
o31 o31 Levelsign.
Voltage signal’s lower value
(only if the setting in 031 = 2).
o32 o32 Lev. V. Low
Voltage signal’s upper value
(only if the setting in o31 = 2)
o33 o33 Lev. V. High
Position signal
If a ICM valve is selected it is possible to have ICM valve position as a [mA] feed back
signal
0: Not used
1: ICM mA feedback signal from connected ICAD.
2: Not used
o34 o34 Valve feedb.
Frequency
Set the net frequency.
o12 o12 50 / 60 Hz
(50=0, 60=1)
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”..
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.
The address is set between 1 and 60 o03 -
The address is sent to the gateway when the menu is set in pos. ON
(The setting will automatically change back to O after a few seconds.)
