With data communication the impor-
tance of the individual alarms can be
defined. Setting is carried out in the
“ Alarm destinations ” menu.
Miscellaneous Miscellaneous
Choice of application
The controller can be configured in two ways.
The functions for the two applications can be viewed on page 14.
This menu must be set as the first of all menus, as it enables the associated settings to be
set.
1. Show temperature
2: Show pressure
o61 This setting cannot be made via data
communication. It must be set directly
on the controller.
Sensor type
This is where you set which temperature sensor is connected to the Saux input.
The sensor measures the discharge gas temperature in the digital scroll compressor.
1: Built-in NTC sensor in the digital scroll. (A resistor must also be fitted here across
terminals 51-53 in order for the reading to be registered correctly. The resistor ena-
bles the measuring range to be optimised between 80 and 140°C.)
2: Pt 1000 ohm sensor, e.g. AKS 21
o06 Sensor type
Display connection
This is where you define the type of display that is connected to the controller
Off: EKA 164
On: EKA 165. The extended display with LEDs.
o82 DisplaySel
Pressure transmitter’s working range
Depending on the pressure, a pressure transmitter with a given working range is
used. This working range must be set in the controller (e.g.: -1 to 12 bar
The values must be set in bar if display in °C has been selected. And in psig, if °F has
been selected.
If the values are to be set from the
AKM programme, they must be set in
bar.
P0-Min. value o20 P0MinTrsPres
P0-Max. value o21 P0MaxTrsPres
Pc-Min. value o47 PcMinTrsPres
Pc-Max. value o48 PcMaxTrsPres
Use of DI1 input
The digital input can be connected to a contact function, and the contact can now be
used for one of the following functions:
Setting / function:
0
: DI input not used
1: Fan alarm when contact cuts out. Alarm "A34" is given.
2:
Alarm function when the contact cuts out. Alarm “A28” is given.
There is time delay for the alarm. Setting in "A27".
o78 DI1 control
Use of DI4 input
The digital input can be connected to a contact function, and the contact can now be
used for one of the following functions:
Setting / function:
0 : DI input not used
1:
Regulation reference P0 displaced when contact is cut in
2:
Alarm function when the contact cuts out. Alarm “A31” is given. There is no time
delay.
o22 DI4 control
Use of DI5 input
The digital input can be connected to a contact function, and the contact can now be
used for one of the following functions:
Setting / function:
0
: DI input not used
1: Regulation reference Pc displaced when contact is cut in
2:
Alarm function when the contact cuts out. Alarm “A32” is given. There is no time
delay
o37 DI5 control
Operating hours
The operating hours for the compressor relays can be read and set in the follow-
ing menus. The read value is multiplied by 1000 to obtain the number of hours (f.ex.
shows 2.1 for 2100 hours). On reaching 99.9 hours the counter stops and must now be
reset to, say, 0. There will be no alarm or error message for counter overflow.
(In the AKM display the hour number
has not been multiplied)
