Necessary connections (fig. 4, 5 and 6)
Terminals:
28-29 Supply voltage 24 V a.c. or d.c.
1-7 Signal from level transmitter type
AKS 4100/4100U or
7-10 Signal from level transmitter type
AKS 41
36-37 Expansion valve type AKV or AKVA
(see note to the right) or
23-24 Expansion valve type: ICM with
ICAD
13-14 Switch function for start/stop of
controller. If a switch is
not connected, terminals 13 and 14
must be shortcircuited.

Application dependent connections
(fig. 4, 5 and 6)
Terminals:
33-35 Relay for common alarm.
Installer can choose between
ICAD Normally Open (33-34) or Normally
Low Closed (34-35) circuits.
AKS 4100 The relay will switch according to
the programmed setting.
25-27 Relay for low level limit.
Installer can choose between
AKV/A Normally Open (26-27) or Normally
Low Closed (25-26) circuits.
AKS 4100 The relay will switch when the set
value is passed.
30-32 Relay for upper level limit.
Installer can choose between
AKV/A Normally Open (30-31) or Normally
Low Closed (31-32) circuits.
AKS 4100 The relay will switch when the set
value is passed.
6-10 ICM valve feedback signal from
ICAD 0/4-20 mA
AKV/A
High Note!
AKS 4100 If AKV(A) is used, the power supply
must cover the AKV(A) coil wattage
additionally (see fig. 5).
AKV(A) Coil voltage must be the
same as controller supply voltage
AC or DC.
MASTER/SLAVE and I/O configuration
(fig. 7b and 7c)
When more controllers are connected via
CAN bus each end of the bus must be ter-
minated with a jumper between 15 and 16.

Control Panel (fig. 8)
The user interface of the control panel con-
sists of a multiline display and 4 individual
push buttons: Enter button, Page up
button, Page down button and Back
button.
Fig. 8 shows the Home display image,
which give the actual overview. This is the
starting point for entering into menus, and
you will revert to this image by pushing
1 – 3 times (depending on actual position).
Display (fig. 9)
The display itself show the state of Liquid
level, Controller Mode (controller On/
Off), Valve opening degree, Lower level
alarm (on = no alarm present) and Upper
level alarm (off = no alarm present).
Additional to the external connected alarm
audio/video sources, a Bell symbol will
flash in the upper right corner in case of an
alarm.
To see more details on system perfor-
mance and setting of parameters, 2
different main menu levels can be reached
by operation of the push buttons.
