ADAP-KOOL® Refrigeration control systems
Menu list This menu function can be used together with system software type AKM. The description is divided
up into function groups that can be displayed on the PC screen. Within each group it is now possible
to show the measured values, or settings. Regarding the use of AKM, reference is made to the AKM
Manual.
Validity This menu operation (from September 2012) applies to controller type AK-LM 330, code Nos
080Z0170 with programme version 1.4x.
Function groups
The operation is divided up into several
function groups. When a selection has been
made, push “OK”, and you may continue to
the next display. By way of example, "Thermostat 1-4" has been selected here.
From the measure line the dierent values can be read. The values are constantly
updated.
In the list of settings the set values can be
seen. If a setting has to be changed, select
the parameter and proceed via “OK”.
Measurements The various measurements can be read directly. If a graphic display of the measurements is required,
up to eight of them can be shown. Select the required measurements and push “Trend”.
Settings Settings can only be made for the daily operation. Conguration settings cannot be seen, changed or
written out. They can only be made from the Service Tool programme.
There are four kinds of settings, ON/OFF settings, settings with a variable value, time settings and
“reset alarms”.
Set the required value and push “OK”

Enter the new value or move the sliding scale up or down.
The new value will apply, when “OK” is pushed.
Go through the individual functions one by one and make the required settings. When settings have
been made for one controller, the set values may be used as a basis in the other controllers of the
same type and with the same software version. Copy the settings by using the copy settings function
in the AKM programme, and adjust subsequently any settings where there are deviations.
NB! If a list is required for noting down the individual settings, a printout can be made of it with
a function in the AKM programme. Read the next section, “Documentation”.
Documentation Documentation of the settings of the individual controllers can be made with the print function in the
AKM programme. Select the controller for which documentation of the settings is required and select
the “Print Settings” function (cf. also the AKM Manual).
Functions Shown below are function groups with corresponding measurements and settings. A printout of the
given settings can be made using the AKM function “Print Settings” (see above).
Note It has been necessary to make a selection from the numerous measurements and settings coming
from the controller.
There is not room for all these in the AKM programme controls.
It can display:
• 8 thermostats
• 2 pressostats
• 2 volt inputs
• 8 digital alarm inputs
• 2 consumption gauges
If it is necessary to obtain access to all measurements and settings, see Using Service Tool, type AK-ST
500.
