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.
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 There are four kinds of settings, ON/OFF settings, settings with a variable value, time settings
and “reset alarms”.
Enter the new value or move the sliding scale up or
down. The new value will apply, when “OK” is pushed.
Set the required value and push
“OK”
Application This menu operation (dated June 2003), applies to controller type AKC 151R, code
number 084B6195 with programme version 1.2x.
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
” has been
selected here.
From the measure line the different
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”.
Function groups
AKC 151R 1.2x Menu operation RC.8B.H1.02 © Danfoss 06/2003 3
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 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 re-
quired 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).
