Danfoss Menu operation via AKM, Evaporator controller AKC 151R User guide

Brand: Danfoss

Model: Menu operation via AKM, Evaporator controller AKC 151R

Type: User guide

Danfoss Menu operation via AKM, Evaporator controller AKC 151R with software version 1.2x can be used together with system software type AKM. It enables you to control cooling and defrosting processes in refrigeration systems. You can use it to set up and adjust various parameters, such as thermostat cut-out and cut-in values, defrost times and temperatures, and fan operation during defrost. The device also features an alarm system to notify you of any issues or malfunctions.

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).

ON-mode Function of controller outputs when "ON-input" (terminals 32 - 33) and “DI-

input” (terminals 40-41)

“DI-input” controls the forced cooling function. (ON : forced cooling)

(Please note that the ON mode can be overridden from AKM)

0: “ON-input” not active

“DI-input” has priority

“DI-input”= OFF means normal operation

“DI-input” =ON means forced cooling

In other words, if “ON-input”=OFF this always means forced cooling

whatever the “DI-input”

If ”ON-input”=ON

“DI-input”=OFF means normal operation

“DI-input”=ON means forced cooling
