FAQ

Find answers to your frequently asked questions...

System Manager General

Are spare parts available for system managers?

No. If controller is defective, full unit should be replaced.

Can I use a volt meter on the comm loop to help identify communication issues?

No, only an oscilloscope will supply proper information showing the quality of the signal on the comm loop.

Can different models of system manager communicate on a common network?

No, system managers can only communicate to same series type. For example, AK-SM 800A cannot communicate with AK-SM800.

Is the AK-XM 208C module compatible with my system manager?

AK-XM 208C is only compatible with AK-SM 800A series running software v4.0 or newer.

What are edf, ed3, and epk files?

These are files that allow the system manager to properly display data from generic devices types such as pack controllers, case controllers, and 3rd party devices. Each device type has a dedicated file, and each file type is used with a specific model of system manager (edf = AK-SC 255, ed3 = AK-SM 800, epk = AK-SM 800A).

What should I do when my system manager’s offline alarm is triggered?

Perform a rescan at the system manager, which will force the controller to scan for the offline devices. If that doesn’t solve the problem, perform secondary checks, including proper EOL termination of the loop and power at the offline devices.

AK-SM 800A

What should I do if I do not know my AK-SM 800A username or password?

Press “Forgot Credentials” from the login screen, and then “Reset Password”. This will give you a MAC Address and code. Then, call Danfoss monitoring at 1-866-513-0581 with these details to obtain temporary login credentials.

Can an AK-SM 800A database be viewed offline?

No, only by loading database into a physical unit.

I’m replacing an AK-SC 255 with an AK-SM 800A. Which part number should I use when ordering?

Part number 080Z4029 is the retrofit version of the AK-SM 880, with native LONTP78 communication. Additional part numbers can be found here.

AK-SM 800

What's an Adobe Flash workaround for RMT offline simulation?

Open RMT and select databases per traditional workflow. An Adobe error message will be seen on systems where Flash has been removed
Keep the RMT open and note the local host address (seen in website location bar)
Open StoreView Desktop and type in the local host address. In this example 'localhost:8080'
Click the "connect" button and StoreView Desktop will present the login screen for that database

Notes:

By running the RMT tool, the simulation 'engine' is open in the background and StoreView Desktop then takes the role of the browser
New databases can be created using this workaround and saving via the "Configuration >> Save Database" menu

AK-CC Case Controllers

How do I configure a new AK-CC 210?

Watch our video for an introduction to AK-CC 210 functionality.

My case controller has three icons flashing on the left side of the display. What does this mean?

Flashing icons indicate an alarm condition. For details on what the alarm indicates, press the top button of the case controller for the alarm code. Additional details can be found on the KoolCode app or in paperwork included with the case controller.

I just installed a new case controller and it will not call for refrigeration. What’s causing this?

Think of parameter r12 as the main switch for case control, so it needs to be set to the “On” position before operation will begin (when set to “Off,” alarm code A45 will be active).

What does Po sensor error alarm mean?

This alarm indicates that the suction transducer is reading outside of the normal range. Wiring and programming of the transducer should be checked.

My case controller shows “-d-“ on the display but is not defrosting. What does this mean?

The case controller will continue to display this during the pulldown phase until the case has reached its cut-in temperature.

How do I set the address in a case controller (including AK-CC 210, 525A, 550A, and EKC 202D2)?

Press and hold the top button for 5 seconds or until r01 is displayed. Next, use the top button to navigate to “o03.” Then, press the “Set” button and change address from 000 to desired address using top button. When complete, press “Set” button again.

AK-SC 255

Can the AK-SC 255 communicate with all AK2-style of IO?

Yes, however for the AK-XM 103A (4AI/4AO) module, firmware version v2.101 or higher must exist in the controller.

How can I direct connect to an AK-SC 255?

Direct connect can either take place through a 9-pin to RJ45 connector, or via cat5 cable using the process found here.

What should I do if my AK-SC 255 loses its license?

You will need to contact Danfoss tech support to obtain the original license, which can be re-entered into the Configuration->Licensing screen of the controller. Note a lost license does not result in lost control, only loss of ability to make programming changes.

Leak Detection

How to start up with the DGS Gas Detector?

This guide describes step by step how to quickly set up the DGS Gas Detector.

Download the complete guide

Can I ask for the calibration certificate?

The sensor calibration certificate is normally included in the installation pack.

If you lose this certificate, you can request it from your sales representative by providing:

Code number, Serial Number and Manufactured date printed on the sensor head.

How often does the sensor need to be re-calibrated?

When the DGS is provided, the sensor is already calibrated from the factory side.

The sensor has then to be re-calibrated depending on the gas used in the application.

Following the period recorded in the sensor head:

60 months for CO2 infrared sensor
12 months for HFC semiconductor sensor
6 months for Propane pellistor sensor

When the calibration period expires, may I then re-calibrate the sensor?

Yes, when the calibration expires there are 2 possible options:

Replace the sensor head
Re-calibrate the sensor. This operation resets the calibration period counter recorded in the sensor head.
Link to calibration guide
For the re-calibration procedure, please take a look at the below video:

How do I gain calibrate the DGS?

In this video, we will see how to gain calibrate the DGS.

How do I zero calibrate the DGS?

In this video, we will see how to make zero calibration in the DGS.

What is the life expectancy for the DGS sensor?

Typical sensor lifespan:

Infrared (CO₂) – 5-7 years
Electrochemical (NH3) – 2-3 years
Semiconductor (refrigerants) – 5-7 years

Is the DGS for propane sensor ATEX approved?

No, the DGS for propane can only be used in a non-ATEX zone.

Storeview Web

How do I access to Storeview Web?

Browser-based access
Go to svw.danfoss.com on your browser and login with your usual information, See below for common issues when connecting
Desktop based access:

A desktop application will be available for download very soon, in the meantime you can save the app for offline use in your browser, see instructions below.

Do I need to sign up for Storeview Web?

No, you log in with the user profile you have created for your AK-SM 800A, along with the IP address of the unit. Note: It is only possible to access Storeview Web if you have access to a connected AK-SM 800A or AK-SM 800.

Which browsers are supported?

Most modern browsers are supported, e.g. Microsoft Edge, Google Chrome, Firefox and Safari. Internet Explorer is not supported as it has reached end-of-life.
We continuously update SvW and actively maintain support for the last 6 months of updates of the browsers.

Note: Edge and Chrome are both case on the Chromium browser engine, which from version 94 and above restricts how you can access private systems. See x) Common issues when connecting, if you experience problems.

Note: We also offer PWA versions of Storeview Web, see the x) How to save SvW for offline use

I cannot access HTTP version of Storeview Web

Many browsers are blocking access to HTTP sites, in Chrome you manually change the settings by following these step and “allow” for insecure content. As an alternative we recommend to use the Desktop version of Storeview Web.

Which operating systems are supported?

For now, SvW Desktop only supports Microsoft Windows version 7, 10 and 11. We are working on adding support for MacOS and certain Linux distributions in addition to docker support.
Note: We also offer PWA versions of Storeview Web, see the x) How to save SvW for offline use

Which hardware is supported?

AK-SM800 from version G08.045 and AK-SM800A all versions.

I get a warning and I cannot connect to my system?

See x) Common issues when connecting

Common issues when connecting

a. I have trouble connecting to my HTTPS enabled system-manager
You might see a warning when you try and connect to a HTTPS enabled system, mentioning that SvW could not reach the target system and that you might need to manually trust the certificate of the system. This warning can also be shown if the target system is offline or unavailable.

The AK-SM800A is loaded with a self-signed certificate from the factory, self-signed certificates are untrusted and as such requires manual validation by the end-user. The AK-SM800A user guide explains how to install a trusted certificate which allows you to skip this warning. Remember that if you are using a multi-system site, all certificates needs to be trusted. If that is the case, you will see a yellow warning triangle when logged in, which will prompt you to accept all certificates for all units in the system.

b. I have trouble connecting to my HTTP enabled system-manager
There are special considerations to be made when using a HTTP enabled system. HTTP connections are slowly being deprecated in favor of HTTPS which means that many browsers and operating system are slowly increasing the restrictions placed on those systems. This can impact SvW’s ability to communicate with the system-manager.

Most importantly a security mechanism called Cross-Origin Resource Sharing, or CORS, has recently been introduced to Chromium based browser from version 94 and above (See link for more details). CORS is a mechanism that’s intended to protect the end-user from malicious websites who would have been able to interact with private systems (I.e. your home router) using a cross-origin request. In other words, CORS prevents a public system, like svw.danfoss.com, from interacting with private systems like your system manager.

CORS takes effect when any public system, loaded over insecure HTTP, tries to interact with a system on a private network. Private networks are defined as any IP’s in the following subnets 10.0.0.0/8, 172.16.0.0/12 or 192.168.0.0/16.

This means that you will likely experience an inability to connect to an HTTP configured AK-SM800 system if your browser is either Edge or Chrome above version 94.

If you do experience problems, then we advise you to download and use the desktop version instead, or to use Firefox which is not yet affected, or to contact your Corporate IT department who can disable these security policies using a group policy.

c. I have other problems connecting to my system
Please reach out to your local representative and include details about your setup including; Browser Type and Version, IP settings of target system, Use of VPN if applicable, etc., please also include a system-report from the target system if possible.

d. Important differences between the different HW and FW versions:

AK-SM800 FW G080.045 and above: This device does not support HTTPS and does not support CORS security
AK-SM800A FW 3.0 and below: This device supports HTTPS but doe not support CORS security
AK-SM800A FW 3.0 to 3.2: This device supports HTTPS and has support for CORS security
AK-SM800A FW 3.2: This device supports HTTPS, Strict CORS and has support for header-based authentication

I am using a VPN or a proxy, Can I connect?

Yes you can, but it depends entirely on the configuration and type of VPN or Proxy. Most importantly, your device should be able to access the target device. You can check if you have access by going to the domain address or IP of the target device. If the browser does not timeout, but loads a page then you can connect using SvW. If the browser times out or if no page are shown, then you will likely not be able to use SvW.

How to save SvW for offline use

SvW can be installed as an offline PWA app on most devices. The feature is dependent on you OS and Browser type and version. If you don’t see the options mentioned below, then your device might not be supported.

Note: Installing a PWA application is only possible on the HTTPS version of SvW. Most browsers do not allow HTTP install. Once the application is installed, you can switch to HTTP mode within the application.
