FAQ

Find answers to your frequently asked questions...

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.

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

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.

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.

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

Part number 080Z4009 is the retrofit version of the AK-SM 880, with native LONTP78 communication. Additional part numbers can be found here.

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).

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.

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.
