How to connect multiple EKE 1C to MMIGRS

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.

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

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

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.

No, only by loading database into a physical unit.

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

1.  Open RMT and select databases per traditional workflow. An Adobe error message will be seen on systems where Flash has been removed
2. Keep the RMT open and note the local host address (seen in website location bar)
3. Open StoreView Desktop and type in the local host address. In this example 'localhost:8080'
4. 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

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

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.

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).

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

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

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.

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

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

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.

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

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.

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

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:

Typical sensor lifespan:

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

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