Scope

This document is provided with the intent to cover installation and operational actions associated with replacing existing and functioning AK-SC 255 / SM 800 units with AK-SM 800A.
This document assumes the reader has detailed knowledge of Danfoss systems and is qualified for all work activities outlined in this document.
Ground-up commissioning of the AK-SM 800A is not covered by this document, rather the conversion of existing AK-SC 255 units is assumed.

 Key steps and procedures

3.1 AK-SC 255 / SM 800 preparation

warning 2 Before starting any work or removal of systems please alert any remote services that may actively be monitoring the site.

Pre-installation

  • Record and document any current or recently active alarms in the SC255 systems
  • Record and document IP configuration for all units
  • Save history (if required) by using the AKA65
  • Verify all nodes are online
  • Note existing wiring configuration, especially for field bus. Note that the SM800A has x4 TP78 connections
  • Based on customer requirements, note all relevant users and passwords configured in each AK-SC 255, as these, will be required for SM800A 1)
  • Review all AK-SC 255 systems for any points (Relay/Digital/Sensors) with override or offsets applied
  • All AK-SC 255 units must have v2.231 or later. Upgrade all AK-SC 255 if required
  • Save each AK-SC 255 database on a USB flash drive and label it accordingly, this will later be used for the upgrade process.
  • On SM 800 systems, ensure Modbus TCP is set to disable. Failure to have this channel disabled prior to database conversion will affect the network node scan operation of the AK-SM 800A.

3.2 AK-SM 800A pre-flight

warning 2 Tip: Keep the AK-SC 255 systems running until all checks and verifications are complete and the units are ready for a swap over.

Pre-installation

  • Prior to powering up set the host network rotary address switch to match the AK-SC 255 being replaced
  • Power up the AK-SM 800A units and complete the ‘pre-flight’ wizards, this WILL require the use of a new admin user and password 2)
  • As part of the pre-flight wizard, set the time and date and enter the IP addresses used in AK-SC 255 units
  • Complete the pre-flight wizard and set the host address rotary address switch according to the requirements
  • Update software – See appendix for detailed information on updating software on the AK-SM 800A
  • Post Pre-flight (currently logged in), navigate to Configuration renkforce 751624 Weatherproof Code Lock IP65 - WARNING System renkforce 751624 Weatherproof Code Lock IP65 - WARNING Users, and enter all users and passwords per customer specification

  1. It is recommended that strong passwords are used – if original passwords are to be used, the weak password option will need to be enabled on the SM800A Users screen.
  2. It is recommended to keep notes and document this admin user as part of the project documentation. If this code is lost Danfoss is unable to recover and a new password will need to be requested.

3.3 Convert 255 databases to SM800A

warning 2Tip: Check the AK-SM 800A utility screenrenkforce 751624 Weatherproof Code Lock IP65 - WARNING Information for any conversion upgrade issues
Due to differences between controller types some items may not transfer, examples include overrides and offsets.

Pre-installation

  • Save the AK-SC 255 database to a USB flash drive (min v2.231 on AK-SC 255).
  • Insert the above USB Flash drive into AK-SM 800 series (NOT SM800A!) and select database import via the USB Menu.
  • Go to “Menu” (located on a keypad) and select information from the menu. Items not converted will be listed here and requires manual entry.
  • Review the database using AK-SM 800 for any non-typical entries. Names, etc that did not cleanly convert.
  • Save the AK-SM 800 series database to the USB Flash drive.
  • Insert the above flash drive to the AK-SM 800A series and select “import database” under the USB menu option. The AK-SM 800A auto converts the SM800 database,  upon completion, the AK-SM 800A will reset.

Notes:

  • To establish a Host Network connection, go to Utilities and select Ethernet. Select Configuration and select the “Initialize” option.
  • If an SM800A host network is being used, make sure all units have common user-level access and passwords applied. This will ensure full visibility when connecting with StoreView Browser.

Danfoss AK SM 800A System Manager - Fig4

Software update

Software update function – an introduction
Like many other modern electronic devices, it is important that you maintain your AK-SM 800A with up-to-date software. Danfoss has a policy of continuous improvement and enhancement and will regularly offer updates to your system. These updates will include bug fixes, new enhancements, and important updates for security vulnerabilities.  Updates can be categorized as ‘recommended’ or ‘mandatory’, with supporting documentation describing the categorization. The following section describes the Software  Upgrade feature, found in the utility app. Use this feature to remotely update your AK-SM 800A series controller.

Operational scope and Important notes:
Once connected to your AK-SM 800A series controller you will have access to the Utilities App. The Software Upgrade function is currently designed for single SM800A units only. For example, if you have a host network of multiple units, ensure you connect to the actual unit (IP address) that you intended to update. To update other units on the host  network, be sure to log into that unit’s unique IP address and follow the same workflow

The software packages available for your AK-SM 800A have unique assigned ‘digital signatures’, this signature is then validated by the AK-SM 800A to ensure the file has not been altered or tampered with. Any software package that is modified will be rejected by the AK-SM 800A and updates will not be possible
Important:

  • Whilst upgrading your system, power must not be interrupted at any time during the update process. Any power loss during the update procedure may cause permanent damage or corruption to your AK-SM 800A series.
  • In host network applications (multiple interconnected AK-SM 800A units) it is required that ALL units have the same software installed. Failure to do so may result in unexpected behavior and may affect the control and monitoring of your store.

Note: To download the latest software package for your AK-SM 800A series controller, visit http://www.ak-sm800a.danfoss.com/

Utilities – Software update function
The software update utility offers two methods of updating, Local Stored File and Web Connectivity (note, in addition to using the Utilities, any of the USB ports on your AK- SM 800A can also be used to update software via a flash memory stick).
Local Stored File: This method assumes you have previously downloaded a software package from http://www.ak-sm800a.danfoss.com/ and this package is located on the device you are using to access your AK-SM 800A / SvB5.

  • Click on the Local Stored File option and select the software package via the ‘Choose File’ button.
    The file type is SPK (Software Package)
  • Press the Upgrade SM800A button to initiate the package download to the SM800A
  • After the package has been downloaded and checked for integrity, press the install button to execute the update. Note: During the update process, your AK-SM 800A will reset, this will temporarily disconnect your connection. Press the browser refresh to reconnect after ~3 minutes.
  • An upgrade Log will appear, with the final status ‘Software upgrade SUCCESSFUL!’, press the Home button to get back to the Utilities.

Web Connectivity: This method assumes you have connected to your AK-SM 800A via a device that has access to the Internet. Selecting this option will use your Internet connection to retrieve the latest AK-SM 800A software package (from the secure Danfoss software server) and with the live browser connection to the AK-SM 800A unit, will update the software. Follow the screen prompts to perform a software update via a web-connected device. (NOTE: At this time Apple® based platform(s) do not support the web connectivity function, if using an Apple® device, use the Locally stored file option described above).

Operating System (Linux)
This function follows the same principle as described above for software updates but is supporting the updating of the System Managers operating system (OS). Your AK-SM  800A utilizes a Linux-based distribution, specifically for Danfoss and like all software systems, updates may be required for feature or security reasons.
