1.0 Scope

2.0 Introduction to AK-SM 800A / Comparison to AK-SC 255

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.

3.0 Key steps and procedures

3.1 AK-SC 255 / SM 800 preparation

3.2 AK-SM 800A pre-ﬂight

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 on-line

• 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 SM800A1)

• 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 accordingly, this will later be used for the upgrade process.

• On SM 800 systems, ensure Modbus TCP is set to disabled. Failure to have this channel disabled prior to database conversion will eﬀect the network node scan operation of the AK-SM 800A.

Tip: Keep the AK-SC 255 systems running until all checks and veriﬁcations are complete and the

units are ready for swap over.

Pre-installation

• Prior to power 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

• As part of the pre-ﬂight wizard, set time and date and enter in the IP addresses used in AK-SC 255 units

• Complete the pre-ﬂight wizard and set the host address rotary address switch according to 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  System  Users and enter all users and passwords per customer speciﬁcation

Pre-ﬂight wizard

It is recommended that strong passwords are used – if original passwords are to be used, the weak password

option will need to be enabled in the SM800A Users screen.

It is recommended to keep note 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 database to SM800A

Tip: Check the AK-SM 800A utilities screen  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 above USB Flash drive into AK-SM 800 series (NOT SM800A!) and select database import via the USB Menu.

• Go to “Menu” (located on keypad) and select information from the menu. Items not converted will be listed here and requires manual entry.

•

Review 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 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 Host Network connection, go to Utilities and select Ethernet. Select Conﬁguration and select the “Initialize” option.

• If a 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.

6.0 Appendix

7.0 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 continued 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 utilities 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 units 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 be altered or tampered with. Any software package that is modiﬁed will be rejected by the AK-SM 800A and update 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 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

Application Guide | AK-SC 255 / SM 800 to AK-SM 800A conversion

)

Future use

• 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 secure Danfoss software server) and with the live browser connection to the AK-SM 800A unit, will update software. Follow the screen prompts to perform a software update via a web connected device. (NOTE: At this time Apple® based platfrom(s) do not support the web connectivity function, if using an Apple® device, use the Local stored ﬁle option described above).

Operating System (Danux)

This function follows the same principle as described above for software update, 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.
