2.2 Preparing for replacement

When replacing, you have to use the following new parts:

• CPU module

• SD card

• Flat cable, if necessary (for wiring box)

• Stand-alone software

2.3 CPU module type

There are two types of CPU modules. An old ARM type and a new IMX type. This affects the way data is saved

on the module.

Check whether the module to be replaced is an ARM or IMX type.

ARM based CPU module (one LAN port) IMX based CPU module (two LAN ports)

This CPU module will automatically save all his-

torical data to the SD card, regardless of how

menu settings have been made.

This CPU module will automatically save all his-

torical data to the internal memory and only use

the SD card as backup media.

2.4 Backup of existing setup and data

SKOV A/S recommend that backup of historical data is set to take place automatically once a day. This ensures

that a new backup will always be available. The automatic backup takes place at 1:30 a.m.

Although the house controller is set to backup automatically, it can be an advantage to make a new backup just

before the replacement is carried out. This ensures that the latest data is transferred.

Make a note of the main module and CAN protocol setup in the menu | Technical | Installation | Man-

ual installation | I/O modules.

If necessary, take photos of the pages and the installation menu Show connection ( | Technical | Instal-

lation | Show connection).

Note or take pictures of the values of the following settings (*If installed).

Technical User Guide 7

Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-

fied personnel in compliance with the applicable national and international standard EN 60204-1

and any other EU standards that are applicable in Europe.

The installation of a power supply isolator is required for each motor and power supply to facilitate

voltage-free work on the electrical equipment. The power supply isolator is not included.

2.5 Replacing CPU module incl. display

1. Disconnect the power to the controller.

2. Disconnect the network connector from the CPU module, if your controller is part of a network.

3. Remove the flat cable (B) from the main module.

4. Loosen the six screws (C) and remove the CPU module incl. display (D).

5. Mount the new CPU module incl. display (E) by means of the six screws and connect the flat cable on the

main module (B). Do not remove protective grating.

6. Connect the network connector if your climate controller is part of a network.

7. Power the controller.

2.6 Replacing the power supply

Check if the power supply needs replacement.

If the power supply in the controller has a label with the text "Power Supply SMPS 24v 2.1 A-Type: 290035” or

”Power Supply SMPS 24V 2.1A - Type: 290036” or ”Alpha Power module 3.2 A – Type 292620”, the power sup-

ply does not need to be replaced.

If there is a different type in the controller, the power supply needs to be replaced with either 135750 Power

Supply 24 V 2.1 A or 135703 Power Supply 24 V 3A. The power supply must be ordered separately.

2.7 Replacing flat cable (only with wiring box)

If the CPU module in a wiring box solution needs replacement, the factory-installed flat cable typically is not long

enough and should therefore be replaced by a longer one.

Release the display from the CPU module. Use a

screwdriver to lift the display so that the flat cable

can be detached.

Please note:

You only have to actuate the two front taps, so that

the display remains mounted and the flat cables

connecting the display with the PCB are not af-

fected.

Lift the flat cable and disconnect the cable.

Avoid pulling the flat cable.

Insert the long flat cable.

Click the display onto the CPU module again. Use a

screwdriver.

3 Installation guide

3.1 Loading of stand-alone software

The CPU module comes with basic software. The required stand-alone software must be loaded when the con-

troller starts up.

There are two procedures for loading of stand-alone software:

Allow the controller to find the stand-alone-software automatically (A. Automatic loading of stand-alone software

(recommended) [}9]).

Select the stand-alone software manually from a list (B. Manual selection of stand-alone software [}9]).

3.1.1 A. Automatic loading of stand-alone software (recommended)

This procedure may only be used when the existing setup or backup has been saved to an SD card or when a

USB stick with a previously saved setup or backup from the controller exists. See also the section Backup of ex-

isting setup and data [}5].

The procedure ensures that the same stand-alone software is reloaded on the controller.

(C)

(B)

(A)

(A) Use the menu Find system from SD backup to locate the

variant on a SD card with backup.

(B) Use the menu Find system from USB backup to locate

the variant from a USB stick with backup.

the variant from a USB stick where settings have been saved.

The controller will restart while loading.

3.1.2 B. Manual selection of stand-alone software

It is important to select the correct stand-alone software in order to ensure that the required functions are avail-

able in the controller.

Note: This menu is only available in a spare part!

Note: It is NOT possible to change the stand-alone software to another variant once it has been selected. Infor-

mation on the controller’s variant can be seen on a label located on the inside of the front panel or on the side of

the cabinet.

(D)

(D) To select the stand-alone software manually, use the menu

Select system from variant list.

10 Technical User Guide

The menu displays a list of the various stand-alone software

variants.

Be careful to select the right version.

The controller will restart while loading.

Do not remove the USB stick/SD card until the graphical user

interface is accessible again.

Loading completed successfully.

It is VERY important not to interrupt the power supply while loading the stand-alone software.

3.2 UTC time

The controller uses two different time settings. A user-selectable local time (menu button | Settings | System |

Adjust date and time) and the so-called UTC time (Coordinate Universal Time), which is the internal time in the

controller, for example, used for time-stamping of alarms. However, the time viewed by the user is always the

local time.

For controllers in a network, the management program FarmOnline Explorer will automatically make sure the

UCT time is correct.

As for controllers not in a network or without access to an NTP

(Network Time Protocol) server, the UTC time can be adjusted

in the menu Technical | Service | UTC time.

UTC is a default setting and both time settings of the controller

are supported by a battery backup function. The UTC time thus

only needs to be set in those cases where the climate con-

trollers have been without battery backup.

Find the current UTC time, for example on the website

http://www.timeanddate.com/worldclock

3.3 Checking CAN protocol setup

The CPU modules come with CAN protocol set to CANopen. It may therefore be necessary to change the set-

ting depending on the type of I/O modules or silo weighing boxes of the controller.

Select the menu | Technical | Installation | Manual in-

stallation | Protocol

If CAN protocol is not indicated on the main I/O module or addi-

tional I/O modules, the CAN protocol must be changed to Clas-

sic.

3.4 Main I/O configuration

The main I/O can be set up with a different number of inputs and outputs.

Replacement of 7” CPU Module incl. Display

Technical User Guide 11

Select the menu Technical | Installation | Manual in-

stallation | Main I/O module.

Set Main I/O module to match the original setting.

3.5 Adjust time and date settings

The CPU module time and date settings must be adjusted to current time.

1. Select the menu |System |Adjust date and time

2. Adjust time and date.

3. Select the menu | Service | UTC-time

4. Adjust time and date.

3.6 Import data from replaced controller

This function may only be used when replacing a house controller or parts of it, as the function

copies the IP address, house name, historical data, calibration values, etc.

In order to prevent data loss when replacing a defective house controller or individual hardware parts, it is possi-

ble to import all types of data from the SD card.

The SD card should contain data that has been saved manually or by daily backup.

Save Copies data and setup of pages from the controller to the SD card.

Load Loads data and setup of pages from the SD card to the controller.

Backup Make a backup of all controller data. Data comprises settings, pages, calibration

values, etc.

Restore When data from an SD card is restored in a replaced house controller, the existing

setup is fully restored, complete with calibration values and pages. All historical

data such as silo status and number of animals is also imported.

Daily backup Activate the function to make a daily backup of data from the controller.

Format SD card Delete all data from the mounted SD card.

SD card status See the status of the SD card. The status must be Mounted when importing data.

1. Insert the SD card from the old CPU module into the new CPU module.

2. Select the menu Technical | Service | SD card | Restore.

3. Confirm the restore.

4. Wait for the house controller to restart automatically.

5. Disconnect the power to the controller.

6. Connect the power to the controller again.

Steps 5) and 6) are necessary in order to ensure that both the controller and all components/sensors are config-

ured and function as expected.

Replacement of 7” CPU Module incl. Display

12 Technical User Guide

Once the restore is complete, it is recommended that you remove the old SD card and mount the SD card that

came with the new CPU module instead.

This is done because the previous backup uses a large amount of memory on the previous SD card and pre-

vents a new backup being made.

Another option is to format the previous SD card in order to free up its memory.

Select Format SD card in the menu Technical | Service | SD card.

SKOV A/S recommend that the controller is set up to make automatic daily backups of historical data (in the

menu Technical | Service | SD card | Daily backup).
