Alarm notice
Alarm acknowledgement: press
the OK button. The beeper will be
turned o. If the cause of the failure
is not fixed, the exclamation mark in
the upper right corner of the display
will keep blinking.
The Ouman Ouflex M BA controller may emit alarms when digital inputs are
triggered. Alarm details are highlighted on the screen in failure mode, and the
beeper sounds.
When there are more than one unacknoledged alarms in the controller, information
on the most recent alarm is highlighted on the screen. After all active alarms are
acknowledged, the display quits the failure highlight mode and the beeper stops.
The beeper can be turned o with active alarms present by pressing the ESC
button. When you do so the window with details of the most recent alarm on the
screen will close.
To view active alarms, go into the menu
"Alarms → Active alarms". Uncleared alarms are marked with an exclamation mark
at the start of the line.
Some of the information in your Ouflex M BA device may be hidden. You
can see the hidden menus by pressing OK for a few of seconds. Similar-
ly, you can hide them again by pressing OK for a few of seconds. Hiding
information that you seldom need to change or look into makes the UI
simpler. When visible, this information is shown indented.
There may be a maintenance code in use in your Ouflex M BA device.
In this case, you can see the information even when it’s locked, but you
can’t make changes to settings without entering the maintenance code.
Normally, you lock the most critical settings behind the maintenance
code, or settings that require expertise.
There is a symbol in front of a setting that requires maintenance
code.

Test the SMS communication. Send a message to Ouflex M BA:
Keywords. If the controller replies with a message containing a list of
key words, text message communication is ok. If the controller doesn’t
reply, switch power o and on again. You can check the validity of the
subscription using a mobile phone. Insert the SIM card in a mobile pho-
ne, send a text message to another phone and reply. If the messages go
through, the subscription is OK. Insert the SIM card back to the GSM mo-
dem and test SMS communication again. If controller still does not reply,
check that the message center number has not been inserted manually.
Press OK button for a few seconds to display hidden menus. Remove
message center number: clear the first digit and press OK button for a
few seconds. Switch power o and back on. Controller retrieves the mes-
sage center number automatically (the message center number is not
visible on the display).
7. Retest the text message communication.
When Ouflex M BA device starts up, it will automatically detect whether the
modem is connected or not and then initialises modem.

There are two alternative ways to set the Ouflex M BA device IP ad-
dress and network settings:
1. IP address is retrieved via DHCP function. This requires that
DHCP service is in use in the network and network cables have
been connected.
2. IP address is set manually.
1. Request correct network settings (IP address, Gateway address,
Subnet mask, Nameserver address) from the network administra-
tor.
2. Go to “System settings” -> “Network settings” -> “DHCP” and
press OK.
3. Select ”O” and press OK to accept selection.
4. Enter all network settings (IP address, Gateway address, Subnet
mask, Nameserver address) provided by the network administra-
tor.
5. Select ”Update network settings” .
System settings > Network settings
The Ouman Access service (M-Link device) can be purchased from
Ouman. It oers a secured connection to automation equipment
using an existing internet connection. If an internet connection is
not available, it is possible to use a 3G-MOD4 modem, for example, to
establish a ready-to-use connection to the subject.
Network settings
1. Go to DHCP and press OK.
2. Select ”On” and press OK to accept selection.
3. Select ”Update network settings” and press OK to accept selec-
tion.
4. Wait approximately one minute.
5. The network settings are now assigned to Ouex M BA by DHCP
server (new settings should appear automatically in the user in-
terface)
Otherwise check the network connections and ensure that
DHCP-server is available in the network.

1.3 Network settings
If you want to connect the Ouflex M BA unit to an Ethernet net-
work, you will need an M-Link adapter (additional equipment).
M-Link is connected to COM3 port (RJ45) located in the side of the
controller. The maximum length of the RJ45 ethernet cable bet-
ween Ouflex M BA and M-Link is 10m and all 4 pairs must be con-
nected. If you have changed your network settings, select ”Update
Network Settings”.

Modbus TCP/IP port (internal registers): Port number 502 is reser-
ved for communication of Ouflex M BA device. Information of Modbus
registers of Ouflex M BA device are read and written through this port.
Max connections: It is possible to decrease server load by changing
this setting that defines the maximum number of simultaneous con-
nections from dierent IP addresses to the server.
Idle timeout: This setting defines the time after which the server clo-
ses an inactive connection.
Allowed address: It is possible to improve the information security
of the system by taking permitted connection address into use. If the
value is 0.0.0.0, connections to the server are permitted from any IP
address. If you define one permitted connection address, connections
to the server are not permitted from any other IP address.
Function on: This selection either enables or disables the Modbus/
TCP communication.
Modbus TCP/IP gateway →Modbus 1 port: It is possible to connect a
Modbus/RTU bus to Ouflex M BA controller. The bus has its own port
address that is used to communicate with bus devices via Modbus/
TCP interface. Port 1 setting defines the TCP/IP port that functions as
a gateway to Modbus RTU-bus.
System settings → Network settings → Modbus RTU slave
Ouflex M BA unit can be connected to a Modbus RTU as a slave de-
vice. The first row shows to which bus Ouflex M BA is connected as
a slave device. Set Ouflex M BA bus address. Note. Two devices may
not have the same bus address. All devices in the bus should be set to
the same setting value of the baud rate, data bits, stopbits and parity.
System settings > Network settings→Modbus TCP/IP
If the Ouman Access is taken into use, the sent SNMP alarm mes-
sage will include the Access IP-address. In this case, Access IP
address must be entered as local IP-address in Ounet.
SNMP: SNMP function can be used to send notifications about alarms
activating, inactivating and being acknowledged via SNMP protocol
to a desired server.
IP address: The IP address of the target server to which messages are
sent. Ounet IP address is a default.
Active: This selection either enables or disables the entire SNMP fun-
ction.
System settings > Network settings→ SNMP
System settings → Network settings → Modbus RTU master
Ouflex M BA device can be a master device in two Modbus RTU. It
is shown in the first line in which the bus Ouflex M BA is the master
device. All the devices in the same bus should be set to the same set-
ting value of the baud rate, data bits, stopbits and parity. If a device is
unstable on the bus, it may be possible to get the bus trac stable by
increasing the delay between the packets.

Do backup
Create a backup, when Ouflex M BA has been configured and the de-
vice-specific settings have been set.
If desired, the original application’s setting values, time programs
and naming can be restored to the device.
All the parameters which are saved in the non-volatile memory will
be included in the backup. Such parameters are e.g. all the setting
values and time programs. The backup can be saved to the internal
memory or to micro SD memory card. Memory card backups can be
copied from one device to another.
Memory card is not included in the delivery.Technical requirements to mi-
croSD memory card:
Standard micro SDHC, UHS
Capacity 512 MB...32 GB
File system FAT 32
Class: 4...10+
Restore backup
If you created a backup, you can restore the backup by pressing OK.
You can restore the backup from the memory card (device external
memory) or from the internal memory.
Software updates
It is recommended to create a backup of the system before software
update. The software update is done with following steps:
1. Remove microSD memory card from Ouflex M BA.
2. Insert new microSD memory card which includes new software to
Ouflex M BA.
3. Ouflex M BA asks: ”Would you like to restart device?”
4. Select: ”Yes”
5. Ouflex M BA reboot to start the update of the new software. The up-
dating of the software takes few minutes.
