Wireless transmission of 4-20 mA signals from a measurement location to
the control centre, typical applications are industrial process automisation,
evaluation of all kinds of 4-20 mA sensors for temperature, humidity, filling
level etc. in the chemical industry.
Wide fields of applications exist for remote transfer of liquid levels of all tank
probes in common use to a centralised control station, integration of overfill
prevention systems into fuelling systems for automotive fuelling, harbour
terminals, railway tankers and aeroplane fuelling systems.
Special “barriers“ providing high current output capability and stable output
voltage open manifold applications in the hazardous, flammable, explosive
environment.
The main advantages are:
transfer of measurement data from explosive areas (Ex-zones) to
safe areas without galvanic connections
protection class IP68 for outdoor applications
no wiring, no ground loops

SECU-DATA xxxM and also SECU-DATA xxxC have internal block terminals (type: WAGO series 256, ATEX certified) for connection of the corresponding external wires.
Important:
Only qualified personnel with appropriate training and authorisation by the
installation manager is entitled to connect SECU-DATA xxxx to an existing
installation. Adhere to all applicable, local safety regulations.
Important:
Check carefully if either the SECU-DATA xxxM on the measurement site or
the SECU-DATA xxxC on the controller location are operated in Ex-zone 1.
If so, then an additional barrier SECU-BAR 125 has to be installed outside
of the Ex-zone 1 between the not intrinsically safe power supply and the
SECU-DATA xxxx to achieve the required level of ignition prevention.
Hint: For SECU-DATA systems using the SECU-DATA 500C as a receiver
the function of the relay contacts can be reconfigured from make contacts
to break contacts, see section Settings-SECU-DATA 500C relay configu-ration on page 30.
Attention: In case of connection problems SECU-DATA maintains the
last valid information on the receiver output. This is valid for the current output of SECU-DATA 42X/142X and also for the relay outputs of
SECU-DATA 500C/1500C. For overfill prevention applications with
SECU-DATA 600M/710M it is important to ensure the turn-off of pumps
in case of radio failures. This can be achieved by connection the make
contact of Re1 of the SECU-DATA 500C/1500C in series to the “RFstatus” relay contact.

Functionality:
The status of the relay contacts Re1 and Re2 connected to the inputs of the
SECU-DATA 500M, is detected and sent per RF-connection to the receiver
module SECU-DATA 500C / 1500C.
Note: There is a current limited voltage present on the inputs for testing the
relay contact status. Therefore the contacts have to be potential free and
insulated, terminals 4 and 6 are internally connected within the SECUDATA 500M. The contact status (“open“ or “closed“) is reproduced on the
relay outputs Re1 and Re2 on the SECU-DATA 500C / 1500C. The contact
function, make or break, can be configured. The rated switching capacity is
30 V / 500 mA.
Important application note: SECU-DATA maintains the last valid value on
the receiver outputs in case of connection problems. To ensure that the
connected controlled device is turned off (very important for overfill prevention systems!) the make contact of relay Re1 has to be connected in series
to the „RF-status“ contact (blue line in the connection diagram).

SECU-DATA 500C / 1550C is used as the receiver, for the terminal connections see section SECU-DATA Relay on page 18 in this chapter.
Functionality:
The connected probe is tested for basic functionality: If the probe current is
below 0.4 mA or higher than 6 mA, relay Re2 of the receiver SECU-DATA
500C is activated per RF-connection, the contact is closed. This can be
used to issue an alarm message. The contact is connected to terminals 5, 6
of the SECU-DATA 500C / 1500C.
During the filling process the contact of relay Re1 SECU-DATA 500C /

the power supply terminals of a SECU-DATA xxxx device.
Security & Electronic Technologies GmbHPage 23
Remarks for mounting the SECU-BAR 125
SECU-BAR 125 uses an insulated housing for DIN-rail mounting. The insulation provides utmost safety during the installation – short circuits via the
housing, indirect touching of live conductors is impossible.
Please, adhere to all local safety regulations and standards (like DIN VDE
0100, VBG4, etc.) and follow the instructions of the manufacturer and of the
plant manager.
The wiring of the connection terminals is done with the provided selfclearing spring-clips and plus-minus screws.
First of all install the wiring to the SECU-DATA xxxx, and afterwards the
connections to the not intrinsically safe power supply. Snap the SECUDATA 125 simply on to the DIN-rail.
Wiring of the SECU-DATA xxxx:
1. For the wiring use round wires of type: 0,08 – 2.5 mm2 cross section, AWG 28 – 12, flame propagation characteristics as per IEC
60332-1-2, within a round cable to ensure the water protection
2. Strip the wires off app. 5-6 mm
3. Depress each of the levers of the terminal block (Type WAGO series 256, ATEX certified for EEx-i applications) with a small screw
driver
4. Put the stripped wire end into the terminal and release the lever
again
5. Close the SECU-DATA xxxx housing again and mount it to the final
location with the supplied screws in the provided holes of the housing. Take care for correct positioning of the sealing elements. For
metal base planes ensure that there is some space between the
RF-antenna and the metal material to maintain the best effective
range of the RF connection.
Remark: After delivery one cable gland is sealed waterproof with a cap.
This is useful if only one cable gland shall be used.
Page 24Security & Electronic Technologies GmbH
Putting into service a SECU-DATA 42xx
1. Connect the probes and the evaluation equipment to the SECUDATA 42xx units
2. Turn on the DC power supply in the range of +11 V … +40 V
3. Match one pair of instruments together:
Set the same channel block number on both instruments – factory
default is block #6 – details se chapter Settings-Selection of the RF-channelblock
Match the instruments together – detail see chapter Settings-
Matching two SECU-DATA xxxx
4. Both SECU-DATA 42xx modules will establish an RF-interconnection immediately, the green RF-indicators are blinking. After
some seconds they are continuously on – the connection is active.
5. The current on the input of the SECU-DATA 42xM is reproduced
precisely on the output of the SECU-DATA 42xC / 142xC for evaluation with the controller equipment.
6. Check the current values on the evaluation instrument for
plausibility.
The commissioning is completed now successfully.
Security & Electronic Technologies GmbHPage 25
Training
The operation of the SECU-DATA xxxx instruments is intentionally very
easy, thus a training as per EC Directive 94/9/EC is not required.
Dismantling
Important:
If you detect any damage of the housing, controls, connection wires or other
connected devices, immediately disconnect the unit from the power supply.
If you cannot ensure the safe operation of the device, immediately shut
down the unit and the respective accessories, secure them against inadvertent switching on, mark them clearly as “defective, out of order” and
send them in to an authorized service facility.

organized in 8 blocks with 8 channels each. The default setting is block #6.
Two SECU-DATA xxxx instruments are able to communicate only if the
same block for RF-channels is set on both instruments.
Procedure for both units:
1. Open the housing of the SECU-DATA xxxx. Avoid the intrusion of
moisture and pollution while the instrument is open to maintain the
reliability
2. Turn on the power supply of the SECU-DATA xxxx
3. Press the B-button two times shortly
4. The green “RF“-LED will blink several times, the number of light
pulses gives the actual number of the channel block (1 to 8).
5. The light pulses are repeated after a 1 s pause. Each press on button A increments the block number by 1. On the end of the range
the block number falls back from 8 to 1 automatically.
6. An interruption of the power supply aborts the procedure, the original block number remains in memory; the actual one is not stored.
7. The procedure can be finished by pressing the B-button; the actual
block number is stored permanently.
8. Repeat this procedure for the second SECU-DATA xxxx to set the
same block number
If required you may check the block number using steps 1 to 4 as described
above.

Matching two SECU-DATA xxxx
After the delivery SECU-DATA xxxx instruments are not matched together.
This has to be done during setup. Also after replacement of a unit, after
service and repair it might be necessary to repeat the tuning procedure.
Procedure for both units:
1. Open the housing of the SECU-DATA xxxx. Avoid the intrusion of
moisture and pollution while the instrument is open to maintain the
long-term reliability
2. Turn on the power supply of the SECU-DATA xxxx
3. Press shortly on both instruments the A-button
4. The green “RF”-LED and the yellow “Power“-LED on the SECUDATA xxxx start blinking alternately – the instruments are in the
matching mode now
5. After completion both instruments perform automatically a RESET
– the red LED flashes shortly. If the tuning process is not successful you can abort it by pressing shortly the button A – the original
settings remain in memory
6. Now the green “RF”-LED and the yellow “Power”-LED on both instruments are continuously on – the matching procedure is finished
successfully and the RF-connection is established.
Page 28Security & Electronic Technologies GmbH
Contact 6-7 is closed
as long as the RFconnection is established.
This circuitry provides
best reliability: if the
RF-connection is lost
or a power failure of
the SECU-DATA xxxx
occurred, the contact
opens and the alarm
lamp will be turned on
immediately.
Inverter relays can be
used also. Additionally the contact function
can be configured.

Monitoring the RF-status, alarm generation
Depending on the application it might be important to monitor the status of
the RF-connection and to generate an alarm indication in case of interruptions.
Important: During interruptions of the RF-connection SECU-DATA xxxC
instruments freeze the latest transmitted value and keep them on the output.
The status of the RF-connection can be tested via relay contacts.
SECU-DATA xxxx incorporate a relay contact, a make contact, which is
closed as long as the connection is active. The rated switching capacity of
the contact is 30 V / 500 mA.
Hint
Also the instruments SECU-DATA xxxM located on the measurement side
are equipped with such a relay contact with the same functionality. Thus an
alarm indication can be realised on the measurement site too.
If you want to realise an alarm signal (e.g. by a lamp) on the controller site
make use of this contact (principle diagram):
SECU-DATA 42xM, 42xC, 142xC, 600M
Security & Electronic Technologies GmbHPage 29
Contact 7-8 is closed as
long as the RFconnection is established. During RFinterruptions it is open
and the lamp goes on to
indicate an alarm condition.
The rated switching capacity of the contact is
30 V / 500 mA.

SECU-DATA 500C relay configuration
After delivery the relay contacts are configured as make contacts, which
can be changed to break contacts if required.
Procedure:
1. Turn on the power supply of the SECU-DATA 500C / 1500C
2. Press and keep depressed the button A and press two times the
button B. The green “RF“-LED starts blinking, the number of pulses
indicates the relay mode:
make… contact closes if the relay is activated.
break… contact opens if the relay is activated.
3. Pressing of button B saves the settings
Hint: On all the other SECU-DATA xxxx instruments this configuration
is also provided but for the RF-relay function only, thus mode 1 and 2
are available only.

Maintenance
Instruments of the SECU-DATA xxxx product range do not need any
maintenance, no user serviceable components are inside of the housing.
Important:
Repair and service tasks can be done by qualified service personnel only.
This is the only way to maintain the required level of ignition prevention.
The service activities carried out are documented and these files are kept in
archives for at least 10 years.
Warranty
For the actual services and conditions see the internet home page
www.secu-tech.at, see the GTCS – General Terms and Conditions of Sale.
Disposal
SECU-DATA instruments must not be disposed of via the municipal waste
collection system.
Security & Electronic Technologies GmbH. takes back used SECU-DATA
instruments for appropriate disposal for a small charge.
The symbol for disposal via qualified recyclers is attached visibly and permanently on the instrument.

Troubleshooting
Problem: The RF-connection cannot be established
Solution 1:
Check:
Is the supplied antenna mounted correctly?
Are there obstacles which block the propagation of the RF waves?
Is the distance between transmitter and receiver less than 1 km?
Select an optimal position for the antenna, antenna extension cables are
available as an option.
Solution 2:
Interrupt shortly the power supply of both SECU-DATA xxxx units and turn
them on again. The modules will establish a new connection and they will
search for free undistorted RF-channels automatically.
Solution 3:
If this does not solve the problem match together the two instruments again.
For the procedure see chapter “Settings - Matching two SECU-DATA
xxxx “
Solution 4:
If the tuning cannot be carried out successfully check the number of the RFchannel block. Both instruments have to operate within the same block of 8
RF-channels.
For the procedure of verification and re-definition of the RF-channel block
see chapter “Settings - Selection of the RF-channel block”
If all measures described in this chapter do not solve your problem then
send in the modules with a short description of the problem and with a copy
of the delivery note (in case of warranty claims) to the manufacturer or to an
authorised service facility.

Technical specification
Power supply concept
According to ignition protection requirements the following power supply
systems are available:
For standard applications outside Ex-zones SECU-DATA xxxx is supplied
from a standard DC supply in the range of +11 V … +40 V. If the transmitter
and/or the receiver are installed in Ex-zone 1 a SECU-BAR 125 barrier has
to be inserted in between to achieve intrinsic safety as per EN 60079-11.
Radio frequency data transfer
Transmitting and receiving frequency in the 433 MHz band, very narrow
bandwidth, 64 channels in 8 frequency blocks (selectable on the instrument), 25 kHz channel separation, effective range up to 1 km or even more
in open areas, best temperature stability, insensitive to distortions, automatic selection of an undistorted channel, RF data transmission rate: 4.800
Baud (data bits/s, the effective data rate is 2.400 Baud). Data loss is prevented by using a CRC16 error correction.
A potential-free relay contact is used to monitor the status of the RF connection, e.g. to issue an alert in case of an RF interruption
