Functionality:

The status of the relay contacts Re1 and Re2 connected to the inputs of the
SECU-DATA 1500M, is detected and sent per RF-connection to the receiv­er module SECU-DATA 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 1500M.
The contact status (“open“ or “closed“) is reproduced on the relay outputs
Re1 and Re2 on the SECU-DATA 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 output in case of connection problems. To ensure that the con­nected controlled device is turned off (this is 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 1500C is used as the receiver, for the terminal connections
see section SECU-DATA 1500 on page 15 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
1500C 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 1500C.
During the filling process the contact of relay Re1 SECU-DATA 1500C is
also closed via RF-signals (probe current is more than 2 mA); if the tank is
full (filling is not permissible, probe current below 1 mA) Re1 opens.

Wiring of the SECU-DATA xxxx:

1. For the wiring use round wires of type: 0,08 – 2,5mm2 cross section,
AWG 28 – 12, flame propagation characteristics as per IEC 60332­1-2, 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) 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 20 Security & Electronic Technologies GmbH

Putting into service a SECU-DATA 142xx

1. Connect the probes and the evaluation equipment to the SECU­DATA 142xx 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-channel block
Match the instruments together – detail see chapter Settings-

Matching two SECU-DATA xxxx

4. Both SECU-DATA 142xx 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 142xM is reproduced
precisely on the output of the SECU-DATA 142xC for evaluation
with the controller equipment.

6. Check the current values on the evaluation instrument for
plausibility.

The commissioning is completed now successfully.

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.

Selection of the RF-channel block

SECU-DATA 1xxxx instruments use one RF-channel out of 64. These are
organized in 8 blocks with 8 channels each. The default setting is block #6.
Two SECU-DATA 1xxxx 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 1xxxx. 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 1xxxx

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 1xxxx 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 1xxxx

After the delivery SECU-DATA 1xxxx 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 1xxxx. 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 1xxxx

3. Press shortly on both instruments the A-button

4. The green “RF”-LED and the yellow “Power“-LED on the SECU­DATA 1xxxx 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.

Security & Electronic Technologies GmbH Page 23

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 1xxxC
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 1xxxx 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 1xxxM 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 142xM, 142xC, 1600M, 1700M

Contact 7-8 is closed as
long as the RF­connection is estab­lished. During RF­interruptions it is open
and the lamp goes on to

SECU-DATA 1500C 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 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 1xxxx 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 1xxxx 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 1xxxx 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

1xxxx “
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 an 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.
