4. INSTALLATION AND ELECTRIC CONNECTION
•Place of installation should be selected so that proper place should be available for handling.
•Housing of the units with flange or threaded connection can be rotated. After installing the unit housing can be turned to reach best position for reading display.
•Device should be fastened with two nuts of M4.

4.1 WIRING
•Transmitters are used in 2-wire systems with power supply of 10 … 36 V
DC. Resistance of the units in the loop depends on the voltage of the
power supply.
•For wiring shielded cable suggested in the Technical Data should be used.
•After removal of the housing cover and taking out the display module (if
any), the screw terminals can be accessed. Cover of the flame proof
housing can be removed after unhooking the clamp.
•The unit should be grounded by the inner or outer grounding screw.
•Loop should be connected to terminal 3 (+) and 4 (-). Other terminals are
for internal connection of the Pt sensor.
•The Pt100 sensor for types TW--should be wired as shown on
drawing at the right.
•Switch on the unit and make necessary programming.
•After wiring and programming ensure proper sealing and closing of the
cover (and fastening of the clamp with the flame proof models).

The unit may be damaged by electrostatic discharge (EDS) via its terminal, thus apply the precautions commonly used to avoid electrostatic
discharge e.g. by touching a properly grounded point before removing the cover of the enclosure.
4.2 SAFETY REGULATIONS FOR THE EX APPROVED UNITS
•Intrinsically safe units should be powered by duty certified intrinsically safe [EEx ia IIB] or [EEx ia IIC] device with features as per technical data above.
•Plastic coated probes may be charged electrostatically therefore such units should only be used for measurement of conductive medium and its specific
resistance must not exceed 104Ωm, even under the most unfavourable conditions and at the most unfavourable place.
•The Ex device should be grounded by its grounding screw.

5.1 PROGRAMMING
Adjustment of the unit to the conditions of the application will be carried out by programming parameters with the aid of the push buttons and following the procedure
on the display of the SAP-202 module. Manufacturer’s setting is as below:
DEFAULT
−Current output: 4 mA assigned to –50°C and 20 ma assigned to +200°C (+600°C),
−Noise suppression: 50 Hz
−Error indication: Iout = 3,8 mA
The THERMOCONT is fully operational without the SAP-202 display module (incorporated in types TB-, TL- , and TR-).
It is for programming and/or displaying measurement values.
The unit will measure during programming in accordance with the parameters set previously. The new, modified parameters will only be effective after
returning to the Measurement Mode
If the transmitter is left in Programming Mode by mistake, it will automatically return to Measurement Mode after 3 minutes and will operate with the parameters
entered during the last completed programming.

If after pressing
E
blinking does not spring over from the parameter address to the parameter value this means that
•the parameter is either a read-out type, or
•the secret code prevents the modification (see P19)
If the modification of the parameter value is not accepted i.e. the parameter value keeps blinking after pressing ENTER
E
,
•the modified value is either out of the range, or
•the code entered is not a valid one

5.1.3 Parameters – descriptions and programming
P0: - - - a Assignment of the (lowest) measured temperature to 4 mA
P1: - - - a Assignment of the (highest) measured temperature to 20 mA
The lowest and highest (limit) value of the temperature range is to be assigned to the 4 and 20 mA output current. This can be performed by two
methods
a: manually i.e. by entering the relevant values in P0 and P1 (Make sure that values to be programmed does not exceed the range of the unit in
question, the modification of the parameter value will not be accepted i.e. after pressing
E
the parameter value will remain blinking and refuse to
return to the address.)
The procedure to assign for instance +160°C to 4 mA in P0 is the following: press
E
+ to enter programming mode, go to P1 with
E
, enter 160
and press
E
to go back to the parameter address, finally press
E
+to exit programming/return to measurement mode).
b: automatically i.e. using the GET VALUE function at being in P0 and P1. For this method the probe should be in a medium with the required (zero
and high limit value) temperature. Successful setting will be indicated by the message SET displayed.
FACTORY DEFAULT: P0 -50°C
P1 +200°C or +600°C respectively
P7: - - - a Offset of characteristic
Displayed (and transmitted) temperature value can be diverted from that of measured by the sensor. This represents an offset of the characteristic so
that the displayed value will be throughout the whole range in line with a - for instance - control measurement, performed by a control thermometer.
Difference value should be entered here with its mathematical sign ( -) if it is minus.
FACTORY DEFAULT: 0
P9: - - - a Current generator test
In this parameter the actual current output (corresponding to the measured process value) will be displayed. Pressing
E
the blinking) current value
can be set for any value between 3,9 and 20.5 mA. The current output has to show the same value, which can be checked by an ampere meter.

P14: - - - - Software version
The software number of your transmitter can be viewed in this parameter.
P19: - - - - Secret code
Settings can be protected by a 4 digit number (secret code) other than 0 entered as value of this parameter. If the secret code is active the symbol
PROG is lighting and the value of the parameters can only be viewed. . If there is no secret code or it is not active the symbol PROG is blinking.
For opening secret code the old code should be entered. For modifying or deleting the secret code (modifying to 0000) the new code can only be
entered after opening old code. The procedure is as below: Go to P19 press
E
to select parameter address and go to parameter value, enter the old
code; press
E
to go to address and
E
again to return to value; enter new code or 0000.

5.3 HART COMMUNICATION
HART capable transmitters would communicate with the Nivelco made MULTICONT interface according to the HART standard. MULTICONT provides for the
powering and makes possible remote programming of the transmitters while (transmitter parameter values and) measurement data can be forwarded from the
MULTICONT on RS485 line.
6. MAINTENANCE AND REPAIR
The unit does not require regular maintenance. In case of need the diaphragm might be carefully cleaned. All repairs will be carried out in the premises of the
Manufacturer only.
7. STORAGE
Ambient temperature: -25 °C ...+60 °C
Relative humidity: max. 98 %
