FEATURES 
Temperature Transmitter with Universal input DAT1015 with PC programmability.
GENERAL DESCRIPTION
The temperature Transmitter DAT1015 is a hockey puck (Head mount) temperature Transmitter with PC programmability. The input can be thermocouples, Pt100, Pt1000, Ni100, Ni1000 or mV and potentiometer. The DAT1015 will linearize the temperature input and provide a 4-20mA output signal.
The DAT1015 is accurate to 0.1% full scale and has less than 0.01%/'f thermal drift.
The DAT1015 is programmable by PC based software which has been developed by DATEXEL to be user friendly.
For resistance and RTD's sensors it is possible to program the cable compensation for 3 or 4 wires.
It is possible to set the minimum and maximum values of the input and output ranges in any point of the scale, keeping the minimum span shown in the table below. Also high burn out alarm or low burn out alarm is selectable.
The DAT1015 is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
The DAT1015 is housed in a self-extinguish plastic enclosure suitable for DIN B in-head mounting.
There is a mounting kit available to mount the DAT1015 on DIN rail.
The DAT1015 is able to measure and linearize the standard thermocouples with internal cold junction compensation.
USER INSTRUCTIONS
The transmitter DAT1015 must be powered by a direct voltage between 10 to 32 V and applied to the terminals +V and -V.
The 4÷20 mA output signal is measurable in the power loop as shown in the section “Output/Power supply connections”; Rload is the input impedance of instruments on the current loop; to obtain a correct measure, the value of Rload will be calculated as function of the power supply value ( see section “Technical specification – Load characteristic”).
The input connections must be made as shown in the section "Input connections".
To configure, calibrate and install the transmitter refer to sections " DAT1015: configuration and calibration" and “Installation Instructions”.

INSTALLATION INSTRUCTIONS
The device DAT1015 is suitable for direct DIN B in-head mounting.
The transmitter must be fixed inside the probe by the proper kit.
By apposite stirrup, provided on request, it is possible to mount the device on DIN rail in compliance with EN-50022.
It is necessary to install the device in a place without vibrations; avoid to routing conductors near power signal cables .
CONFIGURATION AND CALIBRATION
Warning: during these operations the device must always be powered.
CONFIGURATION
1) Power-on the DAT1015 by a direct voltage between 10 ÷ 32 V or (only to configure) by a 9 V battery .
2) Remove the protection plastic cap on DAT 1015.
3) Connect the interface PRODAT to the Personal Computer and to device. (see section “ DAT1015: PROGRAMMING” ).
4) Run the software PROSOFT.
5) Set the parameters of configuration .
6) Program the device.
CALIBRATION CONTROL
With software PROSOFT running:
1) Connect on the input a calibrator setted with minimum and maximum values referred to the electric signal or to the temperature sensor to measure.
2) Set the calibrator at the minimum value.
3) Verify that the DAT1015 provides on output the minimum setted value.
4) Set the calibrator at the maximum value.
5) Verify that the DAT1015 provides on output the maximum setted value.
6) In case of regulation of value obtained in the step 3 and 5, use the ZERO and SPAN regulators of software PROSOFT. The variation introduced from these regulators must be calculated as percentage of the input range .
7) Program the device with the new parameters .
