Page 5: Introduction
1.1. Purpose of the document The subject of manual are the installation and exploitation data of the APT-2000ALW MID smart temperature transmitters with direct resistive sensor Pt100, designed to work in user’s thermowell. Transmitters APT-2000ALW MID meet the requirements of the EN12405-1:2018 Standard, harmonized to Directive 2014/32/EU (MID) and are used for type 2 of gas conversion device. -
Page 6: Transmitter Set Range
EN.IO.APT.ALW.MID 1.4. Transmitter set range The figure below shows the transmitter set range and limits related to allowable set range, digital processing range and saturation limits of A/D transducer of temperature measurement. As standard, values of 4 mA/20 mA currents are assigned to LRV/URV points. In order to obtain reverse characteristics, it is possible to reverse the assignment so that the LRV/URV points are assigned to 20 mA/4 mA currents. -

GUARANTEE General terms and conditions of guarantee are available on the manufacturer's website: www.aplisens.com/ogolne_warunki_gwarancji. The guarantee shall be repealed if the device is used against its intended use, or failure to comply with user’s manual or interference with the structure of the device. -
Page 8: Identification
6.1. General recommendations Temperature transmitter APT-2000ALW can be mounted in any position but always in thermowell. The housing of the transmitter should be protected against hot air streams by appropriate location of the transmitter or by installing thermal screens so that the transmitter does not heat up to a temperature higher than the permissible one. -
Page 9: Electrical Connection
EN.IO.APT.ALW.MID ELECTRICAL CONNECTION 7.1. Cable connection to transmitter terminals All connection and installation operations shall be performed with disconnected supply voltage and other external voltages, if used. Failure to provide proper connection of the transmitter may result in danger. Risk of electric shock and/or ignition in potentially explosive atmospheres. 7.1.1. - Page 10 EN.IO.APT.ALW.MID In order to establish the local communication, it is necessary to: − remove HART communication jumper (item 2); − connect the communicator or modem to electrical terminals (item 5). Opening of the HART jumper results in applying resistance of 240 Ω in series in line 4...20 mA.

Page 12: Resistance Load In Power Supply Line
EN.IO.APT.ALW.MID 7.2.5. Resistance load in power supply line The power line resistance, power source resistance and other additional serial resistances increase the voltage drops between the power source and the transmitter terminals. The maximum current of Exd or Exi transmitters under normal operation conditions is defined as I_max = 20,500 mA, in the high alarm state, the I_max current rises to at least 21,5 mA. -
Page 13: Operation
EN.IO.APT.ALW.MID OPERATION The IP 66 degree of the transmitter housing protection for applications with gaseous fuels from 1 and 2 families in accordance with EN 437 Standard is ensured by the housing design as well as cable entries and plugs with HNBR or NBR seals. When you intend to use own cable inlets and plugs, you should use components dedicated to Ex zones, guaranteeing compliance with the requirements regarding: ambient temperatures, resistance to gaseous fuels, families 1 and 2 and IP degree. -
