If Uo > U2Q, UQ, I0, P0 have the following relations: Po = UQ 4 Io If Uo 1/2UQ , UQ, I0, P0 have the following relations: Po = Uo(UQ-Uo) Rw Resistance Rw: Rw = UQ Io 11.3. Orthogonal power supply example Uo = 24 V Io = 25 mA Po = 0.6 W Uo = 24 V Io = 50 mA Po = 1.2 W Orthogonal power supply means that the voltage of an intrinsically safe power adapter does not change until the current limiter is activated. The level of protection of orthogonal power supply adapters is usually "ib". A transmitter supplied from such power adapter is usually an "ib" intrinsically safe device. An example of power supply in practice:A stabilized power adapter with Uo = 24 V, "ib" protection level and current limited to Io = 25 mA. 12 Revision 01.A.008/2023.01 EN.IX.APC.APR.ALW 12. CONNECTING Exi TRANSMITTERS AND PROBES Transmitter and equipment in the transmitter measurement loop must be connected in compliance with intrinsic safety and explosion proofing standards and conditions for application in risk zones. If intrinsic safety rules are not followed, explosion can occur and people can be exposed to danger. Figure 5. Connecting Exi transmitters and probes The transmitter is equipped with an additional communication resistor RD=240. <SIGNAL -> and <TEST -> terminals are short-circuited in factory. RD resistor is used when the transmitter need to be communicated with locally (from its terminals) and a Ro < 240 . <SIGNAL -> and <TEST -> terminals must be open-circuited then. If the medium temperature can exceed Ta=80°C, separating elements, such as diaphragm separators, siphon tubes, etc., should be used. The transmitter operating temperature Tp must meet the TpTa condition. The electrical system for connecting transmitters should meet installation requirements of applicable standards. For APC-2000ALW / L, APR-2000ALW / L and APR-2200ALW / L transmitters, equalization of the electric potential between the transmitter housing and the measuring head remote from the transmitter should be ensured. No repairs or alterations to the transmitter electrical system are permitted. Only the manufacturer or a facility authorized by the manufacturer may assess damages and repair the device (if possible). "Version SA" transmitters should be supplied from devices equipped with galvanically isolated power supply. If galvanically isolated power supply is not possible, the transmitter or metal parts connected to it should be properly grounded, for instance Revision 01.A.008/2023.01 13 EN.IX.APC.APR.ALW with an equipotential wiring or an equipotential bonding between the transmitter and the negative pole of power supply barrier. A transmitter enclosure has two holes for installing a cable entry and blinding plug with M20x1.5 or 1/2 NPT thread. Transmitters with common Exi and Exd designation, as presented in Figure 1, become intrinsically safe transmitters when Exi field is permanently marked. If such transmitter is delivered without a cable gland, the customer is obliged to install a cable gland with at least IP66 protection and operation temperature range suitable for the installation site. In transmitters used in dust explosion zones, the cable glands installed by the customer should be certified and have a designation proper to dust zones where the transmitters are used. 13.

The transmitter operating temperature Tp must meet the TpTamax condition. Revision 01.A.008/2023.01 15 EN.IX.APC.APR.ALW 14.2. Power supply, connection and operation of Exd transmitters Connect the transmitter according to the wiring diagram (Figure 6). The transmitter electrical connections in potentially explosive zones should be made by personnel having necessary knowledge and experience in this respect. The transmitters should be properly grounded by means of a grounding terminal. If the transmitter has metal contact with grounding structural elements or piping, separate transmitter grounding is not necessary. Transmitter and equipment in the transmitter measurement loop must be connected in compliance with explosion proofing standards and conditions for application in explosion risk zones. If these rules are not followed, explosion can occur and people can be exposed to danger. Figure 6. Connecting Exd transmitters and probes The transmitters should be supplied with maximum voltage specified in the table below (24 VDC rating) from transformer power supplies or other devices providing at least enhanced isolation between primary and secondary winding in which voltages not larger than 250 VAC occur. It is responsibility of the user to provide power supply compliant with the requirements above. Table 5.

In order to secure the side covers against loosening, unscrew the hex socket screws pressing the screw heads against the edges of the covers. The method of locking the covers against unscrewing and the possible method of sealing the transmitter are presented in the PL.IO.APC.APR.ALW.SFT user manual. No repairs or alterations to the transmitter enclosure elements and electrical system are permitted. Repairs on flameproof joints are not permitted. Only the manufacturer or a facility authorized by the manufacturer may assess damages and repair the device (if possible). Due to the type of enclosure material (light alloy with high aluminum content), the user is obliged to ensure that in the transmitter installation site its enclosure cannot be hit and, consequently, damaged. In a transmitter enclosure there are two holes for installing, one for a cable entry and second for a blinding plug with M20x1.5 or 1/2 NPT thread. As standard, the transmitter is delivered to the customer without cable gland installed. After consultation with the manufacturer, the user can purchase a transmitter with a cable gland, or without a cable gland and the missing cable gland purchase separately. A transport plug is installed in the cable gland place. In such case, the transport plug should be removed and appropriate cable gland installed ( Figure 7) before the transmitter is installed. It is responsibility of the user to install a certified cable gland compliant with the list of equivalent cable glands in "Table 6. List of equivalent cable entries". As a blinding plug, an Aplisens plug supplied with the transmitter or a certified blinding plug compliant with the list of equivalent blinding plugs in Table 7 can be used. It is allowed to install other types of certified cable entries and blinding plugs about marking Exd IIC Gb, Extb IIIC Db and Exd I Mb with at least IP66 protection and -40°C...75°C temperature range. Apply LOCTITE 577 or SWAK MS-PTS-50 on the 1/2 NPT thread of cable gland before installation. When connecting, make sure that the cable type and diameter is suitable for the cable gland used and temperature in the installation site. Figure 7.

If a cable of different design has to be used, it should be agreed on with the transmitter manufacturer in order to choose a suitable cable gland or individually purchase a cable gland suited to the cable used. The list of equivalent cable entries is given above (Table 6). The cables should be protected from damage by routing them in cable trays, jacket tubes, cable ladders, by using fixed mounts, etc. When periodic inspections are performed, the covers tightness, cable entry and cable fixing in the cable entry should be checked. Visually check the enclosure and cable for mechanical damage, and the nameplate for legibility. The sensor diaphragm should be also included to periodic inspections. There shouldn't be a signs of damage. During maintenance it is recommended to apply acid-free petroleum jelly on threads connection. 18 Revision 01.A.008/2023.01 EN.IX.APC.APR.ALW The diaphragm should not be exposed to damage during transmitter installation and operation. The transmitter diaphragm is made of stainless steel or Hastelloy and must not be exposed to contact with a medium that may damage it. The connecting and operating general rules for an Exd transmitters should be compliant with the rules and standards applicable to devices in a flameproof enclosure: EN 60079-14 Electrical devices in explosive atmospheres. Part 14: Electrical installations in risk areas (other than mines). EN 60079-17 Electrical devices in explosive atmospheres. Part 17: Electrical installations inspection and maintenance in risk areas (other than mines). Due to possible damage, the transmitter should be protected from heating above 80ºC also when explosion hazard does not occur. 15. ADDITIONAL INFORMATION 15.1.
