Supply power to transmitters from supply and measurement devices with applicable intrinsic safety certificates whose parameters of outputs to a hazard zone should not exceed the permissible transmitter power supply parameters specified above.

Linear power supply example
For example, linear power supply is provided by a typical barrier with the following parameters
Uo = 28V; Io = 0.1A; Po = 0.7W; Rw = 280.

Figure 3. Principle of power supply from a linear source.

Trapezoidal power supply example
Uo = 24V; Io = 50mA; Po = 0.7W
An example of trapezoidal power supply is shown in Figure 4

Figure 4. Principle of power supply from a trapezoidal source.

If Uo > UQ 2 UQ, I0, P0 have the following relations: Po =UQ ∗ Io4
If Uo ≤ 1/2UQ , UQ, I0, P0 have the following relations: Po =Uo(UQ−Uo)Rw
Resistance Rw: Rw =UQIo

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.

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

Milliammeter connection to TEST+ and TEXT- terminals enables to measure transmitter current without breaking the measuring circuit.

In explosion risk zones, control terminals can only be connected using instruments allowed for use in these zones.

The communicator must be permitted for use in the explosion risk zone, e.g. Aplisens KAP-03Ex. If no such permission is available, the transmitter should be configured and calibrated in the safe zone and the communicator must not be connected to a line coming into a explosion risk zone.

The transmitter is equipped with an additional communication resistor RD=240Ω. and 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 Ω. and 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 Tp≤Ta 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 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.

-40ºC ≤ Ta ≤ 40ºC| -40ºC ÷ 40ºC| T6/T105ºC
-40ºC ≤ Ta ≤ 75ºC| 40ºC ÷ 75ºC| T5/T105ºC

If the medium temperature can exceed Tamax, separating elements, such as diaphragm separators, siphon tubes, etc., should be used. The transmitter operating temperature Tp must meet the Tp≤Tamax condition.

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.

In an explosion risk zone, do not remove the cover of supplied transmitter and do not connect to the terminals, and do not change the position of local indicator (display).

For transmitter calibration or check outside a risk zone, a communicating device can be connected to and terminals. The transmitter is equipped with a communication resistor RD = 240 Ω, which is short-circuited at and terminals in factory. RD resistor is used when the transmitter need to be communicated with locally (from its terminals) and a Ro < 240 Ω. and terminals must be open-circuited then.

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 an 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.

Use a shielded or unshielded, non-reinforced cable with compact structure and circular cross-section in an non-hygroscopic sheath made of an elastomer, e.g. YKSLY 21, YnTKSYekw 121, LIYCY 21.
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 o damage. During maintenance it is recommended to apply acid-free petroleum jelly on threads connection.

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).
