Structure of the extended order code

• Basic specifications

The features that are absolutely essential for the device (mandatory features) are specified in the basic

specifications. The number of positions depends on the number of features available.

The selected option of a feature can consist of several positions.

• Optional specifications

The optional specifications describe additional features for the device (optional features). The number of

positions depends on the number of features available.

The features have a 2-digit structure to aid identification (e.g. JA). The first digit (ID) stands for the feature

group and consists of a number or a letter (e.g. J = test, certificate).

The second digit constitutes the value that stands for the feature within the group (e.g. A = 3.1 material

(wetted parts), inspection certificate).

Safety instructions:

General

• Staff must meet the following conditions for mounting, electrical installation, commissioning and

maintenance of the device:

- Be suitably qualified for their role and the tasks they perform

- Be trained in explosion protection

- Be familiar with national regulations

• For installation, use and maintenance of the device, users must also observe the requirements stated in the

Operating Instructions and the standards:

- GB50257-1996: "Code for construction and acceptance of electric device for explosion atmospheres and

fire hazard electrical equipment installation engineering".

- GB3836.13-1997: "Electrical apparatus for explosive gas atmospheres, Part 13: Repair and overhaul for

apparatus used in explosive gas atmospheres".

- GB3836.15-2000: "Electrical apparatus for explosive gas atmospheres, Part 15: Electrical installations in

hazardous area (other than mines)".

- GB3836.16-2006: "Electrical apparatus for explosive gas atmospheres, Part 16: Inspection and

maintenance of electrical installation (other than mines)".

- GB15577-2007: "Safety regulations for dust explosive prevention and protection".

- GB12476.2-2006: "Electrical apparatus for use in the presence of combustible dust,

Part 1-2: Electrical apparatus protected by enclosures and surface temperature limitation -

Selection, installation and maintenance".

• Install the device according to the manufacturer's instructions and national regulations.

• Do not operate the device outside the specified electrical, thermal and mechanical parameters.

• Only use the device in media to which the wetted materials have sufficient durability.

• Refer to the temperature tables for the relationship between the permitted ambient temperature for the

sensor and/or transmitter, depending on the range of application, and the temperature class.

• Modifications to the device can affect the explosion protection and must be carried out by staff authorized

to perform such work by Endress+Hauser.

• When replacing the probe electronics or opening the connection between the remote cable and the probe,

a jumper plug must be used or a short-circuit must be established between the probe contact and the

potential equalization conductor to avoid electrostatically charging the probe.

• After mounting and connecting the probe, ingress protection of the housing must be at least IP66.

Perform the following to achieve the degree of protection:

- Screw the cover tight.

- Mount the cable entry correctly.

• When using in hybrid mixtures (gas and dust occurring simultaneously), observe additional measures for

explosion protection.

Safety instructions:

Special conditions

Permitted ambient temperature range at the electronics housing: –40 °C ≤Ta≤+80 °C.

Observe the information in the temperature tables.

Device type FMP52, FMP55

• A probe coated with non-conductive material can be used if avoiding electrostatic charging of the probe

(e.g. through friction, cleaning, maintenance, strong medium flow).

• In the case of process connections made of polymeric material or with polymeric coatings, avoid electrostatic

charging of the plastic surfaces.

• After aligning (rotating) the housing, retighten the fixing screw (see Operating Instructions).

• When mounting the device:

- Exclude any mechanical damage or friction during the application.

- Pay particular attention to flow conditions and tank fittings.

• Continuous service temperature of the connecting cable: –40 to ≥+85 °C; in accordance with the range of

service temperature taking into account additional influences of the process conditions

(Ta,min and Ta,max +20 K).

• In the event of additional or alternative special varnishing on the housing or other metal parts:

- Observe the danger of electrostatic charging and discharge.

- Do not rub surfaces with a dry cloth.

• Only use certified cable entries or sealing plugs.

The metal sealing plugs supplied meet this requirement.

• Before operation:

- Screw in the cover all the way.

- Tighten the securing clamp on the cover.

Intrinsic safety

• The device is only suitable for connection to certified, intrinsically safe equipment with explosion protection

Ex ia / Ex ib.

• The intrinsically safe input power circuit of the device is isolated from ground. If the device is only equipped

with one input, the dielectric strength of the input is at least 500 Vrms. If the device is equipped with more

than one input, the dielectric strength of each individual input to ground is at least 500 Vrms, and the

dielectric strength of the inputs vis-à-vis one another is also at least 500 Vrms.

• Observe the pertinent guidelines when interconnecting intrinsically safe circuits (GB3836.13, GB3836.15,

GB3836.16).

• The device can be connected to the Endress+Hauser FXA291 service tool: refer to the Operating

Instructions.

• When the intrinsically safe Ex ia circuits of the device are connected to certified intrinsically safe circuits of

Category Ex ib for Equipment Groups IIC or IIB, the type of protection changes to Ex ib[ia] IIC or Ex ib[ia] IIB.

Regardless of the power supply, all the internal circuits correspond to Ex ia IIC type of protection (e.g. service

interface, external display, sensor).

Overvoltage protection

• For installations which require overvoltage protection to comply with national regulations or standards

(GB3836.13, GB3836.15, GB3836.16), install the device using overvoltage protection (e.g. HAW56x from

Endress+Hauser).

• Observe the safety instructions of the overvoltage protection.

Safety instructions:

Zone 0

• In the event of potentially explosive vapor/air mixtures, only operate the device under atmospheric

conditions.

- Temperature: –20 to +60 °C

- Pressure: 80 to 110 kPA (0.8 to 1.1 bar)

- Air with normal oxygen content, usually 21 % (V/V)

• Associated devices with galvanic isolation between the intrinsically safe and non-intrinsically safe circuits are

preferred.

• If there is a risk of dangerous potential differences within Zone 0 (e.g. through the occurrence of atmospheric

electricity), implement suitable measures for intrinsically safe circuits in Zone 0 (e.g. in accordance with the

requirements of GB3836.13, GB3836.15, GB3836.16).
