OPTIMASS 7400C (OPTIMASS 7000 + MFC400 ); see PTB XX ATEX XXXX X
All OPTIMASS sensors (separate and compact) and converters are available with a painted fin-ish for aggressive environments. For these meters, the model name has the suffix -Painted
Example: OPTIMASS 1400C-Painted
The output configuration of the MFC400 is described by the CG33.XYZ number listed on thedata label. See section 4 for a detailed description.
All types are intended for use in Zone 1 Category 2.All types (except OPTIMASS3000/3000F/3400C) are also intended for Zone 0 Category 1 areas. Refer to the Ex markingstable for each meter. In addition, certain versions of MFC400 have intrinsically safe signal out-
puts suitable for use in Category 1 areas.
1.2 MFC 400F
The MFC 400F has intrinsically safe connections to the mass flow sensor with either increasedsafety or intrinsically safe signal outputs. The signal output connection compartment can beconfigured with protection type Ex d or Ex e. The marking is as follows:

2.1 General
Due to the influence of the media temperature, mass flow sensors and compact mass flowmeters are not allocated to any fixed temperature class. For allocation regarding thenon-insulated and heated/insulated versions, please refer to the tables below.
The temperature limits below apply under the following conditions:
The flowmeter is installed and operated in accordance with the installation directions givenin the Installation and Operating Instructions.
The flowmeter is not heated up by any additional heat radiation (direct solar radiation, heatfrom adjacent plant parts) so causing it to operate above the permissible ambient tempera-ture range.
Insulation is not hindering free ventilation of the mass flow converter housing.
2.2 MFC 400F
The MFC 400F mass flow converter is suitable for temperature classes T6.T1 with amaximum surface temperature T75 C. with the following restictions on ambient temperature:
1 Aluminium converter housing:
Tamb: - 40C...+65C
2 Stainless steel converter housing:
Tamb: - 40C...+60C

CONNECTION OF SEPARATED SYSTEMS OPTIMASS3
3.1 General
In the case of separate systems, the sensor and converter are connected using 5 pair lowcapacitance cable, with outer screen. Each cable pair carries an intrinsically safe circuit.
The cable MUST NOT exceed the capacitance and inductance limits specified in section 3.2below.
The requirements of IEC/EN 60079-14 should be adhered to when installing the flowmeter.
3.2 Cable Parameters
When selecting the connecting cable, note the following points:
The maximum permitted total capacitance and inductance for the connecting cable is:
CL = 90 nF
LL = 36 H
Cable supplied by Krohne meets the following specification:
CL < 78 pF/m
LL < 0.8 H/m
The cable must have a temperature rating equal to, or better than, the maximum range oftemperatures present in the installation. When calculating the temperature range, youMUST give consideration to the temperature gradients on the flow sensors (see the notes insection 2).
The cable must be capable of withstanding a test voltage of 1000V AC and have a minimuminsulation thickness of 0.2mm, as per IEC/EN60079-14 section 12.2.2.7
3.3 Equipotential bondingThe MFC 400F mass flow converter or OPTIMASS X400C mass flow meter must be included inthe equipotential bonding of the installation using the equipotential bonding terminal on themass flow converter housing wall bracket or mass flow meter housing mounting stem respec-tively.
In separated systems, a screened cable is used and is earthed at both the mass flow sensorand the mass flow converter ends. You MUST fit an equalisation cable with a minimum crosssection area of 4mm2, to the equipotential bonding terminals locted on the mass flow converterhousing bracket and the mass flow sensor electronics stem.

OPTIMASS4 ELECTRICAL CONNECTIONS
4.1 General The MFC 400F mass flow converter (or OPTIMASS X400C mass flow meter) must be includ-
ed in the equipotential bonding system of the installation. Do this by using the the equipo-tential bonding terminal on the mass flow converter housing wall bracket, or mass flowmeter electronics stem.
The covers of the housing electronics compartment and the housing itself, are providedwith a "flameproof" thread. The thread is a tight fit because of explosion proofrequirements. Screw the cover on or off with care and never use excessive force.
Keep the threads free of dirt and apply Teflon grease (eg. NONTRIBOS type Li EP2). Thegrease will help to prevent the threads from locking due to corrosion
To open the covers, remove the hexagonal "retention" lock using a 2.5mm hex head tool.After closing the covers, refit the "retention lock".
Electronics compartment:
Allow the electronics to de-energize before opening the electronics compartment. For T6class meters wait for a minimum of 35 minutes and for T5 class meters, wait for aminimum of 10 minutes.
Terminal compartment:
The terminal compartment can be opened in hazardous areas, for a short period of time(eg. to check wiring configuration) with the power supply connected, where:
a) the terminal compartment has an ignition protection type increased safety (standard) and
b) the I/O circuits have an ignition protection type intrinsic safety and
c) the cover for the power supply terminals (L,N) is closed (see illustration)
Work on I/O terminals A-D can be carried out with the power supply connected, provided thatthe regulations regarding intrisically safe circuits are followed
As soon as the work has been completed, the cover must be replaced and the retention lock re-fitted.

4.3 Ex i signal I/O connections
Following intrinsically safe signal I/Os are available:
The I/O circuits named Ex i I/O, Ex i Option are always in the Intrinsically safe (Ex ia) type ofprotection. The I/O circuits Fieldbus I/O Profibus PA and Fieldbus I/O Foundation Fieldbuscan be in the Intrinsically safety type of protection.
A maximum of 4 intrinsically safe (Ex ia) in/outputs are possible. All intrinsically safe cir-cuits are galvanically insulated with respect to earth and each other. To avoid summation ofvoltages and currents, the wiring of these Ex ia circuits must be sufficiently separated, e.g.in line with the requirements of standard IEC/EN 60079-14, clause 12.2.
The Ex ia signal in/outputs may only be connected to other Ex ia or ib certified device (e.g.intrinsically safe isolation amplifiers), even if such devices are installed in the non-haz-ardous area!
Connection to a non-Ex i apparatus cancels the Ex ia properties of the flowmeter.
Terminals L, N (or L+, L-) for mains connection are always non-intrinsically safe. To achievethe necessary spatial separation to IEC/EN 60079-11 between the non-Ex i and Ex i circuits,the mains terminals are provided with a semi-circular insulation cover with a "snap-in"lock. This cover MUST be closed before establishing the power supply to the converter.

OPTIMASS5 SERVICE AND MAINTENANCE
5.1 Maintenance
The OPTIMASS flowmeters are maintenance free with respect to the flowmetering properties.Within the scope of periodic inspections required for electrical equipment installed in haz-ardous areas it is recommended to check the flameproof converter housing and covers forsigns of damage or corrosion.
5.2 Replacement of mains fuseOpen the window cover. Press the two metal clips on each side of the display and pull the dis-play unit forward. Move the display-unit sideward, out of the way. Loosen the two crossheadscrews holding the electronic unit is place. Slide the electronic unit forward, with care. Whenthe unit is almost completely removed from the housing, disconnect the long rectangular (10-pole) blue connector at the back-end of the unit. This connector is for the flow sensor circuits.Remove the unit from the housing.
The mains fuse is situated in a fuse holder at the back-end of the electronic unit. The specifica-tion must be as follows:
