USER MANUAL SF211A IFM

• Prozessanschlüsse SF11*A = M12 SF21*A = G¼ SF31*A = G½

• Use in hazardous areas according to the classification II 1/2G (group II, category 1/2 G, apparatus for gas atmosphere).

• The flow sensors are suitable for installation in the partition 1/2G.

• Marking II 1/2G Ex ia IIC T4 Ga/Gb Ta = -20 ... +60°C Installation / Set-up The units must only be installed, connected and set up by qualified staff. The qualified staff must have knowledge of protection classes, regulations and provisions for apparatus in hazardous areas. Check whether the classification (see "Marking" above and marking on the unit) is suitable for the application. The flow sensors are only allowed to be connected to the specified control monitors type VS2000 Exi type of protection intrinsic safety II (1) G [Ex ia] IIC with the EC type test certificate PTB 01 ATEX 2075. Take the connection values into account. Connection to the following control monitors is allowed: SN2301, SN2302, SN2303, SN2304, SR2301

• Process connections SF11*A = M12 SF21*A = G¼ SF31*A = G½

• Permissible operating temperature range at the mounting location and maximum temperature range of the medium: -20 ... +60 °C

• In principle, the type test according to 94/9/EC only takes atmospheric conditions (0.8...1.1bar and mixture temperatures of -20...+60°C) into account. For pressures outside these ranges use must be assessed and approved by the user.

• Maximum effective internal inductance (Li) and capacitance (Ci) of the flow sensors (the values apply to potted cables): Article no. Cable length Internal inductance (total) in μH Internal capacitance (total) in nF SF311A 6 m 6 1.2 SF211A 6 m 6 1.2 SF111A 6 m 6 1.2 SF*1*A xx m 1*) 2*) Articles with cable/variants of cable units SF*1*A: For variants of cable units with potted cables of a different length the values of the cable must be taken into account.

0.68 μH (Li) / 95 pF (Ci) per metre of potted cable.

*1) Thus the maximum effective internal inductance of the unit results in: Li = 6 μH + cable length in (m) x 0.68 μH *2) Thus the maximum effective internal capacitance of the unit results in: Ci = 1.2 nF + cable length in (m) x 0.095 nF. Installation remarks / Installation

• Adhere to the relevant national regulations and provisions.

• The relevant installation regulations (e.g. EN 60079-14) must be adhered to.

• Avoid electrostatic charging on plastic parts and cables.

• Protect the units efficiently against damage.

• The cable must be firmly laid and protected efficiently against damage.

• Steps must be taken to ensure the equalisation of potential of metal parts (housing and fixing material).

• The unit is suitable for installation in the partition 1/2 G. Please take the special conditions for safe operation into account.4 Special conditions for safe operation The unit is suited for installation in the partition (category 1/2G); e.g. tank, pipes. Sealing at the transition (category 1/2G) must be rated according to the conditions of the corresponding application. The part of the sensor housing of corrosion-resistant steel (316S12) which reaches into the category 1G (zone 0) has a wall thickness of minimum 0.6 mm due to function. In the application the user must ensure that in this area risks, e.g. due to aggressive media or mechanical hazards, are excluded. Mounting in pipes or tanks: VS2000 Exi Category 1G (zone 0)

• The flow sensor has to be included in the recurrent pressure test of the tank or pipe.

• The unit must not be modified nor can it be repaired. In case of a fault please contact the manufacturer.
