Description 1.4 Principle of operation Fig. The device consists of an i/p converter module and a connected volume booster. The supplied direct current i flows through the plunger coil () located in the field of a permanent magnet (3). At the balance beam (1), the force of the plunger coil, which is proportional to the current, is balanced against the force of the dynamic back-pressure. The back-pressure is produced on the flapper (6) by the air jet leaving the nozzle (7). The supply air (SUPPLY 8) flows into the lower diaphragm chamber of the booster (8); a certain amount of this air determined by the diaphragm position flows past the sleeve (9) to the output (OUTPUT 36) of the converter. When the input current and thus the force at the plunger coil increases, the flapper plate (6) moves closer to the nozzle (7). This causes the back pressure and the cascade pressure p K forming upstream of the restrictor (8.) to increase. The cascade pressure increases until it is equal to the input current. When the cascade pressure increases, the diaphragm (10) and the sleeve (9) are pushed downwards causing the supply air to increase the output pressure p A until a new state of equilibrium is reached in the diaphragm chambers. When the cascade pressure drops, the diaphragm moves upwards and releases the sleeve. The output pressure p A can pass through the sleeve to be vented (EXHAUST port) until a new state of equilibrium is reached. Switch-off electronic function Converters with an input range of 4 to 0 ma are equipped with a slide switch which activates the switch-off electronic function. This function allows the input signal to be set to 0 ma if it falls below 4.08 ± tolerance. This causes the pneumatic output to be vented to approximately 100 mbar. This guarantees, for example, the tight shut-off function of a valve. If the characteristic line does not pass through zero like, for example, for an allocated output signal from 0.8 to.7 bar, then the pneumatic output is vented to a remaining pressure of approx. 0.3 bar when the switch-off electronic function is activated. 1.0 0.8 0.6 0.4 0. 5 4 3 1 bar bar 4 8 1 16 0 4 8 1 16 0 With an output of 0. to 1 bar Remaining pressure of approx. 0.1 bar ma With an output of 0.8 to.7 bar Remaining pressure of approx. 0.3 bar ma Fig. 3 Switch-off electronic function and remaining pressure EB 6116 EN 9
Installation Installation.1 Mounting position The converter is to be mounted horizontally with the pressure gauge (or stopper plug) facing upwards. If a different mounting position is used, the zero point must be readjusted as described in section 3.1. For devices with a degree of protection IP 54, it is essential to direct the EXHAUST port for venting downwards to face the floor.. Mounting The converter can be mounted to a wall, a pipe or directly to a control valve as illustrated in Fig. 4. The following accessories are required: Order no. 1400-616 for wall and pipe mounting Order no. 1400-617 for attachment to valve with cast yoke) Order no. 1400-618 for attachment to valve with rod-type yoke Wall and pipe mounting View onto the device Side view Valve with cast yoke/ rod-type yoke mounting View onto the device Plate 3 Rail 4 M6 x 16 screw 5 M6 x 5 screw 6 Lock washer B6 7 A6.4 washer 8 M8 nut 9 A8.4 washer 10 M8 x 5 screw 11 Clamp 1 Clamp 13 Wall or pipe bracket Mounting onto a valve with rod-type yoke Yoke bracket Fig. 4 Installation 10 EB 6116 EN
Installation.3 Electrical connection As far as the electrical installation of the device is concerned, the relevant national regulations governing the installation of electrical equipment and the national accident prevention regulations of the country of destination must be adhered to. In Germany, these are the VDE regulations and accident prevention regulations of the employer's liability insurance. For installation in hazardous areas, the following standards apply: EN 60079-14: 003 (VDE 0165 Part 1/8.98) "Electrical apparatus for explosive gas atmospheres" and EN 5081-1- (VDE 0165 Part /11.99) "Electrical apparatus for use in the presence of combustible dust". For the interconnection of intrinsically safe electrical equipment, the permissible maximum values specified in the EC type examination certificate apply (U i or U o ; I i or I o ; P i or P o ; C i or C o, and L i or L o ). Note! It is absolutely necessary to keep to the terminal plan specified in the certificate. Reversal of the electrical connections may cause the explosion protection to be ineffective! Screw off the cover of the housing and connect the wires for the input signal to the terminals 11 (+) and 1 ( ) using suitable cable glands or connectors. No additional voltage supply is required. Secure grounding conductor at the ground terminal located either inside or outside the housing. EEx d versions must be connected with an approved metal cable entry (certificate of conformity) or a seal box tube. Approved versions (certificate of conformity) are equipped with permanently sealed cable entries. green/yellow 4 to 0 ma input Fig. 5 Electrical connection EB 6116 EN 11
Operation.4 Pneumatic connection The connections for supply air (SUPPLY 8) and output air (OUTPUT 36) are designed as bore holes with either G ¼ or ¼-18 NPT threaded connections (see page 0). Customary screw glands for metal pipes or plastic hoses can be used. Supply air (see technical data on page 7) Min. + 0.4 bar above the upper signal pressure range value Max. 10 bar Max. 6 bar for Type 6116- (see page 6) Note! The supply air must be dry and free of oil and dust. The maintenance regulations for connected reducing stations must be observed. Blow out all air connections before attachment. Note! When extending the exhaust by connecting a pipe either to the exhaust angle piece or directly to the G or NPT connection, make sure that no water can enter at the end of the pipe. The pipe must have a sufficiently large cross-sectional area of at least 8 mm² = 6 mm inside diameter. 3 Operation 3.1 Checking zero point and span The device converts the input signal proportionally into the output signal. The signal ranges are specified on the nameplate. In case of a mounting position that is not horizontal or when the pressure gauge/ stopper plug does not face upwards, zero and span can be corrected by approx. 10 % using the electronics. To do this, proceed as follows: 1. Screw off the cover to access the ZERO and SPAN potentiometers on the circuit board.. Connect a pressure gauge (minimum accuracy class 1) to the converter output. 3. Set the supply air to 0.4 bar above the upper range value of the output signal and apply it to the device. 4. Deactivate the switch-off electronic function at the slide switch (5). Checking the zero point 5. Set the input signal to the lower range value with a suitable current source (e.g. for range 4 to 0 ma = 0. to 1 bar, set to 4 ma). The output signal of the pressure gauge should now indicate 0. bar. If this is not the case, readjust the zero point accordingly with the ZERO potentiometer. 1 EB 6116 EN
Operation Checking the span 6. Set the input signal to 0 ma (upper range value) using a suitable current source. The output signal at the pressure gauge should now indicate 1.0 bar. If this is not the case, readjust the span accordingly with the SPAN potentiometer. 7. Change the input signal abruptly from 0 to 0 ma (or tap gently the converter) and check whether the output signal assumes the upper range value of 1.0 bar. Note! As the adjustment of zero and span influence each other, recheck both values and correct them, if necessary. Electric terminal Zero point and span adjusters Switch for switch-off electronic function Fig. 6 Zero point and span correction Zero adjustment for special versions with an input signal of 0 to 0 ma. These versions do neither have potentiometers to adjust zero or span, nor the switch-off electronic function. The zero point can only be adjusted mechanically at the zero adjustment screw (1.1) of the i/p module. Caution! Never open devices with explosion-proof enclosures when the electrical power supply is connected; observe explosion protection regulations! Damage to the cover's thread and/or the connecting thread result in the immediate loss of EEx d protection. EB 6116 EN 13
Maintenance 4 Maintenance There are no specific maintenance measures to be carried out. To guarantee trouble-free operation of the converter, make sure that the supply air is always pure and clean. Air filters and separators of the connected pressure reducing station need to be checked at regular intervals. 4.1 Cleaning the throttle The throttle (see dimensional drawing on page ) is located inside the housing. It can be accessed from the back of the device. It can be taken out after the screw plug (Ø10) has been removed. When the output signal is too small or when there is no output signal at all, the throttle might be blocked. To remove all blockages, take the filter out of the throttle and clean or replace it. Filter Order no. 0550-0193 Throttle with filter Order no. 1390-0186 In addition, the pneumatic connections have filters with plastic rims (order no. 0550-013) which can be removed for cleaning. 5 Servicing explosion-protected devices If a part of the device on which the explosion protection is based needs to be serviced, the device must not be put back into operation until an expert has inspected it according to explosion protection requirements, has issued a certificate stating this or given the device a mark of conformity. Inspection by an expert is not required if the manufacturer performs a routine test on the device prior to putting it back into operation. The passing of the routine test must be documented by attaching a mark of conformity to the device. Explosion-protected components may only be replaced by original, checked components from the manufacturer. Devices that have already been used outside of hazardous areas and are intended for use in hazardous areas in future must comply with the safety demands placed on repaired devices. Prior to operation, they must be tested according to the specifications stipulated for "Repairing explosion-protected devices". 14 EB 6116 EN
Positioner attachment 6 Positioner attachment Analog positioners with Ex d explosion protection can be implemented by combining p/p positioner with a Type 6116- (Ex d) Converter. In the Type 6116 Converter designed for positioner attachment, the connection to the positioner is used in place of the booster. Another application involves upgrading p/p positioners to Electro pneumatic positioners (current signal input instead of the pneumatic signal). Type 6116-xx010111000xxxx with ½ NPT threaded connection and Type 6116-xx10101000xxxx with M0 x 1.5 threaded connection 6.1 Principle of operation The supplied direct current i flows through the plunger coil () located in the field of a permanent magnet (3). At the balance beam (1), the force of the plunger coil, which is proportional to the current, is balanced against the force of the dynamic back-pressure. The back-pressure is produced on the flapper (6) by the air jet leaving the nozzle (7). The supply air for the nozzle is taken from the pneumatic positioner (connection to the pneumatic input signal input signal 7). i/p converter module Positioner Type 6116 1 Balance beam Plunger coil 3 Permanent magnet 6 Flapper plate 7 Nozzle 8 Adapter (3766) 9 Adapter 10 O-ring Input signal 7 Supply air 11 Exhaust 13 Flame protection filter 14 Throttle with air supplied over the positioner Fig. 7 Functional diagram of version for positioner EB 6116 EN 15

Make sure the O-ring (10) to seal the converter housing is inserted correctly. 6.3 Electrical connection Connect as described in section.3 and Fig. 5. 6.4 Pneumatic connection Note! Generally, the pneumatic connection of the i/p converter is established by connecting it to the pneumatic input of the positioner. If attached directly to the Type 3766-000 Positioner (Fig. 8), the converter is connected via the bored screw with grommet (6) and the threaded bushing (5). The second screw (7) is used to vent the converter over the positioner housing. Before attaching the adapter (8) to the positioner, the M0 plug and the connecting nipple (input signal) must be removed. For Types 4765 and 3760 Positioners (Fig. 9 and 10), the 1 8 NPT threaded connection of the adapter (9) needs to be fitted with an appropriate cable gland and must be connected to the input connection (input signal 7) of the positioner with a pipe or hose. Try to keep the connection as short and small as possible, e.g. 6 x 1 cross section. The second bore (G ¼) serves as vent and needs to be equipped with the vent plug (11) included in the accessories. For all positioners, the connecting plate (1) must be removed from the bottom of the housing together with the sealing element (1.1) and replaced with the parts delivered as accessories. Make sure that the sealing element is positioned correctly. The filter must be located in front of the throttle belong to the connecting plate. 16 EB 6116 EN
