COMMUNICATION PROTOCOLS

2.1 General

This manual incorporates Installation, Maintenance and Operation Instructions for the Metso ND9000 and ND intelligent valve controller. The ND9000 and ND7000 may be used with either cylinder or diaphragm type pneumatic actuators for rotary or linear valves.

2.2 Technical description

ND9000H and ND7000H The ND9000H and ND7000H are a 4–20 mA loop-powered microcontroller-based intelligent valve controllers. The devices operate even at 3.6 mA input signal and communi- cates via HART. ND9000F The ND9000F is a fieldbus powered microcontroller-based intelligent valve controller. ND9000P The ND9000P is a fieldbus powered microcontroller-based intelligent valve controller. All versions All devices contain a Local User Interface enabling local configuration. Independently from the communication protocol, the valve position is controlled by the powerful 32-bit microcontrol- ler. The measurements include:  Input signal  Valve position with contactless sensor  Actuator pressures, 2 independent measurements  Supply pressure  Spool valve position  Device temperature Advanced self-diagnostics guarantees that all measure- ments operate correctly. Failure of one measurement does not cause the valve to fail if the input signal and position measurements are operating correctly. After connections of electric signal and pneumatic supply the micro controller (μC) reads the input signal, position sensor (α), pressure sensors (Ps, P1, P2) and spool position sensor (SPS). A differ- ence between input signal and position sensor (α) measure- ment is detected by the control algorithm inside the μC. The μC calculates a new value for prestage (PR) coil current based on the information from the input signal and from the sensors. Changed current to the PR changes the pilot pressure to the spool valve. Reduced pilot pressure moves the spool and the actuator pressures change accordingly. The spool opens the flow to the driving side of the double diaphragm actuator and opens the flow out from the other

NOTE:

The selection and use of the valve controller in a specific application requires close consideration of detailed aspects. Due to the nature of the product, this manual cannot cover all the likely situations that may occur when installing, using or servicing the valve controller. If you are uncertain about the use of the controller or its suitability for your intended use, please contact Metso’s Automation business for more information.

side of the actuator. The increasing pressure will move the diaphragm piston. The actuator and feedback shaft rotate clockwise. The position sensor (α) measures the rotation for the μC. The μC using control algorithm modulates the PR- current from the steady state value until a new position of the actuator according to the input signal is reached.

2.3 Markings

The valve controller is equipped with an identification plate (Fig. 2).

Identification plate markings include:

 Type designation of the valve controller  Revision number  Enclosure class  Input signal (voltage range)  Input resistance  Maximum supply voltage  Operational temperature  Supply pressure range  Contact details of the manufacturer  CE mark  Manufacturing serial number TTYYWWNNNN*) *) Manufacturing serial number explained: TT= device and factory sign YY= year of manufacturing WW = week of manufacturing NNNN = consecutive number Example: PH13011234 = controller, year 2013, week 1, con- secutive number 1234.

Note, that in ND9200 and ND9300 models there may have two identification plates if there is double approval (type ND92_XE1 or ND93_XE1). When device is installed to Ed i or Ex d area, remove identifi- cation plate which is not valid. If device is installed to Ex d area, it can't be installed to Ex i area even that identification plate would be changed. See Chapter 15 for all ID plates.

3 TRANSPORTATION, RECEPTION AND

STORAGE

The valve controller is a sophisticated instrument, handle it with care.

 Check the controller for any damage that may have occurred during transportation.  Store the uninstalled controller preferably indoors, keep it away from rain and dust.  Do not unpack the device until installing it.  Do not drop or knock the controller.  Keep the flow ports and cable glands plugged until installing.  Follow instructions elsewhere in this manual.

4 MOUNTING

4.1 General

If the ND is supplied with valve and actuator, the tubes are mounted and the ND adjusted in accordance with the cus- tomer’s specifications. If the controller is ordered separately, the mounting parts for the assembly must be ordered at the same time. Sample order: (B1CU13)-Z-ND9_06HN Shaft coupling alternatives for the controller for Metso actuators are shown in Fig. 6.

4.2 For mounting parts for Metso actuators,

see 12.5–12.10.Mounting on Metso

actuators

See figures in Section 12.6–12.7. ND9100, ND9400, ND  Mount the H-shaped coupling (47) to the shaft. Apply the thread-locking compound to the screw (48) and tighten firmly.  Remove all protective plastic plugs from the pneu- matic connections (5 pcs.). Mount the metal plugs (54) with sealant to the unused controller connec- tions at the bottom of the controller.  BJ and other single acting actuators: mount a metal plug (53) with sealant to the C1 connection.  Set the direction arrow of the actuator in the direc- tion of the valve closure member and attach the ear (2) to the indicator cover in the position shown in Section 12.6-12.7. Secure the screw of the ear using e.g. Loctite and tighten firmly.  Attach the bracket (1) to the ND.  Attach the bracket (1) to the actuator. The shaft cou- pling of the ND must fit into the ear (2) so that the pointer of the shaft washer (16) is located in the posi- tion shown in Fig. 5.

Intrinsic Safety (Ex i) WARNING (ND9100, ND9200, ND9300 and ND7100): Ensure that the complete installation and wiring is intrinsically safe before operating the device! The equipment must be connected via a certified Zener barrier placed outside the hazardous area.

Ex WARNING (ND9200, ND7200) : Electrostatic charge hazard! The windows and identification plate are non-conductive. Clean with a damp cloth only!

Ex WARNING (ND9100, ND7100) : For use in the presence of combustible dust. Device shall not be subjected to a prolific charge gen- erating mechanism.

Ex WARNING (ND9000, ND7000): Accumulation of dust shall be avoided!

Ex d WARNING (ND9200, ND7200, ND9300): Use a cable gland and blind plug with suitable Ex d certification. For ambient temperature over 70 °C / 158 °F use a heat resistant cable and cable gland suitable for at least 90 °C / 194 °F.

Ex n WARNING (ND9100, ND9200, ND9300 and ND7100): At an ambient temperature ≥ +70 °C / 158 °F, the tem- perature rating of selected connection cable shall be in accordance with the maximum ambient tempera- ture range. Selected cable gland shall not invalidate the type of protection.

Ex i WARNING (ND9100, ND9200, ND9300 and ND7100): At an ambient temperature ≥ +70 °C / 158 °F, the tem- perature rating of selected connection cable shall be in accordance with the maximum ambient tempera- ture range.

Ex NOTE: Follow the standards EN/IEC 60079-14 when installing the equipment and and EN/IEC 60079-25 when connecting Ex i interfaces.

NOTE:

The enclosure of ND9000 and ND7000 intelligent valve controller meets the IP66 protection class according to EN 60529 in any position when the cable entry is plugged according to IP66. Based on good mounting practice, the recommended mounting position is electrical connections placed down- wards. This recommendation is shown in our mounting position coding for control valves. If these requirements are not fulfilled, and the cable gland is leaking and the leakage is damaging valve controller or other electrical instrumentation, our warranty is not valid.

NOTE: Make sure the mounting of the device and the valve assembly is suitable for the weight of the assembly.

ND9200, ND7200, ND

 Make sure the mounting bracket is suitable for the weight of the controller. See detailed weight infor- mation in Section 2.4.  ND9300: Extra mounting holes exist in the housing for additional support. See dimension drawings for ND9300 in Chapter 13. The use of this extra support is mandatory in addition to the standard face.  ND9300: Due to the extra weight of stainless steel version and/or possible heavy vibration, make sure there are proper supports in the pipeline to hold the weight of the valve assembly.  Mount the H-shaped coupling (47) to the shaft. Apply the thread-locking compound to the screw (48) and tighten firmly.  Remove the protective plastic plugs from pneumatic connections C2, S and C1. Leave the metal plugs (54) in the unused connections at the bottom of the con- troller.  BJ and other single acting actuators: install a metal plug (53) with sealant to the C1 connection.  Set the direction arrow of the actuator in the direc- tion of the valve closure member and attach the ear (2) to the indicator cover in the position shown in Section 12.6-12.7. Secure the screw of the ear using e.g. Loctite and tighten firmly.  Attach the bracket (1) to the controller.  Attach the bracket (1) to the actuator. The shaft cou- pling of the controller must fit into the ear (2) so that the pointer is located in the position shown in Fig. 5.

mounting face

See figure in Section 12. ND9100, ND9400, ND  Attach the feedback arm with spacer to the valve controller shaft. Note the position of the mark on the shaft as in 12.10. Apply thread locking compound to the screws and tighten firmly. Attach the spring to the feedback arm as shown in Section 12.10.  Mount the valve controller mounting bracket loosely to the yoke of the actuator.  Remove all plastic plugs from all actuator connec- tions. Mount the metal plugs (54) with sealant to the unused controller connections at the bottom of the controller.  Mount the valve controller loosely to the mounting bracket guiding the pin on the actuator stem to the slot of the feedback arm.  Align the bracket and the valve controller with the actuator stem and adjust their position so that the feedback arm is approximately at a 90° angle to the actuator stem (in the mid-stroke position).  Tighten the valve controller mounting bracket screws.  Adjust the distance of the valve controller to the pin on the actuator stem so that the pin stays in the lever slot at full stroke. Ensure also that the maximum angle of the lever does not exceed 45° in either direction. Maximum allowed travel of the lever is shown in Section 12.10. Best control performance is achieved when the feedback lever utilises the maxi- mum allowed angle (±45° from horizontal position). The whole range should be at least 45°.  Make sure that the valve controller is in right angle and tighten all the mounting bolts.  Ensure that the valve controller complies with previ- ous steps. Check that the actuator pin does not touch the valve controller case throughout the entire stroke of the actuator. If the actuator pin is too long it may be cut to size.  Apply grease (Molykote or equivalent) to the contact surfaces of the actuator pin and the feedback arm to reduce wear. ND9200, ND7200, ND  Make sure the mounting bracket is suitable for the weight of the controller. See detailed weight infor- mation in Section 2.4.  ND9300: Extra mounting holes exist in the housing for additional support. See dimension drawings for ND9300 in Chapter 13.

4.5 Electrical connections

ND9000H, ND7000H

The ND9000H and ND7000H is powered by a standard 4– mA current loop that also functions as a carrier to the HART communication.

The input signal cable is led through a

 M20 x 1.5 cable gland, or  1/2 NPT cable gland (U, E2)

Connect the conductors to the terminal strip as shown in Fig. 9. It is recommended that the earthing of the input cable shield be carried out from the DCS end only.

The position transmitter is connected to 2-pole terminal PT as shown in Fig. 9. The position transmitter needs an exter- nal power supply. The ND9000H / ND7000H and the posi- tion transmitter circuits are galvanically isolated and withstand a 600 V AC voltage.

ND9000F, ND9000P

The ND9000F is powered by F OUNDATION fieldbus (IEC 61158-2). The ND9000P is powered by Profibus PA (IEC 61158-2). The same bus cable is used also for the fieldbus communi- cation. The bus cable is led through a  M20 x 1.5 cable gland, or  1/2 NPT cable gland (U, E2) Connect the conductors to the terminal strip as shown in Fig. 10. Reverse polarity protection permits connection of the bus cables in any order. The cable shield can be grounded by connecting the shield to the earth connection screw. The shield can be left uncon- nected by using the empty terminal.

Please note following before mounting the cover of the valve controller:  Attach the LUI (223) cabling to the sticker on the reverse side of the LUI. Check that the cabling does not get squeezed by the electronics cover (39) or the device cover (100).  Check using a feeler gauge that the clearance between the position indicator (109) and the elec- tronics cover is 1 mm.

NOTE:

The ND9000H and ND700H equal a load of 485 Ω in the current loop.
