1. Introduction

! DANGER

EQUIPMENT OPERATION HAZARD

Accident Prevention

The connected instrument contains mechanical moved parts, e.g. feedback lever, which could cause injuries. The operators must be instructed accordingly.

Electrical Safety

This instrument satisfies the conditions for safety class III, over-voltage category I according to EN 61010-1 or IEC1010-1.

Any work on electrical parts is done by a qualified personnel if any supply is connected to the instrument. The instrument is used for its designated purpose and connected in accordance with its connection diagram. Locally applicable installation regulations for electrical equipment is observed, e.g. in the Federal Republic of Germany DIN VDE 0100 respectively DIN VDE 0800. The instrument is operated with safety extra low voltage SELV or SELV-E. Safety precautions taken in the instrument may be rendered ineffectual if the instrument is not operated in accordance with the Master Instructions. Limitation of power supplies for fire protection must be observed due to EN 61010-1, appendix F or IEC 1010-1.

Failure to follow these instructions can result in death or serious injury.

16

2. Method Of Operation

General

The intelligent positioner SRD998 1 and the pneumatic actuator 2 form a control loop with the set point value w (from master controller or control system), the output pressure y and the position x of the actuator on valve 3.

Figure 6. Intelligent Positioner SRD 998 - HART Version

For the supply air, we recommend the FRS** filter regulator.

The positioner can be attached to both linear and rotary actuators. Actuators with spring force are controlled by a single acting positioner. Actuators without spring force are controlled by a double acting positioner.

Using HART, the positioner can be operated locally by means of Rotary Selector and LCD, Hand Held Terminal, remotely via PC-based configuration like FDT/DTM or a corresponding control system, e.g. I/A Series System

! WARNING

RISK OF IMPROPER INSTALLATION

For the supply air, we recommend the FRS** filter regulator.

Failure to follow these instructions can result in death or serious injury.

Operation

With the intelligent positioner with input signal 4-20 mA and superimposed HART signal, the supply takes place via the power signal adjacent to the input as shown in Figure 7. By means of voltage converter 7, derivation of the internal supply of the electronics takes place. The current value is measured, in A/D transformer 9 converted, and directed via switch 10 to digital controller 11. The output of controller 11 drives the electro-pneumatic converter (IP-module) 12,

MI EVE0108 – November 2019

2. Method Of Operation

controlling a pre-amplifier 13, the single acting (or double acting) pneumatic power amplifier 14. The output of the amplifier 14 is the output pressure y to the actuator.

The pneumatic amplifiers are supplied with supply air s1.4 to 6 bar (20 to 90 psig) or 1.4 to 10 bar (20 to 145 psi). The position x of the actuator is sent to the control unit 11 by the position sensor (conductive plastic potentiometer) 15. Optional gauges 16 enable additional diagnostic indications. Adjusting, start-up of the positioner as well as the demand for internal information can be made using the Rotary Selector 17, with indication given by LCD 18.

3. Operating Modes

Operation of the positioner is divided into individual operating modes. Operating modes may change depending on, for example, key commands or internal calculations.

Initialize

Upon power-up, several self-tests are conducted. If no error is detected the device moves to OUT OF SERVICE, if it is still in a delivery condition; AUTOSTART is performed. If AUTOSTART was done already, the device will go to IN OPERATION.

If issues are detected, the code of the self-test will remain. If an error is detected after reset, see Chapter 11, “Troubleshooting” or contact Global Customer Support.

Device Inoperable

If the LCD shows a message, a device issue is signaled. These issues are detected during cyclical self test.

The device can no longer be operated. This could be caused by a jammed Rotary Selector, invalid program memory, etc. (see Chapter 11, “Troubleshooting”). If a device error is detected continuously, contact Global Customer Support.

In Operation

After performing an AUTOSTART, the device moves to IN OPERATION and will always, even after restarting or resetting, move back to the safety position (de-energized valve position) or FAILSAFE. If set point values are fed via communication, the SRD will go to IN OPERATION.

Out of Service

The SRD in delivered condition is configured in such a way that it will remain OUT OF SERVICE after power-up until moving to IN OPERATION via the manually initiated function AUTOSTART. In the device state OUT OF SERVICE, the menu entering mode remains active at all times. If a device has been IN OPERATION already and is removed from an actuator and mounted to another, we recommend taking the device out of operation via “M 10.1 Reset Configuration to Ex Factory Settings” prior to disconnecting the device from the first actuator. This enables the next actuator to be started in the delivered condition. For more information, see “M 10.1 Reset Configuration to Ex Factory Settings”.

Calibrate

During an AUTOSTART function the device is in condition CALIBRATION. The actuator is moved up and downward several times, and the device could be busy for a few minutes. Subsequently, the device moves to IN OPERATION.

19

MI EVE0108 – November 2019

3. Operating Modes

Messages

The SRD continuously supervises important device functions. In the case that limit values are exceeded or operational problems occur, messages are signaled via the LCD. The message with the highest priority will be indicated first. With rotary selector other messages can be called up.

For more information, see Chapter 11, “Troubleshooting”. LCD description and possible operator interventions are described in Chapter 8, “Start Up”.

Use:

attachment kit EBZG -H for a cast yoke, or

attachment kit EBZG -K for a pillar yoke and

the side outputs I (or I and II)

NOTICE

HAZARD OF EQUIPMENT DAMAGE

Pneumatic connections: Do not use Teflon tape for sealant. The fine fibers could disturb the function of the SRD. Use only Loctite® #243 for sealant (apply only to male thread).

Failure to follow these instructions can result in equipment damage.

Screw-type glands for electrical connections are positioned on the side. Device is shipped with a closing sticker; remove sticker and mount a cable gland or, if unused, a closing plug.

Preparation of the Positioner

Rotate the shaft stub of shaft 9 so that the flat on the shaft stub is perpendicular to the arrow 26 on the housing at mid travel range. Fasten the feedback lever A to the shaft by means of spring washer and nut M8.

Figure 11. Preparation of Positioner - Left Hand

5. Mounting to Actuators

MI EVE0108 – November 2019

Preparation of the Actuator

Screw the carrier bolt to the stem connector and lock it by means of a counter nut. A carrier bolt with an adjustable length is used to be able to screw on various coupling pieces.

Figure 12. Preparation of the Actuator - Left Hand

It consists of a stud S (size M6), which is screwed into the coupling piece K (with 3 mm Allen key) and locked with a lock nut 1. The threaded sleeve H is screwed onto it and locked with a lock nut 2. Ensure that the bolt is adjusted to a suitable length. Fasten the mounting bracket to the left side of the yoke.

Remember:

for a cast yoke use a screw M8 x 30

for a pillar yoke use two U-bolts and four nuts

Mounting of the Positioner

Fasten the positioner to the mounting bracket using two spring washers and two screws M8 x 80. Note the carrier bolt B is in the slot of the feedback lever A and the compensating spring F touches the carrier bolt.

Figure 13. Feedback Lever

For optimum utilization of the positioner operating range, we recommend that the arrangement is adjusted according to the following procedure before fixing.

At an actuator position in the middle of travel range, the feedback lever position must be perpendicular to the actuator stem and the angle range must be between ±10° and ±45°.

Fasten the positioner to the mounting bracket so that a suitable angle range is selected. We recommend that the pneumatic and electrical connections are made after adjusting the position.

5. Mounting to Actuators

Attachment of the positioner to the actuator is made to the right using the mounting bracket and feedback lever for a NAMUR mount.

Use:

the attachment kit EBZG -H for a cast yoke

the attachment kit EBZG -K for a pillar yoke

the side outputs I (or I and II)

NOTICE

HAZARD OF EQUIPMENT DAMAGE

Pneumatic connections: Do not use Teflon tape for sealant. The fine fibers could disturb the function of the SRD. Use only Loctite® #243 for sealant (apply only to male thread).

Failure to follow these instructions can result in equipment damage.

Screw-type glands for electrical connections are positioned on the side. Device is shipped with a closing sticker; remove sticker and mount a cable gland or, if unused, a closing plug.

Preparation of the Positioner

Rotate the shaft stub of shaft 9 so that the flat on the shaft stub is perpendicular to the arrow 26 on the housing at mid travel range. Fasten the feedback lever A to the shaft by means of spring washer and nut M8.

Preparation of the Actuator

Screw the carrier bolt to the stem connector and lock it by means of a counter nut. A carrier bolt with an adjustable length is used to be able to screw on various coupling pieces.

It consists of a stud S (size M6), which is screwed into the coupling piece K (with 3 mm Allen key) and locked with a lock nut 1. The threaded sleeve H is screwed onto it and locked with a lock nut 2. Ensure that the bolt is adjusted to the right length. Fasten the mounting bracket to the left side of the yoke. For a cast yoke use a screw M8 x 30, for a pillar yoke use two U-bolts and four nuts.

Figure 17. Preparation of the actuator - Right Hand

Mounting of the Positioner

Fasten the positioner to the mounting bracket using two spring washers and two screws M8 x 80. Note the carrier bolt B is in the slot of the feedback lever A and the compensating spring F touches the carrier bolt.

Figure 18. Feedback Lever - Right Hand

For optimum utilization of the positioner operating range, we recommend the arrangement be adjusted according to the following procedure before fixing.

At an actuator position in the middle of travel range, the feedback lever position must be perpendicular to the actuator stem and the angle range must be between ±10° and ±45°.

Fasten the positioner to the mounting bracket so that a suitable angle range is selected.

We recommend that the pneumatic and electrical connections are made after adjusting the position.
