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
WAR N ING
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,

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”.

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.

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.

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.

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.
