SRD991 Intelligent Positioner
These instructions are to be used as a guide for quick start-up. For more detailed information, please refer
to the standard documents “Master Instructions” and “Product Specification Sheet”. These can be found
on our Website.
1. MOUNTING TO ACTUATORS
During operation, the flat side of the spindle 9 on the back of the positioner must always point towards
the arrow 26. The working angle around this position is ±45º.

Any mechanical backlash may be source of poor control, oscillation and hunting as well as long duration of
Autostart. Please use only original mounting parts and ensure that they are correctly mounted and tighten.
By not using the original feedback lever or by using them in an inappropriate way, the performance of the
positioner may be compromised.

MOUNTING TO ROTARY ACTUATORS
• Do not tighten grub screw 4 against the thread
of spindle 9 ! (see next page).
• When in use the flat side of the spindle 9 must
move ( 0 ↔ 100%) in front of the arrow 26.
Direct Mounting
• When the product temperature rises, the drive
shaft 1 increases in length. Therefore, the rotary
adapter 3 must be mounted so that approx. 1
mm (0.04 in.) of clearance results between the
drive shaft 1 and the rotary adapter 3. This is
achieved by placing an appropriate number of
washers 5 on the feedback spindle 9 before
attaching the rotary adapter. Two washers
should result in a clearance of 1 mm.

2. CONNECTIONS
Check before mounting fittings and cable glands
that the threads are matching; otherwise the
housing can be damaged. The letter “G” on the
housing marks where the pneumatic connections
are in G 1/4 (otherwise NPT).

Connect earth cable to screw #1 (or screw #2 in
the electrical connection compartment).

WARNING
To avoid any personal injury resulting from bursting of parts, do not exceed maximum supply pressure of
positioner and actuator. To avoid any personal injury or property damage from sudden or fast movement,
during air connection: Do not put your finger or other part at any time inside the valve or in any
moving part of the actuator or in the feedback lever mechanism. Do not touch the rear part of the
positioner at any time. Connect air supply only after connections y1 (and y2 for double acting) are done.
Air supply (s): 1.4 to 6 bar (but not more than the max. pressure of actuator), free of oil, dust and water

4. START UP (Setting by means of local keys and LCD)
After mounting the positioner on the actuator, air
and electrical input connected, you can start-up
the SRD. The positioner can be adjusted by means
of a local key-pad and LCD.
WARNING
To avoid any personal injury or property damage
from sudden or fast movement, d uring conf iguratio n:
Do not put your finger or other part at any time
inside the valve or in any moving part of the
actuator or in the feedback lever mechanism.
Do not touch the rear part of the positioner at
any time.

5 TROUBLE SHOOTING (For more details see MI EVE0105 E)
Autostart err 1
Description of message / LCD text Remedy
Air supply too low Check air supply
Feedback lever (linear actuator) or Coupling (rotary
actuator) incorrectly linked. Potentiometer moves
out of operating range of ± 47° of 0° position
Coupling (rotary actuator) incorrectly linked
(R and L interchanged)
Pneumatic output to actuator closed or untight.
When direct mounting onto FlowTop or FlowPak,
the screw plug y1-d is not removed
Mechanical stops not determinable Check spring movement of actuator /
When using a booster or spool valve, no control
parameters can be determined, since air capacity
is too high
Control parameter too high since air capacity is too
high (in general, oscillation in valve movement)
Possibly incomprehensible configuration data Reset configuration, see Menu 9.1
Optionboard err
Description of message / LCD text Remedy
Configured status of the SRD deviates from
existing version (e.g. Option board has been
inserted subsequently)
Bad contact Connections to terminals interchanged
Defective Exchange option board
Ctrl diff error
Description of message / LCD text Remedy
Actuator problems (high friction or blocked) Check actuator
Insufficient air supply Check air supply / air filter
Insufficient parametes for position controls,
for example, amplification too small
IP module or pneumatic amplifier defect Check with Menu 7; replace if necessary
Determines only the mechanical stops of actuator/ valve
Recommended for standard applications
Optimized control behaviour compared to Standard Autostart
Dampened control behaviour for e.g. smaller actuators
Undampened control behaviour for e.g. larger actuators
