Operation instructions
Safety instructions
1.1 Range of application
AUMA actuators are designed for the operation of industrial valves, e.g.
globe valves, gate valves, butterfly valves and ball valves.
For other applications, please consult us. AUMA is not liable for any possible damages resulting from use in other than the designated applications.
Such risk lies entirely with the user.
Observance of these operation instructions is considered as part of the actuator’s designated use.
1.2 Short description
AUMA multi-turn actuators type SARV 07.1 - SARV 10.1 have a modular
design. Multi-turn actuators are driven by an electric motor and controlled
with the electronic controls AUMA VARIOMATIC, which are included in the
scope of supply. The limitation of travel is realised via limit switches in both
end positions. Torque seating is also possible in both end positions. The
type of seating is stated by the valve manufacturer.
1.3 Commissioning
(electrical connection)

Supply command signal to any value between 0/4 and 20 mA.
Set dead band with potentiometer ∆E (P9) so that multi-turn actuator does
not readjust after a single control operation:
- turning clockwise results in reduced sensitivity (dead band increased)
When setting E the following must be observed by all
means:
If the number of starts is too high, this can lead to
unnecessary wear at the valve and actuator. Therefore the
highest possible sensitivity (dead band) which is permitted
for the process must be set.
To prevent an exceeding of the max. permissible number of starts
(1 500 c/h) in extreme cases, a time delay between 0,5 s (left stop) and
10s (right stop) may be set with potentiometer t-off (R88).

Check on the logic board whether the DIP switch S1, pos. 7 (nominal
output speed) is in position ”OFF”. If necessary, correct the switch position
(see clause 14, pages 18/19).
Set the potentiometer ”OPERATING TIME” (figure V, page 23) on the
logic board to the fully clockwise position (max. speed) to make use of the
entire range of operating time. If the minimal operating time (max. speed)
has to be limited to a higher value as the operating time possible by the
actuator (see technical data sheet), set potentiometer to this value (e.g. to
avoid water hammer).
When using the option positioner (see clause 15, page 20) set the selector
switch S2-2.2 (figure W) on the speed-interface board to position
‘positioner’. For all other versions the switch S2-2.2 has to be set to position
‘speed-interface board’.

Operation instructions
Analogue
nominal operating time E3:
The analogue operating time range E3 (refer to wiring diagram CI S...KMS
14TP...) can be set with the switch S1-2.2 (figure W) to either 0 - 20 mA or
4 - 20 mA.
After a change, adjustment of the max. value (20 mA) is necessary.
The adjustment is performed as follows:
Connection of 24 V DC +/- 10 % to the analogue input of the
speed-interface board (see wiring diagram CI S...KMS 14TP...)
max. current input ≤ 30mA
Connection of 20 mA at nominal operating time E3 of the speed-interface
board (see wiring diagram CI S...KMS 14TP...)
Measure voltage between MP1 and MP2 (figure W).
Adjust the voltage to 10,00 V +/- 0,01 V by using the potentiometer R16
(figure W).
.
.
..
Binary
nominal operating n1, n2
Two inputs are available for the setting of the operating time via binary signals.
The adjustment of the two operating times is performed as follows:
Control of the binary nominal operating time n1 by
Connection of 24 V DC to the binary input n1 of the speed-interface board
(see wiring diagram CI S...KMS 14TP...)
A visual check of the connected signal with LED V4 is possible (figure W).
The setting of the operating time is done via potentiometer R9 (figure W),
clockwise rotations equals higher speed = shorter operating time.
.
.
.
.
Control of the binary nominal operating time n2 by
Connection of 24 V DC to the binary input n2 of the speed-interface board
(see wiring diagram CI S...KMS 14TP...)
A visual check of the connected signal with LED V6 is possible (figure W).
The setting of the operating time is done via potentiometer R10 (figure
W), clockwise rotations equals higher speed = shorter operating time.
.
.
.
.
During simultaneous control of n1 and n2, the shortest
operating time has priority.
Without control of n1 and n2, the max. operating time is
available.
When operated via local controls, the actuator always runs
with max. speed (shortest operating time).
Control of the set speed (operating time) is only possible
via REMOTE commands.

16.3 Further functions of the speed-interface board in conjunction with the positioner (option)
Remote change-over of the nominal operating time
This function is only possible in combination with the
analogue or binary nominal operating time (selector switch
S2-2.2 in position ‘positioner’, figure W).
The nominal operating time can be changed between the
operating time determined by the positioner and by the customer via the
speed-interface board with a + 24 V DC signal from Remote.

19. Maintenance
Operation instructions
After commissioning, check for damages on paint of multi-turn actuator. Do
a thorough touch-up to prevent corrosion. Original paint in small quantities
can be supplied by AUMA.
AUMA multi-turn actuators require very little maintenance.
Precondition for reliable service is correct commissioning.
Seals made of elastomers are subject to aging and must therefore regularly
be checked and, if necessary, exchanged.
It is also very important that the O-rings at the covers are placed correctly
and cable glands fastened firmly to prevent ingress of dirt or water.
.
.
.
We recommend:
If operated seldom, perform a test run about every 6 months. This assures
that the actuator is always ready to operate.
Approximately six months after commissioning and then every year check
bolts between actuator and valve/gearbox for tightness. If required,
re-tighten applying the torques given in table 1, page 7.
At intervals of approx. 6 months press in several squirts of ball bearing
grease at the lubrication nipple with grease gun.
Lubrication of the valve stem must be done separately.
The gear housing is filled with lubricant in the factory.
A grease change is recommended after 4 - 6 years.
