2. Short description
AUMA spur gearboxes are multi-turn gearboxes transmitting a rotary movement to
the valve.They are driven either via electric motor (by means of a multi-turn actuator)
or manually (via a handwheel).The drive axle operates at an offset to the output
drive axle.

4. Transport and storage
4.1. Transport
For transport to place of installation, use sturdy packaging.
Transport gearbox and actuator separately.
Suspended load!
Death or serious injury.
→Do NOT stand below suspended load.
→Fix ropes or slings on gearbox housing, NOT to handwheel, actuator, or actuator
controls.
→Check eyebolts for tight seat in housing (verify reach of the screw).
→Observe manufacturer specifications for fixing lifting straps and round slings.
→Respect total weight of combination (gearbox, actuator, actuator controls, output
drive).
→Eyebolts are exclusively permitted for the weight of the represented arrange-
ments of the respective sizes.
→Secure load against falling down, sliding or tilting.
→Perform lift trial at low height to eliminate any potential danger e.g. by tilting.
GSTI 25.1 and GSTI 30.1
Actuators for gearboxes GSTI 25.1 and GSTI 30.1 are always supplied separately
when leaving the factory and must be transported and lifted separately. Unless
specified otherwise by the customer, output drive types A and AF are mounted to
the gearbox. Sizes 25.1 and 30.1 leave the factory with fitted eyebolts.The gearbox
is either vertically suspended via round slings/lifting straps or horizontally via eyebolts.

GSTI 25.1 –GSTI 40.1 for use in nuclear power plants
(Inside/Outside Containment) Transport and storage

1. Prior to storage:
Protect uncoated surfaces, in particular the output drive parts and mounting
surface, with long-term corrosion protection agent.
2. At an interval of approx. 6 months:
Check for corrosion.If first signs of corrosion show, apply new corrosion protec-
tion.

Mounting positions Figure 8: MouMounting positions A –C
Information Refer to the technical data section at the end of the document for possible combina-
tions with multi-turn actuators.
Screws to multi-turn ac-
tuator Screws are included in the scope of delivery of the gearbox for mounting AUMA
multi-turn actuators.When mounting other multi-turn actuators, the screws might be
either too long or too short (insufficient reach of screws).
Risk of actuator falling off in case inappropriate screws used should shear.
Risk of death or serious injury!
→Check length of screws.
The reach of screws must be sufficient for the internal threads to ensure the
supporting strength of the multi-turn actuator and to accept the lateral forces due to
the applied torque.
Screws which are too long could make contact with the housing parts, presenting
the risk that the multi-turn actuator performs a radial shift with respect to the gearbox.
This can lead to shearing of the screws.
Mount input mounting
flange A flange is required for mounting a multi-turn actuator. Depending on the version,
the flange for mounting the multi-turn actuator is already fitted in the factory.
Figure 9: Mount flange to multi-turn gearbox
[1] Gearbox
[2] Parallel pin
[3] Input mounting flange
Assembly steps 1. Clean mounting faces, thoroughly degrease uncoated mounting surfaces.
2. Mount parallel pin [2].
3. Place input mounting flange [3] and fasten with screws.
4. Tighten screws crosswise with a torque according to table <Tightening torques
for screws> .
5. Place the multi-turn actuator on the spur gearbox and mount according to the
multi-turn actuator's operation instructions.Ensure that the spigot fits uniformly
in the recess and that the mounting faces are in complete contact.

6. Commissioning
6.1. Seating via multi-turn actuator
This chapter supplies basic information and instructions which should be considered
in addition to the operation instructions of the multi-turn actuator.
●The valve manufacturer has to determine whether the valve is limit or torque
seated.
●End position seating must be set in compliance with the operating instructions
pertaining to the multi-turn actuator.
●For limit seating, determine overrun, i.e. how much does the valve move after
the motor has been switched off?
●When setting the torque switching within the multi-turn actuator, make sure that
the tripping torque for both directions does not exceed the max. gearbox input
torque (refer to technical data or name plate).
●Set the torque switching within the multi-turn actuator to the following value to
prevent damage to the valve:
Tripping torque = valve torque/factor (refer to name plate)

7. Servicing and maintenance
Damage caused by inappropriate maintenance!
→Servicing and maintenance must be carried out exclusively by suitably qualified
personnel having been authorised by the end user or the contractor of the plant.
Therefore, we recommend contacting our service.
→Only perform servicing and maintenance tasks when the device is switched off.
AUMA
Service & Support AUMA offers extensive service such as servicing and maintenance as well as
customer product training.For the contact addresses, refer to our website
(www.auma.com).
7.1. Preventive measures for servicing and safe operation
●Before commissioning, perform visual inspection for grease leakage and paint
damage (corrosion).
●Thoroughly touch up any possible damage to paint. Original paint in small
quantities can be supplied by AUMA.
After six months and then once a year: Check gearbox for damage as well as for
grease and oil leakage.
7.2. Maintenance intervals
Recommendation for plants subject to strong vibration
●For plants subject to strong vibration, 6 months after commissioning and then
once a year: Check fastening screws between actuator and gearbox/valve for
tightness.If required, fasten screws while applying the tightening torques as
indicated in chapter <Assembly>.For screws sealed and secured with e.g.
thread sealing material, this action is not required.
Recommendation for grease change and seal replacement:
●If rarely operated (typically in buried service), the gearboxes are maintenance-
free.Grease change or re-lubrication is not necessary.
●If operated frequently (typically in modulating duty), we recommend changing
both grease and seals after 4 –6 years.
Gearing damage due to using inappropriate grease!
→Only use original lubricants supplied by AUMA.
→Do not mix lubricants.
When deployed in areas where dust formation represents a potential explosion
hazard, perform visual inspection for deposit of dirt or dust on a regular basis.Clean
devices if required.
Check gearbox for unusual running or grinding noise or vibration which might be an
indication of bearing or gear damage.
7.3. Disposal and recycling
Our devices have a long lifetime. However, they have to be replaced at one point in
time.The devices have a modular design and may, therefore, easily be separated
and sorted according to materials used, i.e.:
●Various metals
●Plastic materials
●Greases and oils
The following generally applies:
●Greases and oils are hazardous to water and must not be released into the
environment.
19
GSTI 25.1 –GSTI 40.1 for use in nuclear power plants
(Inside/Outside Containment) Servicing and maintenance

●Arrange for controlled waste disposal of the disassembled material or for sep-
arate recycling according to materials.
●Observe the national regulations for waste disposal.
