5.3.1.1 Actuator (with coupling): mount
Unbored couplings or couplings with pilot bore must be machined to match the valve
shaft prior to mounting the actuator to the valve (e.g. with bore and keyway, two-flat or
square bore).
Assemble valve and actuator in the same end position. As standard, the actuator is supplied in end position CLOSED.
a) Recommended mounting position for butterfly valves: End position CLOSED.
b) Recommended mounting position for ball valves: End position OPEN.
We recommend applying liquid thread sealing material to the screws to avoid
contact corrosion.
Assembly steps 1. If required, move actuator in same end position as valve using the handwheel.
2. Clean mounting faces, thoroughly degrease uncoated mounting surfaces.
3. Apply a small quantity of grease to the valve shaft [2].
4. Place coupling [1] onto valve shaft [2] and secure against axial slipping by using a
grub screw [3] or a clamping washer and a screw with curved spring lock washer
[4]. Observe dimensions X, Y or L. Refer to following picture and table Mounting

6.1 Basic information
WARNING
Electric shock due to presence of hazardous voltage!
Failure to observe this warning could result in death, serious injury, or property damage.
&agrave; The electrical connection must be carried out exclusively by suitably qualified personnel.
&agrave; Prior to connection, heed basic information contained in this chapter.
Wiring diagram/terminal The pertaining wiring diagram/terminal plan (in German or English) is attached to the
plan device in a weather-proof bag, together with these operation instructions. It can also
be requested from AUMA when indicating the order number (refer to name plate) or
downloaded directly from our Website (http://www.auma.com).
NOTICE
Valve damage when connecting to actuator controls!
&agrave; NORM actuators require actuator controls: Connect motor via actuator controls
only (reversing contactor circuit).
&agrave; Respect the type of seating specified by the valve manufacturer.
&agrave; The torque switches also serve the purpose of valve overload protection and must,
therefore, also be connected for limit seating.
&agrave; Heed wiring diagram.
Delay time The delay time is the time from the tripping of the limit or torque switches to the motor
power being switched off. To protect the valve and the actuator, we recommend a
delay time &lt; 50 ms. Longer delay times are possible provided operating time, output
drive type, valve type, and type of installation are considered. We recommend switching off the corresponding contactor directly by limit or torque switch.
Limit and torque switches Limit and torque switches can be provided as single, tandem, or triple switches. Only
the same potential can be switched on the two circuits (NC/NO contact) of each single
switch. If different potentials are to be switched simultaneously, tandem switches or
triple switches are required. When using tandem/triple switches:
•
For signalling use the leading contacts DSR1/TSC1, DOEL1/TSO1, WSR1/LSC1,
WOEL1/LSO1.
•
For switching off use the lagging contacts DSR/TSC, DOEL/TSO, WSR/LSC,
WOEL/LSO.
Current type, mains Type of current, mains voltage and mains frequency must match the data on the motor
voltage, mains frequency name plate. Refer to Motor name plate [} 9].

Protection and sizing on For short-circuit protection and for disconnecting the actuator from the mains, fuses
site and disconnect switches or circuit breakers have to be provided by the customer.
17
Electrical connection
The current value for sizing the protection is derived from the current consumption of
the motor (refer to Motor name plate [} 9]).
We recommend adapting the switchgear sizing to the max. current (Imax) and selecting
and setting the overcurrent protection device in compliance with the indications in the
electrical data sheet.
Safety standards Safety measures and safety equipment must comply with the respectively valid national on site specifications. All externally connected devices shall comply with the relevant safety standards applicable for the place of installation.
Connecting cables, cable •
glands, reducers, blanking
plugs
•
We recommend using connecting cables and connecting terminals according to
nominal current (IN). (Refer to Motor name plate [} 9] or electrical data sheet.)
For device insulation, appropriate (voltage-proof) cables must be used. Specify
cables for the highest occurring rated voltage.
•
To avoid contact corrosion, we recommend the use of sealing agents for cable
glands and blanking plugs made of metal.
•
Use connecting cable with appropriate minimum rated temperature.
•
For connecting cables exposed to UV radiation (outdoor installation), use UV resistant cables.
•
For connecting position transmitters, only use screened cables.

10.1 End stops in part-turn actuator
The internal end stops limit the swing angle. They protect the valve in case of limit
switching failure during motor operation and serve the purpose as limitation for manual
operation via handwheel. They may not be used for torque tripping in end positions
during standard operation.
End stop setting is generally performed by the valve manufacturer prior to installing
the valve into the pipework.
CAUTION
Exposed, rotating parts (discs/balls) at the valve!
Pinching and damage by valve or actuator.
&agrave; End stops should be set by suitably qualified personnel only.
&agrave; Never completely remove the setting screws [2] and [4] to avoid grease leakage.
&agrave; Observe dimension Tmin.
The swing angle set in the factory is indicated on the name plate:

13.1 Preventive measures for servicing and safe operation
The following actions are required to ensure safe device function during operation:
6 months after commissioning and then once a year
•
Carry out visual inspection:
Cable entries, cable glands, blanking plugs, etc. have to be checked for correct
tightness and sealing. If required, tighten cable glands and blanking plugs with
torque in compliance with the manufacturer's specifications.
Check actuator for damage as well as for grease or oil leakage.
•
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 fastening screws between actuator and gearbox/valve for tightness. If required, fasten screws while applying the tightening torques as indicated in Tightening torques for screws [} 46] chapter.
•
When rarely operated: Perform test run.
For enclosure protection IP68
After immersion:
•
Check actuator.
•
In case of ingress of water, locate leaks and repair. Dry device correctly and check
for proper function.
13.2 Maintenance
Manual operation During maintenance, the mechanical parts of the handwheel activation, in particular
motor coupling, must be checked. Replace the parts in case of visible wear.
Lubrication •
In the factory, the gear housing is filled with grease.
•
Additional lubrication of the gear housing is not required during operation.
•
Grease change is performed during maintenance
•
–
Generally after 4 to 6 years for modulating duty.
