Valve damage for connection without controls!
→
NORM actuators require controls: Connect motor via actuator controls only
(reversing contactor circuit).
→
Observe the type of seating specified by the valve manufacturer.
→
The torque switches also serve the purpose of valve overload protection and must, therefore, also be connected for limit seating.
→
Observe wiring diagram.
Corrosion due to damage to paint finish!
→
After all assembly work at the device, check housing for damage to paint.
→
Carefully touch up damage to paint so that the initial delivery status is restored.
Original paint in small quantities can be supplied by AUMA.
Delay time
Limit and torque switches
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 < 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 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 TSC1, TSO1, LSC1, LSO1.
For switching off use the lagging contacts TSC, TSO, LSC, LSO.
Current type, mains voltage, mains frequency
Type of current, mains voltage and mains frequency must match the data on the motor name plate. Also refer to chapter <Identification>/<Name plate>.

Protection and sizing on site
Protection via thermal motor protection
●
●
For short-circuit protection and for disconnecting the actuator from the mains, fuses and disconnect switches have to be provided by the customer.
The current value for sizing the protection is derived from the current consumption of the motor (refer to motor name plate).
We recommend adapting the switchgear sizing to the max. current (I max
) and selecting and setting the overcurrent protection device in compliance with the indications in the electrical data sheet.
Version with thermoswitches as motor protection:
According to EN 60079-14, a thermal overcurrent protection device (e.g. motor protection switch) must be installed for explosion-proof actuators in addition to the thermoswitches.
Version with PTC thermistor:
PTC thermistors additionally require a suitable tripping device in the actuator controls.
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 rated current (I
N
) (refer to motor name plate 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 the connection of position transmitters, screened cables must be used.
Cable installation in accordance with EMC
●
●
●
●
●
Signal cables are susceptible to interference. Motor cables are interference sources.
Lay cables being susceptible to interference or sources of interference at the highest possible distance from each other.
The interference immunity of signal cables increases if the cables are laid close to the earth potential.
The interference immunity of network cables increases if the cables are laid close to the earth potential.
If possible, avoid laying long cables and make sure that they are installed in areas being subject to low interference.
Avoid parallel paths with little cable distance of cables being either susceptible to interference or interference sources.

Faults during commissioning
Table 18:
Faults during operation/commissioning
Fault Description/cause
Mechanical position indicator cannot be set.
Reduction gearing is not suitable for turns/stroke of the actuator.
In spite of correct setting of mechanical limit switching, actuator operates into the valve or actuator end position.
The overrun was not considered when setting the limit switching.
The overrun is generated by the inertia of both the actuator and the valve and the delay time of the actuator controls.
●
●
Remedy
Exchange reduction gearing.
Determine overrun: Overrun = travel covered from switching off until complete standstill.
Set limit switching again considering the overrun. (Turn handwheel back by the amount of the overrun)
Limit and/or torque switches do not trip.
Switch is defective or switch setting is incorrect.
Check setting, if required, reset end positions.
Refer to <Check switches> and replace the switches if required.
It is advised to check the actuator in the event of tripping failure, also refer to <Maintenance>.
Switch check
The black test buttons [1] and [2] are used for manual operation of the switches:
1.
Turn test button [1] in direction of the DSR/TSC (torque switch, clockwise closing) arrow: Torque switch CLOSED trips.
2.
Turn test button [2] in direction of the DÖL/TSO (torque switch, counterclockwise opening) arrow: Torque switch OPEN trips.
If the actuator is equipped with a DUO limit switching (option), the intermediate position switches WDR/LSA (DUO limit switching clockwise) and WDL/LSB (DUO limit switching counterclockwise) will be operated at the same time as the torque switches.
1.
Turn test button [1] in direction of the WSR/LSC (limit switch, clockwise closing) arrow: Limit switch CLOSED trips.
2.
Turn test button [2] in direction of the WÖL/LSO (limit switch, counterclockwise opening) arrow: Limit switch OPEN trips.
14.2.
Motor protection (thermal monitoring)
Possible causes for motor protection tripping:
Thermoswitches are provided in the motor winding to monitor the motor winding temperature. The thermoswitches trip as soon as the max. permissible winding temperature has been reached.
Overload, running time exceeded, max. number of starts exceeded, max. ambient temperature exceeded.
Thermoswitches may only be used to monitor the motor during standard operation. Switching off in case of DBE is not permitted!

15.1.
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, threaded plugs, blanking plugs, etc. have to be checked for correct fit 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 chapter <Assembly>.
When rarely operated: Perform test run.
15.2.
Maintenance
Manual operation During maintenance, the mechanical parts of the handwheel activation, in particular motor coupling and retaining spring, must be checked. Replace the parts in case of visible wear.
15.3.
Lubrication
●
In the factory, the gear housing is filled with grease.
●
Grease and seals are qualified.
●
We recommend replacing the seals when changing the grease.
●
Additional lubrication of the gear housing is not required during operation.
When detecting torque switching failure (tripping failure) during operation, the actuator should be subjected to unscheduled inspection and maintenance. If applicable, damaged components must be repaired or replaced. Decision whether the actuator can resume operation will be taken on the basis of test results and functional tests following corrective maintenance.
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.:
●
●
●
Electronic scrap
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.
