1.3 Applications in Ex zone 22 (option)
Actuators of the indicated series basically meet the requirements for applications in
dust hazardous locations of ZONE 22 in compliance with the ATEX directive 94/9/EC.
The actuators are designed to meet enclosure protection IP 68 and fulfil the
requirements of EN 50281-1-1:1998 section 6 - Electrical apparatus for use in
presence of combustible dust, requirements for category 3 electrical equipment -
protected by enclosures.
To comply with all requirements of EN 50281-1-1:1998, it is imperative that the
following points are observed:
●Incompliance with theATEX directive94/9/EC,the actuatorsmust beequipped
with an additional identification –II3D IP6X T150 °C.
●The maximum surface temperature of the actuators, based on an ambient
temperature of +40 °C in accordance with EN 50281-1-1 section 10.4, is +150
°C.In accordance with section 10.4, an increased dust deposit on the equipment
was not considered for the determination of the maximum surface temperature.

AC 01.2 Intrusive Identification

A multi-turn actuator is an actuator which transmits to the valve a torque for at least
one full revolution.It is capable of withstanding thrust.
AUMA multi-turn actuators are driven by an electric motor and are capable of
withstanding thrust in combination with output drive type A. For manual operation,
a handwheel is provided.Switching off in end positions may be either by limit or
torque seating. Controls are required to operate or process the actuator signals.
Actuator controls TheAUMATIC actuatorcontrols are used to operate AUMA actuators and are supplied
ready for use.The controls may be mounted directly to the actuator or separately
on a wall bracket.
The functions of the AUMATIC controls include standard valve control in OPEN -
CLOSE duty, positioning, process control, logging of operating data right through to
diagnostic functions.
Local controls/AUMA
ToolSuite Operation, setting, and display can be performed on site directly at the controls.
When set to local control, it is possible to
●operate the actuator via the local controls (push buttons and display) and perform
settings (contents of these instructions).
●readin or out data or modify and savesettings via the AUMAToolSuite software
(option), using a computer (laptop or PC).The connection between computer
and AUMATIC is wireless via Bluetooth interface (not included in these instruc-
tions).
Intrusive - Non-Intrusive ●Intrusive version (control unit: electromechanical):
Limit and torque setting is performed via switches in the actuator.
●Non-Intrusive version (control unit: electronic):
Limit and torque setting is performed via the controls, actuator and controls
housings do not have to be opened.For this purpose, the actuator is equipped
with an MWG (magnetic limit and torque transmitter), also supplying analogue
torque feedback signals/torque indication and analogue position feedback si-
gnals/position indication.

earthed star point and a maximum voltage of 690 V AC. Use in IT networks is
permitted while observing the respective <Protection on site> for for maiximum supply
voltages of 600V AC.
Protection on site 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 values for respective sizing is derived from the current consumption of
themotor (referto electricaldata sheet) plus thecurrent consumption of the controls.

If controls are mounted separately from actuator (controls on wall bracket):Consider
length and cross section of connecting cable when defining the protection required.
Use appropriate insulation monitors when working in power installations, for example
an insulation monitor measuring the pulse code.
Power supply for the
controls (electronics) In case of external supply of the controls (electronics):The external power supply
must have a reinforced insulation against the mains voltage in accordance with IEC
61010-1 and may only be supplied by a circuit limited to 150 VA in accordance with
IEC 61010-1.
Potential of customer
connections All input signals (control) must be supplied with the same potential.
All output signals (status signals) must be supplied with the same potential.

Safety standards All externally connected devices shall comply with the relevant safety standards.
Cable installation in ac-
cordance with EMC Signal and bus 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 and bus 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 long parallel paths with cables being either susceptible to interference or
interference sources.
●For the connection of remote position transmitters, screened cables must be
used.
