Definition in compliance with EN ISO 5211:
A part-turn actuator is an actuator which transmits a torque to the valve for less than
one full revolution. It need not be capable of withstanding thrust.
AUMA part-turn actuators are driven by an electric motor. A handwheel is provided
for manual operation. Switching off in end positions may be either by limit or torque
seating. Controls are required to operate or process the actuator signals.
The AUMATIC actuator controls 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.
Operation, setting, and display can be performed on site directly at the controls

Protection on site
The pertaining wiring diagram/terminal plan (in German and English language) is
attached to the device in a weather-proof bag, together with these operation
instructions. It can also be obtained from A UMA (state commission no ., refer to name
plate) or downloaded directly from the Internet (www.auma.com).
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
the motor (refer to electrical data sheet) plus the current consumption of the controls.

If the controls (electronics) are supplied externally with 24 V DC and DC motors (24
V DC, 48 V DC, 60 V DC, 110 V DC, 220 V DC) are used simultaneously, the 24 V
DC voltage supply for the controls should be ensured via the XK25/26 terminals,
separately from the power supply (U1, V1). In case of common supply using a single
cable (links from U1, V1 with XK25/26, for 24 V DC only !!!), short-term excess or
falling below the permissible voltage limits can be the consequence during s witching
(24 V DC +10 %/–10 %). Any possibly incoming operation commands are not
executed outside the admissible limit values.The controls briefly signal a fault
condition.
All input signals (control) must be supplied with the same potential.
All output signals (status signals) must be supplied with the same potential.
All externally connected devices shall comply with the relevant safety standards.
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

●
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 par allel paths with cab les being either susceptible to interf erence or
interference sources.
●
For the connection of remote position transmitters, screened cables must be
used.

The wall bracket allows separate mounting of controls and actuator.
●
Application
Design
Observe prior to
connection
If the actuator cannot be accessed.
●
If the actuator is subject to high temperatures.
●
In case of heavy vibration of the valve.
●
Permissible length of connecting cables: max. 100 m.
●

SGExC 05.1 – SGExC 12.1 Control unit: electronic (MWG)
ACExC 01.1 Non-Intrusive Electrical connection
●
If the AUMA cable set is not used:
- Use suitable flexible and screened connecting cables.
- Use separate CAN bus cable of 120 Ohm character impedance for MWG
(e.g. UNITRONIC BUS-FD P CAN UL/CSA - 2 x 2 x 0.5 mm², manuf acturer:
Lapp).
- Data cable connection: XM2-XA2 = CAN L, XM3-XA3 = CAN H.
- MWG voltage supply if the A UMATIC has been ordered and delivered with
wall bracket: XM6-XA6 = GND, XM7-XA7 = + 24 V DC (refer to wiring
diagram).
- MWG voltage supply if A UMATIC has been subsequently separated from
the actuator: XM6-XA6 = GND, XM11-XA117 = + 5 V DC (refer to wiring
diagram).
●
When using connecting cables, e.g. of the heater, requiring direct wiring from
the actuator to the XK customer plug (XA-XM-XK, refer to wiring diagram),
these connecting cables must be subject to an insulation test in compliance
with EN 50178. Connecting cables for MWG do not belong to this group.They
may not be subject to an insulation test.
5.4.2 Parking frame Application
Parking frame for safe storage of a disconnected plug.
For protection against touching the bare contacts and against environmental
influences.
