2. Application and validity
2.1. Range of application
AUMA actuators and actuator controls with the safety functions mentioned in this
manual are intended for operation of industrial valves and are suitable for use in
safety instrumented systems in accordance with IEC 61508 or IEC 61511.
The fail safe unit is part of the actuator and capable to operate the connected valve
once into a previously defined safety position and remain in this position without
external energy supply.
Hardware, software and configuration of the fail safe unit and the pertaining actuator
may not be modified without prior written consent by AUMA. Unauthorised
modifications may have a negative impact on both safety figures and SIL capability
of the fail safe unit.
The user may only deploy the fail safe unit within safety instrumented systems once
the following is ensured:
●
The fail safe unit may only be operated in low demand mode.
●
All materials, environmental and process conditions must be compatible with
the manufacturer data and the restrictions by AUMA (refer to technical data
sheet and operation instructions in particular).
●
All activities specified in this safety manual must be performed and defined re-
strictions be heeded.
●
All application restrictions indicated in the operation instructions, the technical
data and the order-related Declaration of Incorporation must be heeded.
When deploying the fail safe unit within a SIS, IEC 61508, IEC 61511 or the applicable
product standard must be heeded.
Materials, environmental conditions and process conditions must be compatible with
the manufacturer’s indications and AUMA’s restrictions.
All activities specified in this safety manual must be performed and defined restrictions
be heeded.
2.2. Standards
The safety-related part of the fail safe unit was developed and evaluated in compliance
with IEC 61508 Ed. 02. Safety figures were calculated and an FMEDA was executed.
2.3. Valid device types
The data on functional safety contained in this manual applies to the device types
indicated.

Approved versions and configurations of the safety-relevant part of the fail safe unit
are described in AV 06.03.027xx “Working specifications for FQM in SIL version”.
This safety manual refers to two internal wiring variants of the end position switches.
You can identify the variant from position 6 of the wiring diagram number of the FQM:
Variant 1 = Position 6 of the wiring diagram number is “C” (e.g. TPA34***C********)
Variant 2 = Position 6 of the wiring diagram number is “C” (e.g.TPA34***D********)
