AUMA SA Series - Decommissioning; Lifetime; Operation

Risk of immediate actuator start when switching on if the motor/handwheel
locking device was removed while the motor was in disengaged position!
Risk of personal injuries or damage to the valve
→
Ensure that high level is present at the Safe ESDa/ESDb inputs when
switching on (standard: +24 V DC).
If the actuator is operated over a longer period (for several hours) while the
motor is disengaged, this entails considerable wear of the actuator.Worst
case would be accidental start-up or even destruction of the actuator.
On delivery, the motor is disengaged to prevent accidental start-up of the actuator
as well as consequential personal injuries or damage to the valve.
If the actuator is connected to 3-phase AC current without high level is present at
the Safe ESDa/ESDb inputs (default: +24 V DC), the motor will start without any
movement at the output drive.
→
Operational actions have to be provided ensuring that the described state only
persists for a short time, i.e. a few minutes at the maximum.
→
Remove the motor locking device prior to commissioning. It must only be used
for a short time during proof test.
After commissioning, the safe actuator function must be verified. Refer to <Proof
test> chapter.
5.3. Operation
Regular maintenance and device checks in determined T
proof
intervals are the basis
for safe operation. The figures indicated in the <Safety figures> chapter are valid for
T
proof
= 1 year.
For operation, both the pertaining operation instructions and the Manual (Operation
and setting) AUMATIC AC 01.2 have to be observed.
In case of possible failures or defects of the safety system, safe function must be
guaranteed by introducing alternative actions. Furthermore, a detected fault including
fault description has to be sent to AUMA Riester GmbH & Co. KG. Autonomous
repair work by the plant operator is not permitted.
5.4. Lifetime
Lifetime of actuators is described in the technical data sheets or the operation
instructions.
Safety-related figures are valid for the cycles or modulating steps defined in the
technical data specifications for typical periods of up to 10 years (the criterion
achieved first is valid). After this period, the probability of failure increases.
5.5. Decommissioning
When decommissioning an actuator with safety functions, the following must be
observed:
●
Impact of decommissioning on relevant devices, equipment or other work must
be evaluated.
●
Safety and warning instructions contained in the actuator operation instructions
must be met.
●
Decommissioning must be carried out exclusively by suitably qualified personnel.
●
Decommissioning must be recorded in compliance with regular requirements.
