Modulating duty
The load is measured by means of the switching frequency, e.g. the number of
starts/hour at a defined torque, the AUMA load profile.
One start corresponds to a movement of 0.25 turns in both directions.
AUMA load profile:
35 % of maximum actuator torque.
Determination
Key figures
Operating cycles and number of starts for PROFOX actuators can be determined
using the AUMA CDT software.
Operating cycles
The number of operating cycles can be further determined using the AUMA CDT
software and the AUMA Cloud. For this, create an actuator snapshot and upload it
to the AUMA Cloud. The AUMA Cloud menu “My devices” indicates the value for
“Number of Full Stroke Equivalent” for the actuator.
Number of starts
The number of starts in indicated in starts/h. The exact sum of this key figure is made
in the actuator and can be read via AUMA Assistant App or the AUMA CDT software
in “Operational info”.
AUMA recommendation
We recommend contacting the AUMA Service for an inspection of the actuator if one
of the following conditions is reached:
●
The actuator life is more than 12 years
●
The maximum number of operating cycles has been reached at a lower load
profile than specified by AUMA (for open-close duty).
●
The maximum number of starts has been reached at a lower load profile than
specified by AUMA (for modulating duty).
An inspection by the AUMA Service can also be carried out using digital snapshots
from the AUMA Assistant App or the AUMA CDT software.
Mechanical position indicator
Both indicator glass and screw plug of mechanical position indicator are made of
plastic. To ensure enclosure protection and a long lifetime, both components must
be fastened at a defined torque:
Indicator glass cover: 6 Nm (special tool art. no. V004.027-02, available with AUMA)
Screw plug: 1.6 Nm
