General functions are set as described in the Operation instructions or the Manual
(Operation and setting) AUMATIC AC 01.2.
Configuration of safety-related functions is listed in the order-related technical data
sheet.
The operating time for fail safe operation can be set – within certain limits:
●
In the factory, one of two configurations (10 % or 30 %) is selected for the point
from which the fail safe operation is decelerated when approaching the end
position (refer to wiring diagram: Switch 30%).This setting cannot be changed.
●
Bridges between connections XF 31-34 within the electrical connection can in-
fluence the speed of the fail safe operation in four stages:This setting can be
changed in the field (on site).
The <Typical fail safe operating times under standard conditions> shows the relation
between the typical fail safe operation time under standard conditions (see note
below) the configuration of the switch 30% specified in the factory, as well as the
configuration of XF 31-34 terminals.The minimum operating time under standard
conditions amounts to 50 % of the indicated values, the maximum operating time
under standard conditions amounts to 200 % of the indicated values.
Information
●
The indicated typical minimum and maximum fail safe operating times refer to
a swing angle of 90°.
●
The indicated typical minimum and maximum fail safe operating times refer to
the absolute end stop setting of the fail safe end position as set in the factory
and a load profile in accordance with EN 15714-2:2009 (standard conditions).
●
The indicated typical minimum and maximum fail safe operating times require
the ESD demand to remain present while the fail safe function is executed (fail
safe operation). Should the ESD demand be cancelled while executing the fail
safe operation, the actuator will nevertheless run to the fail safe end position.
The indicated operating times might, however, not be respected.
●
The typical operating time exclusively applies at normal temperature.
For different swing angles, absolute end stop settings in the fail safe end position
(even if the swing angle remains unchanged at 90°) and load profiles, the operating
time will change accordingly. In this case, the tolerance of the fail safe operating
time of –50 %/+100 % does not refer to the values indicated in the <Typical fail safe
operating times under standard conditions > table, but to the new typical fail safe
operating time generated by the modified configuration. A malfunction of the electric
actuator or the actuator controls can also have an impact on the fail safe operating
time (refer to page 11, Safety functions).
Information
If the operating time is changed in the field via XF 31-34 terminals, the following tests
and checks must at least be performed:
●
Proof test according to <Proof test> chapter.
●
Measurement of fail safe operating time during the proof test and/or real service
conditions.
●
Check whether the measured fail safe operating time meets the values indicated
in the <Typical fail safe operating times under standard conditions> table (while
observing the Information above) or the requirements of the application.
