Thrust actuator ARI-PREMIO-Plus
9.1 Failure signals according to NAMUR NE 107
Warnings and information messages (blue, yellow or orange LEDs) do not interrupt the
control mode!
Actuator cannot be controlled
with analogue control signal
Actuator is set to 3-point
operation or is currently
controlled by a 3-point signal
(indicated by lit LED above 3-
point connector)
By withdrawing the connector for
the 3-point signal, you can
determine whether the actuator is
set to 3-point operation or
whether it is simply being
controlled by a 3-point signal
If the LED goes out, a 3-point
signal is present, e.g. from an
anti-freezing contact
If the LED is still lit, the actuator is
set to 3-point operation. An
analogue control signal must be
present during the initialisation
run in order to control the
actuator with an analogue signal!
Repeat the initialisation with an
analogue control signal applied
Actuator oscillates continuously
about a point
Xp setting on controller is too low
Increase the Xp value (refer to
