the meaning of every diagnosis event listed in
the extended diagnostic block is documented
in the GsD file where to each bit corresponds
a specific text to describe the device related
diagnosis.
a full Profibus DP compliant master should
be able to show the correspondent text in the
event of a diagnostic message.
• Not Operative in Open direction
this bit is set when the open commands are
not available due to current alarm trip in open
direction.
the diagnostic indication is cleared when
the alarm that has generated the fault
disappears.
• Not Operative in Close direction
this bit is set when the close commands
are not available due to current alarm trip in
close direction.
the diagnostic indication is cleared when
the alarm that has generated the fault
disappears.
• Power Failure Alarm
this bit is set when the main supply is not in
the proper range.
the diagnostic indication is cleared at
the next power up if the power supply is
corrected.
• HI-HI Torque in Opening
this bit is set when the torque has reached
the programmed limit while the actuator was
moving in opening direction.
the diagnostic indication is cleared by a close
command.
• HI-HI Torque in Closing
this bit is set when the torque has reached
the programmed limit while the actuator was

moving in closing direction.
the diagnostic indication is cleared by an
open command.
• Stroke Limit Alarm
this bit is set when the current position is
behind the open or close limit switches or as
result of an incorrect torque set..
the diagnostic indication is cleared when the
position returns within the limits or after a
successful torque configuration procedure.
• Alarm on Optional Local Control
(pushbutton)
this bit is set when the optional local control
does not work correctly.
the diagnostic indication is cleared when the
local control works without problems.
• Motor Direction Alarm
this bit is set when the motor drive has
recognized an incorrect behaviour.
the diagnostic indication is cleared by a
command in the opposite direction.
• Jammed Valve
this bit is set when the actuator detects a
jammed valve condition.
the diagnostic indication is cleared by a
command in the opposite direction.
• Hardware Error
this bit is set when the actuator detects a
general hardware error.
the diagnostic indication is cleared at the
next power up under normal condition.
• Position Sensor Failure
this bit is set when the actuator detects that
executing a command the position sensor is
not working properly.
the diagnostic indication is cleared by a
command in the opposite direction.
• HI-HI Temperature
this bit is set when the internal temperature
is out from the operational limits.
the diagnostic indication is cleared when the
internal is within the limits.
• Local Configuration in Progress
this bit is set when the actuator detects
that a local operator is executing a local
configuration.
the diagnostic indication is cleared when the
local operator finishes the configuration and
the actuator returns to normal operations.
