Indication
description
data type
range
e.u.
fully open
the fully Open indication is set to 1 when the actuator is at fully Open position. this indication
reflects the status of the open limit on the actuator.
Boolean
0-1
-
Opening
the Opening indication is set to 1 when the actuator is moving toward opening direction.
Boolean
0-1
-
closing
the closing indication is set to 1 when the actuator is moving toward closing direction.
Boolean
0-1
-
actuator moving
this indication is set to 1 when the actuator is moving either in opening or in closing direction.
Boolean
0-1
-
fully close
the fully close indication is set to 1 when the actuator is at fully close position. this indication
reflects the status of the close limit on the actuator.
Boolean
0-1
-
Motor stopped
this indication is set to 1 when the actuator is not moving and the motor has stopped.
Boolean
0-1
-
Intermediate
position
this indication is set to 1 when the valve is at an intermediate position.
Boolean
0-1
-
Positioner active
this indication is set to 1 when the on-board positioner is enabled.
Boolean
0-1
-
alarm in open
direction
Open command not available due to current alarm trip in open direction. the diagnostic indication is
cleared when the alarm that has generated the fault disappears.
Boolean
0-1
-
alarm in close
direction
close command not available due to current alarm trip in close direction. the diagnostic indication is
cleared when the alarm that has generated the fault disappears.
Boolean
0-1
-
general alarm
Bus can only read data due to alarm present. the diagnostic indication is cleared when all the alarm
conditions are cleared.
Boolean
0-1
-
LOcaL selected
No operation from bus because LOcaL selector switch is activated. the diagnostic indication is
cleared when the selector is turned to rEMOtE.
Boolean
0-1
-
HardWired mode
selected
No operation from bus because HarDWIrED mode is activated. the diagnostic indication is cleared
when the input HW MODE is not powered.
Boolean
0-1
-
PDa active
No operation from bus because PDa operator interface has the control (only if Bluetooth option is
available). the diagnostic indication is cleared when the PDa control is released.
Boolean
0-1
-
Monitor relay
this indication is set to 1 when the actuator is available for bus control. Monitor relay indication
means that the local selector is at remote position, no other remote interfaces have the control
(Hardwired or PDa) and no alarms are present.
Boolean
0-1
-
Power failure
alarm
this bit is set when the main power supply is not in the proper range. the diagnostic indication is
cleared at the next power up if the power supply is corrected.
Boolean
0-1
-
torque alarm 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
Boolean
0-1
-
torque alarm 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.
Boolean
0-1
-
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 Set procedure
Boolean
0-1
-
Local control alarm this bit is set when the optional Local control Module does not work correctly. the diagnostic
indication is cleared when the Local control works without problems.
Boolean
0-1
-
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.
Boolean
0-1
-
Jammed valve
this bit is set when the actuator detects a jammed valve condition. the diagnostic indication is
cleared by any new command.
Boolean
0-1
-
HW alarm
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.
Boolean
0-1
-
Position sensor
alarm
this bit is set when the actuator detects that position sensor is not working properly.
Boolean
0-1
-
High temperature
alarm
this bit is set when the internal temperature is out of the operational limits. the diagnostic indication
is cleared when the internal is within the limits.
Boolean
0-1
-
current position
the current position read from base card
Integer
0-1000
0.1%
current torque
the current torque read from base card
Integer
0-100
%
Internal
temperature
the current internal temperature
Integer
-45 +85
°c
