Transducer Block Parameters Description
Bit 04 Closing – Valve is traveling in the Close direction. This bit is ORd
with bits 00, 01, 02, 03. Value of 1=True, Value of 0=False.
Bit 05 Valve Jammed – Valve is jammed. The valve was traveling
or attempting to travel in either the Open or Close direction and has
tripped the torque switch. This bit is ONLY active if the actuator should
be commanded to move by the pushbutton station or remote control,
and an over-torque condition occurs. Value of 1=True, Value of 0=False.
Bit 06 NOT in Remote – Monitors the actuator LCS. Indicates the LCS
has been switched to the Local or Stop position. The host will not be
able to control the actuator. Value of 1=True, Value of 0=False.
Transducer Block Parameters Description
Bit 07 Combined Fault – The combined fault bit indicates there is a
severe problem with the field unit. When this bit is TRUE, the actuator
must be considered OFFLINE. This bit indicates a fault when both bits
(10 and 11) are TRUE or bit 5 or bit 8, or bit 9, or bit 15 is TRUE. Value
of 1=True, Value of 0=False.
Bit 08 Thermal Overload Fault – Indicates the motor has overheated
and the thermistor has opened. This unit is unable to operate and time
is required for the motor to cool and reset the thermistor. Value of
1=True, Value of 0=False.
Bit 09 Not Used
Bit 10 Not Used
Bit 11 Not Used
Bit 12 Open Torque Switch Fault – Indicates an over-torque condition
while traveling in the open direction. The actuator will not move in the
open direction unless the actuator is first moved towards the close
position. Value of 1=True, Value of 0=False.
Bit 13 Close Torque Switch Fault – Indicates an over-torque condition
while traveling in the close direction. The actuator will not move in the
close direction unless the actuator is first moved towards the open
position. Value of 1=True, Value of 0=False.
Bit 14 Valve Manually Moved – Indicates the valve position has been
changed by stroking the valve with the actuator handwheel. (Actuator
drive sleeve has rotated without motorized operation). Value of 1=True,
Value of 0=False.
Bit 15 Phase Error – Indicates loss of phase. Value of 1=True, Value of
0=False.
Subparameter 2 uint16_var Fault Register. Read only 16-bit unsigned value. Contains additional
field unit status. Optional for controlling a field unit.
Bit 00 Open inhibitactive
Bit 01 Closed inhibitactive
Bit 02 Not Used
Bit 03 Not Used
Bit 04 Phase Error – Indicates one or more phase(s) is absent for the
three-phase power. Value of 1=True, Value of 0=False.
Bit 05 Phase Reversed Fault – Indicates field unit has noticed incorrect
phase rotation of the incoming power. Value of 1=True, Value of
0=False.
