Bit 13 Close Torque Switch Fault – Indicates an overtorque condition while traveling in the close direction. The
actuator will not move in the close direction again unless the actuator is first moved toward the open position. Torque
switch is not set when a normal torque out occurs at the torque limit. 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.
Register 10
Fault register. Read-only. 16-bit unsigned value. Contains additional field unit status. This register is optional for
controlling a field unit.
Bit 00 Open Inhibit Active – Indicates field unit has been issued an open inhibit command. Value of 1=True, Value of
0=False.
Bit 01 Close Inhibit Active – Indicates field unit has been issued a close inhibit command. Value of 1=True, Value of
0=False.
Bit 02 Not Used
Bit 03 Not Used
Bit 04 Phase(s) Missing Fault – 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.
Bit 06 ESD Conflict – ESD mismatch has occurred. Event with highest configured priority will be initiated. Value of
1=True, Value of 0=False.
Bit 07 Inhibit Conflict – Inhibit mismatch has occurred. Value of 1=True, Value of 0=False.
Bit 08 CSE in Local / Stop – Indicates remote control station is in Local or Stop. Input must be set for CSE and also
enabled. Value of 1=True, Value of 0=False.
Bit 09 Not Used
Bit 10 Network ESD is ON – Indicates field unit has been issued a network ESD command. The field unit will
command the actuator to operate to the preconfigured position (Open, Close, Stop, Ignore). The network ESD
command must be terminated to reset this bit. Value of 1=True, Value of 0=False.
Bit 11 Local ESD is ON – Indicates field unit has been issued a local ESD command. The field unit will command
the actuator to operate to the preconfigured position (Open, Close, Stop, Ignore). The local ESD command must be
terminated to reset this bit. Value of 1=True, Value of 0=False.
Bit 12 Unit Reset Since Last Poll – Indicates field unit has reset since the last network poll. This bit is latched until
read by the host controller. Value of 1=True, Value of 0=False.
Bit 13 MX in Stop Mode – Indicates the actuator LCS has been switched to the Stop position. Value of 1=True, Value
of 0=False.
Bit 14 Opening in Local Mode – Monitors the actuator LCS Open switch. Indicates the actuator LCS has been
switched to the Local position AND the actuator is being opened via the LCS. The host does not have control of the
actuator. Value of 1=True, Value of 0=False.
