Transducer Block Parameters Description
Bit 04 User Output R3 (optional) – Indicates the field unit AS-3 Relay
has been energized. This relay is configurable to operate under many
conditions including FF control. Verify current configuration using the
LCS. This is a latched digital output, referenced as terminal points 31
and 32.
Bit 05 User Output R4 (optional) – Indicates the field unit AS-4 Relay
has been energized. This relay is configurable to operate under many
conditions including FF control. Verify current configuration using the
LCS. This is a latched digital output, referenced as terminal points 42
and 43.
Bit 06 User Output R5 (optional) – Optional I/O board required.
Indicates the optional field unit AR-1 Relay has been energized. This
relay is configurable to operate under many conditions including FF
control. Verify current configuration using the LCS. This is a non-
latching digital output, referenced as terminal points 35 and 36.
Bit 07 User Output R6 (optional) – Optional I/O board required.
Indicates the optional field unit AR-2 Relay has been energized. This
relay is configurable to operate under many conditions including FF
control. Verify current configuration using the LCS. This is a non-
latching digital output, referenced as terminal points 44 and 34.
Bit 08 User Output R7 (optional) – Optional I/O board required.
Indicates the optional field unit AR-3 Relay has been energized. This
relay is configurable to operate under many conditions including FF
control. Verify current configuration using the LCS. This is a non-
latching digital output, referenced as terminal points 33 and 20.
Bit 09 Network Bypass Relay – Indicates the network bypass relay is
energized. Should this relay be de-energized, the actuator will fail to
communicate with the host. Value of 1=True, Value of 0=False.
Bit 10 R8
Bit 11 Not Used
Bits 12-15 MOV Series (MX=1, MXa=9, QX=6, QXm=B)
Subparameter 4 uint16_var Digital Input_1 – Read only 16-bit unsigned value. Contains field unit
status and digital input status.
Bit 00 Remote Selected – Monitors the actual LCS. Indicates the LCS
has been switched to the Remote position. The host is in control of the
actuator. Value of 1=True, Value of 0=False.
Bit 01 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 02 Open Torque Switch – Indicates an overtorque condition while
traveling in the open direction. This condition will also be true if the
actuator is 100% open and torque seated. Value of 1=True, Value of
0=False.
Bit 03 Open Limit Switch – Open limit switch is engaged. Valve is fully
opened. Value of 1=True, Value of 0=False.
Bit 04 Close Torque Switch – Indicates an overtorque condition while
traveling in the close direction. This condition will also be true if the
actuator is 0% open and torque seated. Value of 1=True, Value of
0=False.
Bit 05 Close Limit Switch – Close limit switch is engaged. Valve is fully
closed. Value of 1=True, Value of 0=False.
Bit 06 Not Used
