Actuator Options
The actuator may or may not contain any one or all of the following options:
•
•
•
•

Alarms and Status
There are no dedicated channels for Status and Read back; however, alarms can be monitored
from the DD. The following table depicts the applicability of each Field Device Alarm, with
respect to Actuators. These Alarms are mapped to Command #48 Response Bytes.

Phase Monitor – Phase monitors are not required for actuators with single-phase
motors and may not be installed in some actuators with three-phase power. If this
option is not installed, then the "Phase Monitor Alarm" of the "Actuator Status" will be
inactive. As such, the Phase Monitor alarm will always be "Zero" or "Off".
Analog Torque Transducer – If this option is not installed in the actuator, the "Torque"
analog channel is not available. The "Open Torque Alarm" and "Close Torque Alarm"
are always active from the torque limit switches.
Analog Auxiliary Output 1 – If this option is not installed, then "Analog Auxiliary Output
1" is not available. The actuator must have the optional 320B-2 module installed to
make this option available.
Torque Parameter - If the optional transducer is installed, it will provide the
instantaneous torque being generated by the actuator to the valve stem. The torque
value is expressed as a percentage of full scale of the rated torque of the actuator from
– 0% (normally closing) to 100% (normally opening). For TEC2, Model 500 and EHO
electric actuators, torque is a standard feature. For M2CP, it is optional and must be
specified when placing an order. For HQ actuator, torque options are not available.
