HART© protocol and local pushbutton/LED panel and RS-232 serial commands
Demand Input Signal
Range
4–20 mA, 1–5 V dc
Minimum Step
0.1° of span
Hysteresis
0.25% of span at any point
Demand Input Signal
Characterization
Linear: Drive output shaft moves proportionally to the input signal.
Square: Drive output shaft moves proportionally to the square of the input signal.
Custom: 20 segment configurable curve fit
Position Feedback
Signal
4-20 mA
Isolation
Demand input and position Feedback signals are isolated from ground and the ac power line. Signal buffering provides 24 V dc isolation between the Demand and Feedback signals.
Action on Loss of
Power
Output shaft stays in last position
Action on Loss of Input Signal (Power on)
Stay in place or runs to any preset position (configurable)
Over-thrust Protection
If the output thrust of the drive exceeds 115% of the drive rating, the motor will shut off (feature can be enabled / disabled).
Stall Protection
If the motor tries to run in one direction for more than 300 seconds (configurable from 30 to 300 seconds), the motor will shut off.
Over-travel Protection Switches
Two Form C (Retract and Extend) provide over-travel protection
Auxiliary Switches
(Field Adjustable)
