The actuator has been congured as specied in the order. No further changes should be necessary other
than setting the position limits, and, if network controlled, setting a unique network address. If full data
was not provided when ordering or if changes are needed, see the TEC2 Installation & Operation Manual
(E2K-405-0614), which can be found at www.emerson.com/bettis. Verify the voltage rating on the unit
nameplate. Connect power to the unit.
Are Position Limits Set?
Does “SET LIMITS BEFORE OPERATING,” “EE%,” and the alarm icon appear, and is the yellow LED
