Single phase actuators
range in complexity from simple models with basic operability, to quite complicated
models with battery backup and local control capabilities. The various models might seem to be easily adaptable
across any site or design intent, but are actually very specific a s to h ow they i nterface t o e xisting o r n ew
installations. It is important to FULLY UNDERSTAND what level of control is required prior to selecting one of
these products. While it might make sense to opt for the most feature-laden solution in order to cover all the
possibilities in a given application, that selection in fact would NOT function in an application that just required
the most basic unit.
Notice:
Read the project specifications and understand the application before making an actuator selection. If
in doubt, consult with the project engineer to clarify what is actually required for a fully operational installation.
We have provided in this document all the tools necessary to determine how the various levels interface to
the outside world. If there are any questions, please contact

.
Notice:
HRSN3 Series actuators are fully assembled, calibrated and tested prior to leaving our factory. In most cases, after
you have mounted the actuator to your device, you should be able to operate the actuator from fully CLOSED (CW) to fully
OPEN (CCW) and back again, and find that no adjustments are needed. The assembly can be put into service immediately.
However, should it be necessary to make adjustments to the end-of-travel positions to overcome any device related issues
(i.e. valve shaft incorrectly timed to the drive stem), the procedures outlined below should be followed to put the assembly
into service. Note that there is a maximum adjustment range of +/- 3° at each end of travel.
