ACTUATOR OPERATIONAL CONCEPTS

Notice: The HRSN2 Series is produced in two distinct versions: one with a manual override shaft on the bottom of the
actuator (HRSN2A & 2R), and the other with a manual hand wheel on the side of the actuator (HRSN2B & 2S).
Notice: ALL HRSN2 Series actuators rotate CW to CLOSE the output shaft (out the bottom of the actuator) when viewed
from ABOVE. On HRSN2A & 2R models, the cam shaft and the indicator rotate CW to close as well. However on
HRSN2B & 2S models, the cam shaft and the indicator rotate CCW (opposite the output shaft).
Notice: The calibration procedures are specific to each model. The HRSN2A & 2R use one common procedure, while the
HRSN2B & 2S use a second procedure common to those two models. Please be sure to follow the correct sequence for
your model.
Notice:
HRSN2 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.
