NOTES:
> The local control station contains no terminal strips and all wiring is direct to the
switches and lights via 2 x ¾” NPT or holes in bottom of housing.
> Ordering the control station with optional pin connector receptacles will
eliminate the necessity of field wiring. Not all possible options are available with
receptacles. Consult factory.
> Control station will be completely factory wired and tested.
> Factory will need wiring diagram drawing number of the existing unit if it is to be
retrofit with a local control station. New wiring diagram will be provided based
upon this information.
> Local control station can be ordered with key lockable switches.
> Local control station requires a dedicated set of auxiliary switches. These
switches are required for turning on or off the lights on the control station to
locally indicate actuator position.
> Alternative mounting kit can be ordered in case it is preferred to mount the
control station nearby but not on the S70 actuator.
