HRCL and HRCD advanced stand-alone actuators are designed to be installed in new contruction sites or existing
sites where there are NO existing local control capabilities. These single phase and low voltage proportional control
actuators have several versions that continue to add more features and options than the standard actuator range.
These units accept analog control signals (4-20mA or 2-10vdc) and process these incoming signals to position the
actuator as a function of the incoming signal. Additionally, these units generate an analog feedback signal proportional
to the position of the actuator and not directly related to the incoming signal. This feedback signal is designed to be
used by automation devices or displays external to the actuator.
Moreover, these units incorporate a Local Control Station (LCS) to facilitate operating the actuator locally. Having this
feature allows operation of the actuator WITHOUT having an existing PLC or BAS based analog controller while also
providing operability with existing external controls.
Inside the actuator/LCS package, you will
find:
1 . Integral
Local Control Device
. This
series is designed to operate in Local
mode (control knobs located on the face
of the LCS which is an integral part of
the actuator) or in Remote mode, which
utilizes commands from a PLC, BAS
or other volt-free contact (dry contact)
automation device.
A. While in Local mode, the actuator
responds to the position of the
controls located on the face of the
integral LCS.
B. The Mode switch employs a
padlockable lever that locks the
Mode switch in any of its three
positions, preventing unauthorized
changes in the operating mode
(Local, Off or Remote).
2 . Proportional Controller
. When the unit is
in Remote Mode, this analog processing
Printed Circuit Board (PCB) accepts
4-20mA or 2-10vdc from the field and
positions the actuator accordingly, utilizing
the internal reversing motor starter. A
4-20mA or 2-10vdc feedback signal is
internally generated to provide remote
reading of the position of the actuator.
