Notice: HRCK, HRCP, HRCL & HRCD 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 nd that no adjustments
are needed. The assembly can be put into service immediately.
If, however, it should 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 in the Installation,
Operation and Maintenance Instructions (IOM) for each unit should be followed to put the assembly into
service. Note that there is a maximum adjustment range of +/- 3° at each end of travel.
CAUTION – For any 3 Phase products (i.e. HRCK4AR8), refer to the IOM for the respective 3 Phase unit.
These instructions are specic to low voltage and single phase products only.

THEORY OF OPERATION
HRCK and HRCP 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 actuators have
several versions that continue to add more features and options than the standard actuator range.
Moreover, these units incorporate a Local Control Station (LCS) to facilitate operating the actuator. 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 nd:
1. Integral Local Control Device. This series is designed to operate in Local mode (control knobs or buttons 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 Remote mode, the Remote
devices must have volt-free contacts
(dry contacts) which will switch the
actuator’s internal 24vac power
supply to generate commands to
drive CW or CCW.
B. While in Local mode, the actuator
responds to the position of the
controls located on the face of the
integral LCS.
C. The Mode switch (CK Series) is operated
by a removable key which, when
removed, will prevent unauthorized
changes in the operating mode
(Local, Off or Remote).
D. The Mode button (CP Series) is
protected by a lockable cover
plate which, when locked, will
prevent unauthorized changes in
the operating mode (Local, Off or
Remote).

Panel Indicators
This round NEMA 4X/IP65 enclosure houses two rotary control knobs that provide the user with
the ability to operate the actuator in a normal (REMOTE) mode where the actuator responds
to control signals from a building automation system or a PLC or other control device (by
others). Or the user can elect to operate the actuator in LOCAL mode where one can control
the positioning of the actuator while standing AT the device. This allows opening and closing
the actuator (valve) to test for operation, perform maintenance or other function without relying
on radio communication to command the automation system to position the actuator.
A Key is provided for lockout and secured access to the MODE control switch of the
actuator. With the key removed (from any of the three positions), the MODE switch cannot
be changed.
The Position Indicators (top).
POWER (POWER indicator, all actuators): The Power LED is illuminated whenever power is
present at the unit, regardless of MODE position.
The panel also contains two colored LED indicators to provide visual indication of the position
and status of the actuator. The green Fully Open LED corresponds to the OPEN actuator
position. The red Fully Closed LED corresponds to the CLOSED actuator position. Both remain
steady ON when their respective end of travel is reached.
The MODE switch (right hand side) has three positions.
• REM (REMOTE, On/Off actuators): sets the actuator to respond to eld generated
control signals. In this mode the POSITION KNOB has NO affect on the positioning
of the actuator. All actuator movement is controlled by the external signal device.
The manual handwheel may be used to reposition the actuator while in this mode;
however, if an active external signal is present, the actuator WILL reposition as a
function of that control signal. The indicators are active in this mode.
• REM (REMOTE, Proportional Control actuators): The actuator follows the incoming
4-20mA(2-10vdc) control signal, and generates a 4-20mA(2-10vdc) feedback signal
OUT which corresponds to the position of the actuator.
• LOC (LOCAL, On/Off actuators): sets the actuator to respond to the POSITION KNOB.
The indicators are active in this mode.
• LOC (LOCAL, Proportional Control actuators): The actuator responds to the function
of the POSITION knob AND generates a 4-20mA(2-10vdc) feedback signal OUT
which corresponds to the position of the actuator.
• OFF (all models) In the OFF position, electronic movement of the actuator is disabled.
The actuator will NOT respond to any incoming remote or local signals. The actuator MAY
be operated manually using the handwheel and the unit will STAY in its desired position.

ROUND LCS, PUSHBUTTON
Operating the
Local Control Station
This round NEMA 4X/IP67 enclosure houses four pushbutton control switches that provide the
user with the ability to operate the actuator in a normal (REMOTE) mode where the actuator
responds to control signals from a building automation system or a PLC or other control device
(by others). Or the user can elect to operate the actuator in LOCAL mode where one can
control the positioning of the actuator while standing AT the device. This allows opening and
closing the actuator (valve) to test for operation, perform maintenance or other function without
relying on radio communication to command the automation system to position the actuator.
The panel houses three status LED’s that indicate Power, Remote operation, and a Fault
indicator. There are also four push button switches (non-latching, push/push) two of which
also have ring surround LEDs providing the operational status of the actuator. Whenever power
is present at the unit, regardless of MODE position, the Power LED is illuminated.
REMOTE (REMOTE MODE indicator, all actuators):
• The RE/LO mode switches from Local to Remote and back with each
successive press of the push button (see below).
• When the unit is in Remote mode, the Blue Remote LED will be illuminated.
• When the unit is in Local mode, the Remote LED will be OFF.
POWER (POWER indicator, all actuators): The Power LED is illuminated whenever power is
present at the unit, regardless of MODE position.
FAULT (FAULT indicator, all actuators): The Fault LED is illuminated whenever there is a fault
detected in the actuator.
OPEN/CLOSE (OPEN and CLOSE indicators, all actuators): Regardless of the Mode of
operation (other than powered OFF), the Open and Close push buttons have internal LED
rings which ash Red (Closing) or Green (Opening). When end of travel is reached, the LED
indicators remain constant ON.
Panel shown with NO POWER
Panel shown in the
Remote Mode
Panel shown in the
Local Mode, actuator fully OPEN
RE/LO (REMOTE/LOCAL, all actuators): When the RE/LO push button is pressed, the mode
switches from Local to Remote and back with each successive press of the push button.
• REMOTE: When the unit is in Remote mode, the three Move push
buttons are disabled and have no effect on the operation of the actuator.
• LOCAL: When the unit is in Local mode (Blue LED OFF), the three Move
push buttons are enabled and one can control the position of the actuator
using the push buttons.
OPEN: Pressing the Open push button drives the actuator CCW until it reaches the end of
travel determined by the internal CCW travel cam settings.When pressed (momentary switch),
the unit will start and continue to drive until it reaches its full CCW position UNLESS the Stop
push button is pressed. This will arrest the CCW travel of the actuator and it will stay in its
current position UNLESS the manual handwheel is utilized.
CLOSE: Pressing the Close push button drives the actuator CW until it reaches its CW end of
travel limit switch.
STOP: Pressing the Stop push button stops the actuator in position.
Using the manual handwheel. In Remote mode with an active control signal present,
repositioning the actuator with the handwheel will result in the unit driving to maintain the
control signal command. i.e. if in Remote mode with a drive CW active control signal, if the
handwheel is utilized to reposition the actuator to mid-stroke, the motor will immediately drive
the actuator to its full CW position. While in Local Mode, the manual handwheel can be used
to reposition the actuator to any desired position AFTER the unit has reached its intended end
of travel position and the associated ring LED is illuminated.
This Control system employs a pad-lockable security plate that can be positioned over the
MODE push button and locked in place. This prevents changing the mode of operation. The lock
plate must be unlocked and swung out of the way to gain access to the mode switch function.

1-888-HAY-INDL (1-888-429-4635)
This rectangular NEMA 4X/IP67 (Optional IP68) enclosure houses two nonintrusive
(magnetic) rotary control knobs that provide the user with the ability to operate the
actuator in a normal (REMOTE) mode where the actuator responds to control signals
from a building automation system or a PLC or other control device (by others). Or
the user can elect to operate the actuator in LOCAL mode where one can control
the positioning of the actuator while standing AT the device. This allows opening
and closing the actuator (valve) to test for operation, perform maintenance or other
function without relying on radio communication to command the automation system
to position the actuator.
The panel houses a monochrome LCD screen that shows percentage of full OPEN
position as a default. There are individual LED’s to show Remote, Local, F.O. (Fully
Open) and F.C. (Fully Closed) operational status.
The MODE switch (right hand side) has three positions.
• STOP (STOP, On/Off actuators): STOP (center position) removes any ability
to reposition the actuatorelectrically. Power is still present in the unit, and
the OPEN and CLOSE LED indicators are operational. If the unit is fully
CLOSED (CW), then the REDLED will be steady ON. Due to its epicyclic
gear train, the manual handwheelCAN be used to position the actuator. The
actuator will remain in position lastdetermined by the use of the handwheel.
• STOP (STOP, Proportional Control actuators): The actuator generates
a4-20mA(2-10vdc) feedback signal OUT which corresponds to the position
of theactuator.
• REM (REMOTE, On/Off actuators): Sets the actuator to respond to eld
generated control signals. In this mode the POSITION KNOB (left side)
has NO affect on the positioning of the actuator. All actuator movement
is controlled by the external signal device.The manual handwheel may be
used to reposition the actuator while in this mode; however, if an active
external signal is present, the actuator WILLreposition as a function of that
control signal. The LED indicators are activein this mode.
• REM (REMOTE, Proportional Control actuators): The actuator follows
theincoming 4-20mA(2-10vdc) control signal, and generates a 4-20mA(2-10vdc)
feedback signal OUT which corresponds to the position of the actuator.
• LOC (LOCAL, On/Off actuators): Sets the actuator to respond to the
POSITION KNOB (see below).
• The LED indicators are active in this mode.
• All external eld signals are ignored and have no affect on the
positioning of theactuator.
• LOC (LOCAL, Proportional Control actuators): The actuator responds tothe
function of the POSITION knob (see below) AND generates a 4-20mA(210vdc)feedback signal OUT which corresponds to the position of the actuator.
The POSITION switch (left hand side) has three positions.
When in the LOC mode, the actuator has been set to respond to the POSITION
KNOB (left side).
• OPE (OPEN, all models): When the POSITION knob is set to OPE, the
actuator will drive to the full CCWposition.
• CLO (CLOSE, all models): When the POSITION knob is set to CLO, the
actuator will drive tothe full CW position.
• There is an unmarked HOLD position detente in theknob (see red dot at
left) that allows the actuator to maintain position at somepoint away from
full travel endstops. In this mode, the manual handwheelmay be used to
reposition the actuator and it will remain in position whilePOSITION knob
is in HOLD. The LED indicators are active in this mode. Allexternal eld
signals are ignored and have no affect on the positioning of theactuator.
