This rectangular NEMA 4X/IP67 (Optional IP68) enclosure houses two non-intrusive
(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 also contains ve bright LED’s to provide visual indication of the position
and status of the actuator. OPEN (green) and CLOSE (red) ash when the actuator
is MOVING open (CCW) or closed (CW), and they remain steady ON when end of
travel is reached.
The MODE switch (right hand side) has three positions.
• STOP (STOP, On/Off actuators): STOP (center position) removes any ability
to reposition the actuatorelectrically. 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 REDLED will be steady ON. Due to its epicyclic
gear train, the manual handwheelCAN be used to position the actuator. The
actuator will remain in position lastdetermined by the use of the handwheel.
• STOP (STOP, Proportional Control actuators): The actuator generates
a4-20mA(2-10vdc) feedback signal OUT which corresponds to the position
of theactuator.
• 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 WILLreposition as a function of that
control signal. The LED 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 (see below).
• The LED indicators are active in this mode.
• All external eld signals are ignored and have no affect on the
positioning of theactuator.
• LOC (LOCAL, Proportional Control actuators): The actuator responds to the
function of the POSITION knob (see below) AND generates a 4-20mA(2-
10vdc)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 CCWposition.
• CLO (CLOSE, all models): When the POSITION knob is set to CLO, the
actuator will drive tothe full CW position.
• There is an unmarked HOLD position detente in theknob (see red dot at
left) that allows the actuator to maintain position at somepoint away from
full travel endstops. In this mode, the manual handwheelmay be used to
reposition the actuator and it will remain in position whilePOSITION knob
is in HOLD. The LED indicators are active in this mode. Allexternal eld
signals are ignored and have no affect on the positioning of theactuator.
There is a padlockable lever that engages with the MODE
knob to lock the operation of the MODE switch in position.
It provides restricted access in any of the three positions.
