STORAGE
Actuators should be stored in a clean, dry environment at all times. Do not install
the actuator outdoors or in humid environments without immediately supplying
power to activate the internal heater. The thermostatically controlled heater will
help prevent possible damage caused by condensation build up inside the actua-
tor.
CONSTRUCTION AND EXPLOSION PROOF REGULATIONS
The casing construction of each anti-explosion component of the actuator can
withstand the explosive pressure generated by an interior explosion caused by an
explosive gas mixture, and prevent transmission and explosion to the external
explosive gas atmosphere.
*A detailed drawing of the explosion proof construction can be found in Figure 8.
MOUNTING
The actuator can be mounted in any orientation. Allow enough room around
actuator for manual operation as well as any maintenance. Valves can be direct
mounted to the actuator using standard ISO5211 international mounting pad.
TEMPERATURE RATING
Ambient temperature range of the actuator is –13 to +131ºF (-25 to +55ºC).
Heat from the working medium (fluid) should not allow actuator to exceed these
temperature limits.
ENCLOSURE RATING
The rugged aluminum housing is rated Type 4X and IP67 weatherproof.
VISUAL POSITION INDICATOR
Actuators are supplied with a local visual valve position indicator. This indicator is
yellow and located on top of the actuator. Indicator will show the open and
closed (on-off) position of the quarter-turn actuator (valve).
ANTI-CONDENSATION HEATER
The actuator has a standard integral thermostatically controlled 4 watt anti-
condensation heater. Power should be maintained either in the open or closed
position to activate internal heater. This heater will help prevent condensation
build-up inside the actuator.
DUTY CYCLE AND MOTOR PROTECTION
The rugged 5818 series actuators are rated 70% duty cycle. Actuators are
equipped with thermal overload protection with automatic reset to guard against
over torque situations.

POSITION CONFIRMATION SWITCHES AND MECHANICAL STOPS
Two auxiliary limit switches are provided to confirm the actuator (valve) open
and closed positions. (use of these switches is optional). In addition, rotation of
the output drive is limited by adjustable mechanical stops. These stops are
preset at the factory, no adjustment required.
MANUAL OVERRIDE
Valworx 5818 series electric actuators have a manual override for use during
setup or loss of electrical power. To operate the manual override, first
“REMOVE ALL ELECTRICAL POWER TO THE ACTUATOR” then open the
manual override protective cover located on the side of the actuator. Insert a
hex wrench (provided) and rotate to open (counter-clockwise) or close as re-
quired.
MAINTENANCE
There are no internal parts that require regular maintenance. The gear drive is
pre-lubricated for life. The housing may be cleaned with warm soapy water (no
solvents). The actuator should be cycled at least once per month.
DO NOT PRESSURE WASH.
OPERATION
Valworx 5818 series electric actuators with EPS- Electronic Positioning System
provide an accurate valve positioning function whereby the movement of the
actuator is controlled by a 4-20mA input control signal. Any change in the
control input signal results in a corresponding and proportional change in the
position of the actuator drive output.
This is achieved with a unique built in electronic positioning module. The mod-
ule is fully potted to help protect the electronics from vibration and moisture.
An internal microprocessor on the EPS circuit board continuously monitors the
analog input and output signals and compares them to the physical position via
a precision potentiometer feedback system, moving the drive output as required
to balance the signals.

ELECTRICAL WIRING
Confirm the actuator VOLTAGE is correct, then remove the terminal box cover and connect wiring to terminal strip according to appropri-
ate wiring diagram.
Wiring diagrams for each actuator are attached to the inside of the terminal box cover.
Input control signal type is 4-20mA. Actuator should have its own fused and isolated circuit. Do not connect actuators in parallel. Power
to actuator should be maintained to activate the internal heater. This heater will help prevent condensation build-up inside the actuator.

sponding and proportional change in the position of the actuator drive output.

Before connecting power, confirm correct VOLTAGE is
being applied. Incorrect voltage may damage actuator and
void the warranty.

these steps: Supply correct power to the actuator. Set switches to manual mode as shown below. Manually operate actuator using chart below. Once new desired
“Open” or “Closed” position is reached, hold down both the matching manual control button for the position you wish to set AND the White “SET” button simultane-
ously until the L2 red light comes on - then release both buttons. The position will now be set when you switch S-A back to original position.

2. Connect the leads per the appropriate wiring diagram.
Note: In order to meet explosion proof requirements, the connectors and hole
plugging materials need to meet the requirements of the CSA explosion proof
standards and be installed correctly.
3. Ensure the interior and exterior ground connections are properly made.
Note: the connection method in this manual is for explosion-proof pipe. The
user may choose other connection methods provided they meet all applicable
explosion-proof requirements.
