Metso Valvcon ADC Series User Manual

16. GENERAL OPERATING INFORMATION
For enclosure specifications and dimensions, see (Tables
1-2 and Figure 26).
16.1 Enclosure Ratings and Product
Certifications Metso offers two versions of ADC-Series actuator
enclosures: the “W” enclosure is weathertight, and the “WX”
enclosure which is weathertight and explosion-proof.
16.2 Operating Temperature Limits
ADC-Series actuators are designed to operate in ambient
environments between -40˚F (-40˚C) and 130˚F (55˚C). In
outdoor applications where ambient temperatures exceed
80˚F, actuators should be shielded from direct sunlight.
In applications with high media temperatures, insulating
blankets, heat shields and/or extended mounting shafts
should be used to maintain ambient temperatures at the
actuator within normal operating limits.
Activation of the heater and thermostat option is
recommended for all outdoor applications and may also be
used to dry condensation in high humidity environments.
16.3 Actuator Mounting
The actuator may be mounted in any position including
upside-down. It must be firmly secured to a direct mount
flange or sturdy mounting bracket. A minimum of four
bolts with lock washers should be used to secure the
actuator to the bracket. Flexibility in the bracket is not
allowed, and backlash, or “play”, in the coupling should
be minimized. The actuator output shaft must be in line
(centered) with the valve shaft to avoid side-loading the
shaft. See (Figure 26) for output drive dimensions and
mounting hardware specifications.
WARNING
FAILURE TO USE MANUAL OVERRIDE PROPERLY COULD RESULT
IN DAMAGE TO THE ACTUATOR GEARING. ENSURE THAT THE
OVERRIDE IS FULLY DISENGAGED AND DO NOT USE EXCESSIVE
FORCE WHEN MANUALLY POSITIONING ACTUATOR. DO NOT DRIVE
THE ACTUATOR BEYOND THE TRAVEL LIMIT SETTINGS. FAILURE TO
FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE
ACTUATOR AND/OR FINAL DRIVE ELEMENT.
16.4 Manual Override
To use the manual override, push the override shaft down
approximately 1/4 inch to disengage the motor from the
gear train. Failure to disengage motor prior to turning
override will cause damage to the actuator. While holding
the shaft down, turn the shaft with a wrench or handle to
the desired position.
NOTE: The override shaft on actuators below 1000 lb•in must
be rotated in the opposite direction of the desired direction
of the output shaft. In actuators 1000 lb•in and above, the
override and the output shaft turn in the same direction.
Do not drive the actuator beyond the limit switch settings;
it is possible to damage installed options such as a feedback
potentiometer. The manual override shaft must be returned
to its fully upward position before the motor is re-engaged.
Rotate the shaft slightly to align the spur gears until the
shaft “springs” back to its re-engaged position.
NOTE: The rotation direction of the output may not be the
same as the rotation of the override shaft!
16.5 Lubrication
All rotating power train components are permanently
lubricated with multi-purpose Lithium grease suitable for
the operating temperature range of the actuator. Additional
lubrication is not required in normal operation.
16.6 Problem Prevention
Most actuator problems result from improper installation.
• Incorrect Wiring and Set Up Make certain the actuator
is wired correctly and travel stops are properly set
before power is applied.
• Coupling, Alignment, and Mounting Do not add extra
torque! Make certain that the mounting arrangement
is sturdy, centered, properly aligned, and that all
mounting hardware is secure and properly tightened.
• Moisture Replace the cover tightly and make certain
conduit entry holes are sealed properly to prevent
moisture infiltration.
16.7 Warranty
All V-Series actuators are backed by a 2 year warranty that
covers materials and workmanship. The warranty shall
expire 24 months from installation or 30 months from
delivery; whichever comes first.
To request a Return Authorization for an actuator within the
warranty period, please consult your local Metso distributor.
16.8 Repair Service/Spare Parts
We recommend that electric actuators be directed to our
Northeast Service Center for maintenance. The Service
Center is equipped to provide rapid turn-around at
reasonable cost and offer new product warranty with all
reconditioned electric actuators.
For electric actuators outside of the warranty period,
request a Return Authorization by calling the Northeast
Service Center at (508) 595-5195; or by sending an e-mail to
valvconservice@metso.com.
NOTE: When sending electric actuators to the Service
Center for repair, do not disassemble them! The actuator
should be relatively clean upon return. For further informa-
tion on spare parts and service or assistance, visit our Web
site at www.metso.com/electricactuators.
NOTE: When ordering spare parts, always include the
following information:
a. Actuator model number from the product nameplate
b. Serial number from the product nameplate
c. Part number and/or description
