Pagina afdrukkenIOM FOR DYNATORQUE™ SANDWICH DECLUTCHING MANUAL OVERRIDE (SD TYPE)
Safety:
The use of handwheels larger than recommended by the factory, cheater bars, etc. will void the override
warranty and may cause damage to the operator, valve stem, drive shafts, or other torque transmitting
devises as well as being dangerous to the user. Additionally, the use of chainwheels on operators that are
not recommended for those applications will result in voiding operator warranty.
Important Safety Note: For SD Override / Spring Return Actuator Combinations:
When using declutchable manual overrides in combination with spring return actuators, it is very
important not to attempt to disengage the manual override when the actuators spring is compressed.
Doing so will allow the spring to move the assembly to its failed position very quickly, potentially causing
damage to the assembly as well as possible injury to the human operator.
Operation:
In the event the pneumatic actuator's power supply fails, a double acting pneumatic actuator will remain
in its last position, and a spring return actuator will move to its failed position. Make sure that the
pneumatic actuator's cylinders have been vented to atmosphere.
To manually override the actuator:
1. Grasp the override engagement handle, squeezing the bottom handle and top handle together.
2. With the handles still squeezed together, rotate the handle from its declutched position
counterclockwise toward the pneumatic actuator mounting flange until the handle locking tabs are
in line with their locking positions.
a. In some cases the override gear teeth will not mesh correctly when rotating the handle
upward. If this occurs, rotate the override handwheel slightly to mesh the gears and then
rotate the declutch handle counterclockwise.
3. Once the override handle is in its locked position, the override is ready to be used.
4. Clockwise rotation of the override handwheel will produce clockwise rotation (as viewed from
above) of the override output, valve, etc.
5. Conversely, counterclockwise rotation of the handwheel will produce counterclockwise rotation of
the override output, valve, etc.
6. Note: When pneumatic actuator air has been restored, the manual override must be returned to
its declutched position. Reversing the procedure above will return the override to the declutched
position.
7. Assure the handle locking tabs are inserted into their locking position on the override housing.
8. Leaving the declutching handle engaged will prohibit the pneumatic actuator from cycling the
valve and may cause damage to the override as well as drivers' linkages, etc. and void the
override warranty.
Maintenance:
A. Storage: For best results, DYNATORQUE operators should be stored in a clean, dry area in their
original factory shipping containers. If operators are stored in high humidity areas, steps should
be taken to reduce the amount of moisture the units will be exposed to. Operator input shafts are
plated or stainless steel to prevent corrosion. If operators are being stored for a long period of
time, operator mounting surfaces should be lightly greased to prevent corrosion.
