TTX Series DC Actuator Installation & Maintenance Instructions
Curtiss-Wright | Rev D | PN75667 | 8/1/22
3.3 LUBRICATION
Tritex TTX linear actuators are shipped from the factory fully
greased and ready for installation. Exlar uses Mobil SHC 220,
a high performance, extreme-pressure grease. The unique
physical properties of the synthetic base oil provide outstanding
protection against wear, rust, corrosion, and high or low-
temperature degradation. See section 6.1 for more information
on lubrication.
3.4 OUTDOOR AND WASH DOWN INSTALLATIONS
CAUTION!
Liquid ingress damages Tritex TTX
electronics
Damage due to water or other liquids can be very extensive,
may not show up immediately, and is not generally covered
under warranty.
Tritex TTX ingress ratings: IP66S. Tritex TTX actuators are not
intended for applications where the actuator could possibly
be submerged. Liquid ingress causes serious damage to
electronics over time. A frequent and often overlooked entry
point is through conduit or wireways. When new, the seals are
effective to IP66S or better. However, over time, and depending
on the amount of side load, seals can wear and eventually allow
moisture in. Here are some additional recommendations to
prevent liquid entry:
1. Avoid installations with main rod or shaft facing up if
possible. Otherwise make external provisions to keep water
away from the main rod or shaft.
2. When using the power and I/O connectors verify the cable
end connectors can seal properly and have the desired
IP rating. Be sure to screw the plug all the way on to the
receptacle for proper sealing.
3. Position conduit fittings or
create a drip loop in cable or
flexible conduit so water does
not drain towards the conduit
fitting as shown.
4. When the wire termination
cover is re-installed, verify the
gasket is in place and the surfaces of the gasket as well
as the cover are free from debris so a good seal can be
achieved.
5. When re-installing the termination cover install all four
screws to within about one turn from contact, then hold the
cover flat in position and bring all screws to seat. Then
tighten the screws to about 0.8 Nm (7 lbf-in).
6. The Tritex TTX actuator has conduit hole plugs to cover
unused conduit entries, verify they are all in place and fully
seated.
