| GTX Series Actuator Installation & Maintenance Instructions
Curtiss-Wright | Rev D | PN75557 | 10/01/2019
3.3 LUBRICATION
GTX Series actuators are shipped from the factory fully greased
and ready for installation. Exlar uses Mobil SHC 220, a high-
performance grease that performs well under extreme pres-
sure. The unique physical properties of the synthetic-based oil
provide outstanding protection against wear, rust, corrosion and
high- or low-temperature degradation. Mobil SHC allows for
very low starting and running torque values. The Mobil SHC220
operating range is -40° C to 177° C (-40° F to 350° F).
4.0 ELECTRICAL INSTALLATION
4.1 SAFETY CONSIDERATIONS
DANGER!
NEVER attempt to connect or disconnect
an actuator with power applied. Dangerous voltages are
present with the potential to cause equipment damage and/
or personal injury or death. Many amplifiers have voltage
present for a considerable time period after incoming power
is removed. Use extreme caution to ensure all amplifiers
have discharged all power before proceeding.
WARNING!
Do NOT attempt to connect the power cable
to the motor feedback connector as this may cause damage to
the connector. Verify that pin patterns match before attempting
to connect cables to the actuator.
CAUTION!
GTX Series actuators can be operated
under a variety of conditions. General safety practices such as
lock-out and tag-out procedures should be followed during the
electrical installation of GTX Series actuators.
CAUTION!
Motor RMS current must be maintained at
a level below the continuous current rating of the GTX Series
actuator or damage to the motor stator will result. The peak
current setting must be maintained at a level below the peak
current rating of the GTX Series actuator or damage to the
stator will result.
4.2 CABLE ROUTING
To minimize the introduction of contaminants to the connector,
route the cables so there is a loop in the cable just prior to its
attachment to the connector (see Figure 8). Units mounted
with the connectors on the bottom surface of the actuator
require no looping.
IMPORTANT!
Follow cable manufacturers’ recommended
cabling bend radius.
