Page 4: Safety Considerations
EL Series actuators are not rated for operation in atmospheres containing acetylene. It is the responsibility of the user to provide for properly rated conduit connections to the EL Series actuator. Exlar takes no system responsibility beyond the actuator ratings. Curtiss-Wright | EL30 Rev. H PN23942 6/14/16... -
Page 5: System Configuration
Damage to equipment and injury to personnel can result. Many amplifiers have voltage present for a considerable time period after incoming power is removed. Take care to insure that the amplifier has discharged all power. Typical System Connections Curtiss-Wright | EL30 Rev. H PN23942 6/14/16... -
Page 6: Typical System Wiring
In some cases, if the proper current limits are not set in the amplifier, mis-wiring of the feedback cable can lead to damage of the motor. Curtiss-Wright | EL30 Rev. H PN23942 6/14/16... -
Page 7: Installation And Operation
Excessive side load on the output rod of the actuator will dramatically reduce the life of the actuator and should be avoided completely. Side load can be caused from misalignment or loading that is not in line with the actuator output rod. Curtiss-Wright | EL30 Rev. H PN23942 6/14/16... -
Page 8: Mounting Considerations
Care should be taken not to exceed the physical travel limits of EL Series Actuators. Doing so will cause the actuator to end- crash internally. End crashes can physically damage the roller screw and the internal components of the actuator. Curtiss-Wright | EL30 Rev. H PN23942 6/14/16... -
