About the Book
This manual is to help you use the capabilities of the actuator safely and properly.
Follow the instructions within this manual to help:
oReduce risks
oReduce repair costs and downtime of the actuator
oIncrease the service life of the actuator
oIncrease the reliability of the actuator
This document has been updated for the release of EcoStruxureTM Machine Expert V1.2.
This manual is valid for the Lexium EAC1-Series.
The equipment described herein must be used in accordance with the application-specific risk analysis that you are to perform along with verification of all applicable standards. Pay attention in conforming to any safety information, different electrical requirements, and normative standards that would apply to your application of the information contained in the present manual and the manuals for associated equipment.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH |
|
oDisconnect all power from all equipment including connected devices prior to removing any covers, or installing or removing any accessories, hardware, cables, or wires. oPlace a "Do Not Turn On" or equivalent hazard label on all power switches and lock them in the non-energized position. oWait 15 minutes to allow the residual energy of the DC bus capacitors to discharge. oMeasure the voltage on the DC bus with a properly rated voltage sensing device and verify that the voltage is less than 42.4 Vdc. oDo not assume that the DC bus is voltage-free when the DC bus LED is off. oBlock the piston rod to prevent rotation of the drive system prior to performing any type of work on the drive system. oDo not create a short-circuit across the DC bus terminals or the DC bus capacitors. oReplace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper ground connection exists before applying power to the unit. oUse only the specified voltage when operating the actuator and any associated equipment. |
|
Failure to follow these instructions will result in death or serious injury. |
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
oPerform a hazard and risk analysis to determine the appropriate safety integrity level, and any other safety requirements, for your specific application based on all the applicable standards. oEnsure that the hazard and risk analysis is conducted and respected according to EN/ISO 12100 during the design of your machine. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
|
|
|
LOSS OF CONTROL |
|
oThe designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop and overtravel stop, power outage and restart. oSeparate or redundant control paths must be provided for critical control functions. oSystem control paths may include communication links. Consideration must be given to the implications of unanticipated transmission delays or failures of the link. oObserve all accident prevention regulations and local safety guidelines.1 oEach implementation of this equipment must be individually and thoroughly tested for proper operation before being placed into service. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
