Start-Up

Overview

When the Lexium™ MC12 multi carrier is operated for the first time, there is a risk of unintended equipment operation caused by possible wiring errors or unsuitable parameters.

You must take care that the carriers (depending on the shape of the product, size, mass, center of mass, acceleration, deceleration, velocity) keep enough distance from each other to help prevent collisions. Verify that you have implemented a device like, for example, a sensor for identifying the carrier and the type of tool mounted on the carrier to help prevent collisions. In addition, depending on the load and center of gravity, the speed of the carriers must be reduced on arc segments to help prevent the carriers from leaving the track.

Use the related libraries to program your application. The libraries provide function blocks and interfaces to control the Lexium™ MC12 multi carrier. Refer to Libraries and Example Project.

 WARNING
UNINTENDED EQUIPMENT OPERATION
  • Verify that the carriers, tools on the carriers, and products on the carrier tools are properly fastened so it cannot come loose even in the case of fast acceleration.
  • Take all necessary measures to ensure that the moving parts cannot move in an unanticipated way.
  • Verify that emergency stop equipment is operational and within reach of the zone of operation.
  • Verify that the system is obstacle-free and ready for the movement before starting the system.
  • Run initial tests at reduced velocity.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

If the power supply is disabled unintentionally, for example as a result of power outage, errors or functions, the carriers are no longer decelerated in a controlled way.

 WARNING
UNINTENDED EQUIPMENT OPERATION
Verify that movements without active braking capabilities cannot cause injuries or equipment damage.
Failure to follow these instructions can result in death, serious injury, or equipment damage.

The metal surfaces of the system may exceed 70 °C (158 °F) when subjected to heavy loads and/or high performance during operation.

 WARNING
HOT SURFACES
  • Avoid unprotected contact with hot surfaces.
  • Do not allow flammable or heat-sensitive parts in the immediate vicinity of hot surfaces.
  • Verify that the heat dissipation is sufficient by performing a test run under maximum load conditions.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
NOTE: Perform a start-up in case of an already configured Lexium™ MC12 multi carrier when it is used under modified operating conditions. For more information, refer to Specific Safety Information.

Commissioning Procedure

Step

Action

1

Verify the installation. For more information, refer to Verifying the Installation.

2

Verify that the loads conform to the appropriate specified forces and torques for components of the Lexium™ MC12 multi carrier before operating the system.

3

Perform initial tests at reduced velocity. During these tests, verify that the controller responds without any error or advisory message to the signals of the Lexium™ MC12 multi carrier.

4

Verify that the ambient conditions conform to the appropriate specified environments for the Lexium™ MC12 multi carrier. For details, refer to Ambient Conditions.

NOTE: The maximum permissible dynamic forces decrease with increasing velocities and depend on the load and the center of gravity.
