Preventive replacement of control auxiliaries.For critical power applications it is recommended to replace the MicroLogic trip unit and the control auxiliaries after 10 years. In case of harsh environmental conditions, it may be required to reduce this time: see Harsh Conditions and Device Not Installed Inside a Switchboard. Schneider Electric will help you to define the most appropriate and adequate maintenance plan specific to you application.*

Test the device control, the uploading of contact status (OF, SD, SDE) operation of optical link, by using the communication network.

Service Interface+ EcoStruxure Power Commission software

Test by using the communication network:

• Uploading of chassis position contacts

  .

• Synchronisation of the address between BCM ULP and IO module

  .

• Forced replication of the BCM address.
