The following data is backed up with this battery voltage: PLC program, RPA, TOA, SEA, SEA4, ZOA. Note The CSB module must not be removed from the subrack even if a battery is in place, because the data to be battery-backed is not physically on the CSB.
11 Maintenance Note 01.99 On the CSB, product version D, the operating points of the battery monitor have been adapted to the lithium battery. If you combine the CSB, product version C, with a lithium battery or the CSB, product version D, with an alkaline battery, it is possible that the advance warning time of 4 weeks or the backup time of 1 year cannot be maintained under adverse environmental conditions (temperature).
01.99 11.3 11 Maintenance Handling modules Nearly all the SINUMERIK modules have LSI chips. Owing to their technology, these are very sensitive to overvoltage and thus also to electrostatic discharge. Modules using these components are identified on the component side by this warning symbol. ELECTROSTATIC SENSITIVE DEVICES (ESD) can be destroyed by voltages and energy levels well below those perceived by the human body.
11 Maintenance 01.99 Therefore, please pay attention to the following guidelines: • Electronics modules must not be touched unless it is absolutely vital for the work to be done. • Before touching a module, any static in the body must be discharged. The easiest way to do this is by touching a conductive, earthed part of the structure (e.g. bare metal parts on the cabinet, socket earth contact) immediately beforehand. • Modules must not be brought into contact with materials that are good insulators (e.g.
