Please note: These measures are only for machines with Siemens control S5, S7, operator panels from Siemens and for the machine types FT-81 and MDC-xy. For machines with installed PC, like P-45x, P-460, PA-49x, as well as for the FPC-105 and the FPA-300 no measures are necessary.
Method 1
Do not power off the 24VDC for the Siemens CPU and for the panel (this may cause that the long-term condenser gets unloaded and programs and/or recipes and parameters might get lost). You can switch off the breakers for the main motors and other consumers but ensure that the CPU is still powered up.
In case the connection with the software has been lost due to the long-term stop, you can reload the Siemens CPU with the different memory cards of the CPU. Please additionally export all your recipes to a local storage device, like a USB stick.
When a Buffer battery is installed, ensure that it is full.
Method 2
Take screenshots from ALL the pages on the screen, also from pages with parameters and so on.
This is needed for a re-start of the machine in case you have lost recipes and parameters. Ensure that you have the correct program memory card ready.
Attention: Not all parameters are stored inside the recipes, therefore it is necessary to take screenshots from all the pages.
P-433 with B&R PC and installed S7 card: The buffer battery on integrated S7 card can get unloaded and parameters will get lost. Keep the PC constantly powered.
On restart of machines
Machines with CT drives (Digitax) and a dehumidification system: Switch on the machine, put emergency stop on and wait for at least 30 minutes to get the humidity inside down.
