5.3 STO! Power-fail message
The message STO! appears in the display as the machine is switched off or if the mains supply
voltage has fallen below specification.
The message STO! (store) indicates that the machine has stored some parameters internally
as a power fail condition was detected. The error output is switched active and the ready output
inactive simultaneously with STO! appearing in the display.
If the mains supply voltage only experiences a drop in level and then returns to a correct level
then the ready output is restored to its previous condition but the message STO! will remain in
the display to indicate that there has been a problem with the mains supply.
