4.5.6.2 Replacing the main rechargeable battery
You can replace the main rechargeable battery during operation. The rechargeable buffer
battery supplies the power while the main rechargeable battery is being replaced. The
maximum bridging time is 20 seconds. If you exceed the buffer time, the HMI device will
switch off.
During the bridging time, the following features are disabled:
● Display backlighting
● All LEDs except for "SAFE" and "RNG"
● The illuminated pushbuttons
● The USB ports
Note
Read the section "Safety instructions (Page 72)".
If the capacity of a rechargeable battery drops to 50 percent of the original capacity
, use
a new rechargeable battery. A new rechargeable battery is needed after 500 full charge
cycles.
Example of a full charge cycle:
The charge level of a rechargeable battery decreases from 100 percent to 80 percent.
The rechargeable battery is charged again in this state and then reaches 100 percent.
Discharging to 80 percent and recharging to 100% adds up to a full charge cycle.
Keep main rechargeable batteries in stock.
