Division of the system into zones
You can divide a system into various zones or functional areas by using numerous
connection boxes. You can also set up the safety functions zone-dependently. This means
that both enabling buttons and STOP buttons can act in only one particular zone and not in
others.

Rechargeable buffer battery
The rechargeable buffer battery avoids the need to restart the Mobile Panel when changing
between different connection boxes.
The maximum buffer time is 10 minutes. The rechargeable battery is able to bridge the buffer
time 5 times without recharging. During the buffer time, the backlight of the display is
switched off.
When the mobile panel is connected to a connection box, the rechargeable battery is
charged automatically.
