11.2 Operating States
The modules of the ES800 system can have one of the following operating states:
11.2.1 "Off" Operating State
The ES800 Base Module (e.g. ES801.1) of the ES800 system is physically separated
from all operating voltages or the external power supply is completely switched
off.
The modules of the ES800 system are switched off and the Embedded PC of the
ES820.1 Drive Recorders is shut down.
11.2.2 "Standby" Operating State
In the "Standby" operating state, all modules of the system are supplied with
power but are deactivated. The modules connected to the interfaces are not
being triggered. The current consumption is minimal.
The Embedded PC of the ES820.1 Drive Recorders can have one of the following
Standby operating states:
- "Low power standby" operating state and
- "Fast boot standby" operating state.
The system remains in the "Standby" operating state until it switches to the "On"
operating state following a "Wake-Up" event.
"Low power standby" Operating State (ES820.1)
In the "Low power standby" operating state, the Embedded PC of the Drive
Recorder is in the idle state ("Hibernate", "Suspend-To-Disk"). The current con-
sumption of the ES820.1 in this operating state is low.
In the "Low power standby" operating state, the current status and available set-
tings are stored in the hibernation file.
The "Wake-Up" function is activated and the ES820.1 switches to a different oper-
ating state depending on the configured event.

NOTE
The ES800 Base Module (e.g. ES801.1) must be physically disconnected from all
operating voltages so that the ES800 system does not take on any current.
