detected by means of
plausibility checks.
Detected implausibilities are
highlighted by a question mark
symbol. Please refer to chapter
parameter setting for detailed
information.
Quality of the power supply
A hardware circuit ensures that
the device can only be used, if
the power supply is in the range
specified by the technical data.
If the supply voltage is too low,
the device will not start up or it
will be set out of service
respectively.
Sags of the supply voltage
Short-term sags of the supply
voltage are detected and can
be bridged in most of the cases
by means of the integrated
buffer within the power supply
hardware.
This buffer also allows the
termination of ongoing data
writing procedures.
The module for the supervision
of the system utilization will
detect repetitive short-term
sags of the supply voltage.
Internal data of the device
(memory load, internal
resources, ...)
An internal module monitors the
system utilization.
The module for the supervision
of the system utilization
initiates in case of a fatal error
a reboot of the device. In case
of minor faults the system led
will flash alternating red and
green (please refer to the
Troubleshooting Guide). The
issue will be recorded as a
system message.
Battery
The battery is monitored
continuosly.
Notice: The battery serves as
buffering of the clock (real time
clock). There's no impact on the
functionality of the device if the
battery breaks down, except for
the buffering of the clock while
the unit is in de-energized
condition.
If the battery is low the System
LED will flash alternating red
and green (please refer to the
Troubleshooting Guide).
Status of the device
communication (SCADA)
The projected and activated
SCADA module supervises its
connection to the master
communication system.
You can check if there is active
communication with the master
system within menu
