7. Maintenance
The device is free of maintenance.
Battery exchange
Dependent on environmental conditions e.g. network strength or temperature and also highly depending on
the settings like e.g. standby time or frequency of data transmission the inserted battery is differently
discharged.
Completely it is possible, each for itself, to send about 3000 SMS or to carry out about 400 data transmission
with a data amount of respectively 128kB or to achieve about 400 hours standby time with one lithium
battery.
A typically run time of 2 years can be achieved e.g.:
at a daily standby time once a day for a half hour, or
at a daily data transmission of a fully stored water level sensor
with 128kB memory volume and a measuring interval of
4 seconds
A typically run time of more than 10 years can be achieved e.g.:
if the RDT module is only used for rare alarming cases, or
at a monthly transmission of the data of a water level sensor
with 128kB memory volume and a measuring interval or
2 minutes
The remaining battery capacity is measured internal in the device and is compared with the set available
battery capacity of the inserted lithium battery. At an adjustable remaining battery capacity a warning
message can be sent. It is suggested to change the battery at a remaining battery capacity lower than 30%
in order to guarantee always a sufficient safety function. After a battery change the battery counter must be
reset by using the operation software in order to have a correct remaining battery capacity measurement. If
the reset of the battery counter will not be done, a warning message can be generated, although the inserted
battery has enough remaining capacity.
If a lithium battery with a capacity is used that differs from the suggested standard battery, the capacity of
the alternative type can be set by the operation software.
After a long inactive time of the RDT module without resp. with an unloaded battery it can last up to 60
minutes after inserting a new battery before a GSM/GPRS RDT is already possible, because the internal
energy buffer (power buffer) must be reloaded.
The communication per PC interface is immediately functional after inserting a new battery.
For a battery exchange proceed like follows:
Screw completely off the cover of the battery receptacle at the
bottom side of the filler cap counterclockwise
(image 1).
Remove the old battery by pulling out
(image 2)
.
Put the new battery with the positive pole right into the
battery receptacle (

). The battery connection is
reverse polarity protected.
Screw-in in the cover of the battery receptacle clockwise till to
the stop (

).
When opening the cover of the battery receptacle the wasting
of the internal area of the device with humidity or dirt.
This can lead to abnormal behavior, reduced run time or
destruction of the device.
