MPI-520 OPERATING MANUAL version 3.4
Note:
- As a result of interferences in the network it is possible that the process of charging of accumulators
will finish too fast. In the case too short a time of charging is detected it is necessary to remove the
plug of the charger and start charging anew.
Additional informations displayed by the meter
Battery connection error!
Excessive voltage
at the accumulator
package during
charging.
Check the contacts of the accu-
mulator package. Should the
problem persist, replace the
package.
No communication
with the accumula-
tor controller or bat-
teries compartment
put in.
Check the contacts of the accu-
mulator package. Should the
problem persist, replace the
package. Put the accumulators
compartment instead of batte-
ries.
Battery temperature too
low!
The ambient tem-
perature is lower
than 10C
It is not possible to charge the
accumulators correctly in such a
temperature. Place the meter in
a warm place and commence the
charging mode anew.
The present message may be
displayed also in the case of
deep discharging of the accumu-
lators. It is then recommended to
try to turn the charger repeatedly.
A damaged or
deeply discharged
accumulator pack-
age
The message is displayd for a
while and then the precharge
process begins again. If after
several attempts the message:
Battery temperature too high!
is displayd, replace the package.
6.4 General principles regarding using Ni-MH accumulators
- If you do not use the device for a prolonged period of time, then it is recommended to remove the
accumulators and store them separately.
- Store the accumulators in a dry, cool and well ventilated place and protect them from direct sunlight.
The temperature of the environment in the case of prolonged storage should not exceed 30ªC. If the
accumulators are stored for a long time in a high temperature, then the occurring chemical processes
may reduce their lifetime.
- Accumulators NiMH resist normally 500-1000 charging cycles. The accumulators reach their maxi-
mum capacity after being formatted (2-3 charge and discharge cycles). The most important factor
which influences the lifetime of an accumulator is the depth of discharge. The deeper the discharge of
the accumulator, the shorter its lifetime.
- The memory effect is limited in the case of NiMH accumulator. These accumulators may be charged
at any point with no serious consequences. However, it is recommended to discharge them complete-
ly every few cycles.
