Safety Features - MASCOT 205110 Bedienungsanleitung

The embedded microprocessor & charge program has numerous
• The -dV level will adapt to the number of cells
and will be approximately equally sensitive for
all number of cells.
• The safety timer will protect the batteries if a
-dV signal fails to appear during charging. It is
normal to have a safety timer that is longer than
the max. charge time.
• Some battery cells may give a voltage drop
during the initial part of the charge cycle. To
avoid interruption of the charge cycle the char-
ger has a timer that prevents -dV detection
during the first minutes of the charge cycle.
• The charger is programmed to disregard large
voltage fluctuations due to connection of exter-
nal loads etc. Such false -dV signals will be de-
tected by the software and will be disregarded.
• Top-off charge following –dV detection ensures
that all cells in a battery pack reaches full capa-
city (are balanced) prior to trickle charge.

Safety features

features for safe battery charging
• The charger output is protected against reverse
polarity, in most cases by an automatically re-
settable fuse.
• The charger is designed for the lowest possible
leakage current from the battery when mains is
disconnected (<1mA). Even so, it is recommen-
ded that the batteries are disconnected from the
charger when mains is not connected.
• On request the charger may be supplied with
battery temperature monitoring. A built-in tem-
perature change control (+dT/dt) secures opti-
mal charge with a built-in NTC resistor in the
battery pack.
• Other functions such as 0dV detection and
timer only charge is available upon request.
Most charge parameters may be altered using
an external programming tool. Contact Mascot
for details.
