DIP SWITCH SETTINGS
16 July 2010 / Mass Charger 12/60-2; 12/80-2; 24/50-2; 24/75; 24/100; 3-24/100; 48/25; 48/50 / EN
5 DIP SWITCH SETTINGS
The Mass Charger settings can be adjusted in two ways:
• By means of DIP-switches;
• Via the MasterBus network (by means of a remote
control panel or an interface connected to a PC with
MasterAdjust software); see chapter 7.
Once a DIP switch has been set to On,
MasterBus settings are disabled.
CAUTION!
Invalid settings of the Mass Charger can cause
serious damage to your batteries and/or the
connected load! Adjustments of settings may be
undertaken by authorised personnel only.
5.1 DIP SWITCH OPERATION
The Mass Charger has six DIP switches, see figure 9.
These switches are operated by flipping the levers to the
other position, using a small screw driver.
5.2 DIP SWITCH FUNCTIONS
See the table below for the functional overview of the six
DIP switches (Switch 5 and 6 are reserved for future use).
5.2.1 Force Float (DIP switch 1)
For special applications a fixed charge voltage can be
required. The battery charger allows you to change the
three stage charge program to a single stage program by
activating the function "Force Float", switching DIP switch
1 to "ON" (see fig. 2 & 3 for further information).
The charge voltage will be fixed at 13.25V (12V charger),
26.5V (24V charger) or 53V for a 48V charger.
5.2.2 Traction setting (DIP switch 2)
Setting for traction charging: +0.7/1.4/2.8V during bulk and
+0.4/0.8/1.6 V in absorption for 12/24/48V batteries.
5.2.3 Gel batteries (DIP switch 3)
Some gel batteries need a higher float voltage for optimal
charge. Changing the float voltage can by done by setting
DIP switch 3 to "ON". The float voltage will increase to
13.8V (12V charger), 27.6V (24V charger) or 55.2V for a
48V charger.
5.2.4 Diode setting (DIP switch 4)
Setting for +0.6 V compensation in case a battery diode is
used.
1 = ON; 0 = OFF
ContMon: Continuous monitor mode. MasterBus,
RS232 and DC-alarm stay functioning at
mains failure. Remote stays functioning if it
has its own power source.
Diode: Diode compensation on (+0.6V)
Gel: Gel compensation on (+0,55V during float)
or 1.1V/24V or 2.2V/ 48V
Traction Traction charging (+0.7V during bulk and
+0.4V in absorption).
Force float: One step charge program with fixed float
voltage.
