Adjustme
nt of the settings of the ChargeMaster can be
made in three different ways:
• By means of DIP-switches; see section 5.1;
• By means of settings at the LCD-display; see section
5.2;
• Via the MasterBus network (by means of a remote
control panel or an interface connected to a PC with
MasterAdjust software); see section 6.3.
CAUTION!
Invalid settings of the ChargeMaster 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 SETTINGS
The ChargeMaster has four DIP switches at the bottom
side of the housing. See figure 8.
Figure 8: DIP-switches
5.1.1 DIP-switch 1: Battery type
The factory default for the battery type is optimal for most
installations. In some applications however, it is desirable
to change this setting.
Standard open lead/acid battery (factory setting) OFF
Gel / AGM / spiral battery (see specifications) ON
5.1.2 DIP switch 2: Charge algorithm
IUoUo, fully automatic / 3step+ (factory setting) OFF
Constant voltage charging (Float = 13.25/26.5V) ON
5.1.3 DIP-switch 3:Stand-by mode for display
By default the LCD-display will switch off after 2 minutes if
either the Chargemaster is switched to Stand-by or the AC
power supply is disconnected.
LCD-display will switch off when Chargemaster is
switched to stand-by mode (factory setting)
OFF
LCD-display will stay on when Chargemaster is
switched to stand-by mode. Note that the LCD-
display is powered by the batteries.
ON
5.1.4 DIP switch 4: Equalize mode
WARNING
Incorrect use of the equalize mode may lead
to hazardous situations.
Do not smoke; use any naked flame or other
sources of ignition due to risk of explosion.
Always ventilate the room were the batteries
are located and equalized to clear the air.
Equalization is ONLY applicable for wet type
batteries and will damage gel and AGM type
batteries.
An equalizing charge can be necessary after very deep
discharges and/or inadequate charges. This has to be
carried out according to the specifications of the
manufacturer of the batteries.
During equalizing the batteries are brought into the gas
state and is it possible that the permitted load voltages are
exceeded. Therefore appropriate measures must be
taken, e.g. disconnect all loads from the battery and
ventilate the room. For these reasons use of the equalizing
mode should only be executed by trained technical
engineers.
The equalizing mode can only be started when the
Chargemaster is in operation and in Float. This means that
the connection compartment of the Chargemaster must be
opened while connected to the mains and the batteries.
Take adequate measures for protection against short
circuits and electrical shocks.
To start the equalize mode: move DIP switch 4 to the ON
postion and back to the OFF position.
