3.5 SMART TERMINAL - OUTPUT 3
The Chargemaster is equipped with three full outputs. The
total output current is divided over these three outputs.
See section 4.6 for connections.
Output 3 is the Smart terminal, which can be current
limited and can serve as an output and as an input to
charge battery 1 & 2.
The Smart terminal has the following operating modes:
10A starter
Starter
Starter + alternator
Follow main
Follow main + alternator
12V constant voltage
24V constant voltage
12V 3 step+
3.5.1 10A starter
Output 1 & 2 are configured as full outputs, Smart terminal
3 is now current limited to 10A to safely charge a starter
battery.
3.5.2 Starter
Output 1 & 2 are configured as full outputs, Smart terminal
3 is now current limited to be able to charge a starter
battery. A 24V charger can charge a 24V or 12V starter
battery with an own charging profile. Settings are
configured via MasterBus, see section 5.2.
3.5.3 Starter + alternator
Output 1 & 2 are configured as full outputs, Smart terminal
functions as a VSR (Voltage Sensitive Relay). When there
is no AC power available and the alternator is charging the
starter battery, the alternator can also be used to charge
battery 1 & 2. The threshold voltage which is used to
switch over can be configured via MasterBus. See section
5.2
3.5.4 Follow main
Operation mode for 3 batteries, the charger is configured
with 3 full outputs. All batteries are charged with the same
settings.
3.5.5 Follow main + alternator
Operation mode for 3 batteries, the charger is configured
with 3 full outputs. All batteries are charged with the same
settings. Smart terminal functions as a VSR (Voltage
Sensitive Relay). When there is no AC power available
and the alternator is charging the starter battery, the
alternator can also be used to charge battery 1 & 2. The
threshold voltage which is used to switch over is
configured via MasterBus. See section 5.2
3.5.6 12V constant voltage
Output 1 & 2 are configured as full outputs, Smart terminal
is now current limited and set to 12V constant voltage
3.5.7 24V constant voltage (24V model only)
Output 1 & 2 are configured as full outputs, Smart terminal
is now current limited and set to 24V constant voltage
3.5.8 12V 3 step+ (24V model only)
Output 1 & 2 are configured as full outputs, Smart terminal
is now current limited and set to 3 step+ charge algorithm.
In 12V 3 step plus configuration the following battery types
can be selected: AGM, GEL, flooded, AGM Spiral.
3.6 MAINTENANCE
No specific maintenance to the ChargeMaster Plus is
required. Examine your electrical installation on a regular
basis, at least once a year. Defects such as loose
connections, burnt wiring etc. must be corrected
immediately.
If necessary, use a soft clean cloth to clean enclosure of
the ChargeMaster Plus. Do not use any liquids or
corrosive substances, such as solvents, alcohol, petrol or
abrasive components.
3.7 FAILURES
The ChargeMaster Plus is protected against overload,
short circuit, overheating and under and over voltage. If a
fault condition occurs, the MODE button turns red and the
Battery 1, 2 & 3 LED indicate an error code. See section
3.3.3 for explanation.
CAUTION!
The ChargeMaster Plus is not protected
against serious over voltage (>275VAC) on
the AC-input .
As long as there is no error code shown, no
failure is detected: the ChargeMaster Plus is
operating normally!
3.8 HISTORICAL DATA
Connect the ChargeMaster Plus to MasterBus in order to
be able to see the historical data stored in the
ChargeMaster Plus.
