6.3 MASTERBUS FUNCTIONS
Adjustment of the settings of the Alpha Pro II can be
made via the MasterBus network (by means of a
remote control panel or a MasterBus - USB interface
connected to a PC with MasterView System
software).
CAUTION!
Invalid settings of the Alpha Pro II can
cause serious damage to your batteries
and/or the connected load! Adjustments
of settings may be undertaken by
authorised personnel only.
6.3.1 Monitoring
General
Device state Shows the state of the Alpha Pro II: Standby/ Charging/ Alarm
Charger state Shows the state of the internal charger: Off/ Bulk/ Absorption/ Float
Battery
Battery voltage
Battery voltage measured by the MasterShunt or, if no Mastershunt has been selected, the
battery voltage is measured by the Alpha Pro II [V]
Battery temp.
Battery temperature measured by the MasterShunt or, if no Mastershunt has been
selected, the battery temperature is measured by the Alpha Pro II [°C]
Alternator
Alternator shaft Number of revolutions alternator [rpm]
Engine shaft Number of revolutions engine [rpm]
Sense voltage Battery voltage measured by the Alpha Pro II [V]
Field current Current through the alternator field coil [A]
Alternator volt. Voltage measured between +Bat and GND [V]
Alternator temp. Alternator temperature, mount the sensor on the alternator. Also refer to section 6.3.4
Shunt
Status Not selected/ Connected/ Connection lost
State of charge Battery state of charge calculated by the shunt [%]
Battery voltage Battery voltage [V] measured by the MasterShunt
Battery current Battery current [A] measured by the MasterShunt
Battery temp. Battery temperature measured by the MasterShunt temperature sensor [°C]
6.3.2 Alarms
TS error Temperature Compensation error
Bat. Temp. high The battery temperature sensor measures a high temperature
Dev. Temp. high Alpha Pro device temperature too high
+D overload Overload of the lamp connection (current too high)
Invalid system
Selector on a blank spot. The selector has two blank spots to separate 12V,MasterBus,24V.
The yellow LEDs are blinking twice alternately.
Battery high Battery high voltage warning, generated by the Alpha Pro II
Battery low Battery low voltage warning, generated by the Alpha Pro II
High field current Field current too high, Alpha Pro II stops regulating and retries after 5 seconds repeatedly
Low field current Field current too low, there is a disconnection in the field wiring
Cable losses Cable between alternator and battery is too thin, causing voltage drop
Shunt mismatch Different voltage settings of MasterShunt and Alpha Pro II
