6.3.1 Monitoring
Value
Meaning
General
Device state
Shows the state of the Alpha Pro: Standby/ Charging/ Alarm
Charger state
Shows the state of the regulator: Off/ Bulk/ Absorption/ Float/ Stopped
Battery
Battery voltage
Battery voltage measured by the Alpha Pro charge regulator [V]
By default this is sense voltage, see below. When a shunt device is selected, this is the
voltage on that shunt device.
Battery temp.
Battery temperature measured by the by the Alpha Pro charge regulator [°C].
Alternator
Alternator volt.
Voltage measured between +Bat (red wire) and GND (black wire) of the Alpha Pro
charge regulator's cable loom
Sense voltage
Battery voltage measured by the Alpha Pro charge regulator [V] on 'reg on' (brown wire)
Field current
Current through the alternator field coil [A]
Alternator temp.
Alternator temperature (with installed sensor on the alternator). Refer to section 6.3.4 for
settings
Alternator shaft
Number of revolutions alternator [rpm]
Engine shaft
Number of revolutions engine [rpm] (only if a pulley ratio is entered in Configuration tab)
Shunt
Status
Not selected/Connected/Connection lost
State of charge
Battery state of charge (SOC) 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]
Notes: - When the configuration is unlocked, only Device state and Charger state will be shown.
- "Alternator shaft" and "Engine shaft" will not be shown if the RPM group is disabled in the Configuration
tab.
6.3.2 Alarms
Value
Meaning
Temp.sense error
Temperature compensation error
Bat. temp. high
The battery temperature sensor measures a high temperature
APR. temp. high
Alpha Pro charge regulator device temperature too high
Battery high
Battery high voltage warning, generated by the Alpha Pro
Battery low
Battery low voltage warning, generated by the Alpha Pro
High field curr.
Field current too high, Alpha Pro charge regulator stops regulating and retries after 5
seconds repeatedly
Low field curr.
Field current too low, there is a disconnection in the field wiring
+D overload
Overload of the lamp connection (current too high)
Cable losses
Voltage drop is higher than 0.9 V. The cable between alternator and battery is too thin.
Shunt mismatch
Different voltage settings of MasterShunt and Alpha Pro
Invalid system
This alarm is only applicable for the Alpha Pro II. It indicated that the charging mode
selector is on a blank spot. The selector has two blank spots to separate 12V, MasterBus,
24V. The yellow LEDs will blink twice, one after the other.
6.3.3 History
Value
Meaning
Total run time
Total regulator charge time since commissioning
# APR temp. high
Number of temperature alarms
# High DC alarms
Number of high DC voltage alarms
# Low DC alarms
Number of low DC voltage alarms
