MasterShunt 500 – User and Installation manual
Battery abuse
Slow and deep discharges below the battery’s end voltage can reduce the expected lifetime of your
batteries dramatically. This item shows the number of battery abuse cycles. A large number of abuse
cycles might indicate small loads that stayed connected during a long period (for instance during
wintertime). Get your electrical installation examined by a qualified installer if abuse cycles happen
more than once!
Discharged state
This timer will start when the SOC is below the “start under level” and will stop when the SOC is
above the “stop above level” (with a DOD of 100%)

Discharged state
Counter that shows the number of times where the “start under level” has been reached.
Calculated CEF
Charging Efficiency Factor (CEF) of the battery bank. This value is used for the calculation of the
consumed Amp hours and the time remaining function. An efficiency of 70% indicates that the battery
bank is at the end of its lifetime and needs to be replaced.
Restarts
Setup resets
The number of times the setup has been reset. Factory setting = 0. Resetting clears all history values
except for this counter which is increased by one.
Power cycles
Counts the number of times the MasterShunt 500 has been disconnected from the battery.
Min/max history
Deepest disch.
Shows the deepest discharge. The deepest discharge should never be higher than the rated capacity
of the battery as specified by the battery manufacturer.
Volt at low Ah
Shows the voltage at the moment of recording the deepest discharge.
Highest voltage
Shows the highest voltage that was recorded. This voltage should never exceed the maximum
charging voltage as specified by the battery manufacturer.
Lowest voltage
Shows the lowest voltage that was recorded. This voltage should never exceed the minimum
charging voltage as specified by the battery manufacturer.
Alarm timers
Voltage high
The timer shows the total amount of time the [Voltage high] on the alarm menu was raised.
Very low voltage
The timer shows the total amount of time the [Voltage low] on the alarm menu was raised.
Very low battery
The timer shows the total amount of time the [Battery low] on the alarm menu was raised.
Warning timers
Low voltage
The timer shows the total amount of time the [Voltage pre low] on the alarm menu was raised.
Low battery
The timer shows the total amount of time the [Battery pre low] on the alarm menu was raised.
