E860 24V BATTERY MONITOR WITH
135A ELECTRONIC OVERLOAD TRIP
135A ELECTRONIC OVERLOAD TRIP
This unit was designed to monitor the voltage of a battery and switch power to an external circuit. An electronic overload trip is included this disconnects the power if the current taken by the external circuit exceeds 135A.
During normal operation the Amber lamp indicates that the supply is connected to the external circuit.

1. The “W” terminal on the alternator. This connection ensures the alternator is charging the battery before the warnings are stopped and the supply is reconnected
Electronic Overload Control:
If at any time the average current drawn by the external circuit exceeds 135A then the power will be disconnected and the Amber lamp is switched off. Pressing the reset button resets the Overload circuit, on releasing the button power is reconnected and the Amber lamp switches on.
Note: pressing and holding the reset button disconnects the supply for as long as the button is pressed
Battery Voltage and Overload Control:
Pressing the reset button whilst the battery is disconnected by the battery monitor has no effect.
If after an overload and whilst the external circuit is disconnected the battery becomes low, then the battery monitor circuit takes control and after the 4 minute timed period resets the overload circuit. Power will then be automatically reconnected to the external circuit. The battery monitor will continue with the 2 minutes warning etc.

2. A momentary switch to the battery positive. This immediately stops the warnings, reconnects the supply and resets the timers. If the battery voltage is not raised to 26V the supply will be disconnected as above.
3. The ignition switch. This immediately stops the warnings and reconnects the supply the engine does not need to be running. Continued use in this way will result in a flat battery.
4. If the “start” connection is not used the supply will be reconnected when the battery voltage reaches 26V.
Battery Voltage Control:
Once the battery voltage has dropped below 23.5V for more than 30 seconds the Red lamp flashes and the Piezo sounds. If the battery voltage is not raised to 26V within 2 minutes the E860 disconnects the supply for 4 minutes during this period the Amber lamp is off, the Red lamp and piezo remain on continuously.
This 2 minutes, four minutes cycle is repeated until the battery voltage is raised to 26V.
An optional “Start” connection is provided, which reconnects the supply and resets the timers this can be activated by one of the following:
