E715 12V BATTERY MONITOR


This is a very easy to fit Unit that monitors the Vehicle’s Electrics and alerts the Driver via an Audible / Visual Device that the Battery is becoming exhausted or that the Charging System is becoming faulty.

This Unit is sold with separate Relay / Solenoid to suit the application.

OPERATION:-

The unit monitors the voltage of a 6 cell, 12 volt battery and can control a solenoid and a warning lamp/sounder.


The “low battery” voltage is factory set at 11.1V

The “reset” voltage is 13.5V.


If the battery voltage is above the “low battery” voltage, the solenoid is energised and the warning lamp/sounder output is off.


If the battery voltage drops below the “low battery” voltage, the solenoid is de-energised and the warning lamp/sounder output gives an interrupted output. In this state the current drawn by the unit is < 1mA plus the current drawn by the warning lamp/sounder.


At this point:-

OR

When the “ignition switch” is disconnected, one of two things can happen

  1. If the battery voltage has risen above the “low battery” voltage, the solenoid will remain energised.
  2. If the battery voltage is below the “low battery” voltage, there will be a delay of up to 30 seconds before the solenoid is de-energised and the warning lamp/sounder output gives an interrupted output.


Without using either the “override” or “ignition switch” pins, when the battery voltage rises above the “reset” voltage the solenoid is energised and the warning lamp/sounder output is switched off.
