Operating Instructions Before operating the battery charger, ensure that the charger is assembled and installed as per the installation instructions. WARNING: DANGER OF INJURY OR DEATH Before connection, disconnection or handling of Guardian battery charger, be sure AC power supplies are off. - Page 12 The BCEG-12-10 and BCEG-24-10 models are fitted with a self-resetting polyfuse on the DC output. If reverse polarity or short circuit faults occur, turn off AC power and disconnect the outputs. This will allow the polyfuse to reset. The charger can then be re-connected and switched back on.
- Page 13 Over Voltage, Under Voltage, and Charge Fail Connection In a de-energized state the COM – N/C contact is alarmed. The relay energizes on power up and changes state to COM – N/O. These contacts are volt-free contacts rated at 1A @ 30VDC.

Page 15: Measuring Charging Voltage And Current
Measuring Charging Voltage and Current To check the charger is working, follow these steps then consult the expected conditions listed below. 1. VOLTAGE – Place voltmeter across battery terminals (“V” in diagram). 2. CURRENT – Turn off AC power supply before breaking into the line to measure DC Amps. -
Page 16: Using Correct Size Battery Charger
Using Correct Size Battery Charger The battery charger will need to provide both the standing load and minimum charge current. If a charging current of 2 amps is required, and the standing load is 1 amp, then the charger needs to be able to output a total of 3 amps. - Page 17 NOTE: On this method, providing batteries have been sized correctly for engine and charged correctly, an open terminal voltage of 12.5V or greater should be present. The following table is for Lead Acid batteries with removable vent caps that can have electrolyte or distilled water added to them for routine maintenance.
