The Ventam 65 MHE Charging Interlock system – This system will interlock the extraction fan in a battery charging room to the electrical supply to the battery charger circuits. If the extraction fan is not turned on or if it fails in service, the charging circuit will be isolated and the panel will indicate both “Fan Off” and “Charger Power Off”. Each time the fan is stopped or the emergency stop button is pressed the “Charger Power Reset” pushbutton must be pressed to reset the system. Fan status indication, charger circuit indication and the emergency stop button are fitted to the panel front.
This system is required to extract gases produced during battery charging and is suitable for any similar system.
