Crown Charger Module FS3-MP124-2

Warning: This service requires trained personnel with PPE!

Air inlet filter free from dirt build up?

Charger Modules' airflow monitoring functional?

Charger Modules' cooling air supply healthy?

Note: A blocked filter will affect the cooling ability, reduced airflow could lead to the Charger protecting itself by backing off the output power and eventually shutting down.

Power modules backed off due to over temperature?

Note: Having the power modules back off due to over temperature will cause longer charge times and the inability to charge the battery correctly, units operated with blocked filters for extended periods will result in premature failure of the Charger Module cooling fans.

1. The filter material is an electrostatic polypropylene type that is easily cleaned with compressed air or in extreme situations washed with clean soapy water

2. Before attempting to clean the filter it is necessary to remove it from the housing and taken to an appropriate place to be cleaned

3. If it is washed it must be left to dry fully before being refitted to the charger, drawing moist or wet air into the Charger Modules could cause failure of the modules

Accordingly when the filter is inspected, the front air inlet grills of the Charger Modules should be inspected for excessive signs of dirt build up. Should the Charger modules be covered in dust they should be removed from the housing for close inspection of any external signs of damage or corrosion. If it is just a build-up of dry dust the Charger Module should be cleaned out;
