Checklist RMA

RMA Checklist on the PDL inspection lamp

Before a PDL lamp is going to be sent back to Alcochem Hygiene for a service / inspection handling
please make sure that following items have been checked:

Only use the original batteries in combination with the PDL

• The original batteries of the PDL offer a specific voltage to ensure that the UV-A LED will operate for a longer period of time. Non-genuine 18650 batteries often come with a lower voltage setting, which creates problems with the operation of the UV LED lamp circuit. Therefore make sure that you only use the PDL with the original, genuine batteries.
• To avoid battery fatigueness make sure that the batteries are charged at least once a year in a separate battery charger. ( parallel charger) This will ensure a regeneration of the cells and offer a prolonged lifetime.

An internal temperature switch may switch off the PDL,
if a critical temperature has been reached.

• In UV-A setting, the PDL offers 5 x 5 watt of UV-A power. This offers the UV intensity needed to carry out a thorough inspection.
• At this power level the temperature rises fast and after 10 to 15 minutes the PDL reaches its critical temperature of 60 degrees Celsius.
• At this temperature the power is switched off (this to prevent that the temperature will create internal damages).
• The PDL than needs to be cooled down for a certain period of time. To lengthen the operational time of the PDL: Make sure that you switch off the PDL in between the inspection moments.

Aluminium powder dust in the tail part and battery shaft
can create a problem.

• If the batteries are swopped out frequently please ensure that Aluminium powder dust, coming from the threading of the battery shaft, is not creating a problem with the operation of the PDL. A separate instruction sheet on the cleaning of the PDL is available on request.
