NAJm board in the dentist element
✔
You have replaced the NAJm board.
1. Unplug any dongles (J11, J12, J13) from the defective board and plug
these into the new board.
2. Establish the same jumper setting of S1 as on the old board.
7.3.6
NWEm board in the water unit
Tip: Cover the ventilation slots above the power supply when changing
this board. This ensures that no screws can fall into the slots.
If a connector on X2 is equipped with a 4.7 kOhm resistance bridge on X2
(4->5), this plug must be replugged into the new NWEm board. This is the
case of no amalgam separator, no automatic separator and no Dürr wet
suction system are installed.
