15AP2 Secondary board
The secondary board is fitted on the main transformers 15TM1, 15TM2 and the diode
modules 15D1, 15D2.
On page 48 there are instructions on how to check the secondary board.
15AP2:1
Diode modules
The diode modules comprises two diodes each, rectifier and freewheel diode.
During the time interval between two voltage pulses, the freewheel diode
maintain the welding current from inductor 15L3.
If a diode module has failed, both diode modules must be replaced and fitted in
accordance with the instructions on page 54.
15AP2:2
Temperature monitoring
NTC D1 and NTC D2 are fitted inside the diode modules 15D1 and 15D2.
NTC R28 is fitted on the copper foil of circuit board 15AP2.
The temperature monitoring circuit operates when the temperature exceeds
110
