Grinder print 230Vac / 230Vdc
This grinder circuit board converts 230 Vac (alternating
current) into 230 Vdc (direct current) with a rectifier to
drive the grinder motor.
The IM1 signal (24 Vdc) from the main control is
connected to connection J5-J6 (the red LED lights). This
signal controls the grinder motor with a triac.
This control can be accessed by removing the rear wall.
• Fuse 3.15 A S art.no. 02580: To protect the grinder
motor.
