Electric connection of the switch is realised at the central control at A1.X9:4 + 10.
Maximum current consumption of the brush motors (in practical use) must not exceed 30A per
motor on the 26 and 30“ disk brush decks. The maximum amperage for the 33“ disk decks is 40A.
Lower settings are recommended for longer motor life, run time and traction.
When checking the carbon brushes make sure that the scroll spring is pressing the carbon brush
against the commutator, does not contact the guide and that distance to carbon brush guide is
sufficient.
Replace the carbon brushes, if required.
