Clutch

With this drive combination with integrated auxiliary drive the system­specific
requirements set out in section 3, "Safety Notes", must be observed in all cases!
Changeover must be carried out only when the main and auxiliary gear units are at
a standstill.
The clutch is located on the output shaft of the auxiliary gear unit.
The coupling ring is shifted axially by a shift lever.
The end faces of the coupling teeth to be engaged on changeover are chamfered so as to enable the slight
rotary movement necessary for "tooth ­ space alignment" to occur automatically when the control sleeve
is shifted axially.
This is conditional upon at least one gear­unit shaft being freely rotatable when
changing over.
If, however, the teeth come together in such a way that shifting is no longer possible, the motor of the
auxiliary gear unit should be briefly run (inching operation) with the control lever in position "OFF" and the
locking plate engaged, and the shifting operation repeated or the clutch rotated slightly on the gear­unit
shaft.
After changeover the locking plate must be immediately locked.

Locking of the shift lever is indicated by a limit switch on the customer's evaluation instrument.
