OPERATIONS TO BE CARRIED OUT
IN CASE THE POSITIONING CYCLE
HAS NOT BEEN COMPLETED
an emergency or accidental stop occurred
Call up from the console a "tool change" (the nearest one) keeping to the same direction of rotation that the turret
(the toolholder disk) had when it stopped. If this is not known and the "change" called for does not go through to
completion (namely not locking or bringing about the operation of the heat sensor), proceed as follows:
- Noted the direction of the disk rotated during the attempted (unsuccessfully) "tool change"; call up from the console
the nearest station which can be reached by rotating the disk from its present position in the opposite direction to
that of the previous attempt.
If the control refuses to accept a "tool change" starting from the condition of "turret unlocked", then carry out the
necessary operations manually as follows:
- Remove the rear cover 011 and the top cover 044, unscrew and partially extract the wire clip 058, disconnect the
motor and the brake leads from the terminal block 310 (still keeping the proximity switches connected; please note
the order of the motor wires, in order to avoid wrong connection at the end of operations).
Using a hexagonal spanner (see table) turn the motor shaft 012 by hand so that the toolholder disk rotates in the
same direction as it did when it stopped and at the same time push the core 073 of the electromagnet 200 until the
latch 017 enters a recess in the divider 005.
Keeping the core pushed reverse the rotation of motor shaft until the red indicator of proximity switch 313 lights
up and can be seen from above through the hole (n).
Make the shaft rotate for another turn but working so that the indicator still remain lit.
If the direction in which the disk was rotating when it stopped is not known and a mechanical block is encountered
after the reversal and the turret will not lock, the shaft must be made to rotate in the same sense as that proceeding
the reversal.
Screw on the wire clip, reconnect the leads to the terminal block (care the phases of the motor leads), replace top
and rear covers.
