SUBSTITUTION OF THE PRE-INDEXING ELECTROMAGNET
SUBSTITUTION OF THE BRAKE MAGNET
AND ADJUSTEMENT OF THE AIR GAP
Remove the rear cover 011, disconnect the leads connecting terminal block to the motor, the brake and the thermal
probes (heat sensor). Unscrew screws 311, extract the motor unit 150. Disassemble the gear 015 and remount it
on the new motor unit. Mount the motor unit in the carcase and reconnect the electric wiring to the terminal block.
To check that the phases are properly connected, perform a tool change by calling up the nearest station ... if the
phases are properly connected, the change of station will take place by the shortest route, if the disk goes the long
way round then interchange two motor supply wires at the terminal block (phase rotation).
Replace the rear cover.
TOEM 120 - 160 - 200 - 250
090
Remove the rear cover 011, extract the motor unit 150 and the gear 015.
Disconnect the brake leads. Remove the defective brake magnet and substitute it with the new one.
Adjust the air gap (0,2 - 0,3 mm to be checked in a vertical position and acting on the distance pieces 090).
Reassemble the whole by following the above sequence in reverse.
Remove the top cover 044, remove the support 042, remove the washers 046a, extract the electromagnet 200.
Remove the rear cover 011 and disconnect the electromagnet supply leads.
Mount the new electromagnet in the carcase and fix it down with the two washers.
Replace the support complete with its proximity switch 301 and reset it (see page 28).
Connect the electromagnet lead wires to the terminal block (see electrical connection schemes page 11).
Replace top and rear cover.
