The new toothed belt must not be stretched or kinked. 14
➠ Place the new toothed belt of the conveyor in the guide channel of the fixed side of the con-
veyor.
➠ Carry out DOOsteps in the reverse order to those taken during removal (see section 14.3.2.2).
➠ Check: The toothed belt for the conveyor must be engaged in DOOsynchronizing disks RYHU

➠ Make certain that the polarity of the motor terminals (+/-) is correct (= correct direction of rota-
tion).
➠ Fasten the motor cable to the circumference of the geared motor with the heat-shrinkable
sleeve.
CAUTION O
The connecting cables for the sonar proximity switch must not be damaged or kinked. 14
➠ Where applicable, install the sonar proximity switch mount incl. sensing head.
➠ Fasten the EHOWJXLGHV(see -> 2) in the slots in the correct position (two M3 hex socket head
cap screws):
– The toothed belt must be in contact with the upper edge of the conveyor assembly
along its entire length and must not be under tension in the remaining area.
➠ Install the guide rails on the fixed side of the conveyor assembly.
➠ Adjust the DOLJQPHQWRIWKHJXLGHUDLOV(see section 14.3.7).
➠ Carry out the pertinent "Final steps including function check" (see section 14.4).
In the process, make certain the geared motor rotates in the correct direction.
