6.2.1.2 Fitting and testing the input and center conveyor geared motors
●
Insert the new geared motor. Make sure that the toothed belt is positioned correctly around the synchroniz-
ing disk.
●
Mount the geared motor using the 4 M3 slotted head screws.
●
Refer to the circuit diagram folder to make sure that you have connected the motor up correctly.
●
Attach the power supply cable with the two heat-shrinkable sleeve rings.
●
Referring to the adjustment instructions, carry out a function test of the conveyor.
NOTE
OOO
While carrying out the function test do not fail to observe the safety instructions in Chapter 1.
●
Unlock the key-operated switch before performing function testing and making adjustments. This will allow
you to take measurements at the motors with the protective cover open. However the gantry axis systems
will be in a de-energized state.
NOTE

When you have finished the function test do not forget to lock the key-operated switch again, stowing the
key in a place where unauthorized persons have no access to it.
