6.4.1.2 Function Test
● Carry out a function test as specified in the adjustment instructions.
NOTE OOO
With the function test do not fail to comply with 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 O
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.
