Verifying the Signals of the Limit Switches
The use of limit switches can help protect against some hazards (for example, collision with mechanical stop caused by incorrect reference values).

LOSS OF CONTROL |
oEnsure that limit switches are installed as determined by your risk assessment. oVerify correct connection of the limit switches. oVerify that the limit switches are sufficiently distant from the mechanical end to allow an adequate stopping distance. oVerify correct parameterization and function of the limit switches. |
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
oSet up the limit switches in such a way as to keep the motor from overtraveling the limit switches.
oTrigger the limit switches manually.
If an error message is indicated, the limit switches were triggered.
Parameters can be used to release the limit switches and to set them up as normally closed contacts or normally open contacts, see chapter Limit Switches.
