Limit Switches - Festo YXC Series Description

8 Commissioning
8.2

Limit switches

Proximity sensors are mounted as limit switches.
If the proximity sensors need to be moved, the following must be observed:
• Mark position of the proximity sensors before moving, so the normal position can be reset if re­
quired.
• Observe the tightening torques (è accompanying operating instructions for the proximity sensors).
• Adjust the slot covers correspondingly.
• Check handling system for collisions.
• Check correct position of proximity sensors in a test run.
8.3 Test run
Before final commissioning, the commissioner must do the following.
1. Remove remaining safety components of the moving components
(è 2.4.3 Securing during transport and mounting).
2. Perform travel check at crawling speed
– Determine directions of movement. For even with identical control, motors/gears of the same
design can turn in the opposite direction due to different connection/mounting.
– Check function of the limit switches.
3. Start test run at crawling speed:
– Increase speed step-by-step up to the maximum necessary travel speed.
– Eliminate malfunctions that occur (è 12 Fault clearance).
4. Exit the test run.
