6.3.1 Proximity sensor (Stack magazine, ejecting cylinder)
The proximity sensors are used for end position sensing of the cylinder. The
proximity sensor is sensitive to a permanent magnet mounted on the piston of the
cylinder.
Prerequisites
Stack magazine module is assembled, proximity sensors are pre-assembled.
Cylinder is tubed up.
Compressed air supply switched on.
Proximity sensor is wired up.
Power supply unit switched on.
Execution
1. Use the manual override of the solenoid valve to place the cylinder piston in the
position which you wish to interrogate.
2. Shift the sensor along the cylinder axis until it switches, switching status display
(LED) is on.
3. Shift the sensor a few millimetres further in the same direction until it switches
back (LED is off).
4. Place the switch half the way between the switch-on and the switch-off position.
5. Tighten the clamping screw of the sensor with a hexagon screwdriver A/F 1.3.
6. Start a test run to check if the sensor switches at the correct point
(advance/retract cylinder piston).
