contacts.

To ensure positive breaking of the contacts, exceed the pre-travel by 1.5mm or

FD/ FP/ FL

Programmable head – lever operation models

All limit switches with lever operation in the FD/ FP/ FL ranges can be user-set to switch by clockwise rotation only, anti-

clockwise only or both. To change the operation, which is factory set to switch in both directions, the four screws securing

the turret head should be loosened, the head removed and the internal piston rotated through 90˚. The head should then be

replaced.

The models to which this applies are: 531; 532; 533; 535; 536; 538; 551; 552; 553.

Figure 1 shows the piston position for switching in both directions, figure 2 for clockwise only and figure 3 for anti-

clockwise only.
