2 Working cycle (FP R-F1 ) The switch is fixed to the machine body (A), while the stainless steel actuator is fastened to the guard (B). Once installed, the switch will firmly lock the actuator. In order to remove the actuator, the knob (C) has to be rotated. On the first turns the electrical contacts will positively open, then, after about 0 seconds (or seconds depending on the knob version), the actuator will be released. In order to close the guard, the knob must be rotated in the opposite direction. This switch doesn t need power supply or timer and can be easily installed on old machines without important changes in their electrical circuit. The knob (C) may be supplied in a short (standard) or in a long version.

4 Example of working cycle steps with FD R-F1 These switches are used on machines where the hazardous conditions remain for a while, even after the machine has been switched off, for example because of mechanical inertia of the pulleys, saw disks, mills. This switch has its ideal application where the guard is not open frequently and the installation of a switch with solenoid would be too expensive. 1 1A TURNS Step 1 s or 0 s Step Step OPENING OF THE GUARD Step When the actuator is removed from the switch, the knob cannot be rotated back to the starting position. 1B A B C D Machine working Machine slowing down E Actuator locked Actuator locked Actuator unlocked Actuator extracted START CLOSING OF THE GUARD A Rotating heads and knobs The head can be quickly rotated on each of the sides of the switch by unfastening the two fixing screws. The mechanical delay device can be rotated in 90 steps as well. This enables the switch to assume different configurations. Actuator regulation zone 0,... mm This switch has a wide backlash of the actuator into the head (, mm) for an easier installation. With closed door, check that the actuator doesn t knock straight against the head of the switch; it must be in the adjustment zone (0, mm). B C A B Limits of utilization Do not use where dust and dirt may penetrate in any way into the head and deposit there, in particular where metal dust, concrete or chemicals are spread. Do not use where explosive or inflammable gas is present.
