(2) For hand driver type (reed switch)
Such a contact is used for the screw feeding signal that turns ON during screw tightening. The screw
feeding starts in a specific time (Pa.82) after this contact turns OFF
→
ON
→
OFF. The screw feeding
solenoid valve and the track driving vibrator (to be more precise, Pa.41 + Pa.87 for the track driving
vibrator) continue operations for a preset time (Pa.41).

Screw taking-out
6.1.4.1. For screw taking-out type
(1) In the case of the FF503H of screw taking-out type, the presence or absence of screws in the taking-out
position is always monitored with the escapement unit photoelectric sensor.
↓
(2) When the operation enable input signal is output (ON) from the external control equipment to the
FF503H with no screws existing in the taking-out position, the escapement unit operates to provide
screws to the taking-out position.
↓
(3) When the preparation for screw taking-out is completed in the taking-out position, the FF503H outputs
(ON) the taking-out enable output signal to the external control equipment.
↓
(4) The external control equipment receives this taking-out enable output signal and turns OFF the
operation enable input signal to prevent the escapement unit of the FF503H from operating (interlock).
Then, take out the screws with the external equipment.
↓
(5) When the screws have been taken out, because there are no screws in the taking-out position, repeat
steps (2), (3) and (4) after making sure that the external equipment is out of the interference range.
