Adjustments

Brush adjustment.
The eject brush places the screws that flows along the track and throws the ones in the wrong position in the storage.

Procedure:
To adjust the eject brush height, loosen the screws in the picture below, raise or lower the brush to the height of the head of your screw. If the brush has been set too high, screws in the wrong position could pass and stop the passage. If too low, the brush could get stuck.
Bit guide & track cover adjustment.
To pick the screw up correctly, the bit guide should be centered on the screw head (see picture below). It’s also possible to adjust it right/left and forward/backward. It should be also adjusted the height of the track cover in such a way as to pass only the screws in the correct position. Procedure:
Remove the front panel by unscrewing the 4 screws as in the picture below and by slipping off the power button.
To adjust the bit guide right/left, loosen A screws and turn E screw: clockwise to move the bit guide to the right, and counterclockwise to move it to the left. Once you have found the right spot, tighten A screws.
To move it forward/backward, loosen D screws, find the correct position and fasten it again. To adjust the height of the block track coverbit guide, loosen B and C screws and turn the screw clockwise to lower, and counterclockwise to raise it. Once you have found the right spot tighten B screws.
To adjust the advancement of the track cover using F screws to cover up to the penultimate screw (see picture here below).
Speed adjustment.
To adjust the vibration speed and the speed of movement of the brush/ loading wheel depends on the use and on the type of screw.
G trimmer adjusts the vibration speed, while H trimmer adjusts simultaneously the speed of the brush and of the wheel of charge. For both the trimmer, if turned clockwise, the speed increases, anticlockwise it decreases.After the adjustments, reassemble the NFK. Make sure that all screws are tightened properly.
Track adjustment.
Thanks to the kit of spacers (from 1.3 to 5.3 mm of thickness ) supplied with the NFK, it is possible to adjust the NFK screws from M1 to M5. Procedure.
Remove the front panel as previously explained (see Bit guide regulation).
To remove the track, it’s first necessary to enlarge the 2 gate lock screws. Loosen the i and L screws, then M and N screws up to a sufficient width to extract the track.Loosen O screw and then extract the track.

Options

Signal on the rear panel.
On the rear panel of the NFK/RS, near the power supply connector, there is a jack power connector (used with the supplied connector).

The jack power connector will give a relay contact (10A 250VAC or 30VDC): open contact is case of missing screw and closed contact in case of screw loaded.

Troubleshooting.

Connect the AC/DC adapter to the power source
The power switch is set on OFF| Set on ON the power switch
NFK is set on ON but screws don’t exit| Screws not suitable| Check the screw size and properly calibrate the NFK
Track cover adjusted too low| Adjust the track cover again
Exit speed too low| Increase the speed
Foreign material inside the storage| Clean the storage and the track
Sensors not aligned| Check sensor alignment
Screws stuck in the track| Brush, track, cover track in wrong position| Adjust them again

I/O CONNECTIONS

On the back connector, it’s possible to get the signal of screw present. The contact is “normally” open (screw not present) and closed (screw present).

As you can see from the picture below, on the back panel of the NFK Nxx RS, there is a 3.5 mm female jack connector in which it is possible to bring out the clean contact of an internal relay (10A 250VAC or 30VDC).
Using a stereo connector from the TIP and RING contacts it is possible to obtain the screw presence contact.
Since the SLEEVE pin is directly connected to the chassis, if you want to ground the NFK Nxx RS, it is necessary to connect the SLEEVE pin directly to ground as shown below.
ATTENTION: Never connect the SLEEVE pin to the power supply otherwise also the NFK chassis will be under tension, creating possible short circuits with robots or other device that will come into contact with the chassis itself.

NFK UNI Troubleshooting Guide
If the NFK UNI presents issues with not detecting when a screw is present/ not present at the front of the rail you can make the following adjustments after removing the front cover.
Adjusting the rail: Sometimes during shipping or initial set up the rail can move from the original pre-set position. Often the rail is too far out towards the front of the presenter and simply needs to be pushed back a small amount in order for it to properly line up with the sensors.
Rail:

To adjust the rail, you want to loosen this screw: Once properly positioned fasten the screw again and turn the presenter on. If the issue continues you may need to adjust the sensors found on either side of the rail’s front section. The sensors should be in matching positions on both side of the rail and aligned with the front portion of the rail where a screw rests after being fed. After this is complete turn the presenter back on and check to make sure the adjustments work
