Feed Pusher Pneumatic Adjustment
The feed pusher assembly moves the tray from a stationary position in the magazine onto the moving
conveyor (see figure Tray feed pusher assembly (view from top)). A pneumatic fl ow control valve deter-
mines the speed of the "push" function. The "pusher return to home" function is controlled by spring ten-
sion. The following procedure outlines the feed pusher adjustments.
The feed pusher pneumatic fl ow control is located under the bottom plate (see figure "Removing the Bot-
tom Plate").
► Remove the front cover and then bottom plate to access the fl ow control valve (see figure "Feed
pusher flow control valve").
► To adjust the feed pusher speed; unlock the adjustment screw by loosening the locking nut (see fig-
ure "Feed pusher flow control valve").
► To increase the feed pusher speed, turn the adjustment screw in a counter clockwise direction.
► To decrease the feed pusher speed, turn the adjustment screw in a clockwise direction.
► Adjust pusher speed so trays reliably move onto conveyor without dislodging components.
► When adjustment is completed, tighten the locking nut and reattach bottom plate.

Magazine Slot Sensor Adjustment SIPLACE JTF-M
The magazine slot sensor is adjustable in height (see figure "Magazine Slot Sensor"). Readjustment may
be required if the trays hit the magazine while returning from the conveyor or if the trays are not grabbed
by the conveyor belts after feed them from the magazine:
The magazine slot sensor is located here:
► Bring the empty magazine up to first slot (the feeder will do so automatically after power on).
► Hit the stop button on the front panel.
► Put an empty tray onto the conveyor and try to slide it into the magazine.
► Verify that it does not hit the upper magazine or the lower magazine slot.
► If it does, release the two mounting screws of the magazine slot sensor sender and receiver but
measure the gap between the sensor top and side plate before with a caliper.
► Test the new position by cycling multiple trays in the cassette.
► Make sure the sensor does not miss any magazine slots.
► First run empty trays and if ok use trays load with parts.
► Make sure the parts do not jump out of their pockets while cycling.
Magazine Slot Sensor
1. Magazine Slot Sensor Receiver
2. Magazine Slot Sensor Sender
Measure slot sensor gap
► Set a new measurement which may work on the cal-
iper and adjust the sensor receiver and sender to the
new setting (see figure "Measure slot sensor gap").
The distance measured may be different for sender and
receiver.
