2.6.4 Magazine Slot Sensor Adjustment SIPLACE JTF-M
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.

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.

2.6.5 Checking Pawl Movement (SIPLACE JTF-S)
Checking Pawl Movement (SIPLACE JTF-S)
Both the short pawls and long pawls are located in the tower area of the feeder, near the level of the
conveyor (see figure "Bottom Plate and Mounting Screws"). If the pawls do not move freely, the motion
of the trays may become unreliable.
To test a short pawl, move each one with your fi nger. Each short pawl should move easily.
To test a long pawl, push the long pawl to one side.
Check to see that the long pawl can move freely in the up-and-down direction.
Push the long pawl to the other side, and test again.
If the pawls are sticking, do not lubricate them! The lubrication will cause the pawls to stick, and increase
the problem. Instead, disassemble the mechanism and clean the parts using alcohol.

2.6.6 Lift Cylinder Shock Absorber Adjustment SIPLACE JTF-S
Lift Cylinder Shock Absorber Adjustment SIPLACE JTF-S
The lift cylinder shock absorbers are designed to slow the rod less cylinder body at the end of its stroke
(see figure "Slip clutch elevator"). The shock absorber is not designed to be used as a stop. The rod less
cylinder body stop point is determined by the pawl lift rod stopping at its end of travel.
The following procedure outlines how to verify the shock absorbers are correctly adjusted, and how to
adjust if necessary.
Remove the cover on the lift mechanism (see figure "Alignment Pins").
Disconnect power to the feeder (leave the air pressure connected).
Manually fi re the lift cylinder down and measure the gap between the lift cylinder body and the shock
absorber (see figure "Incorrect-Elevator Bar is Not Level" to locate the lift cylinder manual activation
solenoid valves).
⇨ The gap should be approx. 3/32." (see figure Incorrect – Elevator Bars at same Level"). The body of
the shock absorber must not contact the body of the lift cylinder.
Manually fi re the lift cylinder up and observe the gap between the lift cylinder body and the shock
absorber on the other end of the stroke. The gap should be approx. 3/32."
If adjustment is required, loosen the lock nut on the shock absorber and turn the shock absorber until
the proper gap is reached.
Tighten the lock nut.
Manually fi re the lift cylinder in the opposite direction then back again to verify proper adjustment.
Attach the lift mechanism cover.
