6. Mount the force sensor on the driving block holder using a TF HC M4x10 screw with weak lactate.
Important: avoid all contact between the force sensor and its holder.
7. Mount the contact plate on the force sensor using a TF M4x10 screw with weak loctite.
Important: Before calibrating the force sensor, adjust the threshold voltage (0.6V + 0.05V) using an os-
cilloscope between pin 1 (earth) of J09 and pin 4 of J09 (square pulse).
Important: The device must be in the calibration mode (EtA9), obtained by simultaneously pressing the
SILENCE ALARM key, the bolus key and the "ON" key.
8. Check that the amplitude of the square pulse increases when a manual force is exerted on the force
sensor. When the force is removed from the sensor, the signal must return to the initial position.
Otherwise, check that the sensor is correctly mounted (sensor/holder friction).
4.2.1. Mounting the potentiometer
1. Disassemble the reducer flask end shield.
2. Mount the potentiometer on the flask (take the nut on a thread).
3. Position the flask in equipment and lock it in place using the knurled screw.
4. Position the potentiometer in the equipment and bring it up against the end shield.
5. Tighten the potentiometer.
6. Extract the flask from equipment .
7. Mount the pinion on the potentiometer (match up the indexing half flat).
q
The pinion large diameter must be flattened against the potentiometer.
8. With the potentiometer facing you, turn the pinion in an anticlockwise direction until it blocks, then
turn it 1/4 of a turn in the opposite direction.
9. Mount the moving mechanical assembly on the reducer frame.
10. Insert the flask on the guides and rack.
q
Check the position of the input bearing which must be on the driving block side.
q
Important: Take care not to damage the flexible circuit when mounting (folding).
11. Secure the end shield using the three M3x3 TC screws.
12. Secure the input bearing using the two M3x3 TC screws.
4.2.2. Wiring the potentiometer
1. Weld the 3 wires perpendicular to the lugs by placing them in the holes.
Important: Do not fold the potentiometer lugs
2. Mount the pinion and the potentiometer matching the indexing half flat with the
small diameter of the pinion towards the potentiometer.
3. Mount the pinion hocking diameter 4 Truarc ring using a pair of flat mose fliers bearing down on the
potentiometer shaft half flat.
4. With the pinion facing you, turn the potentiometer anticlockwise until it blocks, then turn it 1/4 of a
turn in the opposite direction.
5. Disengage the moving assembly and slide it until it blocks against the reduction gear flange.
