Setting the size sensor flag
1. Using the 3200 size sensor test gauges (see page A-5), fit the white 20 ml minimum
sensor gauge (
part number 0131-0170) into pump's cradle and observe whether (a)
or (b) occurs:
a. If the pump indicates that a 20 ml gauge is fitted, complete steps (2) to (5).
b. If no indications are given, complete steps (6) to (8).
2. Depending upon the type of pump being set-up, if either the 20ml LED is
illuminated, or the display shows 20 , rotate the grub screw counter-clockwise until
the corresponding LED/ display is extinguished or disappears.
3. Turn the grub screw slowly clockwise until the LED/ display illuminates or appears,
indicating that a 20 ml syringe is fitted.
4. At position X (see Figure A.3 Size Sensor Flag, general details), alternately press
and release the SSF several times and ensure that when the SSF returns to it's rest
position, it
always displays that a 20 ml syringe is present.
Note : It is acceptable that while the SSF is under force, the size of the syringe displayed
alters. However, it must always return to the original 20 ml size displayed when the force
is released.
5. If the pump does toggle between different syringe sizes, turn the grub screw very
slightly clockwise and complete step (4) again until the 20ml LED/ display is stable.
Procedures if (b) above occurs
6. Depending upon the type of pump being set-up, if the 20 ml LED is not illuminated,
or the display does not show 20 , rotate the grub screw slowly clockwise until the
LED/ display illuminates or appears indicating that a 20 ml syringe is fitted.
7. At position X (see Figure A.3 Size Sensor Flag, general details), alternately press
and release the SSF several times and ensure that when the SSF returns to it's rest
position, it
always displays that a 20 ml syringe is present.
Note : It is acceptable that while the SSF is under force, the size of the syringe displayed
alters. However, it must always return to the original 20ml size displayed when the force is
released.
8. If the pump does toggle between different syringe sizes, turn the grub screw
very
slightly clockwise and repeat step (7) until the 20 ml LED/ display is stable.
Apply a small amount of Loctite 414 to the anti-tampering grub screw cap and fit it.
When the grub screw in the SSF has been set, the remaining procedures required to
complete the size sensor testing may be completed. Press and release the SSF
each time a new gauge is placed in the pump's cradle.
