8 Disassembly/Reassembly
8-16 FLO-GARD 6201 VOLUMETRIC INFUSION PUMP SERVICE MANUAL 07-19-B1-688
8. Remove the tube misloading sensors from the pump base plate with a
razor blade or similar tool.
Note: All adhesive residues must be removed from the surface to ensure the
successful attachment of FSRs.
9. Completely remove any adhesive residue from the base plate and clean
the surface with an alcohol-soaked cloth.
10. Using a digital multimeter, check that the resistance of the new tube
misloading sensor at no load is between 140 KΩ and 210 KΩ . If not, do
not use it.
11. Carefully insert the FSR flex cable through the opening for the upstream
occlusion sensor to avoid damage to the electrical traces on the FSR flex
cable. Loosely attach a new tube misloading sensor to the pump base
plate. Ensure that it fits within its recess and does not override the pump
head area. Do not attach the sensor firmly to the pump base plate yet.
12. Check that the resistance of the tube misloading sensor at no load is
within 140 KΩ and 210 KΩ .
Q If not, repeat steps 10 through 12.
Q If so, peel the backing off the adhesive, press the tube misloading
sensor firmly, and ensure that it is securely attached to the pump base
plate with no gaps.
13. Connect both sensors to the connectors at top rear of the pump base plate
through the hole for the upstream occlusion sensor. (See Figure 11-6 ).
14. Replace the upstream occlusion sensor to the pump base plate. Take care
not to damage the FSR flex cable while inserting the upstream occlusion
sensor housing. Calibrate in accordance with “DC Line Voltage
Calibration” on page 9-1 and “Upstream Occlusion Sensor Calibration”
on page 9-10.
15. Install the mounting block for the latch pin (Figure 11-6 , item 1) if it
was removed. Tightening torque is 6 kgf-cm (5.2 in-lb).
16. Reassemble the case halves.
17. Perform the Operational Checkout procedures in Chapter 10,
“Operational Checkout”.
Replacement of Pump Motor
1. Remove pump door cover in accordance with “Replacement of Pump
Head Door Cover” on page 8-9.
2. Separate the front and rear housings (“Separation of Front and Rear
Housings” on page 8-5).
