FLO-GARD 6301 DUAL CHANNEL VOLUMETRIC INFUSION PUMP SERVICE MANUAL 07-19-B1-729
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).
3.
Disconnect the tube misloading sensors (Figure 11-6 or Figure 11-11 ,
items 10 and 11) from the connector at rear top of the pump head
assembly by pulling their connector housings. Do not remove them by
pulling the film portion.
4.
Open the pump door.
5.
Remove two Phillips screws (Figure 11-7 or Figure 11-12 , item 16) that
secure the upstream occlusion sensor (Figure 11-7 or Figure 11-12 ,
item 9) to the pump head base plate.
6.
Pull and rotate the sensor 45° clockwise and carefully remove it from the
pump head base plate.
7.
Remove the mounting block for the latch pin by removing the
appropriate screw securing the mounting block as follows:
Q
Pump 1 (Left FSR): Figure 11-6 , item 15
Q
Pump 2 (Right FSR): Figure 11-11 , item 15
8.
Remove the tube misloading sensor 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 suc-
cessful 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 K
Ω
and 210 K
Ω
. 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.
CAUTION
Do not scratch the ribbon connectors located above the sensors. Scratches can
damage the connectors.
CAUTION
Do not damage the base plate or the surface of the other tube misloading sensor
with the tool. Do not reuse the removed tube misloading sensor.
