7-14 FLO-GARD 6201 VOLUMETRIC INFUSION PUMP SERVICE MANUAL 07-19-B1-688
12 Upstream occlusion was detected
in Revolution Counter Interrupt.
See Failure Identification Code 4.
20 Malfunction in Door Open
detection circuitry: P54 of the
Master CPU remains low.
Check that magnet in pump door
latch is present.
Replace pump door latch when
magnet is missing.
Repair or replace CPU board.
21 Malfunction in frequency
converter circuitry for occlusion
detection: P20 of master CPU
remains high or low.
Check connectors CN851 and
CNBUS1/CNBUS2 for proper
connection and continuity.
Repair or replace connectors as
necessary.
Replace CPU board.
Replace Sensor board.
22 Malfunction in frequency
converter circuitry for occlusion
detection: P20 of master CPU
remains high or low.
See Failure Identification Code
21.
Verify low resistance (<30 Ω)
between CN851-1 and CN851-2
(upstream occlusion coil) and
CN851-3 and CN851-2
(downstream occlusion coil)
See Corrective Action for Failure
Identification Code 21
Replace the failed coil as indicated
by the high resistance reading.
Also, replace the core and actuator
of the applicable occlusion sensor
and recalibrate.
23 P50 (IRQ interrupt port) remains
high.
Check U101 pin 10 for a high
(+5 VDC) signal.
Replace CPU board.
24 UP and DOWN occlusion values
agree.
Check connector CNBUS1/
CNBUS2 for proper connection
and continuity.
Repair or replace CNBUS1/
CNBUS2 if necessary.
Replace CPU board.
Replace Sensor board.
25 Failure in occlusion circuit None Replace CPU board.
27 Malfunction in slide clamp
detection circuit.
Check battery voltage in
accordance with “Automatic Test
Mode 1: Calibration Mode 1” on
page 9-14.
Check connector CN803 for
proper connection.
Clean contacts.
Charge or replace the battery.
Repair CN803 if necessary.
Replace safety/slide clamp
assembly.
28 Two air sensor outputs (NORM
and MIN) cannot be selected.
Check connectors CN811 and
CNBUS1/CNBUS2 for proper
connection and continuity.
Repair or replace CN811 or
CNBUS1/CNBUS2 if necessary.
Replace CPU board.
Replace Sensor board.
29 Two occlusion sensors (UP and
DOWN) cannot be selected.
Check tightness of connectors
CN851 and CNBUS1/CNBUS2
for proper connection and
continuity.
Repair or replace CN851 or
CNBUS1/CNBUS2 if necessary.
Replace CPU board.
Replace Sensor board.
