USING THE TROUBLESHOOTING GUIDE
A. ALWAYS turn the machine OFF before replacing a circuit board or unplugging ribbon cables.
B. Observe Electrostatic Discharge (ESD) Precautions when working inside the card cage!
C. It is assumed the troubleshooter is certified and has working knowledge of the machine.
D. It is assumed the troubleshooter knows how to use a multimeter (Volts DC / Volts AC / Resistance).
E. DO NOT calibrate or swap parts unless instructed.
NEVER swap parts between malfunctioning
machines!
Parts should be tested (known good) in another machine before swapping them in.
F. Calibration(s) may be required after replacing a component. Refer to
(page 668).
(page 12) before returning the machine to clinical service.
H. Be CAREFUL to maintain your current location as you proceed AND read each procedure before
performing it.
Pay attention to ‘CAUTIONS’ and ‘NOTES’
!
I.
Troubleshooting procedures are arranged as a ‘flow chart’. ENSURE you go to the CORRECT
procedure number as prompted. You CANNOT necessarily read down the page as sometimes
procedures on that page are SKIPPED.
J. Sometimes procedures ‘call’ another procedure in a different Section.
NOTE
the current procedure and
page number BEFORE proceeding to the ‘called’ procedure!
K. If multiple ‘possibilities’ are suggested (example: TWO (2) possible bad components:
1)
Bad Actuator-
Test Board;
2)
Bad Functional Board), swap the listed components, with known good, one at a time,
starting with the first component in the list. In between test the machine to see the new part fixes the
problem. If NOT continue through the list until the machine is fixed.
L. Hydraulic components can be isolated via the DISTRIBUTION BOARD. Referring to
(page 4):
There are three (3) Distribution Board sections:
1)
Sensors;
2)
Pumps;
3)
Valves
Electronic hydraulic components each have labeled connector positions as referenced in the 2008
Flow Diagram. Labels are printed above or below each position. For example, Float Switch #5 is
labeled “X5, FLOAT-SW”, temperature sensor NTC #2 is labeled “X2, CON-NTC”, etc.
From left-to-right, positions start at #2 [example: NTC #2, labeled “X2, CON-NTC”].
There is no
position #1!
Post Dialyzer Temperature Sensor #44 plugs into position #14; Valve #41 plugs
into position #27
The plastic connector caps should be labeled to match the position
There are several VACANT positions! When removing a connector
NOTE
its position and label.
Be CAREFUL to return all connectors to their correct positions!
Turn the machine off BEFORE unplugging OR plugging RIBBON cables. These include the
SENSORS, ACTUATOR, Acid (#16) and Bicarbonate (#17) Pumps, Blood Leak Sensor (#8),
Heparin Pump (#18) and the Blood Pressure Module
