Indicated valve
position switch
indicates that valve is
in incorrect position.
The machine senses
that the jumper used
to gain access to the
extended
configuration
parameters has been
left in the machine.
Centrifuge encoder
signals indicate that
spindle speed is 300
rpm greater than set
speed.
1. Use the valve test in Diagnostics to manually transition
valves and monitor the valve and switch response.
2. Swap valve connections at top deck distribution card to
isolate problem to valve or circuit.
3. If valve does not move, check, repair or replace all
connections associated with the appropriate valve drive
circuit.
4. Replace valve, driver card, or processor card. Using
Utilities, calibrate all the components under A/D,
centrifuge, safety system, and configure the language.
Reset protocol parameters (MODIFY key), if parameters
were different from default values.
5. If valve does move but is not recognized, check, repair,
or replace all connections associated with the
appropriate valve position switch or replace the valve.
6. Replace driver or processor card. Using Utilities,
calibrate all the components under A/D, centrifuge,
safety system, and configure the language. Reset
protocol parameters (MODIFY key), if parameters were
different from default values.
1. Remove the extended configuration jumper from J104
on the processor Board.
2. Replace processor card. Using Utilities, calibrate all the
components under A/D, centrifuge, safety system and
configuration. Reset protocol parameters (MODIFY
key) if parameters were different from the default
values.
1. Using Utilities, display the centrifuge screen under
Diagnostics. Install bowl in centrifuge. Start centrifuge
and measure actual speed vs various set speeds. If
speeds are wrong, use calibration to calibrate centrifuge
speed.
2. If speed is wrong by a gross amount, set the centrifuge
set speed to 3000 rpm and measure the centrifuge
c signal at P401 pin 18A (pin 17) on the
backplane card. Signal should be 6.1 VDC. If
signal is wrong, replace the driver card.
3. Replace processor card. Using Utilities, calibrate all the
components under A/D, centrifuge, safety system, and
configure the language. Reset protocol parameters
(MODIFY key), if parameters were different from
default values.
4. If c signal is OK, replace either the centrifuge
controller card or the centrifuge assembly.
