1. Replace driver card.
2. Replace safety card.
1. Replace driver card.
2. Replace safety card.
1. Replace the safety card.
2. 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.
1. Using Diagnostics in Utilities, load the DPM for high
pressure and measure the DPM signal at P502 pin 1 of
the backplane card. Acceptable range for high reading is
3.98 - 4.98 VDC (3260 - 4080). If analog voltage
exceeds range, replace DPM.
2. 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.
1. Recalibrate the safety system in Utilities and verify that
high pressure digital reading is between (3260 - 4080). If
the digital reading is out of range, replace DPM.
2. 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.
1. Replace driver card.
2. Replace safety card.
