DPM low pressure
load test produced a
value that is out of
the range of 1265 -
1620.
DPM low pressure
load test produced a
value that was ± 7%
from calibrated
value.
1. Replace 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. Replace driver card.

1. Using Diagnostics in Utilities, load the DPM for low
pressure and measure the DPM signal at P502 pin 1 of
the backplane card. Acceptable range for low reading is
1.54 - 1.98 VDC (1265 - 1620). 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
low pressure digital reading is between (1265 - 1620). If
digital reading is out of range or grossly fluctuating,
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.
