SOFTWARE
WATCHDOG
FAULT
****NO FLOW****
Weigher offset is
greater than
acceptable value after
confirming all weight
is removed (175)
(0.21 VDC).
CPU relay fails to
close during system
start-up test.
CPU relay fails to
open during system
start-up test.
CPU did not execute
required steps
resulting in watchdog
time-out.
Pump set speeds have
decremented to zero
due to low pressure
measurement by
DPM.
1. Check, repair, or replace all electrical connections
associated with the weigher.
2. Check weigher offset in Diagnostics and verify the
problem.
3. Replace weigher load cell and calibrate weigher in A/D
in Utilities.
4. 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. This is a normal message if pressure from the donor is
low and is possibly caused by a flow restriction.
2. Use Diagnostics to check the DPM calibration.
3. Replace DPM. Use Utilities to calibrate DPM and SPM
in A/D screen, and safety system screen for DPM only.
