Table 4-9: General episodic logging
Episodic Line Definition
Blink Test T1 : 1; Pass Value :
VALVE_LED_TEST_NOMINAL(1) The safety system turns off the +5 V LED power at startup and every
60 seconds after to check the position measurements in the valve
system, the cassette system, and the door lock assembly. The
position information is recorded in the dlog file in hex format and
needs to be converted to binary to find the location of the sensor
indicating the problem. During this test, each system must return an
unknown position with all the bits returning a binary “1.” If a binary
“0” is returned during the test, that sensor is suspected to have
failed, is unplugged, or has an intermittent connection. See Episodic
error logging to decode the failures of this test.
RBCValve T1 : 14; Pass Values :
ALL_VALVE_POSITIONS_VERIFIED(15) or
ALL_VALVE_POSITIONS_VERIFIED_XCEPT_
UNKNOWN(14) The measured valve positions: all the valves have cycled through all
possible positions.
PseudoValve T1 : 15; Pass Values :
ALL_VALVE_POSITIONS_VERIFIED(15) or
ALL_VALVE_POSITIONS_VERIFIED_XCEPT_
UNKNOWN(14) The virtual valve positions in the software: all the valves have cycled
through all possible positions.
Inlet Container FlowIO; 1 ValveIO: 1 (also
Return and AC) Platelet Container FlowIO: 2
ValveIO: 1 VolLimit: –1560.00000 (also
Plasma and RBC) Indicates the flow direction for each valve in relation to the bag.
• FlowIO: [0 = unknown, 1 = into the cassette, 2 = into the bag, 3 =
recirculate]
• ValveIO: [0 = unknown, 1 = collect, 2 = open, 3 = return]
• VolLimit: maximum volume allowed in the bag (mL)
