Table 4-10: Episodic error logging
Episodic Error Line Definition
Blink fail: status=0x####
This error indicates a valve LED blink test failure. The #### is a four-
digit hex value that needs to be converted to a binary value to be able to
determine which sensor is reporting a “0.”
To convert hex to binary, complete the following steps:
1. Open the Windows 7 calculator in Programmer view.
2. Click
Hex
and enter the hex code; for example 17ff.
3. Click Bin to convert the hex to binary, which for the example above
is 1 0111 1111 1111.
4. Count the bits from right to left starting with 0, then 1, then 2 and so
on. The bit on the far left is number 12 and the bit on the far right is
0.
In the example above, the 11th bit is 0, which indicates a problem
with the door lock solenoid position sensor.
The position of a “0” bit indicates which sensor is having the problem.
Multiple “0” bits can be indicated. The meaning of a “0” bit in each
position is given in the following list:
“0” Bit Position Sensor Problem
0 Plasma valve return
1 Plasma valve collect
2 Plasma valve open
3 RBC valve return
4 RBC valve collect
5 RBC valve open
6 Cassette loaded
7 Cassette unloaded
8 Platelet valve return
9 Platelet valve collect
10 Platelet valve open
11 Door lock solenoid position
12 Door position (optical)
If you have a “blink fail: status=0x1800,” which is binary code
1 1000 0000 0000, this problem could be that the valve harness is
unplugged.
If you have a “blink fail: status=0x1f3f,” which is binary code
1 1111 0011 1111, this problem could be that the cassette loaded and
cassette unloaded sensors are unplugged.
