Code
Lamp reference voltage out of range (1459 – 1917)
2901
See self-test Voltage Reference "Lamp".
This tests the voltage across a sense resistor in series of the lamp. It is monitoring the current
through the lamp. This test is performed when the instrument is first turned on and then tested
periodically during background functions.
Probable Causes:
• The lamp is weak or defective—change the lamp (BioTek PN 7080500).
• The sense resistor is damaged on the 7090402 PCB.
• The regulator mounted on the 7090402 PCB is defective.
• Verify the lamp is actually on or off. Perform a self-test. This error can give false errors. If
the lamp is on, disregard this error.
• Reference Field Change Notice L0045.
24V reference voltage out of range (1769 – 2162)
2902
See self-test Voltage Reference "24V"
This tests the voltage across a sense resistor in a series of the 24 volts; it is monitoring the current.
This test is performed during self-test.
Probable Causes:
• The motor power supply PCB is defective.
• The sense resistor is damaged on the motor power supply PCB.
40-Volt Motor reference voltage out of range (2027 – 2069)
2903
See self-test Voltage Reference "Mtr"
This tests the voltage across a sense resistor in series of the 40 volts; it is monitoring the current.
This test is performed during self-test.
Probable Causes:
• The motor power supply PCB is defective.
• The sense resistor is damaged on the motor power supply PCB.
2904 3.5V Flash Power Supply reference voltage is out of range (1399 – 1453)
See self-test Voltage Reference "Min"
This tests the voltage across a sense resistor in series of the 3.5 volts; it is monitoring the current.
This test is performed during self-test.
Probable Causes:
• The motor power supply PCB is defective.
• The sense resistor is damaged on the motor power supply PCB.
2905 4.25V Flash Power Supply reference voltage is out of range (1699 – 1772)
See self-test Voltage Reference "Low"
This tests the voltage across a sense resistor in series of the 4.25 volts; it is monitoring the current.
This test is performed during self-test.
Probable Causes:
• The motor power supply PCB is defective.
• The sense resistor is damaged on the motor power supply PCB.
5.25V Flash Power Supply reference voltage is out of range (2110 – 2211)
2906
See self-test Voltage Reference "High"
This tests the voltage across a sense resistor in series of the 5.25 volts; it is monitoring the current.
This test is performed during self-test.
Probable Causes:
• The motor power supply PCB is defective.
• The sense resistor is damaged on the motor power supply PCB.
