Initiate Diagnostic Mode
The circuit board includes buttons which initiate a diagnostic mode. While diagnostic mode is initiated, the
functions for each compartment location can be tested. When the circuit board is in diagnostic mode, the board
will not recognize inputs from the BloodTrack
®
touchscreen/computer.

Press the “1-STEP” button to select Position 1.
►
Position 1 corresponds to the compartment location in column “A”, when viewed from the front of the
Compartmental Access Refrigerator™.
►
With Position 1 selected, the solenoid powers on, and the red and blue LEDs turn on briefly.
►
If the optical sensor for Position 1 is interrupted, the red LED will turn off for the duration the sensor
is interrupted.
3
Wait until the red and blue LEDs turn off, then press the “1-STEP” button again to select Position 2.
►
Position 2 corresponds to the compartment location in column “B”, when viewed from the front of the
Compartmental Access Refrigerator ™.
►
With Position 2 selected, the solenoid powers on, and the red and blue LEDs turn on briefly.
►
If the optical sensor for Position 2 is interrupted, the red LED will turn off for the duration that the sensor
is interrupted.
4
Wait until the red and blue LEDs turn off, then press the “1-STEP” button again to select Position 3.
►
Position 3 corresponds to the compartment location in column “C”, when viewed from the front of the
Compartmental Access Refrigerator™.
►
With Position 3 selected, the solenoid powers on, and the red and blue LEDs turn on briefly.
►
If the optical sensor for Position 3 is interrupted, the red LED will turn off for the duration that the sensor
is interrupted.
5
Wait until the red and blue LEDs turn off, then press the “1-STEP” button again to select Position 4.
►
Position 4 corresponds to the compartment location in column “D”, when viewed from the front of the
Compartmental Access Refrigerator™.
►
With Position 4 selected, the solenoid powers on, and the red and blue LEDs turn on briefly.
►
If the optical sensor for Position 4 is interrupted, the red LED will turn off for the duration that the sensor is
interrupted.
6
After Position 4 check ends, IRACS will exit from diagnostic mode and return the circuit board to normal operation.
NOTE
With diagnostic mode initiated, if 30 seconds elapse without any actions (button presses), the circuit board will automatically exit
diagnostic mode and return to normal operation.
