i. Monitor the power supplies, the safety shutter, the control panel, the footswitch connection, the
delivery fiber connection and the BRH interlock.
j. Monitor the footswitch.
k. If the footswitch is released, end treatment and return to Ready state.
l. When the footswitch is released or a fault is detected during treatment, the sytem will do the follow-
ing:
• Stop firing the lamps (after the pulse set up or running has completed).
• Close the safety shutter.
• Enable the control panel monitoring.
• Go back to Ready or Error state if a fault is detected.
SYSTEM MONITORING:
1. Upon power up and self-test, the system will perform the following initializations:
a. Configure the digital I/O chips and set the outputs to their defaults.
b. Test various CPU features and stacks.
c. Set all analog outputs to their safe default state.
d. Test the data memory.
e. Initialize the data memory.
f. Check the nonvolatile memory. Calculate its checksum and compare with stored value. Failure
causes memory to be reinitialized to default values.
g. Check the ROM. Calculate the CRC and compare with stored value. If the test fails, the system will
set a permanent error and display the calculated CRC value.
h. Initialize serial communication with the display.
i. Display the Power-On Self-Test (POST) screen.
j. Display results of each self test with PASS or FAIL or fault that caused failure or abort.
k. Check the low voltage power supply voltages.
l. Check the DACs by readback on the ADC.
m. Test the safety shutter by moving it to both positions and reading its position sensors.
n. Test the low energy attenuator by moving it to both positions and reading its position sensors.
o. Test the footswitch EPLD.
p. Check and calibrate the fiber optic communication with the power supply.
q. Check the crowbar operation.
r. Verify that all flashlamps are working.
s. Calibrate all lasers.
t. Calibrate the low-energy attenuator at all wavelengths present in the model in use.
u. Test the Safety EPLD as described below.
