Solution/Suggestion
Verify that both the Flashlamp "ready" light and the Flashlamp "start" light on the Remote Box are
illuminated.
Verify that Internal sync is selected in the Remote Box Flashlamp menu.
Make sure the "interlock" light on the Remote Box is steadily on, but is not blinking.
After pressing the "Flashlamp Ready" button on the Remote Box, if the "ready" light does not
light, and is there a no visible flashlamp flash, the flashlamp may need to be replaced. See the
instructions for flashlamp replacement.
• Flashlamp is not enabled. Verify that both the "flashlamp ready" light and the "flashlamp start"
light on the Remote Box are illuminated.
• External trigger signal does not meet the specified requirements as shown in
Trigger Signal Requirements on page
If the flashlamp does not flash, it may be an indication that the lamp will not simmer or is difficult to
simmer. Check to see that the simmer indicator is illuminated when high voltage is enabled. If it is
not, either ionized or contaminated coolant, or a degraded flashlamp may be the cause. Coolant
resistivity must be within the range for proper operation. See
on page 72 for information on coolant properties. If coolant resistivity is less than the
recommended value, replace the coolant. If the lamp still does not simmer, follow the procedure
for Flashlamp Replacement on page
The PRF setting may be set for external mode and the external trigger is either not connected or is
not adequate to drive the 50Ω input. Set the PRF setting for internal PRF control.
If the ICE makes a squealing or hissing sound when the high voltage is enabled, and the simmer
LED is illuminated but the flashlamp does not flash, disable the high voltage immediately.
WARNING: A component inside the ICE may have failed and the high voltage charger is
attempting to charge into a short circuit. If the ICE is operated in this mode for longer than
a few seconds, additional electronics damage may occur.
