Pulse
When 5V (TTL) has been applied to PIN 8,
FLD-nano sends one pulse (400V by
default) to trigger transformer. If flashlamp
is triggered successfully, a flash occurs.
In manual mode PINs 7 and 8 can be inter-
connected with a jumper for autorun mode.

Fault
When an internal fault of FLD-nano occurs,
the driver stops the operations and sets
PIN 10 to 5V (TTL) to indicate the failure.
To start the operations again, the cause of
the failure should be eliminated and after
then, FLD-nano should be disabled and
enabled again using PIN 5.
FLD-nano sets Fault state in the next cases:
• Overheating
