The TTL signal must have 0 volts for a "LOW" logic state.
The signal going "HIGH" (+5V) will trigger a flash
discharge. The pulse width of the signal can be used to
control the flash duration. However, the effective flash
duration can never be made longer than the nominal flash
duration of the flash tube (depending on the flash tube
used, the pulse width is typically 20µs to 500µs). For
example: If a flash discharge of 200µs duration needs to
be generated, a signal pulse with a "High" state (+5V) and
200 µs duration must be applied to the TTL jack.
RS485 Interface
The flash unit can be remotely controlled by using the
interface RS 485. The interface can be programmed and
configured according to specifications and requirement of
the customer via USB connection

Error Messages
NO FLASH
In case a trigger attempt fails the Speed Max will register
it as a "NO FLASH" error. The small yellow display
6
will
show the word "NO", the large red display
2
(FLASH/s)
"FL", and the large red display
3
(ENERGY) "AS". The
letter "H" cannot be shown because of the limitation of the
display to 6 digits. Possible causes for the error
messages: flash tube or equipment failure.
NO LOAD
If a problem during the charging process arises and the
power capacitors fail to reach their working voltage level
within 5 seconds, the charging attempt will be aborted.
This error will be displayed as "NO LOAD".
Please turn the flash unit off if an error message appears.
Wait 5 minutes, and then turn the unit back on. Should the
error message still appear, send the unit to Hensel-Visit
customer service or an authorized Hensel service station.
