External Input Mode
The strobe is in the External Input Mode whenever there is a plug in
the input jack. When the strobe is in the External Input Mode,
EXT
will be displayed.
In the External Input Mode the user can’t make any flash rate adjustments.
The flash rate is a function of the input signal. This mode is used to
synchronize the flash to an external event (for example, from an optical
sensor) to stop or freeze motion. The flash will be triggered on the rising or
falling edge (menu selectable) of the external input pulse.

Tachometer Mode - External Input Required
When an external input is supplied to the unit and the strobe is put in
the Tachometer Mode, the unit will read the signal from the external
input (sensor) and display the reading on the LCD display without
flashing the lamp.
The strobe will not flash in the Tachometer
Mode.
To enter the Tachometer Mode:
1.
Press the
ALT FUNCTION
button and then the
TACH
button.
2.
The
TACH
icon will be displayed.
NOTE:
If the external input signal exceeds the maximum flash rate,
the strobe will go into the Tachometer Mode automatically.
To exit the Tachometer Mode:
1.
Press the
ALT FUNCTION
button and then the
TACH
button.
2.
The
TACH
icon will go away.

External Delay Modes (Phase Shifting)
There are three
External Delay Modes
:
Phase Delay
,
Time Delay
, and
Auto (Virtual RPM)
. In the
External Phase Delay Mode
the flash is
triggered 0.1 to 359.9 degrees after each external signal pulse. The knob
sets the amount of delay in degrees. In the
External Time Delay Mode
the flash is triggered 0.01 to 1000 milliseconds after each external signal
pulse. The knob sets the amount of delay in milliseconds. In the
Auto
(Virtual RPM) Mode
the flash is triggered by increasing amounts after
the external trigger pulse so that the image will appear to rotate at a given
(virtual) RPM or RPS. The knob sets this virtual RPM or RPS.
To enter one of the External Delay Modes:
1.
Ensure there is an external input plugged in (so the unit is in
External Input Mode).
2.
Press the
Phase Delay
button to cycle to the desired mode.
3.
Use knob to adjust delay/angle (phase, time or virtual RPM).
To exit the External Delay Mode:
1.
Press the
PHASE DELAY
button to cycle back to External only.
2.
The word
PHASE
or the
TIME
or
AUTO
icon will go away.
