8.0 FAULT DETECTION
The strobe continuously monitors the high voltage, the temperature and the cooling fan
for fault conditions. In the event that a fault is detected the display will indicate FAULt
on the top line of the display and the type of fault on the line below that. In the event of
a voltage or temperature fault the strobe will stop
fl
ashing and the fault is continuously
displayed. If the fault should correct itself, the strobe will begin
fl
ashing again and the
display will alternate between the regular display and the fault display. The event has to
be cleared by the user using the ESCAPE button or POWER SWITCH.
In the event of a FAN fault, this will be indicated on the display and the strobe will
continue
fl
ashing until a more serious fault occurs. A FAN fault can be caused by a
clogged
fi
lter – see MAINTENANCE below.
9.0 MAINTENANCE
Ensure the unit is turned OFF and AC power is disconnected before
attempting any maintenance.
The illumiNova™ has no user serviceable
parts inside the enclosure. The only item
that requires maintenance is the cooling
fan
fi
lter which is accessible on the right
end of the unit looking at the rear of the
enclosure. The
fi
lter will need cleaning
periodically depending on the environ-
ment.
Removal requires the use of a Phillips head
screwdriver.
Undo the four screws retaining the fan guard (these are the inner screws – A) and
remove from unit. This exposes the fan
fi
lter as shown right. Remove the foam
fi
lter.
It can be cleaned by blowing with compressed air or washing gently with plain water.
Once cleaned, replace the
fi
lter and, the guard and secure with the screws (A).
Note: A fan guard/
fi
lter replacement kit is available as Monarch part number

6.4 Time Pulse Duration
This method adjusts the
fl
ash pulse width to a
fi
xed number of microseconds. Here
the user sets the
fl
ash pulse width in microseconds not degrees. As the
fl
ash rate
increases the pulse width stays the same and the image will get brighter and more
blurred as the
fl
ash width remains constant. The degree of rotation visible changes to
keep the pulse width of the
fl
ash constant. The range of width is 1 to 150 microsec-
onds. In the event that the setting exceeds the maximum settings when changing
fl
ash rate, the strobe will limit the value and the
μ
sec icon will blink on the display.
7.0 STROBE DELAY
The IllumiNova™ has multiple delay e
ff
ects that can be used to inspect moving
machinery in di
ff
erent ways. These delay e
ff
ects are mode speci
fi
c.
7.1 Internal Phase/Time Delay (JOG)
In the Internal Mode the user can shift the apparent position of the
fl
ash by jogging.
This can be done as a Phase Delay in degrees (-360.0° to +360.0°) or Time Delay in
milliseconds (-50.000 to +50.000 msec). Once the
fl
ash rate has been adjusted to give
a stopped motion image, the PHASE or TIME arrow icons on the touch-screen can
be used to increase or decrease the position of the image with respect to its original
position by the amount set in the JOG menu option (see section 5.4).
7.2 External
Delay
There are three External Delay options: Phase Delay, Time Delay and Virtual RPM
(Auto). These modes are only active if an external trigger source is connected. Note:
The NONE menu setting turns the External Delay mode o
ff
(see section 5.4).
7.2.1
External Phase Delay
In the External Phase Delay Mode the
fl
ash is delayed from the external trigger by
the number of degrees set in the DELAY PHASE menu (-360.0° to +360.0°). One
revolution is 360°. The display will show the PHASE icon to indicate the delay mode.
7.2.2
External Time Delay
In the External Time Delay Mode the
fl
ash is delayed from the external trigger by
the time in milliseconds (msec) set in the DELAY TIME menu (-50.000 to +50.000
msec). The TIME Delay is absolute and remains constant irrespective of the speed
of the target. The display will show the TIME icon to indicate the Delay Mode.
7.2.3
External Virtual RPM (AUTO)
In the External Virtual RPM (VRPM or Auto) Mode the
fl
ash is automatically delayed
in increasing or decreasing amounts after the external trigger pulse so that the image
appears to rotate at a slow speed (Virtual RPM) as set in the VRPM menu (-60 to 60
RPM). This gives a “slow-motion” e
ff
ect and enables the target to be examined as it
moves through a complete cycle or revolution. The display will show the AUTO icon
to indicate the Delay Mode with the virtual speed in RPM on the top line.
