MC 1500
Fault Possible causes and remedial action
8. Segment setting or
rotation mode not
functioning
• Has the LED unit to be set already been
selected? If necessary select using switch (1)
(also see Section 8.2 or 8.4)
9. Light does not
change when (M1)
to (M4) memory keys
activated
• Have the memory keys already been
programmed? If necessary save different
illumination conditions by pressing down the
M key together with one of (M1) to (M4) keys
10. The programmed
settings are deleted
when the MC 1500 is
switched off
• Default values are set when the MC 1500 is
switched on. Please save individual settings
in memory stations before switching
off controller.
11. Strobe mode:
Illumination not
pulsating
• Is strobe activated? Select required illumination
unit using (1) and activate strobe mode (9).
• Is strobe frequency too high, strobe intensity
too low or strobe pulse duration too long?
Optimize variables. If necessary set strobe
intensity individually for both LED units
(see Section 8.6).
12. Strobe mode:
no stationary image
• Is movement of the specimen periodic with a
constant frequency? Only then are stationary
images possible.
• Optimize strobe frequency (see Section 8.6).
13. Strobe mode:
Stationary image is
blurred or pale
• Please decrease strobe pulse duration.
If necessary increase strobe intensity individually
for each unit (see Section 8.6).
• Preferably activate strobe mode for both VisiLED
units. If that is not desirable reduce the
brightness of unit that shall not strobe to
required minimum.
• If necessary reduce ambient light.
14. Trigger mode:
No light pulse or
light pulse too weak
• Is intensity or duration of light pulse too low?
If necessary increase values using PC control
(also see Section 8.6).
