7.0 Troubleshooting
The following procedures can be used to diagnose and fix some common problems. They assume some
familiarity with instrumentation and electrics. If you prefer to not carry out these procedures yourself, or if you
need further advice, please contact Scientifica directly.
Adjustment or removal of any screws or components other than those noted in this manual
can adversely affect the performance and operation of your device and may invalidate your
warranty.
Dichroic mirror actuator jams.
Probable cause: foreign body in front part of the optics block.
o Remove the detection module from the SliceScope and remove any objectives / adapters
and telescopic tubes. Look through the laser entry and the objective ports to see if a foreign
object is obstructing the dichroic mirror / shutter mechanism. Do not open optical block but
look through laser entry/light port to identify the jam item. If easily accessible try and remove
the object carefully with tweezers. If fearful of touching mirrors call Scientifica for help. Do
not disassemble the main optical block.
No activity on the controller (meters and logo both fail to light).
Probable cause: power supply issues
o Check that the power supply is switched on and that the mains supply is present.
o Using a volt-meter, check that the power supply is delivering 12V DC. The central terminal
of the coaxial “barrel” style connector is positive with respect to the outer contact. Use of
inverted polarity will not cause damage but will prevent operation.
o If the power supply is dead, use an alternative supply (2.5 mm DC connector) which is rated
at 12V and 1 Amp to check that the controller is operational. Do not use any other voltage.
Contact Scientifica for a replacement low-noise power supply.
o If the power supply is operating but the controller is “dead”, check that the front-panel on-off
switch is activated – cycle it a few times.
o Try moving the DC cable and plug at the rear of the controller in case there has been stress
on the connector causing a bad contact.
o As a final check, try disconnecting the two detector cables (and any photodiode cable) one
at a time. If the controller starts to operate, then the fault lies in one of the detectors.
Contact Scientifica for help.
No high-voltage reading on either detector regardless of “enable” switch position or voltage controls.
Probable cause: safety interlock or connectivity issue.
