TERMINAL INSPECTION
Visually inspect the terminals and the area immediately around them in the front and/or rear panels and clean
them if required. IF THE INTERNAL SURFACES OF TERMINALS ARE WETTED DURING CLEANING, THEN ENSURE
THAT THEY ARE FULLY DRIED BEFORE OPERATING THE 95x AT HIGH VOLTAGES, OTHERWISE SAFETY MAY BE
COMPROMISED.
Carefully visually inspect the high voltage terminal shrouds for mechanical damage. If there is any cracking in the
shroud, then safety may be compromised, and the terminal should be replaced. Replacement of high voltage
terminals should only be carried out at Vitrek or one of its certified repair establishments.
SELF TEST
Prior to performing a self-test, the 95x must have been continuously powered and turned on for at least 5 minutes.
The user may press the
STOP
button at any time during the self-test procedure to abort it. The
HIGH VOLTAGE OR
HIGH CURRENT PRESENT
warning symbol is illuminated whenever high voltages are present on the 95x terminals
during this procedure.
Perform the following to command an automatic self-test procedure
–
•
Ensure that the display indicates that the 95x is in the base menu state, i.e., the display shows the date
and time. If necessary, press the
STOP
button to abort a menu and return to the base menu state.
•
Press the
TEST
key.
•
The display now shows a series of temporary messages indicating the status of certain portions of the 95x.
If any of these indicate a failure of the 95x, then the self-test is halted at the failing test.
•
The display now shows a message indicating that the user should remove all leads to the 95x. The user
must remove all connections to the terminals of the 95x before continuing with the self-test.
CAUTION
–
high voltages may be present on the
HV
terminal of the 95x during the remainder of the self-test
procedure, the user should ensure that there are no connections and that the terminals are not touched
during the procedure. When sure that all connections have been removed, the user should press the
START
button to continue the procedure.
•
The display now shows a series of messages indicating the progress as several active circuitry tests are
performed automatically by the 95x. If any of these indicate a failure of the 95x, then the self-test is
halted at the failing test.
•
When all tests have successfully completed, a temporary message is displayed, and the display is returned
to the base menu state.
