USER MANUAL
Rev. 3.0 - 26/02/01
The following are present on the front panel: an HT indicator which signals that the high
voltage supply is active; a switch to activate the HT supply, or put the unit in stand-by (ST.BY.
15 Fig.1); an on-off switch and corresponding indicator (14 and 16 Fig.1).
4.4
Protection System
The VJ1000 features protection against: excess VSWR, excess grid current, opening
of panels with the unit active, and insufficient ventilation.
Under abnormal conditions the unit will be automatically disactivated; after 90 seconds the
protection system will re-activate the unit if the condition has returned to normal, unless a
panel is still open or the cooling system lacks sufficient pressure.
In this event, the procedure is repeated four times, after which the unit will remain disactivated
for 15 minutes.
If, after 15 minutes, the condition is still present, four more switch-on attempts are made,
after which the unit is shut down indefinately.
Should, during these cycles, the fault condition dissappear and the protection system succeed
in re-activating the unit for more than 15 minutes, the fault condition counter will be reset to
zero.
N.B. The times indicated above are approximate and may vary considerably.
