Lockout Disable
Reduces the standby-delay time from 3 minutes to 3 seconds. This can be useful when
diagnosing start-up problems. This feature should be used with caution! If the lamp has been on
and the display is turned off, it needs several minutes to cool down before attempting to re-
ignite the lamp.
When an arc-lamp of this type is first turned on, the power supply has to produce between
4000 and 30,000 volts to heat the gas in the lamp to start the illumination reaction. As the gas
heats up, the voltage drops to the operating voltage of around 90 volts. If an attempt is made
to restart a hot lamp, the initial surge of high voltage will cause permanent damage to the lamp
– significantly reducing it’s life.
The 3 minute standby-delay prevents re-ignition of a hot lamp. By selecting the Lockout
Disable feature it is now possible to attempt to re-ignite a hot lamp.
Reset System Hours
Erases the accumulated system hours and restarts the timer at zero hours.
Initialize EEPROM
Erases all stored data from the display’s memory including all user saved settings, system
hours and lamp hours.
