Rapid Startup
Use if your system will sit idle in the Standby mode
before moving to the On mode.
1. On the LAMP selector of the host machine (or
master control unit’s lamp selector), press the
Standby button. There will be an approximate
10 second warm-up time for the magnetron
filament.
2. After the 10 seconds the system will go into
standby and remain there indefintely.
NOTE: Do not leave the power supply in the
standby mode for longer than 30 minutes.
Prolonged standby periods will shorten the
magnetron life.
3. Press the On button to enable the UV light.
The light will turn on instantly but will take
approximately 8 seconds to stabilize. After the
8 seconds, the system ready output contact
(TB1) will close.
Standard Startup
Use to go directly through the warm-up to the On
mode.
1. On the LAMP selector of the host machine (or
master control unit’s LAMP selector), press the
LAMP On button.
2. During the next 10 seconds the unit will go
through the warm up cycle before turning to On.
3. After approximately 8 more seconds the unit
has stabilized and the system is ready to run.
The system ready output contact (TB1) will
close.
