5 Curing
5.2 Start Exposure Cycle
The exposure cycle is triggered by pressing the foot switch or pushing the button, or by
an external start signal via PLC interface.
☞
Note!
If the power of 1000 W is set every exposure cycle starts with a bulb warm up cycle of
approx. 5 seconds to ensure consistent radiation intensity as soon as the shutter opens.
Frequent on/off switching results in premature deterioration of the lamp.
Do not switch off for idle periods of less than 3 hours.
Position part in the cure chamber.
Close door of cure chamber.
Select desired exposure time.
Press foot switch.
During exposure, seconds are counted backwards on the display, starting with the warm
up time and followed by the cure cycle. When the cure cycle is finished, the shutter
closes, and the UV bulb switches back to 500 W. This happens only if a power of 1000
W and the time mode is set.
The door of the cure chamber can be opened when the shutter has closed. A relevant
message will be indicated on the display.
☞
Note!
Required exposure times are dependent on the type of product used, on part
characteristics and on distance to the lamp. Tests should be conducted to determine the
most suitable settings for each specific application, using the times specified in the
product data sheets as guidelines.
5.3
Shutdown
Turn the button until the “
Turn off
” menu option is displayed.
Push button to confirm shut-off. The device is switched off.
The system cools the bulb down until 100 % cooled.
Switch the system off.
5.4 No Uncontrolled Shutdown
CAUTION!
The UVALOC can only be switched off via the "Switch off" menu because it is the only
way the burner is controlled cooled down.
The switching off via power switch
1
leads to significantly higher wear and thus to a
shorter life time of the burner because it is not controlled cooled down.
