5.6 Switching off
When the Off button on the UV control is pressed, the UV lamp
switches off once the set post-burning time has elapsed. The fac‐
tory setting is 30 seconds.
If you wish the UV lamp to switch off as soon as you have pressed
the off button, then you need to set the post-burning time to 0 sec‐
onds.
5.7 Cool down
As the UV lamp can only be re-ignited after switching off of the UV
system and sufficient cooling, the system goes into cooling down
mode.
During cooling mode, the UV system cannot be started. After the
pause status has been cleared during cool-down or
[START] has
bee pressed during cooling down, the UV system only restarts after
the cooling-down period has ended.
5.8 Behaviour should the supply voltage fail
If the power fails, once the power supply has been reconnected the
UV system returns to the operating status in which it was before
the power failure.
40 seconds are needed to ramp up the HMI. The PLC (Program‐
mable Logic Controller) is ready for operation considerably faster.
To avoid ambiguous operating indicators and operating statuses,
operation is only enabled after 45 seconds.
When operation starts, all pending faults are reset if these faults
are no longer present. If the wiper is not in the home position, it is
moved back. If the power fails while the UV system is in operation,
then the system is always cooled down before being started
regardless of how long the power failure lasted. The cooling-down
phase is not shown on the display, but runs in the background. If
the power failure occurs while the UV system is cooling down, the
cooling down process is continued after the power has been
switched on again.
Should an automatic start not be desirable due to external compo‐
nents, the UV system must be switched from external to pause.
External faults result in a UV system fault, which then has to be
acknowledged. Separate acknowledgement can thereby be
avoided.
