Switching Off - ProMinent 80 W Assembly And Operating Instructions Manual

Function
If the UV output falls below the safety threshold: The shut-off valve
closes and the rinse valve opens after delay time t0 has elapsed.
However, if the safety threshold is not exceeded again within rinse
time t1, then the control switches off the UV system and goes into
fault mode.
All UV lamps are monitored to ensure that they operate optimally. If
a UV lamp fails, the shut-off valve closes and the control switches
off the UV system and goes into fault mode.

4.3 Switching off

When the UV system is switched off, the shut-off valve closes and
the UV lamps are turned off. If the UV lamps require post-burning,
then the lamps are only switched off after lamp post-burn time t5.
