VPFCCS > 1.7 V
- PFC driver stopped
Wait for next starter
event
Fault with timed activation of latched operating mode
PFC static OVP
VCOMP < 2.25 V
- PFC driver stopped
- Tch cycle starts
- At the end of cycle, if VCOMP <
2.25 V IC is latched
Check the mains
voltage
Lamp end-of-life
VEOL outside
allowed range
(set by REOLP)
- Tch cycle starts
- At the end of the cycle if VEOL
is out of range the IC is latched
Replace the lamp
with a new one
Lamp over-current
Ignition:
VHBCS > 1.6 V
- Frequency control activated
and Reduced Tch Cycle (RTC)
starts
- At the end of RTC the
threshold is reduced (1.05 V
during ignition and 0.82 V
during run mode)
- If VHBCS>reduced threshold IC
is stopped
Replace the lamp
with a new one
Run mode:
VHBCS > 1.05 V
Lamp ageing
causing hard
switching
VHBCS > 2.75 V
- After 350 subsequent hard
switching events IC is stopped
Replace the lamp
with a new one
