power limiting
during operation
power limited to ballast max value;
lower lamp current not to exceed power max value
(power limiting prioritized)
current limiting during preheating current limited to ballast max value
during operation
broken electrodes
during preheating
turn off affected lamp channel
no lamp connected during preheating turn off affected lamp channel
during operation
mains voltage monitoring during preheating
during ignition
during lamp operation
turn off all lamps
if mains voltage too low or too high
brownout/blackout detection during preheating turn off all lamps,
detection during lamp operation restart lamps without preheating if
brownout/blackout duration is below max value
overheating protection
during preheating
during ignition
during lamp operation
turn off all lamps,
if ballast heat sink temperature above max value
Notes on safety mechanisms:
• If temperature is too high or if undervoltage is detected the appropriate LEDs are lighted.
The ballast cannot be started in that state.
• The ballast will never automatically restart any lamp after safety shutdown.
• The ballast should not be started until the reasons for safety shutdown are removed.
The ballast might be damaged by:
• overvoltage at mains terminals, even if the overvoltage occurs just for short time
• short circuits, incorrect wiring, loose contacts.
Note:
• all dimensions and technical data may vary within small tolerances
• no warranty for completeness and correctness of details
• all information provided in this document is subject to change
•
The unit must not be used for equipment that is used for medical treatment or for life saving measures
without prior written permission of the manufacturer.
