Voltage mode Configuration Protection
Open cathode (one cathode disconnected completely) conditions are detected using the CS pin.
Open filament condition is detected in the lower cathode using the pin SD. In the case of open
filament in the upper cathode, the lamp preheats and ignites without causing over-current in the CS
pin, this is usually not a problem. However, we propose a circuit that has shutdown for open filament
as well using the SD pin (schematics of the whole circuit in the following page).
When the upper filament is connected, the transistor base is supplied with current via the 220K
resistor from the DC bus. This keeps it switched on at all times while the upper filament provides a DC
path. When the transistor is on the diode anode is held close to 0V so the SD pin is not affected by
this circuit and stays at 2V.
When the upper filament is open circuit, the transistor looses its base current and switches off so the
diode conducts and pulls the SD pin above the 5V threshold causing the system to shutdown. When
the lamp fails in this way and is replaced, the transistor will switch on and so the ballast will restart
without resetting the AC line.
Current mode configuration
The same PCB can be configured for current mode heating. It is needed to remove the Jumpers JV1
and JV2 and to introduce the Jumpers JC1 and JC2. It could be also usefull to add a resistor RDC in
parallel to CDC because in this configuration After initial start-up you could have some striations
(visible dark rings) on the lamps for a short period (a few minutes) particularly when the lamp has
been off for some time and is cold. The value should in the order of 100kOhm 0.5W.
We suggest the use of the Ballast Designer software to determine the values of the components to
use in this configuration.
