4-5 TSE4041datasheet
Lightbulb Defect Detector
Sense the current through the shunt resistor RS. When one of the lightbulbs is defective, the failure is indicated by
doubling the flashing frequency.
Operation with Short Circuit Detection
Pin 6 has to be left open and a capacitor C2 has to be connected between Pin 1 and Pin 2.
Operation without Short Circuit Detection
Pin 6 has to be connected to Pin 2, and the use of capacitor C2 is not necessary. The circuit can also be used for
other warning flashers. In this example, when the handbrake is engaged, it is signaled by the light (L1).
Application Information
1. The flashing cycle is started by closing S1. The switch position is sensed across resistor R2 and RLamp by
Input 8.
Rst = R2 + RLamp. The condition for the start is: Rst < 3.6 kW. For correct operation, leakage resistance from
Pin 8 to ground must be greater than 5.6 kW.
2. Flashing frequency:
3. Flashing frequency in the case of one defective lightbulb of 21 W:
4. t1: delay at the moment when S1 is closed and first flash:
5. t2: defective lightbulb detection delay
6. t3: short circuit detection delay ,t3 = K1R1C1 In the case of short circuit – it is assumed that the
voltage
. The relay will be turned off after delay t3. The circuit is reset by
switching S1 to the off position.
7. Detector is not used. the capacitor C1 is not obligatory. In this case Pin 6 has to be connected to Pin 2.
8. When overvoltage is sensed (VPin2 – VPin1) the relay is turned off to protect the relay and the lightbulbs
against excessive currents.
