control unit XLC4-1 and XLC4-1A
pin | name | description | |
---|---|---|---|
1 | ON | IN | switch signal for PWM mode operation
|
2 | PWC | IN | control signal for PWM mode operation
|
3 | ENC | IN | do not use |
4 | FAIL | OUT | failure signal
|
5 | STAT | OUT | do not use |
6 | COMMON | GND | common ground for pins 1 – 5 |
7 | SW1 | switch | |
8 | SW2 | switch |
The signal ON switches the Corona II module to PWM-controlled mode.
The duty cycle of signal PWC controls the LED current in PWM-controlled mode.
The signal FAIL sets error states in PWC-controlled mode, Bulb mode and Analog mode. Refer to PWM-controlled mode for further information.
The two inputs ON and PWC are opto-coupled inputs. They both use the ground line COMMON.
The output signal FAIL is opto-coupled with an open collector circuit to the ground line COMMON.

pin | name | description | |
---|---|---|---|
1 | ON_1 | IN | external LED control channel A |
2 | ON_2 | IN | external LED control channel B |
3 | ON_3 | IN | external LED control channel C |
4 | FAIL | OUT | failure signal |
5 | STAT | OUT | do not use |
6 | COMMON | GND | common ground for pins 1 – 7 |
7 | ON_4 | external LED control channel D |
Signal ON - input characteristics
control unit XLC4-1
ON Max voltage | Input voltage ON ≤ 12 V |
ON Max current | Input current ON ≤ 15 mA |
ON Low current | Input current ON < 0.2 mA |
ON High current | Input current ON > 0.7 mA (Recommended > 2 mA) |
control unit XLC4-1A, XLC4-1F4
ON Max voltage | Input voltage ON ≤ 25 V |
ON voltage | ≥ 2.5 V |
OFF voltage | ≤ 0.7 V |
Signal PWC - input characteristics
PWC Max voltage | Input voltage PWC ≤ 6 V |
PWC Max current | Input current PWC < 15 mA |
PWC Low current | Input current PWC ≤ 0.7 mA |
PWC High current | Input current PWC > 1.3 mA (Recommended > 5 mA) |
If PWC needs higher voltages use a series resistor.
Signal FAIL - output characteristics
FAIL Max voltage | Output voltage FAIL ≤ 12 V |
FAIL Max current | Input current FAIL ≤ 15 mA (Recommended 5 – 10 mA) |
NOTE
The output transistor of FAIL is switched on if no error is set. Use a pull-up resistor in the receiver. An interrupt at the FAIL signal line causes an error (FAIL = H) at the receiver.
Sample circuit
NOTE - resistor value
The resistor value refers to the supply voltage of 24 V. Calculate the value of the resistor dependent to the supply voltage of the power supply.
Signal SW1, SW2
SW1 and SW2 ports are used to activate an external cooling device. When the programmed level is reached, the connection between SW1 and SW2 is closed.
The maximum current within the internal switch is limited to 1.5 A
The voltage at SW1 and SW2 must be lower than the supply voltage
The voltage at SW1 must be higher than the voltage at SW2
