Temperature Protection
4.5.1.
120VAC
The AC light will reduce the current output of the driver up to half the total value if an overheating condition is
detected by the driver. The light will have to be power cycled to return to normal operation.
4.5.2.
24VDC
The DC light driver will reduce the light output of the driver to 15% of the maximum light output. The user will
not be able to increase the light output until the light driver has detected that the temperature of the board has
gone below approximately 50° Celsius. Once the light driver has gone below 50° Celsius, it will automatically
return to its original light output level.
4.6.
Electrical Protection
4.6.1.
24VDC
The DC light driver will stop the light output if it detects a MOSFET over-current, output over-voltage, or an LED
over-current signal. If light is configured for 0-5V or 0-10V control, refer to section 6.4 for troubleshooting. If
light is configured for RS485 control, the user can issue a
“
Get Error Status
”
command to check if the driver is in
electrical protection mode.
CAUTION
Complete troubleshooting prior to restoring power to a light that has stopped to
avoid energizing a shorted unit.
The light can be returned to normal mode by power cycling the unit, but refer to section 6.4 prior to doing so to
avoid energizing a shorted unit.
