Parameter “Error report”
This parameter defines the error report status of the system, controlled by 1 byte data bit. Options:
Disable
Enable
There is an error report after the malfunction in the system when selecting “
enable
”, otherwise, there is no
report when selecting “disable”. It will send an alarm to switch off the device if with over temperature, overload
or short circuit.
In the case of the universal dimmers, the stabilization time of temperature is 1min. in the program application.
When the temperature is higher than 70
℃
lasted for more than 1min., the dimmer changes its output into 30% of
the current brightness; when the temperature dropped to 60
℃
, the dimmer changes its output into 50% of the
current brightness. When the temperature is higher than 90
℃
lasted for more than 1min., the output turns off and
cannot start, until the temperature drops below 90
℃
the output can be restart via sending the output command. If
the temperature fluctuations at the critical point, the stabilization time will re-timing. Only when the stabilization
time (1min.) has elapsed, the current output brightness changes.
In the case of the 350mA LED dimmer, when the
radiator
temperature is higher than 75
℃
, the brightness
value of LED lighting will come down, if the temperature continues to rise, the brightness value will continue to
fall. The output is turned off in 90
℃
.
Note: the 350mA LED dimmer only report over temperature. Because of constant current output,
there is not overload, if short-circuit, automatic disconnect output, but no report.
In the case of the 4A LED dimmer, when the
radiator
temperature is higher than 70
℃
, the brightness value of
LED lighting will lowered 5% per
↑
1°C, if the temperature continues to rise, the brightness value will continue to
fall. The output is turned off in 80
℃
.
In the case of the dimming master, there is only temperature report to the dimming slave. Although the slave
also has short-circuit protection, but the master will not report to the bus. When short circuit occurs, the output is
automatically disconnected from the slave, if you want to resume its output, the error needs to be removed, then
open the slave housing, and remounted. when the slave temperature is higher than 75
℃
, the brightness value of
lighting will lowered 10% per
↑
1°C, if the temperature continues to rise, the brightness value will continue to fall.
The output is turned off in 85
℃
.
In the case of the Triac dimmer, it only report over temperature. When the radiator temperature is higher than
70
℃
, the power output is halved, that is, the brightness value becomes 50% of the current brightness, such as
80% down to 40%. The output is turned off in 80
℃
. If there is short-circuit, it will disconnect output
automatically, but no report.
