RTxxx LED lighting controllers - User Manual
13.4 Fatal error codes
Error number
Reason
Err 44
The RTxxx is too hot. The RTxxx has a thermal
cutout which operates around 65°C to 70°C,
depending on conditions.
Err 40, Err 41
Err 45
One channel is outputting more current than
expected.
Err 46
One channel is dissipating more than 30W.
Err 47
Internal protection has prevented too much heat in
the output driver.
13.5 Event codes
Event messages are sent when a light is connected or an error occurs. The
format of these is:
Evt<channel>,<event code>;
These event messages are only sent after the
GT1 command has been
sent.
Event number
Reason
1 to 127
An error has occurred. The error code is given by
the event number.
128
A light has been connected and is working.
129
A light has been connected but doesn’t have a
current or voltage rating.
130
An over temperature error occurred.
131
An over current error occurred.
132
An error has occurred while autosensing the rating
of a light.
138
SafePower trainup has completed.
139
SafePower trainup has failed or been cancelled.
140
In switch output mode, the light has been turned
off because the duty cycle is too high.

RTxxx LED lighting controllers - User Manual
13.3 Error codes
Error number
Reason
Err 1
A parameter value is invalid.
Err 2
Command not recognised.
Err 3
Numeric value is the wrong format.
Err 4
Wrong number of parameters.
Err 5
This is a warning, not an error. One of the para-
meters is out of range. The value of the parameter
has been adjusted. For example, sending an
RT
command with a delay of 0 gets a reply of ‘Err 5’.
The command is accepted but the delay is set to
the minimum allowed value.
Err 19
A light has been connected to a channel but no rat-
ing has been set.
Err 8, 12
EEPROM corrupt. The configuration has been
cleared.
Err 9, 20
Could not save settings to EEPROM.
Err 21, 22, 23
Sensing error. See Section 6.2, Light auto-sensing.
Err 27
Can’t read Ethernet settings from EEPROM, so
these may be incorrect.
Err 34, 47
Internal power dissipation is too high. Output turned
off.
Err 35
Output current to lighting is too low.
Err 43
The requested output current requires too high a
voltage.
Err 36
The output is short circuit.
Err 42
The output current is too high.
Err 37
The voltage required for the lighting has increased
too much. Check for ageing of the lighting or a failed
LED.
Err 38
The voltage required for the lighting has decreased
too much. Check for ageing of the lighting or a failed
LED.
Err 39
Internal protection has prevented SafePower
voltage going too high.
