RTxxx LED lighting controllers - User Manual
Special note for RT8xxF controllers
: If you need to generate a variety of
output currents, the highest current loads should be connected to the
low-numbered output channels. For example CH1, CH2... This
minimises the spread of high currents on the internal PCB and helps
to maintain a low temperature rise in the unit.

Error codes
Error num-
ber
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 para-
meter 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
rating 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-sens-
ing.
Err 27
Unable to read Ethernet settings from EEPROM;
they 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.
