RTxxx LEDlighting 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 tolighting 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.
