11.4 Error codes
Some error codes are displayed in the RC1xx’s front panel; these are shown
in red.
Error
number
Reason
Err 1 A parameter value is invalid.
Err 2 Command not recognised.
Err 3 A numeric value is in the wrong format.
Err 5 This is a warning, not an error. One of the parameters
is out of range and the value of that parameter has
been adjusted. For example, sending an RT command
with a delay of 0µs returns an ‘Err 5’. The command is
accepted, but the delay is set to the minimum allowed.
Err 8, 12 EEPROM corrupt. The conguration has been cleared.
Err 9, 20 Settings could not be saved to EEPROM.
Err 19 A light has been connected but no rating has been set.
Err 21, 22,
23
A sensing error has occurred (see Section 7.8, “Fault
detection”).
Err 27 Ethernet settings cannot be read from the EEPROM.
They may be incorrect.
Err 34, 47,
PO
The internal power dissipation is too high. Output
turned o.
Err 35, OP The output current to the light is too low.
Err 36, SH The output is short circuit.
Err 37, HI The voltage required for the lighting has increased too
much. Check for ageing of the light or a failed LED.
Err 38, LO The voltage required for the lighting has decreased too
much. Check for ageing of the light or a failed LED.
Err 39 The internal protection has prevented the SafePower
voltage going too high.
Err 40, 41,
45, FAC
Fatal error: The unit is outputting more current than
expected.
Err 42, SH The output current is too high.
