Error codes
Some error codes are displayed on 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 4
Wrong number of parameters.
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 he delay is set to the
minimum allowed value.
Err 8, 12
EEPROM corrupt. The configuration 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 7.6, Fault
detection).
Err 27
Ethernet settings cannot be read from EEPROM. They
may be incorrect.
Err 34, 47,
PO
The internal power dissipation is too high. Output
turned off.
Err 35,
OP
The output current to the light is too low.
Err 36,
SH
The output is short circuit.
Err 37,
H1
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 SafePower
voltage going too high.
