PP520 LED lighting controllers - User Manual
13.3
Error codes
Error
number
Reason
Err 1
A parameter value is invalid.
Err 2
Command is not recognised.
Err 3
Numeric value in wrong format.
Err 4
Wrong number of parameters.
Err 5
One of the parameters is out of range. The value of
the parameter has been adjusted. For example,
sending an
RT
command with a delay of 0 will get a
reply of 'Err 5'. When the settings are viewed the
delay will have been set to 20μs (PP520) or 4μs
(PP520F).
Err 8, 12
EEPROM corrupt. The configuration has been
cleared.
Err 20
Couldn’t save settings to EEPROM.
Err 27
Cannot read Ethernet settings from EEPROM; they
may be incorrect.
PO
, Err 34
Internal power dissipation is too high. Output turned
off.
OP
, Err 35
Output current to lighting is too low.
OP
, Err 39
There is not enough supply voltage for the requested
output current.
SH
, Err 36
The output is short circuit.
Err 42
The output current is too high.
HI
, Err 37
The voltage required for the lighting has increased too
much. Check for ageing of the lighting or a failed LED.
LO
, Err 38
The voltage required for the lighting has decreased
too much. Check for ageing of the lighting or a failed
LED.
Err 44
Temperature error. The PP520 is too hot and has
switched off to protect itself.
Err 40, 41, 45
More current is being output than should be, so the
PP520 has turned off the outputs. This may be
caused by a hardware error. Check with your
distributor.
