Fault detection
The RC1xx can detect a range of errors when connected to a light. The
displayed error codes are shown below with their reasons.
Error
Reason
PO
Internal power dissipation too high. Output turned off.
OP
Output current to lighting is too low. The light is open
circuit or there is not enough supply voltage for the
requested current.
Sh
Output voltage is too low. The RC1xx detects that the
output is short-circuited.
HI
The voltage required for the lighting has increased too
much. Check for ageing of the light or a failed LED.
LO
The voltage required for the lighting has decreased too
much. Check for ageing of the light or a failed LED.
Note:
When the output current falls below 100mA, some fault detection is
disabled. Press
SEL
to cancel the error and allow the RC1xx to sense the
light again.

Factory settings
You can clear the RC1xx configuration to return it to its factory settings:
The lighting rating is cleared and the light does not illuminate.

Ethernet address (RC120)
You may need to ask your network administrator for advice about setting
up the Ethernet connection.
The application note APP923 – Troubleshooting Ethernet problems is
available from www.gardasoft.com/Downloads.
The Ethernet set up of the RC120 is not affected by cold-booting the
controller.
