RC1xx - User Manual
7.6 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 is 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 out-
put current.
SH
Output voltage is too low. The RC1xx detects that the out-
put 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.
7.7 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.
Clear the configuration from the front panel by pressing and holding SEL
and
q
for about 5 seconds, until
COL
is displayed. You can also clear the
configuration by using the CL command (see Section 10.3.3, General
commands ).
You can start the RC1xx from a powered down state (cold boot) with the
front panel keypad locked; this process removes the keypad lock.
