Fault detection
The TR-RC 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 TR-RC 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 TR-RC to sense the
light again.

Factory settings
You can clear the TR-RC 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
).
You can start the TR-RC from a powered down state (cold boot) with the
front panel keypad locked; this process removes the keypad lock.
