Error Codes (LED Head)
X= LED Input CH.1, CH.2, CH.3, CH.4.
Er-1;
The head(X) has exceeded the allowable operating
temperature. (error code will remain present until
cleared, however the head will be operative again when
the temperature is below the maximum allowable).
The
channel select button is not required to clear this error.
Subsequent triggers will clear the alarm if the
temperature of the LED has recovered to below the
over-temperature cut-off threshold. (This applies to the
front panel Start/Stop button, Foot Pedal, and PLC I/O
Start/Stop inputs).
Er-2;
The head(X) has failed to emit light when turned on.

head will continue to be activated during subsequent
exposures. This is to allow the heads to be re-activated
after a safety interlock triggered fault.

(The head will remain disabled until the power is cycled).
