3.4 Detecting an Error
The reader controller circuit generates the error signal (INV_ERR) in response to an error
(e.g., output open, short circuit, leak) in the inverter circuit. A fault in the lamp (low inten-
sity, activation failure) will be identified as an activation error caused by lack of intensity
during initial activation (e.g., at time of shading correction).
