The CLIC will remain in its power-up state until programmed by sending the inverse of the desired command word
followed by the desired command word. Example: To set CLIC in active state with command ’C8’, the inverse of
’C8’, ’37’, followed by ’C8’ has to be sent. To set CLIC in standby state with command ’CA’, the inverse of ’CA’, ’35’,
followed by ’CA’ has to be sent. Once this has been done the CLIC is enabled to take single-word command. The
Power-up state is Open Circuit and no Relay Driver activated.
