The functionality of the Cyrix-Li-ct is analogous to the Cyrix-ct.

The Cyrix will disengage immediately:

• when its control output becomes free floating, signalling cell over voltage or cell over temperature, and/or
• when battery voltage drops below 13,2V. Start assist function: a short positive pulse will close the relay during 30 seconds

A built-in transient voltage suppressor will limit the voltage spike that may occur when the Cyrix suddenly disengages due to cell overvoltage or over temperature.
