Q4 CONTROLLER II Operation and Maintenance Manual 1. Glossary Actuate/De-Actuate: These terms are used instead of ‘make’ and ‘break’ to allow us to distinguish between performing an action due to an environmental condition and whether the contact may be closed (‘made’) or open (‘break’) because of our use of double throw contacts, and the option of normally energized relays. -
