When cranking engine, vehicle electronics systems are in standby to prevent data loss, the heavy current draw of cranking combined with a full electronics suite can cause voltage drops severe enough to upset memorized settings. By delaying the equipment activation until after the engine is completely started, the on/on delay timer prevents data loss and vehicle down time.

• Emergency override switch provides a convenient way to restore power to your equipment by holding the button in.
• Electronic equipment protection system, computers, GPS, AVL and etc.
• Low / High voltage detection and shutdown.
• Automatic On/Off - no user intervention required
• Prevents battery deep discharge/li>
• Programmable with external DIP switch for selecting and adjusting time delay
• Built-in diagnostic red LED indicates timing functions active when flashing
• Engineered electronically for reverse polarity protection
• Potted compound construction. Solid state, sealed against vibration and moisture.
• Easy external connection with .250 male tab mating with .250 female disconnect
• Delay time range: from 15 seconds to 8 hours. Tolerance plus (+) or minus (-) 10%
• Allow 3-5 seconds for delay on break at ignition switch connection for delay activation
• For installation, connect the red wire (+) to a master switch and the black wire (-) to the battery negative post. Connect the blue wire to fuse block (AM/FM radio) or cigarette lighter.
