Autoflow to Actuator Interconnect
The actuator control box houses the 24V DC linear actuator, two (2) 12V DC batteries and a 24V DC
battery charger. The linear actuator raises and lowers the dump chutes to unload grain automatically from
the drying chamber to the storage chamber. The two (2) 12V DC batteries act as a back-up to prevent wet
grain from dumping into the storage chamber during a power outage. The 24V DC battery charger
provides a continuous recharge to the batteries.
To wire the actuator control box to the Autoflow control box do the following.
1. Run five (5) control wires from the Autoflow control box to the actuator control box.
2. Run three (3) power wires from the entrance panel to the actuator control box.
3. Connect the wires as shown in Figure 4F .
