The control box for pressing and tapping lubrication
The automatic control box comes in two varieties, the AC-9 and the AC-8. The AC-9 accepts a signal from the equipment end (a non-voltage contact) and the AC-8 operates with input from a limit switch. After receiving a signal, the AC-9 adjusts the delay until the next spray (the standby time). It can be set to spray as frequently as the user prefers; for example, it can spray once per three signals received. The AC-8 can only set the spraying time, and is usually used together with the Tap Touch, an automatic tap lubrication device. Both operate on 100 VAC.
