BASIC SYSTEMS & CONFIGURATION
The following section is intended to provide a general overview of the operation of the PROTECTOR IV with a
brief description of key components.
Digital Control Box
The Digital Control Box (DCB) is the heart of
PROTECTOR IV’s control system. It provides
excellent adjustability of the amount of grease
that is pumped from the tank to the bars. It
also provides integrity checks for verifying the
electronic controls and motor(s) are working
properly. The LCD screen at the top of the box
displays all of the information for the operator.
Pump
A double gear pump is coupled to the electric
motor. The pump/motor assembly distributes the
grease to the rails.
