EXPLANATIONS OF CONTROL MECHANISM OF ELECTRI-
CAL SYSTEM
This section gives the necessary knowledge for trouble shooting of the electrical system, and explains the
functions and nature of checks for the monitor panel and controller.
1. Explantion of functions
The control mechanism of the electrical system consists of the monitor panel and controller. It carries
out various controls such as stopping the work equipment in the interference area, setting the working
area (height, depth, offset), displaying the depth, and one-touch deceleration.
The monitor panel and controller each input the necessary signals, and at the same time, together with
the signals selected and set by the moitor panel, the controller inputs and outputs the necessary signals
to control the stopping of the work equipment, the setting of the working area (height, depth, offset),
displaying of the depth, and one-touch deceleration.
