6.4 Crane Scale
6.4.1 General Functioning
Before operating a crane scale, make yourself familiar with the general
functioning of your DISOMAT.
Ground-controlled crane scale:
Start basic functions via control unit (pendant or remote control). Output information
on weight and system status on large-size display. Enter all further settings on
DISOMAT keyboard.
Information from ground-controlled crane scale is output on large-size display
DLZ 055/DLZ 111 (weight value, error information, status messages):
Scale tared = Net
Scale exact zero = -0-
Printing active = Yellow LED
