6 Use this to set the time duration for keeping the Interactive Depth Control function engaged
when the button on the Control Station has been depressed (3 to 60 seconds).
7 An ultrasonic transmitter has been installed on the lifting ram. It measures the so-called bit val-
ue to determine the exact position of the lifting ram. This shows the current bit value. The value
changes when the machine is raised/lowered.
8 Use this to throttle the raising/lowering of the drill when the C button has been engaged. This
results in slower operation when adjusting the drilling depth. 0% = no throttling; 40% = max-
imum throttling.
9 This displays the current bit value of the lifting ram.
!
To enable the system to correctly detect the lifting ram position, it must be calibrated as ex-
plained below. To determine the scale value, an upper and a lower calibration position are first
recorded.
10 Use this to record the desired scale value
when the machine is raised
. Basic setting is per-
formed by raising the drill 20 centimetres above ground. The scale value
-20.0
is then set. (It
is possible to set values between 0.0 and -99.5.)
11 This shows the current bit value when the machine has been lowered to the ground.
12 Use this to record the desired scale value
when the machine is lowered
. Basic setting is per-
formed by lowering the drill until it rests on the ground. The scale value
0.0
is then set. (It is
possible to set values between 0.0 and 99.5.)
13 To return to the "Low-lift/Drilling depth" menu, select OK and depress or depress
to cancel.
