Work procedure for wall sawing
3.3 Change the start point for blade motion
The start point value should be adjusted so that the
blade motion is as low as possible when the blade
motion knob is in the zero position, i.e. in the middle of
the left and right end positions.
A too low value results in the need to turn the knob
further from the zero position before the blade motion
starts.
A too high value results in the blade motion being too
high when the knob is turned from the zero position.
State the start point value:
• Press OK when the part menu is shown.
• Press OK.
The display shows: CHANGE START POINT and a
percentage value.
• Scroll using the arrow keys to state the required start
point. Hold the arrow key held down to increase the
scrolling speed. The scale is graduated from 1-100 %.
• Press OK.
• Press the down arrow to continue to the next part
menu.
3.4 Change the end point for blade motion
The end point value should be adjusted so that the blade
motion speed is as high as possible when the blade
motion knob is turned to the right.
A too low value results in the full blade motion speed
never being reached.
State the end point value:
• Press OK when the part menu is shown.
The display shows: CHANGE END POINT and a
percentage value.
• Scroll using the arrow keys to state the required end
point. Hold the arrow key held down to increase the
scrolling speed. The scale is graduated from 1-100 %.
• Press OK.
• Press the down arrow to continue to the next part
menu.
3.5 Change the ramp time for the feed
The ramp time value states how quickly the feeding speed
shall change when the blade motion knob or the trolley
motion knob is turned.
The defined ramp time value for feeding applies to both
for the blade motion and the trolley motion speeds.
State the ramp time value:
• Press OK when the part menu is shown.
• The display shows: CHANGE RAMP TIME and the
24 - English
time in seconds.
• Scroll using the arrow keys to state the required ramp
time. Hold the arrow key held down to increase the
scrolling speed. The scale is graduated from 0.0 to 9.9
seconds.
• Press OK.
• Press the down arrow to continue to "Back to the
menu".
4 Sensor on/off calibrate
This sub-menu contains the setting options for the
hydraulic unit's different pressure sensors.
The sub-menu consists of seven part menus:
4.1 Temperature sensor for hydraulic oil
4.2 Voltage sensor
4.3 Pressure sensor for hydraulic pressure
4.4 Calibrate pressure sensor for hydraulics
4.5 Calibrate voltage sensor
4.6 Calibrate potentiometer
4.1 Temperature sensor for hydraulic oil
A temperature sensor is fitted by the water coolant duct.
The sensor ensures that the water coolant is connected to
the hydraulic unit. The water coolant cools the hydraulic oil.
When the temperature sensor is on, the control system
continuously reads the temperature.
NOTE!
The hydraulic unit can be damaged, if the
temperature sensor is switched off.
Turn on/ turn off the temperature sensor:
• Press OK when the part menu is shown.
The display shows: TEMP. SENSOR FOR HYDR. OIL
and ON or OFF.
• Press OK to switch between ON and OFF.
• Press the down arrow to continue to the next part
menu.
4.2 Voltage sensor
A voltage sensor is connected to each phase, i.e. in total
three sensors. These measure the phase voltage to
hydraulic unit. Should the voltage be 10 % less than the
nominal voltage, the hydraulic unit stops.
