Adjustment instructions for the JUMBO application
Tool
For the adjustment you must use a trimming screwdriver, which can be purchased from LINAK
A/S. It is also possible to use other types of trimming screwdrivers for the adjustment.
Ordinary screwdrivers cannot be used, as they will damage the potentiometer slot.
When you receive the JUMBO from LINAK A/S it is adjusted to min. current cut-off.
1. Connect the JUMBO control box to the actuator.
2. Load the actuator with the required load.
3. Turn the potentiometer completely clockwise.
4. Run the actuator in the loaded direction at the same time turn the
potentiometer anticlockwise until the actuator stops.
5. Turn the potentiometer 3 times clockwise.
6. Check JUMBO can lift the loaded actuator.
7. Insert the plugs article no. 0009020 (light grey, RAL7035) or 0009019 (dark grey, RAL 7016) to
ensure IP protection.
Only the end with the lowered notch must be used
for adjustment of the potentiometer.
