Trouble Shooting
The following describes some possible errors and the solutions to correct the errors.
Error:
Dolly and HCU are not functioning in wireless mode
Solution:
Check
o Are the HCU and column equipped with wireless modules?
o Is the emergency OFF Switch inserted into the off position? If so, twist clockwise
to deactivate.
o If the HCU battery is in place. The wireless mode does not work without battery.
o Are the HCU and electronic synchronized? If not, connect via the HCU cable.
o Are both the HCU and electronic sending and receiving on the same channel?
Error:
In wireless mode there is a disturbance in the movement of the column.
Solution:
Select the next or any other channel e.g. 4.
If this doesn’t help, change to cable operation.
Check the battery voltage with a loaded column. Should the voltage fall below 19V replace
or charge the batteries.
Check the motor temperature. In general terms the following can be said about the electro-
motor:
The hotter the motor becomes, the higher the performance loss. Should the motor reach a temperature of
60°C the column will shut down automatically to avoid permanent damage. However, it is suggested to avoid
use of the column when the temperature exceeds 50°C.
If the above solutions do not result in an improvement of the columns performance please service the
column (see “servicing the column”).
