4.3 Repairs
Check all screws and bolts after the first week of use and tighten screws and bolts where necessary to
ensure safe operation of the table. If the table cannot be raised or lowered, check the cable connection
between:
The power supply and the motor/motor house (column system).
The handset and the motor/motor house.
The
columns/motors.
If the table still does not operate, the control system may have triggered the overheating or duty cycle
protection. Please wait for at least 18 minutes and try again before proceeding.
If a control unit is replaced, a manual reset is required. Follow these steps as section 3.2.
If the table is still not operational, please contact Martela or your vendor for further assistance.
The control system is equipped with safety features; the intermittency function and the overheating
protection and memory function
Duty cycle function – The duty cycle factor of the table 2:18 meaning 2 minute of operation
must be followed by 18 minutes of inactivity. If this limitation is exceeded, the table will be-
come inoperable until the control box resets automatically.
Overheating protection – The table will become inoperable if the overheating protection is trig-
gered and will return to operation automatically once the heat has dissipated sufficiently.
Memory function – The control system (each column) will retain information regarding the ele-
vation of the table at all times. This information will remain stored even in case of power fail-
ure or if the power cable is disconnected from the power outlet.
Soft start – Progressive acceleration allows for soft starts and stops.
Speed – the speed of the table varies with load.
4.4 Servicing of double-insulated products
In a double-insulated product, two systems of insulation are provided instead of grounding. No ground-
ing means is provided on a double-insulated product, nor is a means for grounding to be added to the
product. Servicing a double-insulated product requires extreme care and knowledge of the system, and
is to be done only by qualified service personnel. Replacement parts for a double-insulated product
must be identical to the parts they replace. A double insulated product is marked with the words ”DOU-
BLE INSULATION” or ”DOUBLE INSULATED”. The symbol (square within a square) is also able to be
marked on the product.
