(visual inspection). In the event of any abnormalities and unusual noise, take the table out of service
immediately and inform the operator.
Replace damaged or worn components immediately and do not use the table until it has been repaired.
The table complies with the safety regulations prescribed at the time it was placed on the market. Improper
repairs and structural modifications (disassembly of original parts, installation of third-party parts, etc.) may
result in hazards for patients and users. In the event of uncoordinated modifications to the table, the
Declaration of Conformity loses its validity and the warranty shall become null and void. We cannot be held
liable for damages resulting from uncoordinated modifications.
Only original Dewert spare parts may be used.
Risk of electrocution!
Work on the electrical system may only be carried out by qualified and authorised personnel in
compliance with all relevant provisions and safety regulations!
Foot and hand switches for adjusting the electric motor as well as gas springs are wearing parts whose
function may be impaired over the years depending on the frequency of use. Both can be replaced without too
much effort. Please request the corresponding installation diagram, if required. Replacement parts can be
obtained directly from Dewert.
7. Safety devices
Tables with electromotive adjustment must have an automatic device to deactivate the control elements when
moving the table. Reactivation of the control elements must be designed in such a way that they cannot be
triggered accidentally by patients, users or third parties.
The actuator of this table is equipped with an integrated safety device to protect against
unauthorised/unintentional opera
tion. This device goes into “sleep mode” 3 seconds after the last operation
and can only be reactivated with a defined switching sequence, the so-called double tap.
To “wake up” the actuator or the control unit, first press the desired direction of travel for approx. 1 second on
the control element. After a short waiting time (1-2 seconds), press the desired direction of travel again and
the actuator can be moved for a maximum of 30 seconds in this direction of travel.If the switching cycle of the
double-tap function is not observed, the actuator cannot be operated. After 30 seconds of operation in one
direction of travel, the actuator switches off and goes into sleep mode. The actuator can still be operated for
up to 3 seconds after the last operation to ensure fine adjustment. Within this time window, it is possible to
move in each direction of travel again for a maxim
um of 30 seconds. The actuator always goes into “sleep
mode” automatically 3 seconds after the last operation.
The motor is equipped with a
safety freewheeling clutch
as standard:
When lowering, the motor declutches automatically if an obstacle is encountered, and the flow of power is
interrupted. In other words, the active tractive force of the motor no longer acts; instead, simply the weight of
the upper part of the table is applied. In the event of unforeseen entrapment, the risk of injury is significantly
limited.
In addition, the table can be equipped with another option:
Foot switch cover
The top of the foot switch is fitted with a protective cover. This makes unintentional or unauthorised operation
more difficult.
