General safety instructions
Danger!
Rotation of the drive shaft induces a voltage, which is applied to the connection terminals.
Danger!
The elevator machine has attachment points: screwed-on eye bolts. The attachment points are
designed exclusively for transporting the
elevator machine including brake and traction sheave.
Do not lift other loads such as bolted on
components, ropes lying on top, etc. with the attachment
points. Adequately sized lifting device must be used. Make sure nobody is in the area of path of
transport of the machine (danger zone).
Warning!
Depending on the operating conditions, the elevator machine can have high surface temperatures
of > 80°C.
Risk of burns!
If the installation situation does not provide sufficient personal protection, then this must be
provided by the customer in the form of additional measures.
If work has to be carried out on the machine at normal operating temperature, suitable
gloves must be worn.
Warning!
Warning of hand injuries!
Risk of injury from reaching into the rope guard.
Do not carry out any activities during operation.
Only perform maintenance work on the drive when stopped.
The elevator machine is only to be operated within the ranges specified on the plate of the
machine!
Use the elevator machine only in the authorised fashion and only for the tasks and flow media
specified in the order!
If the elevator machine is not energized, no electric torque is available. Releasing the brakes can
cause uncontrolled acceleration of the elevator.
We recommend short-circuiting the windings of the de-energized elevator machine to generate a
brake torque dependent on the speed.
In the event of a short-circuit, a short-circuit current of at least the level of the rated current is
flowing.
The windings may not be short-circuited when the elevator machine is energized.
Safety features, for example the brake release monitoring, may not be dismantled, circumvented or
made inoperative!
Thermistors installed in the winding act as protection against excess temperatures in the elevator
machine and must be evaluated. When the thermistors are activated, the energy supply to the
elevator machine must be switched off (Safety chain). Thermistors must be monitorized by a proper
thermistor protection relay (max tension in the measure circuit is ≤2.5Vdc). Typical wiring diagram
is as follows:
