Test Run - Siemens SIMOTICS XP 1MB1 series Operating Instructions Manual

machine, inadequate alignment of the machine set, operation of the machine with the
system resonating (system = machine + base frame + foundations etc.).
● If the machine runs perfectly in terms of its mechanical operation, switch on any cooling
devices present and continue to monitor the machine for a while as it idles.
● If it runs perfectly, connect a load. Check that it runs smoothly.
Read off and document the values for voltage, current, and power.
Where possible, read off corresponding values for the driven machine and document
them as well.
● Monitor the bearing temperature, winding temperature, etc. until the system reaches a
steady state.
Document these, provided this is possible with existing measuring instruments.
NOTICE
Destruction of the machine
The machine can be destroyed if the vibration values are not strictly complied with.
• In operation, maintain vibration values in accordance with DIN ISO 10816-3.
● Start the machine without a load; to do this, close the motor starter protector and do not
switch the machine off prematurely.
● You should limit how often you switch the machine off while it is starting up and still
running at a slow speed, for checking the direction of rotation or the required dimensions,
for example.
● Allow machines to reach a standstill before switching them back on.

Test run

After installation or inspection, carry out a test run:
1. Start up the machine without a load. To do this, close the circuit breaker and do not
switch off prematurely. Check whether it is running smoothly.
Switching the machine off again while it is starting up and still running at slow speed
should be kept to a bare minimum, for example for checking the direction of rotation or for
checking in general.
Allow the machine to run down before switching it on again.
2. If the machine is running smoothly and evenly, switch on the cooling equipment. Continue
to observe the machine for a while in no-load operation.
