Facility and safety devices maintenance
In order to ensure proper function and a long service life of your facility, the following checks have to
be performed after commissioning and then once a year!
•
Check and retighten all connections. Screwed connections may become loose at the beginning due to
thermal stress.
•
Check fuses, safety devices and switching equipment. Contactors are wearing parts. If the contactor is
intact, switching must take place without excessive formation of sparks.
•
Check the controller performance in automatic mode.
•
Examine the cool air proportions (ventilators, temperature monitoring function):
•
Clean filter mats, depending on how dirty they are.
•
Visual inspection of capacitors.
•
Examine the current input and capacitor terminal voltage.
b
Note!
The input current and the temperature of these facilities must be
checked regularly so that an overload on the capacitors can be
detected at an early stage.
A higher input current can be caused by an increasing proportion of
harmonics or by defective capacitors
