NOTICE
Damage if the auxiliary power supply is not available
When the auxiliary power supply is switched off, data about error message statuses can be lost.
Inadequate diagnostic and error rectification measures can result in material damage.
• We recommend using an uninterruptible power supply (UPS). If you are unsure of the
measures necessary after the device fails, or if a fault cannot be rectified, contact the Service
Center.
After performing repairs, refasten all cable ducts whose cover faces downward with a cable tie.
The cable ties must be located at the same positions as in the delivered state. You will find more
information in "Fastening the cable ducts with cable ties (Page 96)".
NOTICE
Damage caused by an incomplete repair
In the case of damage, several components can have a fault condition. Consequential damage
can occur if the device is recommissioned but the repair work carried out was not complete.
• Check whether secondary faults have occurred on components which have failed. Replace
the components involved.
Measures in the event of an error
It is not possible to fully test repairs that are carried out on site. Return the defective module back
to the manufacturing plant for repair. The relevant address is available from your Siemens
contact person.
Always enclose the following information:
• Type and serial number
• Time and date of the failure
• Description of the fault profile
Specify what happened when the component failed.
• Operating point, currents and voltages
• Log file with fault messages
• Copy of the CompactFlash card
• If possible, hard copies from the plotter or screenshots
• Mounting location
Specify the equipment identifier. You can find the item code on the component and close to
the slot.
