Our repair services
Despite all efforts and accuracy in our production, a device may fail one day. In order to be able to help you fast and effectively in the repair case, we need some information of you. Please, fill in the form Repair Request EN DE. You can give all necessary information directly in the form. The red bordered fields are mandatory fields. Please, fill in this absolutely. Your information is required for the fault analysis and allows a smooth process.
Problems can be often removed in systems without service. In the failure case, please carry out the following steps, before you contact us:
Please refer to the manual what the message(s) the timer is showing mean. Many messages are diagnostic messages to locate a problem. Often the problem is outside the timer. Please follow the guidelines alone with the messages. Many problems can be solved quickly this way.
Check cabeling. Is a cable broken? This happens with frequently bended cables as the current and voltage measurement cable at an IQR MFDC inverter.
Do you have a spare timer available? In case you have the indication the timer is defect, please replace the timer with the original one. When the problem is no longer existing the timer is most likely defective.
The system must be powered down prior the exchange. Secure the system to prevent unintentional activation and ascertain the tension freedom. With tension more than 1000 V the device must be earthed and be short-circuited. You cover or barriers neighbouring parts standing under tension. On MFDC and HFDC systems please wait at least 5 minutes to discharge the capacitors. Please, do not open the device!
Follow the safety instructions in the manual of your device. Failure to follow the safety instructions may pose a danger to persons as well as result in damage to the module and/or system. Failure to follow the safety instructions renders any damage claims null and void.
If these first steps do not solve the problem, please complete the Service Request EN DE form. Click the Send button. The form will be automatically inserted into your E-Mail program and an E-Mail generated. You can add other important information, such as photos and logbooks, to this E-Mail.
Please, print one copy and attach it to the device before shipping it to one of our service locations.
