Best service from a remote location, at any time, from virtually any place – that is the idea of our tool „digital Expert on Demand“, in short dEoD. This enables us at ABP to provide our customers with the very best possible remote troubleshooting support for their systems. This saves time and travel expenses – if successful, your system will be up and running again much faster, thus reducing downtime.
Prerequisites:
The first step in successfully assisting you with troubleshooting is to establish some basic prerequisites.
Safety
An ABP inverter system is a high-power system with voltages of up to 3000V. To work safely here, it is essential to become familiar with the specific safety aspects of working on a inverter system. For this purpose, ABP offers an online training as part of a dEoD contract, in which the risks and danger points as well as the safe working are covered in detail. This training is explicitly aimed at qualified electricians, as only they are allowed to work on the inverter. Furthermore, ABP also offers an optional basic package that deals with the necessary protective equipment.
Measuring tool
An appropriate measuring tool is essential for successful troubleshooting. This consists, among other things, of a multimeter that provides measurement capabilities for resistance, voltage (AC/DC), diode test and capacitance measurement.
An oscilloscope is also often necessary because faults in the inverter often occur dynamically, e.g. the breakdown of a component under voltage. The evaluation of such measurement images requires very good knowledge and experience with the inverter technology. This is why we would like to support you in the best possible way.
We work with a network-compatible soft oscilloscope that can be integrated via the Siemens router. Desired effect: The measurement images are directly available to the ABP service engineer. The required settings of the oscilloscope can be set remotely by the ABP service engineer.
To achieve the greatest possible continuity in this respect, we keep this measuring tool standardized. This allows us to ensure that the respective ABP expert does not first have to deal with the oscilloscope itself, which can cost valuable time in the event of system downtime. We have compiled the following measuring equipment, which has also proven itself under practical conditions:
• Soft oscilloscope, incl. 4 10:1 probes
• Current clamp 3000A
• High-voltage probe, 3kV
• Current clamp 20 A
Remote connection
ABP makes use of the proven and secure solution from Siemens to establish the connection. This establishes a secure VPN connection to your furnace system, which allows access to the PLC, the PRODAPT® and the DICU 3. This means that any program changes can be made
online, and the fault memory can also be read out. Test functions, which are often important for troubleshooting, can also be performed this way.
Please note: Access to older inverter electronics such as the DICU 2, which were still equipped with serial interfaces, is not possible here. However, ABP offers a quick and easy conversion to DICU 3 – please contact us for further information.
Data glasses
Data glasses can be used to send the images you see directly to the supporting service engineer so that they can guide you during the measurements. The advantage: You have both hands free to work! This in turn means that the service engineer can give you clear instructions. Alternatively, the image data can also be transmitted via smartphone.
To take full advantage of the opportunities afforded by data glasses or smartphones, we recommend setting up a sufficiently fast WLAN network in the area of the furnace system, especially in the inverter room.
