You can use the product to detect time and amplitude anomalies in the vibro-acoustic signal progression and receive event messages when anomalies are detected. The on-load tap-changer is equipped with measuring equipment that records the vibro-acoustic signal in the system throughout the entire tap change se- quence and analyses it immediately upon completion. In addition, the system determines the changed tap position and the oil temperature in the on-load tap- changer. Using the implemented algorithms, the monitoring system can reliably detect any potential anomalies that occur in the vibro-acoustic signal progression, tak- ing the temperature variations of the on-load tap-changer oil into account. 16 Product description 8459861/04 EN Status message The MSENSE® VAM monitoring system produces a 3-stage status message: Status Device/visualization display SCADA/digital output re- mote signaling Normal OK message through blue No remote signaling status message Warning The first and the second No remote signaling anomalies in an evaluation cluster are indicated via a yellow status message in the VAM analysis (Information menu).

Danger of death or serious injuries due to tipping or falling load. Only transport the crate when closed. Do not remove the securing material used in the crate during transport. If the product is delivered on a pallet, secure it sufficiently. Only trained and authorized persons may select the sling gear and secure the load. Do not walk under the suspended load. Use means of transport and lifting gear with a sufficient carrying capacity in accordance with the weight stated on the delivery slip. In addition to oscillation stress, jolts must also be expected during transporta- tion. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product. If a crate tips over, falls from a certain height (e.g. when slings tear) or experi- ences an unbroken fall, damage must be expected regardless of the weight. Every delivered shipment must be checked for the following by the recipient be- fore acceptance (acknowledgment of receipt): – Completeness based on the delivery slip – External damage of any type The checks must take place after unloading when the crate or transport con- tainer can be accessed from all sides. Visible damage If external transport damage is found upon receipt of the shipment, proceed as follows: – Immediately record the identified transport damage in the shipping docu- ments and have this countersigned by the carrier. – In the event of severe damage, total loss or high damage costs, immediately notify the manufacturer and the relevant insurance company. – After identifying damage, do not modify the condition of the shipment fur- ther and retain the packaging material until an inspection decision has been made by the transport company or the insurance company. – Record the details of the damage immediately on site together with the car- rier involved. This is essential for any claim for damages. – Photograph damage to packaging and packaged goods. This also applies to signs of corrosion on the packaged goods due to moisture inside the packag- ing (rain, snow, condensation). – NOTICE! Damage to packaged goods due to damaged sealed packaging. If the product is delivered in sealed packaging, check the sealed packaging im- mediately. If the sealed packaging is damaged, do not under any circum- stances install or commission the packaged goods. Either re-dry the dried packaged goods as per the operating instructions, or contact the manufac- turer to agree on how to proceed. – Identify the damaged parts. Hidden damage When damages are not determined until unpacking after receipt of the ship- ment (hidden damage), proceed as follows: – Make the party responsible for the damage liable as soon as possible by tele- phone and in writing, and prepare a damage report. – Observe the time periods applicable to such actions in the respective coun- try. Inquire about these in good time. 32 Packaging, transport and storage 8459861/04 EN With hidden damage, it is very hard to make the transportation company (or other responsible party) liable. Any insurance claims for such damages can only be successful if relevant provisions are expressly included in the insurance terms and conditions. 5.4 Storage of shipments Packaged goods dried by Maschinenfabrik Reinhausen Upon receipt of the shipment, immediately remove the packaged goods dried by Maschinenfabrik Reinhausen from the sealed packaging and store air-tight in dry insulating fluid until used if the packaged goods were not supplied in insu- lating fluid. Non-dried packaged goods Non-dried packaged goods but with a functional sealed packaging can be stored outdoors when the following conditions are complied with. When selecting and setting up the storage location, ensure the following: – Protect stored goods against moisture (flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites and so on, and against unau- thorized access. – Store the crates on timber beams and planks as a protection against rising damp and for better ventilation. – Ensure sufficient carrying capacity of the ground. – Keep entrance paths free. – Check stored goods at regular intervals. Also take appropriate action after storms, heavy rain or snow and so on. Protect the packaging foil from direct sunlight so that it does not disintegrate under the influence of UV rays, which would cause the packaging to lose its sealing function. If the product is installed more than 6 months after delivery, suitable measures must be taken without delay. The following measures can be used: – Correctly regenerate the drying agent and restore the sealed packaging. – Unpack the packed goods and store in a suitable storage space (well venti- lated, as dust-free as possible, humidity < 50% where possible). 5.5 Unpacking shipments and checking for trans- portation damages – NOTICE!
