3 Product description 3.1 Scope of delivery The product is packaged with protection against moisture and is delivered as follows: – COMTAP® ARS – TAPMOTION® ED motor-drive unit – Drive shaft with coupling parts and bevel gear – Technical files Note the following information: –...
The design of the COMTAP® ARS and the designation of its main parts are shown in the installation drawings in the appendix (see page [►Section 8.1, Page 28]). Figure 1: COMTAP® ARS 1 Tap-change supervisory control with 2 COMTAP® ARS head inspection window for tap position in- dicator 3 Upper gear unit...
3.2.4 Protective devices Tap-change supervisory control The COMTAP® ARS is equipped with a tap-change supervisory control, which is fitted in a housing on the head of the COMTAP® ARS (see page [►Section 8.4, Page 31]). Depending on the application, the tap-change supervisory control may have dif- ferent safety functions in conjunction with the motor-drive unit and the associ- ated on-load tap-changer units.
3.3 Drive shaft 3.3.1 Function description The drive shaft is the mechanical connection between the drive and the on-load tap-changer/de-energized tap-changer. The bevel gear changes the direction from vertical to horizontal. Accordingly, the vertical drive shaft has to be mounted between drive and bevel gear, and the horizontal drive shaft between bevel gear and on-load tap- changer or de-energized tap-changer.

4 Commissioning WARNING Danger of explosion! Explosive gases in the transformer, pipe system, oil conservator and at the de- hydrating breather opening can deflagrate or explode and result in severe in- jury or death. Ensure that there are no ignition sources such as naked flame, hot surfaces or sparks (e.g.
Switch off transformer on high and low-voltage side. Failure to do so may result in severe injuries and property damage. 2. Lock transformer to prevent unintentional restart. 3. Perform function checks as described in relevant MR operating instructions for motor-drive unit. NOTICE! An incorrectly coupled motor-drive unit will lead to damage to the...
5 Operation The following sections describe how to operate the COMTAP® ARS and monitor the COMTAP® ARS and motor-drive unit. 5.1 Temperature range When using a vegetable oil as insulating fluid, the permissible temperature range for operation of the DEETAP® DU/COMTAP® ARS is limited. Please observe the relevant information in the specific order documents and on the indicator plate on the drive.
5.3 Operating the motor-drive unit with the hand crank WARNING Danger of explosion! Unauthorized operation of the motor-drive unit with the hand crank may re- sult in death or serious injury. Never operate the motor-drive unit electrically or with the hand crank be- fore the transformer has been disconnected if you think there may be a fault in the transformer or on-load tap-changer / de-energized tap-changer.
5.4 Monitoring during operation Monitoring of the COMTAP® ARS and motor-drive unit is limited to occasional visual inspections on the COMTAP® ARS head and motor-drive unit. For effi- ciency reasons these visual checks can be combined with the usual checks on the transformer.
6 Maintenance 6.1 Safety precautions WARNING Danger of death and severe injury! An energized transformer and energized COMTAP® ARS components could cause death or serious injuries during maintenance work! Adherence to the following safety precautions is mandatory. 1. Switch off transformer on high and low-voltage side. 2.
In the event of faults on the COMTAP® ARS and motor-drive unit, which cannot be easily corrected on site, or if a protective device has been tripped, please in- form your authorized MR representative, the transformer manufacturer or con- tact us directly at:...
