For specific item types, refer to the technical catalog 1SCC303003C0201.ġ3. Are two pole change-over switches available?įor most of the switch products, ABB offers special two pole models.ġ4. Is it possible to use ABB change-over switches for DC applications? We recommend to a controller, a motorized change-over switch, one set of OMZB_ voltage sensing connectors and 2 pieces of OA1G10 auxiliary contacts. We recommend to order a controller, a motorized change-over switch and 3 sets of OZXT6 terminal clamp sets.ġ2. What are recommended accessories when ordering OTM160…3200 + OMD controller as two separate components? After the alarm has been shut off, the controller is in manual mode and you need to push AUTO button once.ġ1. What are recommended accessories when ordering OTM40…125 + OMD controller as two separate components? What do I need to do?įirst, you need to detect what the reason for the alarm is and shut it off - to check how to do it, refer to the user manual. If this is not done, the power source to motor does not work.ġ0. OMD controller shows an alarm. This means that you need to get it from a separate place and select the option 'Neutral in use' from the OMD controller. The OMD300 controller does not work without neutral line. This means that you need to get the neutral reference from a separate place or use a transformer.ĩ. Can the OMD300 controller be used in 3 phase system? The OMD200 controller does not work without neutral line. Select Motorized OTM_C option when connecting separate OMD controller and OTM motorized change-over switch.Ĩ. Can the OMD200 controller be used in a 3 phase system? You can use any brand that meets the requirements specified in the catalog.ħ. I have ordered an OMD controller as a spare part and after doing the connection correctly the product does not work as it should.Ĭheck the operating mode of the OMD controller. Notice that motor operator operating temperature limit is 55☌, which becomes often the limitation.Ħ. Where can I get spare fuses for the motorized change-over switches?ĪBB factory does not provide spare fuses. Yes but deranting factors needs to be checked. For motorized change-over switches, ceiling mount is not recommended.ĥ. Can I use ABB motorized change-over switches in environments with temperatures higher than 40 degrees?

On table mount, horizontally and vertically. They will not work if they are on the left side.Ĥ. How can I mount the motorized change-over switch on the panel? 1. The motorized change-over stops operating after few operations.Ĭheck that you are supplying the motor operator with correct voltage level and that control circuit connections are voltage free.Ģ. Motor operator does not react to control command.Ĭheck that the fuse of the motor operator (at the bottom of the switch) is ok, that the handle is not mounted, that no padloks are installed and that the Auto/ Manual toggle is in AUTO mode.ģ. The auxilary contacts do not connect when the switch poles are moving.Ĭheck that auxiliary contacts are installed on the right side of the motorized change-over switch.
