Frequently asked questions

1. The motorized change-over stops operating after few operations.
Check that you are supplying the motor operator with correct voltage level and that control circuit connections are voltage free.

2. Motor operator does not react to control command.
Check 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.

3. The auxilary contacts do not connect when the switch poles are moving.
Check that auxiliary contacts are installed on the right side of the motorized change-over switch. They will not work if they are on the left side.

4. How can I mount the motorized change-over switch on the panel?
On table mount, horizontally and vertically. For motorized change-over switches, ceiling mount is not recommended.

5. Can I use ABB motorized change-over switches in environments with temperatures higher than 40 degrees?
Yes but deranting factors needs to be checked. Notice that motor operator operating temperature limit is 55°C, which becomes often the limitation.

6. Where can I get spare fuses for the motorized change-over switches?
ABB factory does not provide spare fuses. You can use any brand that meets the requirements specified in the catalog.

7. I have ordered an OMD controller as a spare part and after doing the connection correctly the product does not work as it should.
Check the operating mode of the OMD controller. Select Motorized OTM_C option when connecting separate OMD controller and OTM motorized change-over switch.

8. Can the OMD200 controller be used in a 3 phase system?
The OMD200 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.

9. Can the OMD300 controller be used in 3 phase system?
The OMD300 controller does not work without neutral line. This means that you need to get it from a separate place and select the option "Neutral in use" from the OMD controller. If this is not done, the power source to motor does not work.

10. OMD controller shows an alarm. What do I need to do?
First, 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. After the alarm has been shut off, the controller is in manual mode and you need to push AUTO button once.

11. What are recommended accessories when ordering OTM40…125 + OMD controller as two separate components?
We recommend to order a controller, a motorized change-over switch and 3 sets of OZXT6 terminal clamp sets.

12. What are recommended accessories when ordering OTM160…3200 + OMD controller as two separate components?
We recommend to a controller, a motorized change-over switch, one set of OMZB_ voltage sensing connectors and 2 pieces of OA1G10 auxiliary contacts. For specific item types, refer to the technical catalog 1SCC303003C0201.

13. Are two pole change-over switches available?
For most of the switch products, ABB offers special two pole models.

14. Is it possible to use ABB change-over switches for DC applications?
Yes, ABB change-over switches can be used in DC application but notice that the electrical performance in DC is very different than in AC. To see the DC technical data, refer to the technical catalog 1SCC303003C0201.

15. The product locking information output feature in the OTM does not work.
The locking infromation output feature in the OTM does not work if the motor operarator is not supplied.

16. The Automatic Transfer Switch does not change its position even if both networks are available.
Check that the fuse of the motor operator (at the bottom of the switch) is ok, that the OMD controller does not show any alarms and that the switch has a power supply.

17. In motorized change-over switches from 40 to 125 Amperes (OTM40….125): How does the connection terminal with the mark "this terminal is for OMD connection" works?
That terminal can be used only when connecting ABB OMD controllers to the motorized change-over switch. When using another type controllers, connection (C-II-I-0) must be used.

18. Can I use an external handle and shaft with a motorized change-over switch or automatic transfer switch?
No. It is only allowed to use the direct mount handle (emergency handle) to operate switch manually.

19. What is the transfer time of the Automatic Transfer Switches?
The OFF time range is of 0,4 - 1,5 seconds. The total transfer time range is 2 -6 seconds. To find product specific operating times, refer to the user manual.

20. I have ordered a pre-wired ATS solution with voltage sensing on top. Can I change the voltage sensing cables to bottom?
No. The voltage sensing cables are installed inside switch body and cannot be removed or changed. The only possibility is to do completely new wiring.
