ABB 70BV01c-ES HESG447260R1 Switch output module

The cam you select determines the operation of all contact blocks mounted to the operator. It is selected on the basis that it provides the simplest circuitry for the desired “X-O” diagram. The selection tables of the following page show all the “X-O” combinations. For the purpose of this example, the applicable portion of those tables is shown in Table 47-204.

It becomes immediately obvious that cam 3 is the better choice for two reasons, (1) the series combination can be avoided making it simpler to wire, (2) only two contacts are required, which is less expensive than the three contacts required by cam 2.

Contact Block Selection. 

Having selected the cam, contact block selection is simply a matter of gathering the A position and B position circuits into pairs which make up the most convenient contact block arrangement. If there is an imbalance in the number of circuits under A or B, then single circuit blocks must be selected for these leftover circuits

Selector Switch Operator. 

Lastly, you have to choose from the many types of operators — knob and lever in various colors or keyed. Also what combinations of maintained and spring return functions are required. Selection of these operators can be found on Page 47-135. For the above example you may want a 3-position maintained black knob, cam 3 — Catalog Number 10250T1323.Circuits shown illustrate connections to obtain a selector switch circuit combination and are shown with their appropriate line diagrams. Field wiring of jumper connections required as shown.
