Example 1:

If two contacts for BACK-UP are required. Switch on SWR2-6 & SWR2-8, then
both CNR19 & CNR15 will close when the unit goes to back-up.

Example 2:

If one contact for OVL & FAULT is required. Switch on SWR2-2 & SWR2-3,
then the CNR15 will close when either OVL or FAULT condition happens. Of
course CNR17 will close when OVL happens and CNR13 will close when FAULT

happens.
