A lock-out relay is generally placed in line before or
after the e-stop switch so the power can be shut off at one
central location. This relay is powered by the same
electrical source as the control power and is operated by a
key lock switch. The relay itself may have up to 24 contact
points within the unit itself. This allows the control
power for multiple machines to be locked out by the turn of
a single key switch.

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
