The series connection first counter-rotating relay K MR normally opened contact and counter-rotating indicator lamp HLR on the described counter-rotating indication loop;
Describedly just changeing on the control loop series connection and just changeing button SBF, interlock button SBT, counter-rotating relay K MR normally-closed contact and just changeing relay K MF, relay K MF normally opened contact is just being changeed in the described just commentaries on classics button SBF parallel connection of just changeing on the control loop second;
Series connection invert button SBR, interlock button SBT on the described counter-rotating control loop, just change relay K MF normally-closed contact and counter-rotating relay K MR, the second counter-rotating relay K MR normally opened contact in parallel of the invert button SBR on the described counter-rotating control loop.
Operation principle of the present utility model:
Operating personnel press just changes button SBF, is just changeing relay K MF energising work, and first is just changeing relay K MF normally opened contact closure, and it is bright just to change indicator lamp, thereby is just changeing the indication loop works; Second is just changeing relay K MF normally opened contact closure simultaneously, thereby is just changeing control loop work; Just changeing relay control is just changeing relay K MF normally-closed contact and is opening, thereby reverse turn control circuit is not worked;
Operating personnel press interlock button SBT, are just changeing the indication loop and just changeing control loop quitting work;
Operating personnel press invert button SBR, counter-rotating relay K MR energising work, and the first counter-rotating relay K MR normally opened contact closure, the counter-rotating indicator lamp is bright, thus counter-rotating indication loop works; While second counter-rotating relay K MR normally opened contact closure, thereby the work of counter-rotating control loop; Counter-rotating relay control counter-rotating relay K MR normally-closed contact closure is not worked thereby just changeing control circuit;
Operating personnel press interlock button SBT, and counter-rotating indication loop quits work with the counter-rotating control loop.
If operating personnel press scram button SJT, just changeing the indication loop, just changeing control loop, counter-rotating indication loop, counter-rotating control loop and quit work all.
