(3) When contact conditions are verified, as shown in figure 13-2, start variable drive and gradually increase speed, with ohmmeter connected to pins B and A. At a speed of 290 rpm's per minute, the ohmmeter should indicate that contact A and B opens. Hold the variable speed drive at that speed and transfer the ohmmeter leads to pins A and C. The ohmmeter should indicate a closed contact. (4) Leave the ohmmeter leads connected to pins A and C and gradually reduce speed. In the range of 190 to 210 rpm, the contacts of element S9-1 should reset to the condition illustrated in figure 13-2. To verify operation of element S9-1 contacts A and C, increase 13-2
