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.

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
