(1) The circuit of one of the time relay controlled motor timing forward and reverse circuits is shown in Figure 3-67. The forward and reverse running times are controlled by time relays KTi and KTz respectively. Forward and
reverse operation are interlocked by the normally closed contacts of intermediate relays KAl and KAz.
