All sequence functions can also be inplemented by utilizing the SLAVE input. This
can be done by either a mechanical switch or the electronic switch in conjunction with
a sensing plate as shown in Figure 6. When the plate is touched, a logic high level is
generated at the EXTENSION terminal for both half cycles of the line frequency.
