Cycle timing controller 1

The cycle timing control circuit is composed of the digital delay relays KTl-KT5, time relay KT6 and AC contactors KMl-KM4, and it is shown in Figure 3-89. KTl-KW are used to control the conduction time of 4-way timing control circuit. KT5 (the set time is 4 hours, which is the total of 4-way conduction time) is used to reset KTl-KW and make them work in cycle; KT6 provides for the KT5 reset conditions. KTl-KT5 use the JSl4S digital delay relays; KT6 uses JSl4 time relay. KMl-KM4 select the 220V AC power relay.
