Explanation of how the JCK timer has been requested.                     

Control power is applied continuously. When the initiating contact is closed, the output contacts change state. Opening the initiating contact begins the time delay. At the end of the time delay, the output contacts go back to original state. Reclosing the initiating contact during the timing will cause the timing to start over when initiating contact is reopened.
