TIMER CONTACT POSITIONS

Introduction

The purpose of the timer sequence (Esterline) chart is to indicate the position of the timer contacts

during the different events of the cycles. This chart indicates the path of current flow through the

appliance at any given time. In order to interpret the timer sequence chart, it is important to understand

how it interacts with a wiring diagram.

Switch Positions

A solid black bar means that the switch is closed. No bar, or a white space, means that the switch is

open. A switch can be open or closed for part of an interval. This is indicated by a black bar for only

part of the interval space. An X means that at that point in the timer, the switch could either be open or

closed. This typically happens when a switch is either about to open or close, but since it takes some

time for that action to occur, the switch position cannot be predicted at that time.
