The document provides an overview of timers, explaining their basic functions, types, and applications. It describes how timers operate using relay contacts that can be controlled to turn on or off at pre-set times, such as in lighting circuits and heating systems. The document also specifies various timer models, their voltage ranges, and relay contact configurations.

- 2. Timer Training Level 1 The basics
- 3. What is a Timer? A timer is in its most basic form is a set of relay contacts that can be set and controlled at pre-set times by the operator. This means that process can start and stop at a required time range to suit a particular application.
- 4. How does a timer work? A timer works by applying a supply voltage to the coil ( this must be specified by the user), the relay contacts will then turn on or stay off (depending on the function chosen) until the set time has elapsed, it will then turn off or on. It works in the same fashion as a normal relay, with the same contact configurations (SPDT, DPDT,3PDT,4PDT) but the contacts are time controlled.
- 5. Timer Functions On Delay = when voltage is applied to the timer the relay contacts do not change state (on/off) until the set time has elapsed. Off Delay = when voltage is applied to the timer the relay changes state (ON) immediately and stays on until the set time has elapsed.
- 6. Continued Flicker (Flasher) = when voltage is applied to the timer the relay contact will change state (ON) for the set time it will then turn off for the same set time and turn on again. It will repeat this process of ON and OFF until the voltage is removed from the timer.
- 7. Types of Timer Plug in = this is simply a timer that plugs in to a relay base. The pin configuration is the same as that of standard relays 8, 11 pin octal and 14 pin and can be used in the same bases. Din Rail Timers = a timer that clips on to DIN rail.
- 8. Where are timers used? Lighting circuits, where a button can be pushed once and the lights stay on for a certain amount of time then turn off. Used in flood lighting when people pay for One hour of pitch time for instance. Heating systems, when a room only Needs heating while people are present, This can be operated by a door switch. Water pumps, allowing a pump to run only For a certain amount of time.
