Timers - PAGE 6/20 - Basic technical concepts Operating principle A timer is an automation control component which is designed to energise an output contact during a precise timing cycle. It is also known as a “time delay relay”, “specified-time digital relay” or even an “electronic timer”. The timing cycle starts when either power is applied to the timer or with an initiate switch. The timer model determines whether an initiate switch is required. The delay on make time function in a Chronos 2 will begin as soon as the power is applied. With the series (TOP 948), an initiate switch is required. Initiate switches can also be either a maintained or impulse (momentary) type contact. Because of these options, there are a large number of potential timing functions and products.

Timers - PAGE 7/20 - Basic technical concepts Operating principle There are 4 types of timers are available: “DIN-rail mounted” products designed to be mounted to a standard 35 mm DIN-rail inside a wall-mounted or floor-standing enclosure. “Panel mounted” products designed to be mounted on the front of a control panel for easy access by the user. “Plug-in” products designed to be used with an industry standard 8 or 11 pin socket. The socket can mount on a DIN-rail or surface in an enclosure. “Surface mounted” products designed to be mounted to a surface inside a enclosure.

Timers - PAGE 8/20 - Basic technical concepts Operating principle Timing functions require a time reference to ensure the accuracy of products. This time reference is known as the “time base” The time base is obtained using one of two technologies: - Electromechanical: The time base is obtained from a synchronous micromotor whose speed depends solely on the frequency of the main supply on which it is connected. This motor, associated with a gearbox, controls contacts, usually microswitches. - Electronic: Several techniques are used: analogue or digital (counting) to obtain the time base. The output component is usually an electromechanical relay. Solid-state outputs are also possible.

Timers - PAGE 19/20 - Applications General Timer controls can be used in addition to a programmable controller (or PLC) or in places where a programmable controller is not necessary. The requirement can be as small as one input and one output. Two outputs are also available on some products. Combinations can also be used for more complex functions.

Timers - PAGE 22/20 - Cam timers Basic technical concepts Products The competition

Timers - PAGE 23/20 - Basic technical concepts Operating principle A CAM TIMER is an automation control component designed to actuate a series of contacts in a predetermined order during a cycle, according to a cyclical program. The cycle can be: single-shot, repetitive, or step-by-step. Often underrated, cam timers can be used to simplify automation systems considerably and eliminate the need for many components.

Timers - PAGE 24/20 - Basic technical concepts Operating principle Cam timers consist of: - A drive device: synchronous geared motor - Data carriers: standard, adjustable (programmable), or precut striker cams - Output switching components: microswitch (electrical) or microvalve (pneumatic) Standard Programmable Custom

Timers - PAGE 25/20 - Adapted products There are numerous possibilities when creating cam timers. - Switching possible with 1 to 40 circuits - Possibility of complex cycles with 2 motors - Assembly of microswitches and microvalves - Etc
