6 ON-DELAY TIMER BASIC CIRCUIT 1. Delay Operation (Instantaneous input) When control switch A is pressed, timer T starts immediately and after t-time elapses, load L is turned ON. When B is pressed, timer T is reset and load L is turned OFF. 4. Fixed Time Operation (Continuous input) When switch A is closed, load L is turned ON and after t-time elapses, the load is turned OFF. When switch A is opened, timer T is reset and load L is turned OFF. 5. Delay Reset Operation When contact A is reversed, load L is immediately turned ON. When contact A is returned to normal state, load L is turned...

8 • Pause time error It means the difference between the operating time to a fixed pause time and the operating time to a pause time that varies. The pause time characteristics are the main characteristics of CR timer (timer exploiting charge and discharge of capacitor C and resistance R). If the oscillation count timer (timer which comprises an oscillation circuit composed of CR and quartz and is operated by a counting circuit inside IC or micro-computer which counts the reference signal) is used, the pause time error becomes almost negligible owing to its principles of operation....

9 GENERAL APPLICATION GUIDELINES CAUTIONS FOR CIRCUITS 1. Protective circuit for timer contact In the circuit that switches an inductive load, a contact failure may occur at a contact point due to surge or inrush current resulting from that switching. Therefore, it is recommended that the following protective circuit be used to protect the contact point. 2. Type of Load and Inrush Current The type of load and its inrush current characteristics, together with the switching frequency are important factors which cause contact welding. Particularly for loads with inrush currents, measure the...

10 2) If the timer is directly switched with a non-contact element, leak current may flow into the timer and cause it to malfunction. 6. Power off time If the operation voltage for the timer is turned ON after the limit time operation is completed or before the limit time is reached, the Power off time longer than the timer restoration time must be secured. 7. Suicide circuit If the timer is restored immediately after the specified time is reached, the circuit must be configured so that the restoration time of the timer can be secured sufficiently. If the power circuit for the timer is...

11 7. Operating environment 1) Use the timer within the ambient temperature range from –10°C to +50°C +14°F to +122°F (+55°C +131°F for the LT4H series) and at ambient humidity of 85% RH maximum. 2) Avoid using the timer in a location where (a) inflammable or corrosive gas is generated, (b) the timer is exposed to much dust and other foreign matter; (c) water or oil is splashed on the timer; or (d) vibrations or shocks are given to the timer. 3) The timer cover (case), the knobs, and the dials are made of polycarbonated resin. Therefore, prevent the timer from being exposed to organic...
