General Information Timers TIMer-reLATeD TerMInOLOGy • what is a timer? The timer is a relay having such an output (with or without contact) which electrically closes (turns ON) or opens (turns OFF) the circuit after a preset time elapses when electrical or mechanical input is given. • On-delay Operation (Time delay operation) The on-delay operation is an operation to give output when preset time expires after a predetermined input is given to the power supply circuit or input circuit. On-delay operation includes power supply on-delay operation and signal ondelay operation. Example of power...

• 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....

General Information Timers 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. Application AC DC (see note.) Available r c Diode Available Available If the load is a relay or solenoid, the release time lengthens. Effective when connected to both contacts if the power supply voltage is 24 or 48...

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 turned...

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 inflammable or corrosive gas is generated, the timer is exposed to much dust and other foreign matter water or oil is splashed on the timer or 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 solvents such as methyl...
