Timer Function


	Timer Function / Mode of Operation
	Your choices are...
	ON-delay		Also called Delay on Make, Delay on Operate, Operate Delay, Prepurge Delay and Delay on Energization. The time delay begins after application of power. At the end of the time delay the contacts open or close. If the contact is normally open (NO) the load energizes at the end of the time delay. If the contact is normally closed (NC) the load de-energizes after the time delay. The time delay and output are reset by removing power.
	OFF-delay		Also called Delay on Break, Release Delay, Delay on Release, Postpurge Delay and Delay on De-Energization. The timer contacts open or close immediately after power is removed. The preset time delay must elapse before the contacts return to normal position and the load is de-energized. Power must be applied before and during timing. Re-closing the control switch during the timing resets the time delay. Most reset on loss of power.
	One-shot		Also called One Shot Relay, Single Shot, Single Shot Interval, Single Pulse, Latching Relay, Latching Off Delay and Latching Delay on De-Energization. Contacts change position immediately upon application of power and remain in changed position for the preset time delay. After the time delay, the contacts return to their normal position. Power must be applied before and during timing. Reset occurs when the time delay is completed and the control switch is opened.
	Interval		Also called Interval On, On Interval, Pulse Shaping, Bypass Timing, Interval Delay and Delay on Energization with Instantaneous Transfer. Time delay begins when power is applied. The output is energized during time delay and de-energizes at the end of the time delay, and it remains de-energized until power is removed. The time delay and output are reset by removing power.
	Recycle		Also called Recycle Timing, Duty Cycling, Cycle, Repeat Cycle, Delay on Operate and on Release, On/Off Dual Delay, Flasher and Dual-Delay Energization. Timing function starts with closing of control switch. The load alternately turns ON and OFF at regular intervals until power is removed. The time delay is reset by removing power.
	Time Indicator		Records and displays elapsed time but performs no output function.
	Counter		Timer can be programmed to function as a counter as well as timing functions.
	Other		Other unlisted, specialized, or proprietary configuration.

	Pole and Throw Specifications
	Your choices are...
	Single Pole, Single Throw (SPST)		A switch that makes or breaks the connection of a single conductor in a single branch circuit. This switch typically has two terminals. It is commonly referred to as a "Single-Pole" Switch.
	Single Pole, Double Throw (SPDT)		A switch that makes or breaks the connection of a single conductor with either of two other single conductors. This switch typically has 3 terminals, and is commonly used in pairs and called a "Three-Way" switch.
	Double Pole, Single Throw (DPST)		A switch that makes or breaks the connection of two circuit conductors in a single branch circuit. This switch typically has four terminals.
	Double Pole, Double Throw (DPDT)		A switch that makes or breaks the connection of two conductors to two separate circuits. This switch typically has six terminals and is available in both momentary and maintained contact versions.
