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.
