Minimum of measured values for operation timeĪverage of operation time at such voltage as maximizes deviation from TM in allowable voltage range.Īverage of operation time at such temperature as maximizes deviation from TM in allowable temperature range.Īverage of operation time at such halt time (in the range from the specified recovery time to 1 hour) as maximizes deviation from TM.
Maximum of measured values for operation time The time will be approximately some number K T K R C, but K may not be exactly 1, depends on the MOSFET, supply voltage and relay characteristics. The uninterruptible power supply delay timer (QUPSDLYTIM) controls the length of time that the system waits before saving main storage and powering down the. For digital timers, any arbitrary scale-value may be used. The resistance is 15K 100K or 15K100K/ (15K+100K) 13K. Other types include interval-on-operate, flasher, and repeat cycle timers. A time delay relay may be used for event sequencing, instrumentation control, in an alarm circuit or watchdog circuit. The measurement may be performed in other specified temperature ranges.Īverage of measured values for operation time On- and off-delay timers represent the most typical time delay relay timers in use. The measurement may be performed in other specified voltage ranges. If no question arises from evaluation results, 13-35☌ is acceptable. Then, reset the range to 10 hours, leaving the pointer set at the graduation as it is.įluctuation range of allowable voltage of power supply Note 3įor digital timers, the set value Ts shall be optional. For example, if you want to set 8 hours in the range of 10 hours, first set the pointer to such a graduation where the actual operating time should become as close to 8 seconds as possible in the range of 10 seconds. When using an analog type multi-range timer for setting of long time, the setting procedure stated as follows minimizes the error. Select a digital timer for the case when accuracy is required. As far as the set error is concerned, digital timer is by far exact. At the end of the time delay, the relay coil is energized. Even though the names may differ, the functionality is the same: Upon application of the input signal, the time delay begins. The error produced when 10 hours is set is also equivalent to an error of maximum ±5 hours. Relays with the DOM functionality may also be referred to as On Delay or Delay on Operate. If the set error is ±5%, it becomes equivalent to an error of maximum ±5 hours on the assumption that 100 hours is set in the range of 100 hours. The set error of an analog timer is the rate to the maximum scale value.
It means the difference between the set time and the time which actually elapses.
