When power supply is interrupted, the time period starts and at the end of the set time period, the relay releases. If power supply is reapplied before the relay releases, the time is reset and the relay remains on. Note: The S 105 should not be operated by pulses shorter than 200 ms. For this purpose the relay S 103, operated by means of an external contact function, should be used.
