Independent settings of T1 and T2 intervals. it is lit for 80% of the time, and off for 20% of the time. For the T2 time, the period is 250 ms. Adjustment of the set values: the values of time and range are read in the course of the relays operation. The set values may be modifi ed function EWu at any moment. Release: the relay is released with the supply voltage. For DC supply, the positive pole must be connected to the A1 line. The level of the S contact When the control contact S is open, application of the supply voltage U activation is adjusted automatically depending on the supply voltage. starts operation in the EWu function - the interval T1, and after the interval T1 has lapsed, the output relay switches on for the interval T2. Supply: the relay may be supplied with DC voltage or AC voltage 48...63 Hz of 10,8...250 V. A programmed control of the supply voltage has been applied so the processor shall not start operation if the voltage is lower than approximately 10 V. The supply voltage is permanently function NWu monitored in course of the operation of the relay. When the voltage drops below 9 V for more than 50 ms, the relay shall be reset. Owing to this, the regeneration time is programmed to 50 ms, and it does not depend on the tolerance of the elements. When the control contact S is closed, application of the supply voltage U starts operation in the NWu function - from switching on the output relay R for the interval T1, and after the interval T1 has lapsed, the output relay switches off for the interval T2, and following the interval T2, the output relay R switches on for continuous time. In the course of the relay operation, closing of the control contact S at any time will cause reset and the operation in the NWu function will start whereas opening of the control contact S at any time will cause reset and U - supply voltage R - output state of the relay the operation in the EWu function will start.
