When disconnecting pins 5 and 7, the time period starts. At the end of set time period, the relay releases. Interconnection of pins 5 and 7 for at least 10 ms during the time period, causes the time to reset. No restart when time period has expired. Function 2 Like function 1, but with manual start. 2 Function 3 Interval timer - man. start man. restart - no time reset The relay operates and the time period starts when interconnecting pins 5 and 7 for at least 10 ms. At the end of set time period, the relay releases regardless of the connection between pins 5 and 7. Renewed connection between pins 5 and 7 causes the relay to operate and a new time period starts. Function 4 Delay on operate - man. start - no restart man. time reset The time period starts when disconnecting pins 5 and 7. At the end of the set time period, the relay operates. When interconnecting pins 5 and 7 for at least 10 ms during the time period, the time is reset and a new time period starts when pins 5 and 7 are disconnected. No restart when the time period has expired. Function 5 Delay on operate - man. start - man. restart - time reset Otherwise like function 4. Function 6 Delay on operate - man. start - man. restart - no time reset The time period starts when connecting pins 5 and 7. At the end of the set time period, the relay operates. When connecting pins 5 and 7 after the time period, the relay releases and a new time period starts. Specifications are subject to change without notice (25.10.99) S 1221 Mode of Operation (cont.) Function 7 Interval timer - aut. start no restart - man. time reset The relay operates and the time period starts when power supply is applied. At the end of the set time period, the relay releases. When interconnecting pins 5 and 7 for at least 10 ms during the time period, the time is reset and a new time period starts when pins 5 and 7 are disconnected. No restart when the time period has expired. Function 8 Like function 2, but with automatic start after applying power supply. Function 9 Like function 3, but with automatic start after applying power supply. Function 10 Delay on operate - aut. start - no restart - man. time reset The time period starts when power supply is applied. At the end of the set time period, the relay operates. When interconnecting pins 5 and 7 for at least 10 ms during the time period, the time is reset and a new time period starts when pins 5 and 7 are disconnected. No restart when the time period has expired. Function 11 Like function 5, but with automatic start after applying power supply. Function 12 Like function 6, but with automatic start after applying power supply. Function/Time Setting Selection of function DIP-switch selector (1 - 4).
