Zelio Timer Relays Page 18 Functions

18 Functions (continued) Function Tt: Retriggerable bistable relay with control signal on 1 output 2 outputs After energization of power supply and on energization of Y1, the output(s) R close(s) and starts the timing T. If the duration interval between 2 consecutive energization of Y1 is greater than the pre-set value T, the output(s) R will toggle from its/their present status at the end of the timing period. If the duration interval between 2 consecutive energization of Y1 is less than the pre-set value T, the output(s) R toggle from its/their present status as soon as Y1 energizes without completing T duration. The second output (R2) can be either timed (when set to "TIMED") or instantaneous (when set to "INST"). Function W: Interval relay with control signal off 1 output 2 outputs After power-up and opening of the control contact Y1, the output(s) R close(s) for a timing period T. At the end of this timing period the output(s) revert to its/their initial state. The second output (R2) can be either timed (when set to "TIMED") or instantaneous (when set to "INST"). 2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.). Function Wt: Interval relay with control signal off and with pause/summation control 1 output 2 outputs After power-up and opening of the control contact Y1, the output(s) R close(s) for a timing period T. Timing can be interrupted/ paused each time X1 energizes. When the cumulative total of time period elapsed reaches the pre-set value T, the output(s) R revert(s) to its/their initial state. The second output (R2) can be either timed (when set to "TIMED") or instantaneous (when set to "INST"). U Y1 R1 T tPrevious Page
