11 Functions (continued) Zelio Timer Relays Functions (continued) Function Aw: Power on-delay with retrigger/restart control 1 output 2 outputs The timing period T starts on energization. At the end of the timing period T, the output(s) R closes. Closing of the control contact Y1 makes the output R open. Opening of control contact Y1 restarts timing period T. At the end of the timing period T, the output(s) R close(s). The second output (R2) can be either timed (when set to "TIMED") or instantaneous (when set to "INST"). Function B: Interval relay with control signal 1 output 2 outputs After power-up, pulsing or maintaining control contact Y1 starts the timing T. The output R closes for the duration of the timing period T then reverts to its initial state. The second output (R2) can be either timed (when set to "TIMED") or instantaneous (when set to "INST"). Function Bw: Double interval relay with control signal 1 output 2 outputs After power-up, transition of Y1 (either from energization to de-energization or vice-versa) will cause the output(s) R to close(s) for the duration of the timing period T and then 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"). Function C: Off-delay relay with control signal 1 output 2 outputs After power-up and closing of the control contact Y1, the output R closes. When control contact Y1 re-opens, timing T starts. At the end of the timing period, 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"). 2 timed outputs (R1/R2) or 1 timed output (R1) and 1 instantaneous output (R2 inst.). Function Ct : Off-delay relay with control signal and with pause/summation control After power-up and energization of Y1 the output(s) R close(s). When Y1 de-energizes, timing starts and can be interrupted/paused each time X1 energizes. When the cumulative total of time periods 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"). R1 Y1 U T U Y1 R1 T R1 Y1 U R2 R2 inst. T U Y1 R1 T R1 Y1 U R2 R2 inst.
