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").
