## @ TIMING CHARTS Each timer module is equipped with a NORMAL/REVERSE mode selector switch that provides greater flexibility in controlling the contact output state. In contrast to the Light-ON/Dark-ON mode selector switch that inverts the output state before the timing functions, the NORMAL/REVERSE mode selector switch inverts the output state after the timing functions. In the NORMAL mode, the contact output state coincides directly with the set times on the timer module. In the REVERSE mode, the contact output state is the same as an inverted NORMAL mode output state. ## E39-T1 ON-delay/OFF-delay/one-shot delay timer timer **==> picture [463 x 241] intentionally omitted <==** **----- Start of picture text -----**
