  1. Under IGN 2 switch ON & Wiper Int switch ON states, and wiper int volume value are acquired and intermittent time is calculated. then, wiper intermittent time is automatically converted.

    T1 : 0.7 ± 0.1s, T2 : INT Time (2.2 ± 0.2s ~ 10 ± 1s)

    *1 ON : IGN 2 = ON OFF: IGN 2 = OFF

  2. Wiper Control Precaution
    1. Variable int wiper
      1. Wiper low relay time is 0.7s ±0.1s.
      2. Intermittent time is from output ON to the next output ON.
      3. Wiper low relay output is continued for remaining ON time if INT switch is turned OFF during output.
      4. Intermittent time is restarted when IGN 2 switch is ON and wiper Int switch is changed from OFF to ON.
      5. Intermittent time is restarted when wiper int switch is ON and IGN 2 switch is changed from OFF to ON
      6. 2.5V is used when volume value is 2.5V or more.
