Patlite WDT-4LR-Z2 Instruction Manual page 53

◆ Maintain each of the signal tower's light off and light on states for 100 ms or longer. It is difficult to determine state
changes when they occur faster than 100 ms.
◆ When using normal determination and you need to change the input state of multiple signal towers at the same time,
the interval between these state changes need to be within 20 ms.
◆ When using normal determination and the input state of multiple signal towers change at different times, these state
changes should be longer than 100 ms of each other.
