Adjustment of the time delay
- Select the timing range value immediately greater than the time required using selector switch 2.
Example: required time 12 s; range selected 30 s.
- Using potentiometer

On-delay adjustment (ta).
Off-delay adjustment (tr).
Switch for converting the second changeover contct to instantaneous mode (RE7-MA13BU).
LEDs, depending on the model :
- Green LED: flashes during the time delay period, permanently on outside the time delay period
- Yellow LED 1: on when the 1
- Yellow LED 2: on when the 2
