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

Potentiometer for fine adjustment of the time delay in % of range max. setting 2.
10-position timing range selector :
0.05…1 s
0.15…3 s
Adjustable On-delay (ta).
Adjustable Off-delay (tr).
Switch for converting the second changeover contact to instantaneous mode (RE7-CP13BU).
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 1
- Yellow LED 2: on when 2
