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

B1
= ––––––
Potentiometer for fine adjustment of the time delay, graduated in % of range max. setting 2.
10-position timing range selector :
0.05…1 s
0.15…3 s
Switch for converting the second changeover contact to instantaneous mode (RE7-PP13BU and PD13BU).
LEDs, depending on the model:
- Green LED: flashes during the time delay period (except for the first 2 timing ranges), permanently on
- Yellow LED 1: on when 1
- Yellow LED 2: on when 2
