Control and function description:

LED indicators: ON (red LED) = relay is connected to the power supply, OUT (green LED) = lights up: output relay is switched on (contacts 2-3 connected), OUT (green LED) = flashes: time counting down to switch-on.

Rotary potentiometer "t" for the value range 0.1 (1%) to 10 (10=100%).

Rotary potentiometer for the maximum time value "TS": A=10s, B=100s, C=10min., D=100min., E=10hr., F=100hr.

The relay enables delayed switching ON of the NO contact (terminals 2-3) after switching on the power supply (without control signal).

Switching function. Changing the time by turning the dial will be reflected in the next power-up. The output relay contains a changeover contact SPDT, terminal 2=COM, terminal 3=NO, terminal 1=NC.

1/ Switch-on time (terminals 2 - 3):

- Delay ON after power connection (no control signal).

- after connecting to the power supply, the set time (t) starts to count and after the time has elapsed, the output relay (RLY) is switched on (connects terminals 2 - 3).

2/ Using the NC contact as an OFF delay (terminals 2-1).

- Terminals 2 - 1 also switch off in the absence of power supply.

- When power is connected, the set time starts counting, after which the output relay switches on and disconnects terminals 1-2.
