How it works:
When the power is turned on, the relay is turn off and waits for +12V to be received at the input. On receiving the +12V input, the relay turns on and waits for this voltage to drop. When +12V is drop from the input, the set time starts to run. After the time has elapsed, the relay turns off and remains ready (it waits again for +12V to be received at the input, and the cycle repeats).
The relay has two modes. They are determined by jumper W2.
- W2 - closed: In this mode, when the relay is activated (ie +12V received at the input and drop), no matter how many times +12V will be received at the input and drop, the set time will run. After the time has elapsed, the relay turns off.
- W2 - open: In this mode, with the relay activated (i.e. +12V received at the input and drop), each time +12V occurs, the set time will be reset. The relay remains on and waits for +12V to drop to start running the set time. After the set time has elapsed, the relay is turned off.
LED indication for power is on and activated relay.
The time is set by a trimmer potentiometer (1 to 60 seconds or minutes).
Jumper to select seconds or minutes.
- W1 closed - secounds.
- W1 open - minutes.
Select seconds and adjusts the time. Then, if necessary, changes to minutes. The selection is performed at power off.
