| Option 1 | The relay will operate for the preset time as soon as a trigger signal is present. It will not operate again until the trigger signal is removed and re applied. This option is as supplied. |
| Option 2 | The relay will not operate until after the preset time and only if the trigger signal remains during the timing period, once operated the relay will remain active until the trigger signal is no longer present. This option is selected by CUTTING LINK 1. |
| Timing | Two timing ranges are available 0.25s to 15s selected by leaving as supplied and 2s to 3.5mins selected by CUTTING LINK 2. Adjustment within these ranges is via a potentiometer P1. |
| Inputs | Two types of input are catered for. A clean contact input (e.g. door contacts or push buttons) and a voltage input (9 to 28V DC or 7 to 20V AC). These inputs can be selected to trigger normally open or normally closed. To trigger the timer if the input is shorted or a voltage is applied (normally open) leave LINK 3 UNCUT. To have timer trigger if the input is opened or the voltage is removed (normally closed) then CUT LINK 3. With normally closed operation only one of the inputs can be used. |
