Operation

The TDR-F alows you to select between Off Delay and one Shot timing. The universal supply voltage accepts most typical control voltages

 

By selecting Off Delay with the function pot on the top, with supply voltage applied, when the Initiate Voltage or Contact are activated, the internal relay is energized. When the Initiate Voltage or Contact are de-activated, the internal relay remains energized and the timing begins. After the time delay, the internal relay de-energizes and the timing resets.

 

If the Initiate Voltage or Contact re-activate before the timing cycle is completed, the timing is reset. The timing will re-start when the Initiate Voltage or Contact is de-activated again.

 

By selecting One Shot with the function pot on the top, with supply voltage applied, when the Initiate Voltage or Contact is activated, the internal relay is energizes and the timing begins. After the time delay is completed, the internal relay de-energizes and the timing is reset.

 

Re-activating the Initiate Voltage or Contact during timing does not interrupt the timing cycle.
