C. Delay on Operate Mode
To put the TDR-1 into the "Delay on Operate Mode",
strap Trigger 2 to ground by wiring terminal 2 to terminal
3. Refer to the chart to the right to set the dip switches
for the desired delay time. Set JP2 to (-) side.
Note: See Operation section A. Trigger Inputs
(below) to set Trigger 1 polarity.
A. Trigger 1 Input
The Trigger 1 input can be set up to accept a contact closure to ground or to a positive/negative
going logic level voltage. The trigger may be a momentary pulse or continuous trigger. If the trigger
is held, it will not re-trigger the input until it has been cleared. Examples are shown below.
Momentary Positive Going Trigger.
Momentary Negative Going Trigger
or Push Button to Ground
Positive Trigger Held Continuous.
Negative Trigger or Push Button to
Ground Held Continuous
* Denotes Trigger Starting Point
B. Time Delay Relay Mode
When the TDR-1 receives a valid Trigger 1, the relay will activate for the programmed time. The
TDR-1 does not look at Trigger 1 again until the relay activation time is over.

C. Delay on Operate Mode
The TDR-1 mimics any closure it sees at trigger 1, delayed by the amount of time programmed
using the DIP switches as shown in Programming, section B.
