Remote Programming
To remotely program the TEACH and OUTPUT CONFIGURATION modes, connect the
sensor’s gray wire to a remote programming switch. (This input parallels the push
button on the sensor, so the push button sequences explained on the previous two
pages also apply for a remote switch.)
Connect a remote programming switch between the gray wire and dc common (see
hookup diagrams on page 6). The switch may be either a normally open contact, or
an open-collector NPN transistor.
The timing diagrams (Figure 5, below) define single-, double-, and triple-click,
simulating the D12 Expert’s programming push button. The ON time of each click
must be at least 40 milliseconds. The minimum space between clicks must be at least
40 milliseconds. The total time of two adjacent clicks of a double- or triple-click must
be less than 800 milliseconds. Conversely, there must be at least 800 milliseconds
between the start of a single- or double-click and the next input.
