Remote Programming and Push-Button Lockout
The remote line allows programming with a remote switch. It can also be used to lock
out the push button, preventing unwanted tampering with the push button. Connect
the white remote wire to 0V if not used.
• To disable the push button and the remote program wire, connect the white remote
wire to high supply potential (+V dc), then power the sensor ON.
• To program the sensor using the remote line, connect a normally open (N.O.) switch
between the white remote wire and high supply potential (+V dc), then power the
sensor ON. This enables remote programming.
• To enable the push button, turn the sensor power OFF, remove the white wire from
high supply, and then turn sensor power ON.
Quick-Set Programming
Quick-Set programming teaches the QL50 Sensor to respond to a specific
luminescence intensity and ignore less-intense luminescence conditions. The
programmed setting will be light operate; the sensor will respond to an equivalent or
more luminescent condition.
Sensing the luminescent target will close the normally-open output, turn the yellow
Output LED ON, and cause the output to conduct current (see Figure 2).
*The Yellow LED may be ON or OFF, depending on target and range.
**The Green LED may go OFF if a target is presented at the sensor threshold.
