Push-Button Procedure for Teaching a Single Sensing Set Point

(Complementary Outputs – Adjustable-Field Style)

The black wire conducts when the target is inside the programmed set point. The white

wire conducts when the target is outside (away from) the set point (see Figure 7).

1. Press and hold the Teach push button until the Teach LED turns Red (depress button

for approximately 2 seconds).

2. Position the target at the sensing set point. The Range LED should be green,

indicating a valid target. Briefly “click” the Teach push button. This will teach the

sensor the first limit. The Teach LED will flash red at 2 Hz to acknowledge receiving

the first window limit; it is now waiting for a second limit.

3. Maintain the same target position and “click” the Teach push button again to teach

the same window position. The Teach LED will return to either yellow or OFF as the

sensor returns to RUN mode.

Note: The yellow LED will follow the black wire output.

Remote Programming

A function is provided to program the sensor remotely or to disable/enable the push

button; this is accomplished via the gray wire. Disabling the push button prevents

anyone on the production floor from adjusting any of the programming settings.

Connect the gray wire of the Q50 Sensor to +5 to 30V dc, with a remote programming

switch connected between them. NOTE: The impedance of the remote teach input is 15

k

Ω.

To program, pulse the wire as illustrated in

Figure 6. NOTE: The duration of each pulse

(corresponding to a push button “click”) is

0.04 to 0.8 seconds.

Run Mode

NOTE: All LED indicators momentarily go

OFF when the sensor changes state

between RUN and TEACH modes.

Range LED

When the sensor detects a target within its

sensing range (either 100 to 300 mm for

visible-beam models, or 100 to 400 mm

for infrared beam models) the LED will be

solid green. In the absence of a target, the

Range LED is solid red. Refer to the

Indicator Status table on page 3.

Teach/Output LED

In RUN mode, the Output LED is yellow

when a target is sensed within the

programmed window limits; otherwise the

Output LED is red. Refer to the Indicator

Status table on page 3.

Complementary Discrete Outputs

The complementary discrete outputs are

either both NPN or both PNP. The outputs

are configured via the Teach procedure to

either a single window or a fixed-field

(single set point) application. The outputs

are short circuit-protected and can switch

up to 150 mA (resistive load).
