Attaching Fiber Optic Cables to SU17 Series
1. Unlock the lever on the top of the amplifier. The
lever will spring open.
2. Insert a standard 2.2 mm diameter fiber optic
cable into the housing until the cable goes no
farther. For 1 mm diameter cables, insert fiber
ends into the adapter and then slide the adapter
into the sensor until it stops.
3. Turn the lever so that it locks. If the lever is not
locked, the spring will push it open.

SU17 Series Programming
Sensitivity Adjustment
The SU17 Series offers automatic sensitivity/hysteresis adjustment for the following
three distict applications:
• Contrast Sensing: for distinguishing 2 targets of different material, color, or
distance (2 teachings required)
• Position Sensing: for sensing the leading edge of a target
• Max. Sensitivity: for maximizing the thru scan sensitivity and scanning distance

Note 1
The SU17 sensor is preset in the «RUN», Light Operate «LO» and «Maximum
Sensitivity» before delivery.
Note 2
The alarm is locked on (output locked off) until the sensor is re-taught. The
«E» display indicates that the fiber optic/target is not positioned correctly.
Please confirm that the standoff distance and angle of the fiber optic is in
accordance with the fiber optic specification, then re-teach the SU17.

Off-Delay Timer
The 40 ms Off-Delay timer can be activated or de-activated by simply pushing the
tuning button for at least 10 seconds while in the «RUN» mode. A small dot on the
digital display will show when the timer is activated. See figure at right.

Margin Display
The digital display typically indicates the amount of light received. However, it can also show the contrast
margin if either of the following apply:
• The sensor is programmed for the distinction/contrast setting as shown on page 752.
•Press the “tuning” button while the switch is in the run mode. If the sensor is programmed for positioning, the
display will show “-“. If the sensor is programmed for maximum sensitivity, the display will show “H“.
The contrast margin shows the difference of light received between the two targets. The higher the number,
the better the security. In the example of above, the top row (margin level indication) shows the number in the
display, while the bottom row indicates the actual security margin expressed as a multiple of the automatically
adjusted hysteresis.
