4. Install proper transient suppression across the load to reduce the noise.
9.3.2 Check for Sources of Optical Noise
1. Turn off the emitter or completely block the emitter.
2. Use a Banner BT-1 Beam Tracker (see
on page 70 ) to check for light at the receiver.
3. Press the RCV button on the BT-1 and move it across the full length of the receiver’s sensing window. If the BT-1’s
indicator lights, check for emitted light from other sources (other safety light screens, grids or points, or standard
photoelectric sensors).
