3. Press the RCV button on the BT-1 and position the Beam Tracker on the wires going to the S4B or any other nearby
wires.
4. If the BT-1's indicator lights, check for sources of electrical noise and separate the S4B cordset from any high-voltage
wiring, if applicable.
5. Install proper transient suppression across the load to reduce the noise.
8.3.2 Check for Sources of Optical Noise
1. Turn off the emitter or completely block the emitter.
2. Press the RCV button on the Banner BT-1 Beam Tracker Alignment Aid and move it across the full length of the
receiver’s sensing window to check for light at the receiver.
3. 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).
