9.6 Check for Sources of Electrical and Optical Noise
The SX5 is designed and manufactured to be highly resistant to electrical and optical noise and to operate reliably in
industrial settings. However, serious electrical and/or optical noise may cause a random OFF state of the OSSDs. In very
extreme electrical noise cases, a Lockout is possible.
Do not directly ground the SX5 housing. Make only those connections as described in this document.
All SX5 wiring is low voltage. Running these wires alongside power wires, motor/servo wires, or other high-voltage wiring
can inject noise into the SX5. It is good wiring practice (and may be required by code) to isolate SX5 wires from high-
voltage wires. The Banner model BT-1 Beam Tracker (see Banner catalog or website) is a very good tool for detecting
electrical noise. It can be used to detect electrical transient spikes and surges.
If random nuisance noise problems occur:
1. Check for optical interference from adjacent safety laser scanners or other photoelectric sensors.
a) Turn off the Scanner.
b) Use a Banner BT-1 Beam Tracker to check for light at the SX5 front screen (window) by press the RCV button on
the BT-1 and moving across the full length of the window with the BT-1 lenses facing away from the SX5.
c) If the BT-1’s indicator lights up, check for light from other sources (e.g., other safety laser scanners) by tracking
down the emitted light using the BT-1.
2. Check for sources of electrical noise.
a) Turn off the Scanner.
b) Cover the lens of the BT-1 with electrical tape to block optical light from getting into the receiver lens.
c) Press the RCV button on the BT-1 and position the Beam Tracker on the wires going to the Scanner or any other
nearby wires.
d) To reduce or eliminate noise caused by the switching of inductive loads, install proper transient suppression
across the load.
