If the supply voltage is correct, Test1 is 10 V dc to 30 V dc, and the emitter does not operate properly (RUN
mode with beam scanning), replace the emitter.
If the voltage is less than 3 V dc, the emitter should be in Test mode and no scanning should be occurring. If the
emitter is not in Test mode, replace the emitter.
The EZ-SCREEN SLS is designed and manufactured to be highly resistant to electrical and optical noise and to operate reli-
ably in industrial settings. However, serious electrical and/or optical noise may cause a random Trip. In very extreme electri-
cal noise cases, a Lockout is possible. To minimize the effects of transitory noise, the
EZ-SCREEN SLS responds to noise
only if the noise is detected on multiple consecutive scans.
If random nuisance Trips or lockouts occur, check the following:
Poor connection between the sensor and earth ground
Optical interference from adjacent light screens or other photoelectric sensors
Sensor input or output wires routed too close to noisy wiring
It is important that the light screen sensors have a good earth ground. Without this, the System can act like an antenna and
random Trips and Lockouts can occur.
All EZ-SCREEN SLS wiring is low voltage; running these wires alongside power wires, motor/servo wires, or other high-volt-
age wiring can inject noise into the EZ-SCREEN SLS System. It is good wiring practice (and may be required by code) to iso-
late EZ-SCREEN SLS wires from high-voltage wires.
Follow these steps to check for optical noise sources.
Electrical and Optical Noise
9.4
Check for Sources of Electrical Noise
9.4.1
Use the Banner model BT-1 Beam Tracker Alignment Aid (see " Alignment Aids " on page 101 ) to detect electrical
transient spikes and surges.
1.
Cover the lens of the BT-1 with electrical tape to block optical light from entering the receiver lens.
2.
Press the RCV button on the BT-1 and position the Beam Tracker on the wires going to the EZ-SCREEN SLS or any
other nearby wires.
3.
Install proper transient suppression across the load to reduce the noise.
4.
Check for Optical Noise Sources
9.4.2
Turn off the emitter, completely block the emitter, or open the Test input.
1.
Use a Banner BT-1 Beam Tracker (see " Alignment Aids " on page 101 ) to check for light at the receiver.
2.
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 in-
dicator lights, check for emitted light from other sources (other safety light screens, grids or points, or standard photo-
electric sensors).
