Shadow 8 LED Displays
Shadow 8 has LED displays on Main and Extension Receivers and on the optional control box
to provide information about light curtain operation. There are four types of LED displays:
•
Three operating state LEDs located on the pigtail end of the Main Receiver (see Figure 1-1,
page 1-3)
•
One status LED indicator located on the pigtail end of the Main Transmitter
•
Individual Beam Indicator (IBI) LEDs next to each phototransistor on the receiver
•
Power and safety relay LEDs on the cover of the optional control box (see Figure 1-3,
page 1-5)
Operating state LEDs on the Main Receiver provide the following information about Shadow
8 operation (see Shadow 8 Operating States, page 3-2):
•
Machine Run/Stop (Green/Red) LED–When LED is green, light curtains are unobstructed,
and both safety relays are “closed” (or energized). When LED is red, light curtains are
obstructed, Shadow 8 has experienced an internal fault, optic heads are misaligned, or the
control has not been re-started after an Interlock or Alarm state. Both safety relays are
“open” (or de-energized). The state of the Interlock/Alarm LED (see next item) indicates
the cause of the red Machine Run/Stop LED.
•
Interlock/Alarm (Yellow) LED–Light curtains are obstructed (LED lit continuously) or
Shadow 8 has experienced an internal fault (LED flashing).
•
Blanking Active (Amber) LED–Programmable fixed blanking and/or floating blanking
feature has been enabled. Fixed blanking is enabled by default.
The status LED indicator on the Main Transmitter, which is yellow, is lit when wiring
connections between the Main Transmitter and Wintriss Clutch/Brake control or optional
Shadow 8 control are good.
The red Individual Beam Indicator LED next to each phototransistor on the receiver becomes
lit whenever the light pulse from the corresponding beam on the transmitter is not detected.
These Individual Beam Indicators signal either a penetration of the light curtain or receiver/
transmitter misalignment. Alternate IBIs illuminate on a misaligned receiver when the
required number of consecutive beams are not aligned (see Table 2-13, page 2-50) or are
interrupted by a fixed blanking window (see Table 3-1, page 3-6). Instructions for using IBIs
to help align Shadow 8 optic heads is provided starting on page 2-49.
