Introduction 1-9
Shadow 8 LED Displays
Shadow 8 provides the following LED displays on the Main Receiver and Transmitter and on
the optional control to provide information about light curtain operation.
•
Three operating state LED indicators located on the pigtail end of the Main Receiver (see
Figure 1-1).
•
One status LED indicator located on the pigtail end of the Main Transmitter. When this
yellow LED is lit, wiring connections between the Main Transmitter and the Wintriss
Clutch/Brake control or Shadow 8 control are good.
•
Red Individual Beam Indicator (IBI) LEDs next to each phototransistor on the receiver.
•
Green power and safety relay LEDs on the cover of the optional control (see Figure 1-3).
Operating state LEDs provide the following information about Shadow 8 operation (see
Shadow 8 Operating States, below):
•
Machine Run/Stop (Green/Red) LED–When LED is green, light curtains are unobstructed.
When LED is red, light curtains are obstructed or Shadow 8 has experienced an internal
fault. The state of the yellow Interlock/Alarm LED (see next item) indicates which of these
conditions applies.
•
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 (see Programmable Fixed Blanking, page 1-11 and Floating
Blanking, page 1-11). Fixed blanking is enabled by default.
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 LEDs indicate either a penetration of the light curtain or receiver/transmitter
misalignment. When the required number of consecutive beams are not in alignment (see
Table 2-13, page 2-50), alternate IBIs on the misaligned receiver(s) illuminate. Detailed
instructions for using IBIs during alignment of Shadow 8 optic heads is provided starting on
page 2-49.
Selected IBIs on the Main Receiver also illuminate whenever there is a fault condition, which
is indicated by a continuously lit red Machine Run/Stop LED and a flashing Interlock/Alarm
LED. Each digit of the fault code is represented by a string of consecutively illuminated,
flashing IBIs. Each digit is separated by an unlit IBI and terminated by a string of unlit IBIs
(see Figure 4-1, page 4-2 for an example). Fault codes are fully documented, including
suggested remedies for each fault, in Chapter 4 of this manual.
When the amber Blanking Active LED is lit, indicating that programmable fixed blanking or
floating blanking has been enabled, illuminated IBIs identify beams that have been
programmed as a fixed blanking window. When the obstruction being blanked is present, the
Machine Run/Stop LED is lit green. When the obstruction is removed, the IBIs defining that
area of the light curtain remain lit, but the Machine Run/Stop LED turns red.
