Shadow 8 User Manual

Operation
Illuminated IBIs also identify the beams programmed as a fixed blanking window whenever
the amber Blanking Active LED is lit. 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.
Selected IBIs 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 IBIs 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 documented, including suggested remedies for each fault, in Chapter 4 of this
manual (see Troubleshooting with Fault Codes, page 4-1).
The green Power LED indicator on the cover of the optional control box is illuminated when
power is being applied to the control. The two green safety relay LEDs, labelled “OSSD 1”
and “OSSD 2,” are illuminated when the safety relays are “closed,” or energized. When the
safety relays are “open,” or de-energized, these two LEDs turn off.
Shadow 8 Operating States
Shadow 8 can be in one of five operating states, which are specified by the LED indicators on
the Main Receiver:
•
Machine Run
The Machine Run/Stop LED is illuminated green, the two safety relays are “on,” and the
auxiliary output is in a state consistent with its configuration. The protected machine is
allowed to operate. Turning the Program/Run/Start key switch to START has no effect.
•
Machine Stop
The Machine Run/Stop LED is illuminated red, the two safety relays are “off,” and the
auxiliary output is in a state consistent with its configuration. The protected machine is not
allowed to operate.
•
Interlock
The Machine Run/Stop LED is illuminated red, the yellow Interlock/Alarm LED is lit, the
two safety relays are “off,” and the auxiliary output is in a state consistent with its
configuration. The Interlock state can only be cleared when the sensing field is free of
obstructions and the Program/Run/Start key switch is turned to the START position.
•
Alarm
The Machine Run/Stop LED is illuminated red, the yellow Interlock/Alarm LED is
flashing, the two safety relays are “off,” and the auxiliary output is “off.” The Alarm state
can only be cleared when the problem that caused the alarm is corrected and either power is
recycled to Shadow 8 or the Program/Run/Start key switch is turned to the START position.
•
Blanking Fixture Removed
The amber Blanking Active LED is lit, the Machine Run/Stop LED is illuminated red, the
two safety relays are “off,” and the auxiliary output is in a state consistent with its
configuration. The protected machine is not allowed to operate. To clear this state, replace
the fixture in its original position, which is defined by a consecutive string of illuminated
IBIs, or program a new blanking window with a different object or no object.
