Access guarding
WARNING . . . AUTOMATIC START/RESTART
When the AG4 Scanner is configured for Automatic Start/Restart operation, the sensor will turn its safety outputs on as soon
as the protective field is clear. If the application
requires
a manual start/restart signal then the Start/restart Interlock function
must
be configured for this
manual Start/restart signal
.
Failure to do so could cause a machine to operate in an unexpected way at power-up or after temporary power
interruptions.
WARNING . . . SCANNER OPERATION ON POWER-UP
It is the responsibility of the person who configures, installs, and/or maintains the AG4 to assess what safeguarding devices
and methods are appropriate for any given machine or application and to be aware that the power-up behavior of this Scanner
application may not be obvious to the machine operator.
WARNING . . . START/RESTART (RESET) PUSH BUTTON LOCATION
The system Start/restart (Reset) push button must be accessible only from outside, and in full view of, the
hazardous area. Reset switches must also be out of reach from within the safeguarded space, and must be protected
against unauthorized or inadvertent operation
(via rings, guards, key or other means). If any areas are not visible from the
reset switch, additional means of safeguarding must be provided.
Failure to do so could result in serious bodily injury or
death.
WARNING . . . FIELD PAIR SWITCHING LIMITATIONS
Field Pair switchover (safety output authority changes) are only permitted during portions of application cycle where hazards
are not present or are otherwise inaccessible via other guarding means.
Failure to properly control or apply Field Pair switchover operations can result in serious bodily injury or death
.
WARNING . . . FIELD PAIR SWITCHOVER CONTROL STATE 8
Field Pair switchover logic control state 8 deactivates the entire Protective Field monitoring function of the Scanner. This
creates a condition where the Scanner safety outputs
(OSSDs) are turned ON
even if a person enters the potentially
hazardous area.
Only use Field Pair switchover state 8 when there is no
hazard exposure
for personnel.
Never
start the Scanner with switchover state 8 active.
Failure to follow these recommendations can potentially create a dangerous condition that may lead to serious injury
or death.
