7.2 TARGETS 7 COMMANDS AND TARGETS
Severity: This self-test error does not directly inhibit protection. However, some or all of the affected Brick inputs/outputs
may not be available to the UR-series device.
If this message appears, check the Brick environment for over/under temperatures and the voltage of its power source. If
the ambient temperature and supply voltage are within Brick specifications, consult the factory. Troubles resulting from a
Brick output failing to respond to an output command can only be detected while the command is active, and so in this case
the target is latched. A latched target can be unlatched by pressing the faceplate reset key if the command has ended,
however the output may still be non-functional.
