Safety Relay PLC LEDs
LED/Key
Description
Blue
On indicates that the Safety Relay has power.
Green
On indicates that the E-stop is enabled and the
robot can be engaged. Off indicates that the E-stop
is pressed and robot is disengaged and cannot be
re-engaged.
Red
On indicates that the RT-14 Bypass key is in
horizontal position and RT-14 is bypassed. In this
condition both the software E-Stop (from Flair) and
the HHB E-stop have no effect. For safety reasons,
always ensure that this LED is off unless RT-14 is
bypassed temporarily on purpose.
